THE ART OF THOUGHT n JONATHAN CAPE THIRTY BEDFORD SQUARE LONDON FIRST PUBLISHED IN MCMXXVI MADE &? PRINTED IN GREAT BRITAIN BY BUTLER & TANNER LTD F R O M E AND LONDON r~ ycv K. PREFACE During the last twenty years I have from time to time attempted to explore the problem how far the know¬ ledge accumulated by modern psychology can be made useful for the improvement of the thought-processes of a working thinker. I have published chapters dealing with various sections of that problem in my Human Nature in Politics (1908), Chapters II to V, The Great Society (1914), Chapters III, X and XI, and Our Social Heritage (1921), Chapters II, III and IV. This book is intended to be, not a summing up of my earlier attempts, but an extension of my inquiry, par¬ ticularly as regards the less conscious factors in thought. In particular, I have not here dealt with the problem of organized co-operation in thought, which I discussed in Chapter XI of The Great Society. My footnotes and quotations will indicate the psycho¬ logical books which have helped me. But my main material has been derived from my experience, during more than forty years, as a teacher and administrator, and from the accounts of their thought-processes given by poets and others who were not professed psycholo¬ gists, by some of my students, and by friends in England and America. If my book helps a few young thinkers in the prac¬ tice of their art, or induces some other psychological inquirer to explore the problem with greater success than my own, I shall be more than content.

PAGE I PSYCHOLOGY AND THOUGHT 23 Men have recently increased their power over Nature, without increasing the con¬ trol of that power by thought. We can make war more efficiently, but cannot prevent war; we can explore the world, but cannot contrive an interracial world- policy; and the same want of intellectual control exists, within each nation, in politics, philosophy and art. We require, therefore, both more effective thinking on particular problems, and an improved art of thought, in which scientific explan¬ ation may overtake and guide empirical rules. But in thought, as in cookery, science lags behind empiricism, and the study of modern psychological text¬ books may even hinder effective think¬ ing. This fact is largely due to the use by psychologists of the ‘mechanist’ con¬ ception of instinct as ‘power,’ and of reason as ‘machine.’ Some of the best modern physiologists and psychologists are, however, opposed to that concep¬ tion, and substitute for it the ‘hormist’ conception of the human organism as an imperfectly integrated combination of 7 8 SYNOPSIS OF CHAPTERS living elements, each of which retains some initiative of its own, while co-oper¬ ating with the rest in securing the good of the whole organism. The aim of the art of thought is an improved co-ordina¬ tion of these elements in the process of thought. CHAP. II CONSCIOUSNESS AND WILL The thinker must also fight against his own ‘common-sense’ conception of con¬ sciousness and will as simple and abso¬ lute unities. Consciousness varies from ‘full’ consciousness to unconsciousness, and from comparatively unified con¬ sciousness to ‘co-consciousness’; and the thinker must train himself to observe his less conscious as well as his more con¬ scious psychological experiences. Will, also, varies, from full volition to non¬ volition, and from comparatively unified volition to ‘co-volition.’ The distribution of volitional control over the various fac¬ tors in our organism is, indeed, curiously incomplete and arbitrary; so that Plato and others have found difficulty in re¬ lating conscious purpose to creative thought. The similarity of the charac¬ teristics and limitations of consciousness, PAGE 48 9 SYNOPSIS OF CHAPTERS will, and organic life has led many thinkers to believe that they may be three different aspects of the same fact. CHAP. Ill THOUGHT BEFORE ART The art of thought is a modification by conscious effort of a ‘natural’ form of human behaviour. In a civilized adult, it is very difficult to observe mental be¬ haviour apart from acquired habit; but if we make a necessarily rough distinc¬ tion between nature and acquirement, we find that the main ‘natural’ process which the art of thought attempts to modify is the ‘association of ideas,’ which Aristotle and Hobbes observed by ex¬ amining the memory of past association- trains, and Yarendonck and others by the more difficult but more fruitful method of examining association-trains during their occurrence. Varendonck empha¬ sizes the risings and fallings of conscious¬ ness which accompany the ‘natural’ association-trains, and describes the ‘dia¬ logue form’ which results from automatic mental attempts to solve psychological situations. He correlates rising and fall¬ ing consciousness with rising and falling PAGE 59 IO SYNOPSIS OF CHAPTERS rationality; and, less successfully, with the use of verbal and visual imagery. Varendonck’s evidence is influenced by the fact that all his observations took place while he was falling asleep, and also, like that of H. Poincare, by an oversimplified ‘mechanist’ theory of the relation between thought and instinctive emotion. But the thinker, from the re¬ cord of such observations, and from his own introspection, can make for himself a working conception of that natural association-process which his art is to modify. CHAP. IV STAGES OF CONTROL At what stages in the association-process should the thinker bring the conscious effort of his art to bear? If we examine a single achievement of thought we can distinguish four stages — Preparation, Incubation, Illumination (and its accom¬ paniments), and Verification. At the Preparation stage we can consciously ac¬ cumulate knowledge, divide up by logi¬ cal rules the field of inquiry, and adopt a definite ‘problem attitude.’ In Verifica¬ tion we can consciously follow out rules like those used in Preparation. At the PAGE 79 SYNOPSIS OF CHAPTERS ii Incubation stage we can consciously arrange, either to think on other subjects than the proposed problem, or to rest from any form of conscious thought. This second form of Incubation is often necessary for the severer types of intel¬ lectual production, which would be hin¬ dered either by interruption or by con¬ tinuous passive reading. If we are con¬ sciously to control the Illumination stage we must include in it the ‘fringe-con¬ scious* psychological events which pre¬ cede and accompany the ‘flash* of Illu¬ mination, and which may be called Intimation. We can to some degree control Illumination by making our¬ selves conscious (as many poets are conscious) of Intimation; and by both encouraging the psychological pro¬ cesses which Intimation shows to be occurring, and protecting them from interruption. CHAP. V THOUGHT AND EMOTION A difficulty in the voluntary control of thought arises from the elusive character of ‘emotion* or ‘affect.’ Sensation and imagery are less elusive than emotion; and poets and artists have attempted to PAGE 108 12 SYNOPSIS OF CHAPTERS retain their emotions by associating them with images of sensation. On the other hand, emotions can call up ideas, and nations have sometimes to choose be¬ tween a vernacular language whose emo¬ tional associations may provide intellec¬ tual stimulus, and a more exact literary language with fewer emotional associ¬ ations. The intellectual influence of certain emotions, such as humour and sympathy, can best be appreciated by considering them separately. In poetic creation, one of the strongest intellec¬ tual influences comes from the emotion of ‘significance.’ A century ago, the problem of the relation between thought and emotional association was discussed by using the terms ‘reason’ and ‘imag¬ ination’; Shelley described his personal intellectual development from ‘reason,’ which attempted to inhibit emotion, to ‘imagination,’ which used the whole content of consciousness as a guide both to truth and to human values. CHAP. VI THOUGHT AND HABIT All mental activities, beside their imme¬ diate effects in the production of thought, have later effects in the production of PAGE 133 i3 SYNOPSIS OF CHAPTERS mental habits; and it is sometimes con¬ venient to consider the activity as means, and the habit as end. A regular time- stimulus is useful as producing the habit of ‘warming up,’ and may be combined with the stimulus of place or circum¬ stance, or of the muscular movements of fingers or lips. But we should not be¬ come the slaves of habit; the best admini¬ strators often attempt to get a fresh point of intellectual departure by breaking their own mental habits; and those who have to work to a time-table should sys¬ tematically watch and record their unha- bitual ‘fringe-thoughts.’ Such thoughts w'ill often come at moments outside the working day, and it is specially impor¬ tant for the social thinker to observe and select them during newspaper reading. Mental habits should vary with the natural powers, the age, and the subjects of study, of the thinker; and the manage¬ ment of habit is specially important for thinkers who are teachers or journalists. The daily conflict between the stimulus of habit-keeping and that of habit-break¬ ing, is only part of the larger problem of regularity and adventure in the life of a creative thinker. PAGE H SYNOPSIS OF CHAPTERS CHAP. VII EFFORT AND ENERGY Further analysis is required of the facts behind our use in psychology of such words as ‘effort,’ ‘energy,’ and ‘ease.’ Creative artists often describe their moments of greatest intellectual energy as being without effort, but the artist himself cannot always tell whether the absence of effort means an increase or a decline of energy, especially in those cases where a mental activity which origi¬ nally required severe effort has become habitual. Spencer describes a habit of relaxed mental energy, and Mill a habit by which he constantly renewed his men¬ tal energy. But efforts vary not only in intensity, but also in the character of their ‘stroke,’ and many men have wasted their efforts because they never dis¬ covered the right stroke for their work. Sometimes the effective stimulation of mental energy depends on the relation between thought and ‘emotion’; extreme emotion may, however, weaken thought; or the emotional factors in our organism may fail to respond to an intellectual call for energy. Some thinkers have advo¬ cated the production of organic harmony by the general organic relaxation of 150 SYNOPSIS OF CHAPTERS 15 ‘power through repose’; but the purpose of thought is not organic harmony but truth, and the seeker for truth must al¬ ways be prepared to sacrifice harmony. The harmony resulting from action is more effective for the production of energy than the harmony of repose; but action, if it is to heighten intellectual energy, must be relevant to our purpose, and to those conditions outside ourselves on which the fulfilment of our purpose depends. The ‘energy’ of which the psy¬ chologist speaks is an empirical fact of introspection; it may some day be related to the measurable ‘energy’ of the physi¬ cist and the physiologist. chap. page VIII TYPES OF THOUGHT I7I Certain ways of using the mind are char¬ acteristic of nations, professions and other human groups. Some of these are the unconscious results of environment; others have been consciously invented; and others are due to a combination of invention and environment. The French and English nations have acquired differ¬ ent mental habits and ideals which they indicate respectively by the word ‘logic’ and the phrase ‘muddling through.’ 16 SYNOPSIS OF CHAPTERS Each habit has advantages and dangers, and it may be hoped that a new habit will some day be developed which will com¬ bine both advantages and avoid both dan¬ gers. It is less easy to detect an American type of thought. There are indications that a more elastic and effective mental habit may be developing in America than is found elsewhere, but that habit cannot yet be called the national type. The ‘pioneer’ habit of mind is perhaps more prevalent in America than any other single type; but it seems to be rapidly dissolving under the influence of indus¬ trial development, religious change, and the spread of popular interest in psycho¬ logy. A new standard of intellectual energy may ultimately come to be ac¬ cepted in America, accompanied by a new moral standard in the conduct of the mind, and a new popular appreciation of the more difficult forms of intellectual effort. CHAP. IX DISSOCIATION OF CONSCIOUSNESS The history of the art of thought has been greatly influenced by the invention of methods of producing the phenomena of ‘dissociated consciousness.’ The simplest PAGE 204 SYNOPSIS OF CHAPTERS i7 and most ancient of these are the methods of producing a hypnotic trance by the monotonous repetition of nervous stimuli. Such methods have important and some¬ times beneficial effects on the functions of the lower nervous system; and a slight degree of dissociation may assist some of the higher thought-processes; but the evidence seems to indicate that the best intellectual and artistic work is not done in a condition of serious dissociation. Dissociation, however, often produces intense intellectual conviction; and the future of religion and philosophy, in both the West and the East, depends largely on the conditions under which that con¬ viction is accepted as valid. In Western Christianity, methods of ‘meditation’ have been invented, especially by Saint Ignatius, which are intended to avoid the dangers of mere dissociation; but the process of direction of the association- trains of ideas and emotions by an effort of will is so difficult that it constantly re¬ sults in the production of the same state of dissociation as that produced by the earlier and more direct expedient of self¬ hypnotism. And, since dissociation re¬ mains the most effective means of pro¬ ducing intellectual conviction by an act B 18 SYNOPSIS OF CHAPTERS of will, those who now desire to practise the ‘will to believe,’ are still thrown back on the old problem of the validity of con¬ viction produced by dissociative methods. CHAP. X THE THINKER AT SCHOOL The discipline of the art of thought should begin at an age when the choice of intellectual methods must be mainly made, not by the student, but by teachers and administrators. If Plato were born in London or New York, how could we help him to become a thinker? He would be a self-active organism, living and growing in an environment far less stimulating than that of ancient Athens, and unable to discover for himself the best ways of using his mind. His educa¬ tion should involve a compromise be¬ tween his powers as a child and his needs as a future adult; he should acquire steadily increasing experience of mental effort and fatigue, and of the energy which results from the right kind of effort; he will need periodical leisure, with its opportunities and dangers. The present experimental schools in which students are left to acquire thought- methods by their own ‘trial and error’ PAGE 228 SYNOPSIS OF CHAPTERS r 9 have not always been successful, and the individual hints of a clever teacher as to mental method often fail. It may, there¬ fore, be hoped that a knowledge of the outlines of the psychology of thought may become a recognized part of the school and college curriculum; experi¬ mental evidence already exists as to the effect of such knowledge in improving the mental technique of a student. CHAP. XI PUBLIC EDUCATION In the case of four-fifths of the inhabi¬ tants of a modern industrial community, inventions of educational method will only increase the output of thought, in so far as they are actually brought to bear on the potential thinker by the adminis¬ trative machinery of public education. That machinery is everywhere new, and was originally based on an over-simple conception of the problem. In England, we are slowly realizing the necessity, (a) of making more complex provision for the ‘average’ student, and ( b ) of pro¬ viding special treatment for the sub¬ normal or supernormal student. Differen¬ tial public education for the supernormal working-class child had to wait for the PAGE 256 20 SYNOPSIS OF CHAPTERS invention of a technique of mental diag¬ nosis, and only began in England at the end of the nineteenth century; the sys¬ tem is still insufficiently developed, and there is a serious danger that an exten¬ sion of the age of compulsion in its pre¬ sent form may lessen the productivity of the most supernormal minds. If this danger is to be avoided, we must recon¬ sider our present compulsory system, with a presumption in favour of liberty and variety; American experience shows the intellectual disadvantages involved in the compulsory enforcement of anything like a uniform system of secondary edu¬ cation. CHAP. XII TEACHING AND DOING The proposal to raise the age of educa¬ tional compulsion is often combined, in England, with a scheme to make teach¬ ing, like law and medicine, a close ‘self- governing’ profession, with a monopoly of public service. That scheme involves serious dangers to the intellectual life of the community, and especially to the training of potential thinkers; it ignores not only the possible opposition of inter¬ est between the consumers and the pro- PAGE 279 SYNOPSIS OF CHAPTERS 21 ducers of education, but also the ‘de¬ marcation’ problem between the pro¬ ducers of education and the producers of thought. This over-simplification of the problem is partly due to the fact that those engaged in the more general forms of intellectual production are not organ¬ ized, and do not claim, as other profes¬ sions claim, a part in the training for their profession. Experience shows that the teaching of any function is sterilized if it is separated from ‘doing’; but are the English-speaking democracies prepared to offer special and expensive educational opportunities to a small minority of future professional thinkers? Perhaps some local authority might be induced (if legislation closing the teaching pro¬ fession did not, meanwhile, make it im¬ possible) to start an experimental school for students from all social classes who belong to the highest one per cent, in re¬ spect of intellectual supernormality, and who ask to be prepared for a career of professed thought. The staff of such a school would be so chosen as to keep in touch with intellectual work outside the school; the students would be encour¬ aged both to develop their own individ¬ ual talents, and to realize the social sig- 22 SYNOPSIS OF CHAPTERS nificance of their work; and the success of the school might influence the develop¬ ment of a new intellectual standard in other schools. But such an expenditure of public funds would run counter both to professional interests and to many of the traditions of democratic equality, and it may have to wait for a widespread change in popular world-outlook. I PSYCHOLOGY AND THOUGHT It is a commonplace that, during the last two centuries, men have enormously increased their power over^_ nature without increasing the control of that power by thought. In the sphere of international and interracial relations, our chemists and engineers are now contriv¬ ing, by technical methods whose subtlety would have been inconceivable to our grandfathers, plans for the destruction of London and Paris; but when French and British statesmen meet to prevent those plans from being put into operation, they find it no easier than would the leaders of two Stone Age tribes to form a common purpose, and they generally part with noth¬ ing better than a vague hop e that war may be avoided by accident and inertia. The nations of Europe seem unable, even after the Locarno Pact, either to amend the Peace of Versailles, or, if it is not amended, to provide against the danger of a new world-struggle which may be succeeded by such a Dark Age as succeeded the break-up of the Roman Empire. And it is not only in dealing with the master-problem of war that we show t his inability to control by taki ng th ought, our new o powers. We are, for instance, ra pidly learni ng so,to c onqu er insect-borne dise ase a s to make possible the residence of a lar gely increased n umber of w hite men ^ in the tropics; but throughoutTthe great er .part. of. Africa’ neit her the white invaders no r the European^ 23 24 Ch. i THE ART OF THOUGHT governments to which they are nominally subordinate have thought out any better policy than the reduction of the black population to a condition of statutory servi¬ tude^ leading some day to pitiless massacres of masters by slaves and of slaves by masters. In the Pacific no one has produced a scheme for the settlement of thinly- populated territory which is based on any wider concep¬ tion than the separate advantage of competing races and states. I n the sphere of internal policy there Js, within the closely guarded frontiers of every state, a turmoil of new ideas; but those ideas have been so far more successful in weakening the traditions on which out- existing civilization is based than in showing the way towards anything better. The majority of the inhabit¬ ants of Europe now live under constitutions invented by Lenin, Mussolini, Rivera, or by the founders of the German Republic and of the Austrian and Russian succession states; but no one exce pt a few partisan s believes that stable forms of relation between the citizen and the s tate, or between the state and other political and social organizations, have_been_yet invented. In economic life criticism h as far outrun construction; the individu alist, collectivist, and syndicalist conception s of i ndustrial organization have~alT be en discr edited, but no new conception has established itself. In jurispru¬ dence every one laughs at Austin’s utilitarianism and Hegel’s idealism, but no one proposes any substitute for them. In literature, paint ing, and music, aesthetic t radition has been so broken that the young painter or Ch. I PSYCHOLOGY AND THOUGHT 25 poet cannot settle to his work until he h as found his. way through a wilderness o f half-formulated psycho¬ logical theories. In personal conduct, young men and women find that new knowledge has shaken traditional sexual and family morality; but that there is as yet no sign that a period of ethical reconstruction is at hand. The United States of America are more fortunate than the states of Europe, in that they are comparatively safe from external attack; but in American politics, economics, literature, religion, and ethics the difficul¬ ties arising from the failure of human thought to con¬ trive an adaptation of human society to its new environ¬ ment are equally obvious. Thought, therefore , w hether as the con centrated mental activity of the professed thinke r, or as penetrat- i ng and guiding other activities, is now required mope*'"'^ urgently than ever before in the history of mankind.. Thought, if we are to escape disaster, is needed in many specialized fields; we must construct a more accurate and better-proportioned conception of the past; separ¬ ate groups of students must explore biology and physics, politics and sociology, and must try to see the relation of their studies to each other, to the ancient problems of philosophy, and to that beauty of words and form and colour by which our thoughts are made more permanent and more significant; thousands of political and social expedients must be invented. But i n this book I shall argue that we must also consid er . how far itjs possible for us t o improve those processes ’ 0 of thought itself which are used xn all the specialized 26 THE ART OF THOUGHT Ch. i studie s, how far, that is to say, we can produce a more effective art of though t. For the purposes of that inquiry it will be convenient to make a rough division between the more empirical and the more scientific elements in any art — between the methods learnt by each practitioner from his own experience or from imitation of other practitioners, and the wider principles by which those methods can be explained or corrected. So metimes empiricism lags behind science, and sometimes science lags behind empiricism. Seventy years ago, for instance, Baron Justus von Liebig was the acknowledged leader of the chemical science which then claimed to cover the field of the empirical processes of selecting and cooking food; while the chef of the Reform Club might be taken as being a leader of the empirical ‘mystery’ of -^food-preparation, handed on by one chef to another, and indicated in the ‘cookery books’ which were so strikingly unlike the text-books of chemistry. We now know that if in 1855 the Reform Club chef had been asked to prepare the best dinner he could, and if Baron Liebig had been asked to order another dinner, to be prepared in the same kitchen and by the same body of cooks, the chef’s dinner would have been much the better, from the point of view of health as well as of enjoyment. Empiricism was then well ahead of science in the art of cooking, and it was only in 1915, that, owing to t he unrewarded discomforts e.ndnrpd hy srnrrg of small mammals, fed alternately on margarine and butter in the little Wesleyan chapel at Cambridge, the Ch.x PSYCHOLOGY AND THOUGHT 27 chemists demonstrated the importance of the vitamines. Now, perhaps, a professor of bio-chemistry, if he had the necessary modesty and humour, might give a few useful hints to the chef of the Reform Club as to the cooking of fats and vegetables; and might even learn from him, as Darwin learnt from the empirical pigeon- breeders, suggestions leading to new scientific princi¬ ples. The study of atomic structure by the science of physics has been more successful in catching up the empirical processes of tempering and alloying metals, and a trained metallurgical physicist is now an ordinary and useful member of the staff of any large steel-works. Metallurgy is, indeed, a good instance of a sphere of action in which science and practice are now keeping' step, and are producing a rapidly progressive ‘scientific art.’ How, in this respect, do things stand with the ex¬ pedients by which men are helped in the process of thought? How near are we to the creati on of a ‘scientific art’ of though t? Both in our own time and in the past, t hought has, of cour se, been helped by advanc es in t he sciences of logic and mathematics. Roman law, for instance, could not have arisen from the practice of the courts, if Aristotle and others had not first made the science of formal logic; and those methods of contriv¬ ing and interpreting experiments which have produced our modern control over physical nature have had to wait throughout on progress in the science of mathe¬ matics. Even in the sphere of social thought, progress has, in our own time, largely depended upon those 28 THE ART OF THOUGHT Ch. i quasi-mathematical methods of presenting and com¬ paring the statistical results of the relation between independently varying causes which date from the work of Descartes and Leibnitz. And modern thought in all regions has depended for most of its subject- matter on knowledge accumulated and arranged by ‘scientific’ methods. But behind the use by thinkers of rules and materials drawn from the sciences there has always been, since the dawn of civilization, an unformulated ‘mystery’ of thought which has been ‘explained’ by no science, and has been independently discovered, lost, and redis¬ covered, by successive creative thinkers. Plato learnt from Socrates, Sophocles from iEschylus, Masaccio from Ghiberti, Marlowe, Jonson and Shakespeare, or Hamilton and Madison, learnt from each other, some¬ thing which was neither logic nor accumulated know¬ ledge; and Faraday, when he became assistant to Sir Humphry Davy, learnt from his master something which thenceforth changed his use of his mind, and which helped to give efficiency to his thought about those observed chemical and physical facts and mathe¬ matical methods which he also learnt. That ‘something’ lies in the field now claimed by the science of psychology; but a very strong case could be made out for the proposition that a young thinker who should to-day submissively study the current text-books of psychology would be as little likely to improve his work as would have been a young apprentice cook at the Reform Club in 1855, if he had absorbed all Baron Ch.i PSYCHOLOGY AND THOUGHT 29 Liebig’s Organic Chemistry . A thinker can learn from the present text-books of psychology useful hints as to the results of fatigue, as to detailed methods of memoriz-' ing, and as to means of correcting some of the defects of his sense-impressions. But it is difficult for the most patient reader to get much practical help from the existing records of laboratory experiments on the simpler forms of thought; and whoever reads those short chapters on ‘Reasoning’ or ‘Thought’ which in the general psychological treatises cover the whole sub¬ ject of intellectual activity, often fe els as a member of t he audience might feel at an o r g aruecital if the wind-. pressure in the organ sudde nly dropped.- Some, indeed, of the best psychologists warn us that their science can, in that region, offer us no practical help whatever. Professor Pillsbu ry, for instance, is only a little more explicit than some others when he says, ‘ No rules can be given for making the unfertile brain fertile, nor for 1 the better use of the fertile brain .’ 1 ' And, unfortunately, that section of current psycho¬ logy which deals with thought may be not only useless but much worse than useless to the would-be thinker. Psychology has been deeply and necessarily influenced by recent growths in our knowledge of nerve-physio¬ logy, and physiologists and psychologists alike have tended to base on that knowledge a series of summary generalizations, often expressed in clumsy mechanical metaphors, on just that point — the relation of thought to other physiological and psychological processes — 1 W. B. Pillsbury, The Fundamentals of Psychology (1923), p. 4 2 9 - 30 THE ART OF THOUGHT Ch. i where a practitioner of the art of thought requires most exact and guarded statement. Men, for thousands of years, have vaguely connected the psychological events —* of which they were conscious in themselves with differ¬ ent parts of their bodies. To the Greek poets and philosophers pity seemed related to the abdomen, cour¬ age to the beating heart, and intense thought to the diaphragm which controls our breathing. The modern physiologists, by dissection under the microscope of the nerves of men and other animals, combined with obser¬ vation of the behaviour of various parts of the organism under experimental conditions, have concentrated attention on the nervous system. In the primitive behaviour-cycle which begins with the impact of some external stimulus upon a sense-organ, and ends with a movement of the limb-muscles, the physiologists have been able to follow the passage of the stimulation along the ‘afferent’ nerves from the sense-organ to points where they come into relation with the ‘efferent’ nerves, down which the counter-stimulations pass to the muscles. They tell us that when the original stimula¬ tion reaches the spinal cord, it may cause immediate and automatic muscular ‘reflexes’ (such as scratching an irritated place on the skin, or adjusting the limbs to prevent falling) even in an animal the whole of whose brain has been removed. But the stimulation may also reach those more recen tl y e volved nervous outg rowths of the spinal cord w hich are roughly distinguished as the ‘lower’ and the ‘upper’ brain. When it reaches the carpet of interlacing nerves which forms the ‘cortex’ Ch.i PSYCHOLOGY AND THOUGHT 31 or ‘grey matter * of the mammalian upper brain, it sets a sort of telephone-exchange into oper ation, and n ervous events take place w hich appear in conscious- ness as memories and associations and su ggestions. The original sense-stimulus is recognized as part of a ‘situation ,’ 1 and a new message, representing a solution of that situation, may travel back through the lower brain to the nerves attached to the muscles. This cortical message may then give rise to an ‘intelligent’ muscular movement, added to, or modifying, or in¬ hibiting the ‘reflex’ movements which originate in the spinal cord, and the more ‘instinctive’ movements which are related to the lower brain, and are normally accompanied by conscious ‘emotions.’ A scientist born in the second half of the nineteenth century could hardly prevent himself, when describing this series of events, from using terms taken from the behaviour of power-driven machinery. He was almost certain to ask himself what was the ‘power’ in the pro¬ cess, and what was the ‘machine.’ There seemed to be ‘power’ acting within the spinal cord and its related ‘sympathetic’ nerve centres, and revealing itself in the reflex movements; but that power had no apparent con¬ nection with the intelligent element in behaviour. On the other hand, the process of‘association of ideas’ in the upper brain did not seem to reveal much independent 1 See K. Koffka, The Growth of the Mind (1924), and Koehler, The Mentality of Apes (1925), for evidence indicating that i ntelligent m am¬ malian action is stimulated not bv a sensation as such but by a sensation as indicating a ‘situation* calling for action. 32 THE ART OF THOUGHT Ch. i ‘power’ of its own. There remained the intermediate stage of the lower brain with its instincts and their appropriate emotions. These instincts had obvious driving power, and it was undeniable that instinctive impulses often initiated the process of ‘association’ in the upper brain as a means of attaining their satisfac¬ tion. He was apt, therefore, to conclude th at ‘ins tinct, ’ or ‘emotio n,’ or ‘instinctive emotio n’ was the ‘po wer’ r equire d; a nd that ‘intelligence’ or ‘reason* w as the ‘machine.’ Professor J. T. MacCurdy, for instance, says that ‘the static, intellectual functions of the mind ^ are like the mechanisms of the automobile; the emo¬ tional or instinctive functions -are like its thermody¬ namics,’ 1 and Professor MacDougall, in his Outline of Psychology (1923, p. 440 «.), says that ‘it is the paradox of Intelligence that it directs forces or energies without being itself a force of energy.’ Even the great physi¬ ologist, Sir Charles Sherrington, in his Presidential Address to the British Association in 1923, spoke of the human mind as ‘actuated by instinct but instrumented by reason .’ David Hume, writing in 1739, when Hart¬ ley had already started physiological psychology, but before the rise of machine-industry, expressed the same conclusion in terms of the ancient industrial system based on slavery. ‘Reason,’ he said, ‘has no original influence,’ it ‘is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.’ 2 1 Problems in Dynamic Psychology, 1923, p. x. 2 Collected Works, Vol. II, pp. 194-5. Ch.i PSYCHOLOGY AND THOUGHT 33 This ‘mechanist’ co nception of the relation between i nstinct and though t is based on ascertained facts, is ex¬ tremely clear, and is sufficient both for the professor of physiology who is superintending an experiment, and for the professor of psychology who is standing before his black-board, or sitting at his desk and marking examination answers. It is on ly when it is used as am— actual guide to thinking that it breaks down. The generalizations of Baron Liebig as to the chemistry of nutrition also served excellently well for the introduc¬ tory black-board explanations given by the cookery | ^ instructresses when I was a member of the London 1 School Board; and, since neither the instructresses nor * their pupils troubled about them when it was a question of cooking anything, no difficulties arose. In the same way, it is probable that the majority even of the most ‘mechanist’ psychologists, when they are thinking whether a new theory is sound or not, do not often relate their methods of speculation to their belief that their instincts are, and their intelligence is not, ‘a force or energy.’ B ut th ere is on e group of thinkers who have in our own time taken the ‘mechanist’ con - ception of the relation of instinct to reason as a guide for their own intellectual metho ds. T hese are the Marxian Communists in Russia and elsewhere; I have, for instance, before me an admirably written Outline oj Psychology published in 1921 (perhaps with the aid of the Third International) by the Plebs League, who were British representatives of what the book calls ‘the Fighting Culture of the Proletariat.’ Its purpose is 34 THE ART OF THOUGHT Ch. i stated to be ‘to introduce the student to the science of human behaviour, and to the study of the mechanism on which behaviour depends’ (p. i), and it contains many quotations from MacDougall’s works. On almost every page the word ‘mechanism’ occurs once or more, and t he writers con stantly i nsist that thought is a machine, inert in itself, but driven by the force of in¬ stinct. Readers are told tha t they ‘must realize clearly’ that ‘ou r political convicti ons, our moral and ethical codes . . . the class-consciousness of the workers and that of the capitalists; all these are ultimately founded on n on-rational complexes, w hi ch urge us on to the actions we p erform’ (p. 4). ‘Our wants and conations, the strivings of our instincts, emotions, and habits . . . furnish the standard by which the reason judges. . . . ^Reasoning is an accompaniment, but not a cause of action ’ (p. 82); and the whole argument leads to the conclusion that ‘in all crises’ the ‘dictatorship of a small minority’ (p. 98) who have realized these facts is essential. The men who now rule Russia combine this ‘mechanist’ conception of the relation between instinct and reason with a rigid metaphysical dogma of prede¬ terminism, and are able by that combination to con¬ vince themselves that such a ‘bourgeois’ intellectual process as unbiased reflection before one acts in obedi¬ ence to one’s simplest animal instincts, is at the same time biologically impossible, and also biologically possible but politically and economically inadmissible. And they seem determined to stamp out among their fellow-citizens, with the thoroughness of the Spanish Ch. i PSYCHOLOGY AND THOUGHT 3$ I nquisition, all those methods of inventive thought which originally enabled Marx to think and write D as Kapital. The present position, indeed, of the conception of instinct as force and intelligence as machine compels anyone who desires, as I do, to get help for the practical art of thought from the science of psychology, to form a judgment of his own, on the best evidence he can find, as to physiologico-psychological questions which he would normally prefer to leave to the specialized expert. If, therefore, I were told, as a teacher of political science, by a young communist student whose mind had not yet been completely closed by dogma, that this mechanist conception is (whether we like or dislike its political effects) forced on us by the full authority of modern psychology and physiology, I should begin by pointing out that during the last three or four years some of the best psychologists and physiologists seem to have rejected both ‘mechanist’ language on this point and the grossly over-simplified conception of intelligent behaviour to which its use is apt to lead. At the Oxford International Psychological Congress, for instance, of 1923, Dr. C. S. Myers as President protested against the prevailing tendency ‘to suppose that all percepts, ideas and volitions, all forms of cognition and conation, derive their motor effects from the energy which they obtain from related affects. According to some, indeed, this energy is ultimately to be derived from a single affect - the sexual emotion. But the past neglect of instinctive and emotional feelings should not,’ he Ch.i 36 THE ART OF THOUGHT warned the Congress, ‘cause us to overlook the activity involved in perceiving or thinking, or to regard per¬ cepts or thoughts (e.g. ends) as merely inert “mental matter” whose “movement” (nay, whose very “exist¬ ence” in consciousness) is dependent solely on the force of propulsion or repression derived from feeling. Cog¬ nitive and affective experiences are not thus to be isolated in their beginnings.’ 1 I should then ask my young communist to forget that he ever saw a machine, and to c onceive of th e human organism as a combination of livin g elements, all of which tend to co-operate in securing the good of t he organis m (or of the species of which the organism is a temporary representative), but each of which retains some measure of initiative — so that the co-operation is never mechanica lly perfect. I should quote Dr. Henry Head’s statement at the same Congress that ‘the aim of the evolutionary development of the central nervous system is to integrate its diverse and contradictory re¬ actions, so as to produce a coherent result adapted to the welfare of the organism as a whole,’ 2 and should emphasize his assumption that human integration is not complete, and that ‘diverse and contradictory re¬ actions’ do occur. This conception might be easier to employ if all young people had learnt a little physiology )at school. It could then be pointed out to them that l the phagocytes (or ‘white corpuscles’) which wander 1 Proceedings of the Seventh International Congress of Psychology ( P . 188). 2 Ibid., p. 180. Ch. I PSYCHOLOGY AND THOUGHT 37 about in our blood, co-operate with the rest of the organism by surrounding and digesting intruding bacteria; but that in doing so the phagocytes act as living and behaving things, and not as the purely mechanical instruments of a force external to them¬ selves. Each phagocyte, indeed, hunts and digests nearly as independently as if it were an isolated inhabit¬ ant of a warm tropical sea. A man’s hair co-operates with the rest of his organism by protecting his brain from blows and from sudden changes of temperature; but it may go on growing, though the man has ceased * to live. His epithelial cells may begin at any moment to proliferate independently, and so cause death by cancer. Red blood-corpuscles, or patches of skin, trans¬ ferred from one man to another may both continue their own activities and also co-operate in the wider functions of the new organism of which they are now parts. And the same combination of co-operating elements, each of which subserves the good of the whole, while itself retaining some measure of initiative, is found in the functions of the nervous system. When Wood-, worth says of the psychological factors in man that ‘a ny m echanism, except, perhaps, some of the most rudimentary that give the simple reflexes [I should my¬ self reject this exception], once it is aroused, is capable of furnishing its own drive and also of lending drive to other connected mechanisms,’ 1 he is using language drawn from the ‘mechanist’ conception to express the 1 R. S. Woodworth, Dynamic Psychology (1918), p. 67. THE ART OF THOUGHT Ch. i 38 v ery different conception (Tor which I am here arguing) of the co-operati ng parts of an organism as each possess¬ i ng its own drive. The G r eek word forTdriv e’ is ‘ horme,’ a nd therefore Professor T. P. N unn (in his Education , its Data and First Principles, 1920, p. 21) called t his the ‘hormic conception’ or ‘hor mism .’ Hor- mism does not deny that all the parts of an o rgan ism tend towards integrated action. But it substitutes the conception of a living and imperfect tendency towards integration for the conception of a mechanical and per¬ fect integration. The behaviour of a steam engine i s completely integrate d; because the parts of the engin e have no force of their own, and on ly obey the force of the steam from the boiler. The behaviour of the human organism tends towards integration, for otherwise the organism could not, as an organism, exist; but its inte^ gration is not complete, because its parts possess in varying de grees a force of their o wn. 1 1 Though MacDougall is the most influential authority for what I here call the ‘mechanist’ view of the relation between instinct and rea¬ son, he himself, in his Outline of Psychology (1923), pp. 72 and 218, and in an article in Psyche (July, 1924, p. 27), adopts, while arguing against Loeb, Watson, and others, what he calls Nunn’s ‘hormic theory T>f action.’ The explanation of this fact is that t here are three distinc t p roblems in the discussion of which the term ‘mechanism ’ or ‘mechan¬ istic conception’ is used in three different senses. The firs t is the purely metaphysical problem of determinism or contingence, in which the determinist opinion is often called ‘mechanist.’ This problem concerns the whole universe, and therefore no decision in favour either of deter¬ minism or of contingence affects the relation between themselves of any parts of the universe'more than any other parts. The second is the prob¬ lem of‘vitalism’ or ‘mechanism’ in the behaviour of living organisms. Ch.i PSYCHOLOGY AND THOUGHT 39 If the curriculum of our municipal schools also in¬ cluded some instruction in the past history of the evolu¬ tion of living organisms, the difference between the ‘hormic’ and the ‘mechanist’ conceptions of intelligent That problem was w r el l stated by Prof. T. S. H aldane in his presidential address to the Physiological Section of the British Association (1908). He there asked whether the characteristic i nternal and external move¬ men ts of a living cell are due entirel y (as Loeb, for instance, contends) to chemical and physical forces, ox (as Haldane himself contends) toa general purposiveness in the behaviour of living organisms which is not comparable with, and does not interact with the chemical and physical forces. In the discussion of this second problem Loeb’s contention is often called ‘mechanist.’ The third prob lem is the much more limited question which I discuss above. In the case of man and th e other higher mammals, have the functions of the upper brain any initiative ox ‘drive’ of their own (as Myers and Nunn contend), or are they entirely de penden t (as MacDougall, MacCurdy, and others contend) on the ‘drive’ of‘instincts’ arising in the lower brain? I have called MacDou- gall’s answer to this third problem ‘mechanist.’ The clearest statement of that answer appeared originally in his well-knowm Social Psychology (1908), p. 44, and is repeated in his Outline of Psychology (1923), p. 218: ‘The instincts are the prime movers of all human activity; by the conative or impulsive force of some instinct, every train of thought, however cold and passionless it may seem, is borne along towards its end ... all the complex intellectual apparatus of the most highly devel¬ oped mind is but the instrument by which these impulses seek their satisfaction. ... Take away these instinctive dispositions with their powerful impulses, and the organism would become incapable of activ¬ ity of any kind; it would be inert and motionless, like a wonderful clock¬ work whose mainspring had been removed, or a steam engine whose fires had been drawn.’ Professor Mac Doug all is not, I believe, a Marx¬ ist; but as long as he continues to reproduce this passage, lie will be quoted by Marxists all over the world in support of their plea for the necessary subordination of reason to passion. 4 ° THE ART OF THOUGHT Ch. i action could be made clearer by using, as Dr. Head does in the passage quoted above, evolutionary language. The human body is built up of cells, and every human being comes into existence by the repeated splitting of a single-celled fertilized ovum, thereby repeating in outline the evolutionary history of his species. The world contains both single-celled and many-celled animals; and we can, by arranging them in order of complexity and success in cell-co-ordination, trace an unbroken series from the loosely co-operating single- celled protozoa to the highly unified many-celled human organism. In such a series the simplest form of co-operation be¬ tween cells might be represented by a group of single- celled marine protozoa, retaining their individuality except that they are embedded in a common jelly-mass which is propelled through the water by the simultan¬ eous action of their whip-like ‘flagella.’ Next in succes¬ sion might come such ‘colonies’ as those of the coral- protozoa, where the tissues of the members of the ‘colony’ are continuously connected with each other, but where each ‘individual’ (if one may still use the word) is similar in structure to the rest, and follows with independent but roughly co-ordinated variations, a similar behaviour-pattern. Later in the series would come the innumerable species of true metazoa (from the flat-worms to man), in which the structure of the cells of skin and viscera and nerves and bone is so specialized as to fit each of them for the performance of different functions in the life of the organism; and in Ch. I PSYCHOLOGY AND THOUGHT 41 which the behaviour of each part of the organism, though still retaining traces of its ancient independence, is subordinated with an enormously greater degree of success to the behaviour of the organism as a whole. 1 The history, however, of the Russian attempt to found a complete scientific art of thought upon the ‘mechanist’ conception should be a warning to us not, in the present state of physiological knowledge, to make an equally confident use of the ‘hormic’ conception. The Russians and their followers reject on a priori grounds some of the plainest facts of history, and deny the exist¬ ence of some of the most important elements in their own mental experience. Those who prefer the ‘hormic’ conception should for the present be content if it helps them to see more clearly certain observable facts of human intellectual behaviour which the use of mechanist language tends to obscure. One of these facts is that, although what I have called (p. 30) the primitive cycle of psychological events in rational behaviour is carried through with greater vigour and ease than any less primitive course — although when sensation leads at once to impulse, impulse to thought, and thought back again to impulse and muscular action, we are often more intensely alive than when associative thought begins without sensation, or without an impulse from the lower nerve-centres, or when thought ends without action or the impulse to act — yet that cycle is not the only pos¬ sible, nor always, for the purposes of the thinker, the 1 See E. P. Mumford on ‘The Conception of Individuality in Bio¬ logy’ (Science Progress , July, 1925). 42 THE ART OF THOUGHT Ch. i most effective cycle. The cortex of the upper brai n may, for instance, of its own initiative, to satis fy its own need of activity, and to carry out its own function in the organism as a whole, start the process of thought with¬ out waiting for the primitive stimulus of a sensation. When Lord Shaftesbury, in his diary for 18^4, wrote o ne day , ‘Very busy; little time for thought; none for reading. Oftentimes do I look at a book and long foL.it as a d onke y for a carro t; and I, like him, am disap¬ pointed;’ 1 he was describing an impulse to think which was started by the visual sensation of a book, and which owed part of its vigour to that fact. But if Lord Shaftesbury had been compelled to live in a house where he never saw a book, his brain would still, with¬ out any appropriate preliminary sensation, have asserted its need to think. Thought, again, may start, not only without the primitive stimulus of a s ensation, but also without the intermediate stimulus of an ‘instinctive’ impulse from the lower brain. Though a train of mental association may be vigorously driven from link to link by envy of a rival, or pity for a sufferer, it may also start without the aid of an instinctive impulse, and may gain vigour as it proceeds. And just as the upper brain may start it s a ctivity without the stimulus of a sensation or an ‘in ¬ s tinctive’ impulse , so it may conclude its activity with ¬ out having produced that muscular movement which concludes the ‘primitive’ cycle of psychological events. 2 1 Hammond, J. L. and B., Lord Shaftesbury (1923), p. 128. 2 See MacDougall, Outline of Psychology (1923), p. 289. ‘In animals Ch. i PSYCHOLOGY AND THOUGHT 43 A train of thought may die away without any recogniz- able external result of any kind . When Archimede s in¬ vented his test of specific gravity, he ran into the street and shouted; but in the preceding twelve months he must have done a good deal of thinking that left his muscles passive. Dr. J. B. Watson, it is true, and his followers say that any thought of a chess-player which does not cause his hand to move towards the pieces does cause his internal or external speech-organs to move — or rather actually consists of such movements, though they may be both invisible and inaudible. 1 But Dr. Watson’s only proof that his belief is true is apparently the circular argument that if it were not true the extreme behaviourist dogma would be unsound. And the various factors whose co-operation makes up the primitive cycle of intelligent action can not only ‘short circuit’ that cycle by sometimes providing their own drive, but can to some extent overlap each others’ functions, and like the actors in a stock company, play each others’ parts. K. S. Lashley has proved that a rat normally acquires the visual habit of finding its way about a maze by using the occipital part of its cortex; but that, when the occipital part is removed, it can re¬ learn the habit (in about the same number of minutes) and primitively in man every cycle of mental activity expresses itself in the bodily behaviour which is the natural outcome of all conation.’ 1 ‘We do not admit [reasoning] as a genuine type of human behavior except as a special form of language habit.’ Watson, Behavior (1914), p. 319. 44 THE ART OF THOUGHT Ch. i by using another part of its cortex. 1 In the same way, human beings can, apparently, use different proportions of the cortical and non-cortical elements in their central nervous system, while performing what seem to be identical operations. I was, myself, a rather precocious and extremely unmusical small boy. At the age of five I learnt to play The Blue Bells of Scotland on the piano, by a process which I can remember well, and believe to have been entirely ‘cortical.’ Some of my sisters, by making more use of the more ancient parts 2 of their nervous systems, learnt to play with infinitely less corti¬ cal activity, and with very different effects upon their hearers. I am often reminded by these facts of the British Constitution, which it has been part of my professional duty to study. That Constitution has been evolved owing to the need of unifying the social actions of the forty-three million inhabitants of Great Britain. It, like the human nervous system, consists of newer structures superposed upon older, in such a way as to produce both the defect of overlapping, and the compensating 1 Psychobiology, 2, p. 55(1920), and Journal of Comparative Psych¬ ology, 1, p. 453 (1921), and American Journal of Physiology, 59, p. 44 (1922). Owing, I am told, to a peculiarly indefensible application of the post-war ‘axe,’ none of these journals are in the British Museum Library. I have to thank Dr. E. D. Adrian of Cambridge for the refer¬ ences. 2 Presidential address of Sir Charles Sherrington to the British As¬ sociation, 1922: ‘the chief, perhaps the sole seat [of mentality] is a com¬ paratively modern nervous structure superposed on the non-mental and more ancient other parts’ [of the nervous system]. Ch. i PSYCHOLOGY AND THOUGHT 45 advantage of elasticity. The oldest part of our Consti¬ tution provides that we shall be governed by our king, whom God has caused to be born from his father, and who has been anointed in Westminster Abbey by our chief priest. The king still chooses his ministers, as he did when he was the only source of authority. Before the king, on the advice of his ministers, directs his sheriff to hang or imprison a man, he makes use of an almost equally old system, trial by jury. Twelve peers of the prisoner, chosen by the supernatural indication of the lot, are sworn to tell the truth about him by oaths which bring them into danger of supernatural penalties. On these older parts has been superposed a newer system, which provides that we shall be governed by a Parliament, elected by the men and women on the regis¬ ter, and acting through ministers responsible to it. On Parliament itself has been superposed a still more recent system, in which the main work of government is done by civil servants and military officers chosen by com¬ petitive examination, and by professional judges and magistrates chosen by the ministers but exercising inde¬ pendent authority. Many constitutional text-books have been written in which all these facts are represented as a neatly dove¬ tailed mechanical arrangement, in which each decision is taken by an undisputed appropriate authority, and no question is left undecided. But a British politician who determined to act on that conception would certainly be a political failure. He could only succeed by remem¬ bering that the relation between the parts of our Consti- 4 6 THE ART OF THOUGHT Ch. t tution is never simple, and is constantly changing. A certain degree of responsibility of the ministers to the monarch persists, and influences the working of their responsibility to Parliament. In time of war the control of Parliament over the civil executive and the army may be almost completely suspended, and the Commander- in-Chief may refuse to tell his plans to the Secretary for War. No one knows whether the next English bishop will really be chosen by the prime minister, or by the king, or by the Archbishop of Canterbury, or by a subtle balance between authorities each of which is in its origin and on its own principles supreme. And if one authority, from ill-health or incompetence or some external crisis, ceases to function, another silently takes its place. I n Britain, therefore, the art of gove rnment is not that mechanical process of driving an inert machine by the force of a single sovereign wil l, of which rulers like Lenin and Mussolini constantly dream , but the delicate talk of co-ordinating the actions of partially indepen¬ dent living organisms. And all the psychological and physiological arts by which unity of action is to some degree secured within the individual human organism are of this type. Mr. Harry Vardon, for instance, in his book How to -play Golf (1912), says (p. 62) that after a year of constant experimentation he discovered a grip which ‘seems to create just the right fusion between the hands, and involuntarily induces each to do its proper work.’ Mr. Vardon’s language would not perhaps satisfy exact psychological analysis, but he has the root Ch. I PSYCHOLOGY AND THOUGHT 47 of the matter in him. By his use of the words ‘fusion’ and ‘involuntarily’ he means that he has at last ac¬ quired an art which enables him, when he grips his brassy, to unify the behaviour of certain partially inde¬ pendent elements in his organism; and the thinker who is about to grip his problem has to acquire a similar art. II CONSCIOUSNESS AND WILL But the thinker who desires to get help in the practice of his art from the science of psychology should not be content to avoid the hindrances which arise from the hasty generalizations of some modern psychologists. He should also, I believe, t ry to rid himself of that ‘commonsense’ notion of his conscious self as a com¬ pletely integrated unity which he will have formed before he ever heard that a science of psychology exists. Mr. Harry Vardon, when he is practising a new grip, does not, unless he has been reading MacDougall’s Social Psychology or the Plebs text-book, believe that his instincts and his intelligence have to each other the simple relation of power and machine. He finds that he is not successful unless he recognizes more or less clearly that his hands, wrists, eyes, nerves, feelings, and ideas all have ‘power’ of their own; and that, if he is to achieve that measure of harmonious organic co-opera¬ tion on which excellence in golf depends, he must act on the assumption that in that respect he can only hope to improve an imperfect tendency towards unification. But he will nevertheless assume that he himself, the essential Harry, the person who wills to improve his grip, and is conscious that he wills it, the person who looks out every morning through the eyes in his shaving mirror, is a simple unity. That assumption will not hurt Mr. Vardon’s golf; 4S Ch. 2 CONSCIOUSNESS AND WILL 49 but the professed thinker, if he is to control some of the most important elements in his intellectual processes, must so far get behind his own commonsense as to sub¬ s titute _an explicit conception of his conscious self~as an imperfect and improvable tendency towards unity for @ the tacit assumption that his conscious self is an already completed uni ty. In order to do so, he should begin by forcing himself to realize the existence of an un¬ broken series of grades from unconsciousness up to the highest level of consciousness which man has yet reached. We can, for instance, watch the g rowth and decay in our own lives of our own personal conscions- ness. Memory seems to us to be an essential element in consciousness, and if the consciousness of any one moment is not joined to the consciousness of the follow¬ ing and preceding moments, we can hardly conceive of it as consciousness at all. Yet our memory of con¬ sciousness goes back, perhaps, only to the end of our third year; and if we watch a laughing child of one year old, we cannot help believing that vivid conscious¬ ness must there exist without continuous memory. Nor can we draw a line at any point between consciousness at the age of one, and consciousness or quasi-conscious¬ ness immediately after, or even immediately before birth, or fix a point in the growth of the human embryo where potential quasi-consciousness turns into actual quasi-consciousness. Nor, in the non-human world, can we draw a line between the apparently intense con¬ sciousness of a fox terrier or a lark, and the quasi¬ consciousness of a newly-born puppy or of a fish or D Ch. 2 50 THE ART OF THOUGHT worm. At the end of life, we can draw no line between the second childhood of extreme old age, the quasi-con¬ sciousness of delirium, the unconsciousness of coma or of functional death, and the non-consciousness of irre¬ vocable death. 1 At least once every twenty-four ho urs we pass through all the grades from consciousness t hrough foreconsciousness to unc onsciousness, white going to sleep, and back again while waking u p. We are further becoming aware that consciousness not only may be graded on a single series from complete uncon¬ sciousness to the highest grade of consciousness yet reached, but also may exist in forms parallel to that series. Hypnotists and psychiatrists have, for instance, proved that in the same person there may be, either successively or simultaneously, two or more ‘dissoci¬ ated consciousnesses/ or ‘co-consciousnesses/ 2 C onsciousness, indeed, shows all the signs of having reached, as yet, only an early, imperfect, and confused 1 In this case, as in the case of most graded psychological and bio¬ logical facts, we are hindered in thinking or writing . clearly hy..thfi de¬ fects of our vocabulary. We have hardly any words expr_essing_gr&lgg in consciousness. AH that psychologists have yet done is to name two Extremes, ‘consciousness* andAmconsciousness,’ and to insert between them a single vaguely conceived intermediate grade called ‘subcon¬ sciousness,’ or (in Freudian language) ‘foreconsciousness.’ 2 One may be helped to avoid the ‘common-sense’ assumption that consciousness is necessarily absolute and necessarily individual by trying to imagine other kinds of consciousness than our own, say, in the tem¬ perate latitudes of the planet Mars. There may there, perhaps, be acres or square miles of confluent protoplasm, in which consciousness exists, | but i s no more permanently individualized than are the wave-shapes of 1 t he se a or the life-shapes in the Buddhist universe. Ch. 2 CONSCIOUSNESS AND WILL 51 st age in its evolution . The distribution, for instance, of consciousness over the physiological and psychological events which make up our daily life is strangely arbi¬ trary. Every conscious dv^nt can have analogues be¬ neath the level of consciousness. We can unconsciously, or foreconsciously, or co-consciously, experience events which, if they were fully conscious, we should call sen¬ sations, or perceptions, or impulses, or thoughts; and in every grade of consciousness we can move our limbs, or compose poems, or discover mathematical solutions. We are, as a rule, unaware of this fact, because we either do not observe or soon forget all mental events outside the limits of full consciousness. In the case of mental events which are so far removed from full con¬ sciousness as to be called ‘unconscious,’ we can only observe them by hypnotism, ‘free association,’ or some other method of tapping the unconscious memory after the mental event has occurred. In the case of less com¬ plete defect of consciousness, we can sometimes observe a foreconscious event while it is going on. In explain¬ ing how we can do this, psychologists find it convenient to use terms drawn from the facts of eyesight. The ‘field of vision’ of our eyes consists of a small circle of ^ full or ‘focal’ vision, surrounded by an irregular area of ‘peripheral’ vision, which is increasingly vague and im¬ perfect as the limit of vision is neared. We are usually unaware of the existence of our peripheral vision, be¬ cause as soon as .anything interesting presents itself there we have a strong natural tendency to turn the focus of vision in its direction. We can, however, by a Ch.2 52 THE ART OF THOUGHT rather severe effort, inhibit that tendency, and so observe objects in our peripheral field of vision. Using these terms, we can say that one reason why we tend to ignore the mental events in our ‘peripheral’ conscious¬ ness is that we have a strong tendency to bring them into ‘focal’ consciousness as soon as they are interesting to us, but that we can sometimes by a severe effort keep them in the periphery of consciousness, and there t observe them. Closely allied to the problem of our working concep¬ tion of consciousness is the problem of our working conception of will. Just as consciousness shades imper¬ ceptibly from full consciousness through forecon¬ sciousness to the apparent non-consciousness of the simplest animal behaviour, and from unified conscious¬ ness to completely or partially dissociated ‘co-conscious¬ ness,’ so full volition_shades imperceptibly, through what I may call ‘fore-volition,’ to the apparent non¬ volition or automatism of the simplest animal behaviour; and, on another line of gradation, from unified volition to that dissociated volition which I may call ‘co-voli¬ tion.’ It is, indeed, a delicate question of verbal defini¬ tion both at what point we shall cease to give the name ‘will’ to the less continuous and less unified forms of conscious conation (whether we shall, for instance, say that an excited dog wills to dig at a rabbit-hole, or a hungry infant wills to scream), and at what point in an equally imperceptible gradation we shall distinguish between conscious conation itself and the mere ‘urge’ of the simplest forms of protozoal and cellular life. Ch. 2 CONSCIOUSNESS AND WILL 53 Even the trained, comparatively unified, and continu¬ ous will of an educated civilized man shares that quality of incompleteness and arbitrariness which appears in the analysis both of consciousness, and of the co-ordina¬ tion (which I discussed in Chapter I) of all the factors of organic life. An unconscious desire may, for in¬ stance, mask itself as a conscious will, whose character gives us little or no hint of the underlying process. And an equal arbitrariness characterizes the limits of the control of our will over our external and internal behaviour. If we decide to perform such a bodily act as taking up a book, or walking in this or that direction, we do so, if we are in good health, with such easy and complete control that the will to act and the act itself almost seem to be the same event. We can with equally complete control direct and focus our sight, or move our tongue. Few people can, however, by the most intense effort of will, influence appreciably the rate of their pulse, or the process of digestion, or the functions of their thyroid, or suprarenal, or even lacrymal glands; and in some cases the effort of will is a positive hin-j drance to the production of the desired events. 1 The same is true of those of our activities which , without dogmatizing as to the ultimate relation between body and mind, we may call ‘mental.’ The mental pro¬ cess of attention is, for instance, like the related bodily act of eye-focussing, very completely controllable by our will; and, indeed, the development of the will itself 1 See e.g. Baudouin, Autosuggestion (2nd English edition, 1924), p. 37: ‘I n a word , the more we wish, the less are we able.’ Ch. 2 54 THE ART OF THOUGHT may, on its physiological side, have been closely related to the development of attention. On t he oth er hand, our feelings are very little under the control of our will. We cannot by a direct effort of will make sure of feeling happy, or sorry, or angry, or grateful, at any given moment, or in any particular situation. It is easy for us, again, to learn voluntarily ‘by heart,’ while making repeated acts of attention combined with the formation of silent speech-images; and we can often by a single effort of will remember a name which we have for¬ gotten, or find the answer to a simple problem. But the mental processes which constitute the higher forms of thought, and which lead to the formation of new and useful ideas or decisions by distant and unaccustomed links of association, are very imperfectly controllable by any direct effort of will. The most perfectly trained scientist or poet can no more be sure that he will be ab]e to make his mind produce the solution of a complex problem, or a new poetical image or cadence, or a ready original sonnet on the death of a monarch or a presi¬ dent, than can the most perfectly trained clergyman be sure that he will feel really sad at Tuesday’s funeral s or really joyful at Thursday’s wedding. It is this fact which leads to such pessimistic statements about the impossibility of improving thought by conscious art as that which I have already quoted from Pillsbury. 1 If our will is un able to control the more important pro- cesses of thought, an art of thought cannot exist. T his was the problem which constantly torment ed 1 See above, p. 29. Ch.2 CONSCIOUSNESS AND WILL 55 Plato. The whole universe was to Plato only intelligible if it was seen as an imperfect expres sion of a divine, moral idea; and Plato’s favourite illustration of moral conduct was the voluntary subordination of the crafts¬ man’s skill to the craftsman’s conscious purpose. But conscious purpose seemed to Plato to have surprisingly little connection with the production of poetry, or with t he other highest achievements of the hu man mind . Plato himself was a great poet, with ample personal experience of poetic inspiration; and he lived in Athens at the close of the greatest poetic outburst that the world has ever seen. He was also, as far as his love for truth would allow him, a religious conservative, who hoped to see a moral direction for the distracted city- states of Greece develop out of the trance-utterances of the Delphic oracle. But neither the Athenian poets nor the Delphic priestess (who, when awakened from her trance, might be a very uninteresting person) could, he found, give any account, in terms of conscious volition, of the processes by which their ideas came to them. In the Re-public Plato tried to solve the resulting practical problem by forbidding, throughout his ideal state, all poetry except ‘hymns to the gods and panegyrics on good men .’ 1 In the Pliadrus, he put forward a half- serious, half-ironical theory that creative thought was a kind of madness, sent upon men by the gods in accor¬ dance with some purpose of which the gods and not men were conscious. The Greek words for insanity and inspiration (manike and mantike) were, he suggested, 1 Republic, p. 607. jlKA.dAt***' THE ART OF THOUGHT Ch.2 56 derived from the same root. ‘We_Grgsks,’ he said, ‘owe our greatest blessings to heaven-sent madness. For the prophetess at Delphi and the priestesses at Dodona have in their moments of madness done great and glori¬ ous service to the men and cities of Greece, but little or none in their sober mood .’ 1 There is a deeper irony in his description of the ‘madness inspired by the Muses,’ ‘ which seizes upon the tender and virgin soul’ of the poet, and distinguishes him from that industrious apprentice to the art of letters, whom Plato the poet, in spite of the theories of Plato the moralist, cannot help despising. ‘He who having no touch of the Muses’ madness in his soul comes to the door, and thinks that he will get into the temple by the help of art, he, I say, and his poetry are not admitted; the sane man is nowhere at all when he enters into rivalry with the madman .’ 2 Indeed, throughout the whole phenomena of con- sciousriess. will, and life , we see the same puzzling tendency towards unity, limited by the same kinds of imperfection. This fact is apt to make not only a non¬ physiologist like myself, but some of the best modern physiologists wonder whether physiology may not ulti¬ mately give us a working conception of consciousness, will, and life as being the same thing. Professor Julian Huxley, for instance, expresses his belief ‘that some¬ thing of the same general nature as mind in ourselves 1 Phadrus, 244. See also F. C. Prescott, The Poetic Mind (1922), p. 294. 2 Phadrus, 245. Ch.2 CONSCIOUSNESS AND WILL 57 is inherent in all life, something standing in the same relation to living matter in general as our minds do to the particular living matter of our brains’ ( Essays of a Biologist (1923), p. 242). An unbridged gulf still, it is true, exists between our conceptions of life and non¬ life, of the behaviour of the atoms that are building up the most complex crystal, and of those which are build¬ ing up, from its original germ, the simplest living cell. But there seems to be a tendency (strengthened by recent work on atomic structure and movement) topass over that gap, not b y extending, as Loeb a nd Watson have don e, our conception s of non-life to life, but by ^ extending our conceptions of life to non-life. Professor 1 7 S. Haldan e, for instance, writing as a physiologist, says ‘it is at least evident that the extension of biological conceptions to the whole of nature may be much nearer than seemed conceivable a few yearsjtgo’ (Mechanism, Life and Personality (1921), p. 101); ‘We cannot re¬ solve life into mechanism, but behind what we at pre¬ sent interpret as physical and chemical mechanism life may be hidden for all we yet know’ (Mechanism, Life and Personality , p. 143); and ‘That a meeting-point between biology and physical science may at some time be found there is no reason for doubting. But we may confi¬ dently predict that if that meeting-point is found, and one of the two sciences is swallowed up, that one will not be biology’ (The New Physiology, 1919, p. 19). Pro¬ fessor A. S. Eddington, again, wrote as a mathematical physicist in 1920 that ‘all through the physical world runs that unknown content, which must surely be the Ch. 2 58 THE ART OF THOUGHT stuff of our consciousness’ {Space, Time and Gravitation , p. 200). And, in the same way, it is becoming increas¬ ingly difficult for a psychologist to maintain the dis¬ tinction between his conceptions of ‘body’ and of ‘mind.’ If we are compelled by thousands of years of tradition still to use the old words, we must at least say with Dr. Henry Head that ‘mind and body habitually respond together to external or internal events,’ 1 and with Watson, ‘a whole man thinks with his whole body in each and every part.’ 2 But I myself find that the nearer I get to the statement t hat body and mind are two aspects of one life, the greater is my sense of reality. And Donne comes very near that statement in the mag¬ nificent lines in which he describes a blushing girl: ‘Her pure and eloquent blood Spoke in her cheeks, and so distinctly wrought That one might almost say her body thought.’ 3 1 Oxford Psychological Congress, 1923, p. 180. 2 British Journal of Psychology , Oct., 1920, p. 88. 3 An Anatomy of the World , line 244—Donne’s Poems (Bullen, Vol. n, p. 135)- Ill THOUGHT BEFORE ART The art of though t, like the art of running, or the actor’s art of significant gesture, i s an attempt to im¬ prove by conscious effort an already existing form of human behaviour. Men ran for countless generations, before they invented or handed down t he few expedi¬ ents which constitute the art of running as taught by. professional athletic trainer s; they revealed their feel¬ ings by gestures long before there were any schools of dramatic art; and they thought for thousands of years before they had a name for thinking. In all these cases, therefore, the rules of art must be based on the most exact knowledge which we can obtain of the behaviour which the art is to modify. Sometimes that behaviour is completely ‘natural’; the teacher, for instance, of running, or of breathing-exercises, starts from behaviour which is mainly directed by the sympathetic nervous system, and which contains hardly any ‘acquired’ elements. But when the co-operation of the higher nervous system is involved, it is, under the conditions of modern civilization, almost impossible to observe any instance of human behaviour which is entirely free, and extremely difficult to observe any instance which is even approximately free from acquired elements. Many, in¬ deed, of the innate tendencies of the higher nervous system, such as the tendency to speak, represent rather a power and an inclination to learn to behave in a cer- 59 6 o THE ART OF THOUGHT Ch. 3 tain way, than a direct instinct to behave in that way. Such learning may proceed rather by half-conscious imitation than by conscious effort; and the result even of repeated conscious effort may be a habit which it is not easy for an observer either of his own or of other people’s behaviour to distinguish from a natural ten¬ dency. An actor, for instance, can only with the greatest difficulty form any estimate as to how far his move¬ ments while he acts are ‘natural,’ and how far they are due to acquired modifications of nature. Sometimes he can be helped by observing the gestures of less sophisti¬ cated persons than himself; he can watch the behaviour of children; and he could, before the cinema had soaked whole populations in third-rate theatrical conventions, go down to the East End of London on a Saturday night, and watch the comparatively natural behaviour of uneducated people who were under the influence of rage or jealousy, and some of whose acquired social habits had been temporarily weakened by alcohol. Or he may try to recall his own behaviour on some occasion when he was ‘off his guard’; or, if he has unusual powers of imagination, introspection and inhibition, he may stand before a looking-glass trying to believe that he is Othello or Lear, and to inhibit all acquired elements in the gestures which follow from that belief. The thinker, when he is trying to observe thought in its most natural form, is faced with even greater diffi¬ culties than the actor who is trying to observe natural gesture. Some of the most important steps in the pro- 6 i Ch. 3 THOUGHT BEFORE ART cess of thought are normally unconscious or half-con¬ scious; and our unconscious or half-conscious thought, even if we succeed in observing it, is not necessarily ‘natural.’ The subject-matter, again, even of our least conscious thought is mainly derived from past experi¬ ence, and is deeply influenced by intellectual and emotional habits; and thought at all grades of con¬ sciousness makes large use of language with its innum¬ erable acquired associations. The student, therefore, of the art of thought has to choose a more or less arbitrary point from which he shall assume the conscious effort of the art to begin. I myself shall, in this and the following six chapters of my book, assume that I am addressing young adults who have already learnt, at home or at school, to speak, read, attend, and memorize, but who, though they do in fact constantly reach new ideas by using their brains, have never yet attempted to acquire or to apply a conscious art of thought. I shall post¬ pone till the last three chapters of the book the problem of that preliminary training in the art of thought which may be given by teachers and others to children and adolescents. The young adults whom I imagine myself to be addressing will, in spite of differences in their acquired experience, be alike in that the esse n tial el ementin their inventive thou ght is the process fa y which, as I have already stated, o ne psychological event calls up ano ther in the ‘telephone^ ex change’ of the upper brain . It_is t his process of ‘association’ whichtheir art will attempt to improve^ and which they must first try to observe and 62 THE ART OF THOUGHT ' Ch. 3 understand. The process of association has been ob¬ served introspectively by two methods - the observer has either remembered a train of association after it has occurred, or he has watched it while it is occurring. The first method is by far the easier, and up till our own time has been almost exclusively used. Aristotle, in¬ deed, in the earliest recorded discussion of the associa¬ tion-process, treats association as a section of the prob¬ lem of memory. He asks himself why the memory of one experience calls up the memory of another. ‘For,’ he says, ‘experiences habitually follow one another, this succeeding that, and so, when a person wishes to recol¬ lect, he will endeavour to find some initial experience to which the one in question succeeded.’ 1 He concludes that experiences call each other up, sometimes because they succeeded each other in time, sometimes because the experiences were similar, or contiguous in place, or were connected logically as are the steps in a mathe¬ matical proof. The best-known description of a train of association as seen in memory is that given by Hobbes in a classical passage of his Leviathan (Chapter III, written about 1650). The passage forms part of a discussion of the type of thinking which Hobbes calls a ‘train of thoughts, or mental discourse . . . “unguided,” “without de¬ sign and inconstant.’ ‘And yet,’ he says, ‘in this wild ranging of the mind, a man may ofttimes perceive the 1 Aristotle, De Memoria, II, 12. This difficult passage has been admirably translated and explained by Prof. Howard C. Warren in his History oj the Association Psychology (1921), pp. 25 and 26. Ch. 3 THOUGHT BEFORE ART 63 way of it, and the dependence of one thought upon another. For in a discourse of our present civil war, what could seem more impertinent, than to ask, as one did, what was the value of a Roman penny? Yet the coherence to me was manifest enough. For the thought of the war introduced the thought of delivering up the king to his enemies; the thought of that brought in the thought of the delivering up of Christ; and that again the thought of the thirty pence, which was the price of that treason; and thence easily followed that malicious question; and all this in a moment of time; for thought is quick.’ In his explanation of the connection between link and link in such a train Hobbe s is here less full than Aristotle, and confines himself to succession in time — ‘i n the imagining of anyt hing,’ he says, ‘ there is no certainty what wc shall imagine next; only this is cer¬ tain, i t shall be something that succee ded the same before, at one tim e or another.’ In these passages, neither Aristotle nor Hobbes dis¬ tinguishes between the relation to each other of psycho¬ logical events, and the relation to each other of the external facts which give rise to the psychological events. The likeness between the treachery of Judas and the treachery of the Scottish leaders seemed a sufficient ex¬ planation of the calling up of one by the other, without asking why the mind of the speaker was interested, even during ‘unguided’ thought, in that kind of likeness. This over-simplification of the problem was made easier by the fact that neither Aristotle nor Hobbes recognized the existence of psychological causes which 64 THE ART OF THOUGHT Ch. 3 were not conscious. And the over-simplification was increased when, after the publication of Locke’s Essay Concerning Human Understanding in 1690, psycholo¬ gists came to use the term ‘The Association of Ideas’ for the whole association process, and to define ‘ideas’ as copies, in conscious memory, of events. 1 Hobbes himself, however, realized that the path of association might in some cases be directed, not merely by the external connection between remembered facts, but also by the drive of passion in the thinker himself. These cases he classed as ‘regulated’ thought. ‘For the impression,’ he says in the same chapter, ‘made by such things as we desire, or fear, is strong, and permanent, or, if it cease for a time, of quick return; so strong it is sometimes, as to hinder and break our sleep. From desire, ariseth the thought of some means we have seen produce the like of that which we aim at; and from the thought of that, the thought of means to that mean; and so continually, till we come to some beginning within our own power. And because the end, by the greatness of the impression, comes often to mind, in case our thoughts begin to wander, they are quickly again re¬ duced into the way.’ And, as I pointed out in Chapter I, 1 Professor H. C. Warren points out ( History of the Association Psy¬ chology, p. 5) that: ‘When Locke speaks of the association of ideas he has reference to possible connections between all sorts of mental content ; whereas from the time of David Hume onward the phrase refers to con¬ nections between representative data only. . . . This permanent fixing of the expression association of ideas with an altered meaning given to the term idea has exerted some influence on the development of the doctrine itself.’ Ch. 3 THOUGHT BEFORE ART 65 many modern psychologists have tended to simplify the problem in another way, by treating Hobbes’s special class as universal, and by declaring that the mechanical drive of some one of a list of instincts is*"^ invariably requisite before connection can be made between one link of association and another. The second method of observation, in which the ob¬ server watches the association-process while it is going on, instead of remembering and explaining it when it is past, is much the more difficult; but it is much less likely (if the observer can prevent himself from distort¬ ing his observations by theories as to their causes) to lead to an over-simplified conception of the association- process itself. Fifty years hence, students will have an ample supply of this kind of observation before them ; but for the moment the supply which I have been able to discover is curiously small. The experimental associa¬ tion-trains which are deliberately started and observed in psychological laboratories are limited in range, and are often distorted by the ‘unnatural’ conditions of their formation; and the clinical observations recorded by the professional psycho-analysts seem to me to lose most of their evidential value owing to the influence of the sug¬ gestion of the psycho-analyst upon his patients, and to his own conscious or sub-conscious determination to^- defend, against outside critics, the dogmas of his pro¬ fession. The most useful (from the point of view of the would-be thinker) of modern introspective evidence on the ‘natural’ association-process, which I have met with, is that contained in Dr. J. Varendon ck’s Psychology, of. E 66 THE ART OF THOUGHT Ch. 3 Day Dreams , written by himself in English, and pub¬ lished in 1921. Dr. Yarendonck, who was attached as an interpreter to the British army in Belgium, was, before the war, a lecturer on pedagogic psychology. During the war he trained himself to observe, night after night, the ‘foreconscious’ events in his mind which immediately preceded sleep, and which were not initi¬ ated or controlled by any conscious effort of will. He was able both to watch these trains of thought, which he calls day-dreams, without allowing them to be in¬ fluenced by the fact that they were being watched, and also at the right moment to wake himself, by a strong effort, into complete consciousness, and record his observations. His day-dreams deal mainly with the hopes and fears and annoyances of camp life; and they are set down with a courage and candour which compel the admiration of anyone who has tried, as I have, to do the same thing, and who, partly from want of equal courage, has failed. Varendonck’s first observation was that ‘there occur in most of our day-dreams risings and fallings’ (p. 176), or ‘successive risings to the surface and sinkings into the unconscious’ (p. 155). A day-dream, he says, may last for a considerable time, and during that time, several such ‘risings and fallings’ of consciousness may take place, before the process is interrupted either by sleep or by a return to complete consciousness. He gives (pp. 170—2) a description, written down imme¬ diately after its conclusion, of a day-dream which lasted fifty-five minutes, and in which ‘on six different occa¬ sions the association had risen close to consciousness.’ THOUGHT BEFORE ART 67 Ch. 3 Varendonck carefully analyses a few of his longer day-dreams, or, as he sometimes calls them, in Freudian language, ‘phantasies .’ The most interesting for our purpose belonged to the type which is often called ‘mental trial and error’; that is to say they were part of an automatic mental attempt to solve a difficulty by imagining successive solutions. And just as the muscu¬ lar ‘trial and error’ process comes to its conclusion when some one among a series of movements is successful, so the ‘mental trial and error’ process found, in Varen- donck’s case, its normal conclusion in t he mental recog¬ n ition that the solution thought of would he successful if trie d. I n thinking of this recognition I find that I t end to use the word ‘click ,’ in the slang sense common among English school-boys and soldiers. This term spread during the war, when every young soldier was being trained to use, by a process containing a large element of muscular ‘trial and error,’ a number of machines from rifle-locks upwards. The ‘click’ was the sound made by the machine when the successful move¬ ment was made, and the verb ‘to click’ meant, for in¬ stance, to succeed in such matters as obtaining by verbal ingenuity an irregular week’s leave. In its origin, the click feeling must have been due to the fact that a fore¬ conscious or unconscious train of association had led to a point which revealed the need of action, and therefore the need of full consciousness. It is the same thing as the extremely painful shock which occurs when a casual train of association suddenly reveals to us that we are on the point of missing an important 68 THE ART OF THOUGHT Ch. 3 engagement. 1 The feeling itself varies from joy or horror to a mild recognition that the search is over. But the process of association may lead not only to a recognition that an imagined solution of the situation will result in successful action, but also to a preceding series of recognitions that other imagined solutions will not succeed. Varendonck, therefore, speaks of the ‘dia¬ logue form’ of sections of his day-dreams, in which successive proposed solutions presented themselves, and were met by successive objections, until some solu¬ tion appeared against which no valid objection sug¬ gested itself. 2 ‘A foreconscious chain of thought,’ he 1 It would be interesting if some student of comparative psychology could discover whether the process of cerebral association is ever suffi¬ ciently advanced in an intelligent dog, to produce any indication of the ‘click’ phenomenon. Does the dog’s whole organism ever recognize that his mind has discovered the need of immediate action? Do, for instance, the dog’s endocrine glands ever discharge their hormones into the blood-streams as the result of a train of association, starting, as human ‘day-dreams’ may start, in the mind, or only when the train of association is started by a sensation - the sight of a rat, or the smell or step of his master - as Lord Shaftesbury’s train of association was started by the sight of a book? (above, p. 42). 2 At the threshold between dreaming and foreconscious thinking the critical faculty may have a strong negative power over the train of association with no positive power of directing the train. I, as a child, used often to continue my dreams into a foreconscious state which pre¬ ceded full awakening. I used then to notice that if I was vaguely aware that a lion was about to appear round the corner of the street in which I was walking, I could prevent the appearance of the lion, but could not cause anything else chosen by me to appear. Ch. 3 THOUGHT BEFORE ART 69 says (his argument shows that he means a foreconscious chain of thought comparatively near full consciousness), ‘is a succession of hypotheses and rejoinders, of ques¬ tions and answers, occasionally interrupted by memory hallucinations’ (p. 179). He gives a long and amusing analysis of a day-dream in which his foreconscious mind attempted to deal with the situation created by the fact that he desired to get an impertinent orderly punished. The orderly was attached to a Belgian Field Hospital, of which a certain formidable Lady V. was matron, and where ‘the chief medical officer was practically at her mercy’ (pp. 64— 76). Varendonck had already reported the orderly to his own superior officer, Major H. But the orderly had threatened him with Lady V.’s vengeance. Varendonck imagines in succession such expedients as writing to Lady V. before she can hear the orderly’s story, lending weight to his letter (which he begins to compose) by accompanying it with his visiting card (with his civilian professional status indicated on it), or getting a friendly Belgian captain to send the letter to Lady V. by his cor¬ poral. Some of these expedients were mentally accepted, and some rejected; until Varendonck remembered, in consequence of a detailed visual picture of the comfort¬ able room where Lady V. used to sit, that she had a telephone, and finally decided to call upon Major H. himself, before Lady V. telephoned her version of the story to him. Throughout his book, Varendonck indicates certain correlations between the rising and falling of conscious- 70 THE ART OF THOUGHT Ch. 3 ness and the rising and falling of other elements in the association-process. One such correlation will remind English readers of the description of falling from day dreaming into sleep-dreaming at the beginning of Lewis Carroll’s Alice in Wonderland. As the level of conscious¬ ness sank, he found that the critical power which the civilized human being acquires from education and ex¬ perience sank with it; the steps from one link to another in association often became such as in his fully waking state he would have at once recognized as absurd, and his objections to them might be equally absurd. He describes, for instance, a ‘bombardment’ phantasy, in which his mind assumed that after losing both legs he would be compelled to continue his military service (p. 114), and a ‘flea phantasy,’ in which he hit upon the ex¬ pedient of using a garden roller for killing a flea in the cracks of his bedroom floor. Freud, also, has shown, though with a serious amount of exaggeration, that as consciousness sinks towards sleep the links in the train of association may become more instinctive and animal; and the vague and generalized tendencies which the writers of his school call ‘sex’ or ‘libido’ may appear in symbolic forms. A similar correlation, therefore, takes place, according to Varendonck, between increas¬ ing consciousness and increasing rationality: ‘The upward movements have for consequence the introduc¬ tion into the concatenations of elements proper to con¬ scious thought, namely elements of critical thought- activity’ (p. 176). Varendonck is, I think, less successful in indicating THOUGHT BEFORE ART 7i Ch. 3 some further correlations between sinking and rising consciousness and the other elements of the associa¬ tion process. He argues, for instance, that decreasing and increasing consciousness is accompanied by a de¬ crease or increase in the use of words, and by a corres¬ ponding increase or decrease in the use of visual images. ‘At one end of the series my foreconciousness thinks in words with a few [visual] illustrations distributed at random; at the other end this ideation seems to proceed by means of pictorial images with occasional verbal ex¬ pressions’ (p. 61). In a passage in which he speaks of his mind in its less-conscious state as his ‘second self,’ he says that this ‘second self’ ‘operates distinctly by means of optical images, and I have reason to think that most persons share this peculiarity with me’ (p. 57). The facts, however, as to the interrelation of verbal and visual imagery with rising and falling consciousness seem to me, even on Varendonck’s own evidence, much more complicated. In actual sleep-dreams, and in the deeper forms of foreconsciousness, we often use words which, if we happen afterwards to remember them, are found to belong to the type which psychologists call ‘glossolaly,’ and which may be less rational than the most absurd dream-images. 1 At a stage of conscious¬ ness well below rationality, a coherent but almost mean¬ ingless jingle of words may form itself in our minds, and appear to be perfectly satisfactory. Mr. Robert Graves, for instance, describes his delight with a dream- poem consisting of the words: 1 See Varendonck (Day Dreams ), p. 331. 72 THE ART OF THOUGHT Ch. 3 ‘It’s Henry VIII, it’s Henry VIII, He is leading his armies over to France.’ 1 And a relative of mine woke one morning with the con¬ viction that she had achieved immortality by the lines: ‘Leave there thy steed, And let it feed On more than meets the eye.’ And, though it may be true that the use of visual and other ‘images’ plays on the average a larger part (when compared with the use of words) in less conscious than in more conscious thought, some of the most com¬ pletely conscious and most rational thought may be carried on entirely by the use of wordless images. A very able and rapid financial thinker, who was trained as a mathematician, told me that even when his thought is most conscious and rational he thinks, like a chess¬ player, in terms of seen or felt wordless ‘ situations.’ The wordless images of such a ‘situation’ may be purely ‘kinetic,’ with little or no visual element. The chess correspondent of the Observer (Feb. 8, 1925) writes that the great chess-player Alekhin said that ‘he does not see the pieces in his mind, as pictures, but as force- symbols; that is as near as one can put it in words.’ Again, when reading Varendonck, one has always to remember that almost the whole of his first-hand evi¬ dence is derived from introspection during the process of sinking towards, or rising away from sleep, and that 1 On English Poetry (1922), d. 16. THOUGHT BEFORE ART Ch. 3 73 that fact limits the validity of his conclusions about thought carried on under other conditions. He says, for instance, that ‘the chains of thought which occupy our minds during our distractions in waking life are wholly similar to the phantasies that arise in the somno¬ lent state’ (p. 34). He illustrates this by a description of the process in which thoughts and counter-thoughts arise in our mind and are accepted and rejected when we are in a state of ‘full awareness.’ If, for instance, one has to compose and send a painful letter: ‘One thinks about the letter; and in one’s mind it has already been composed over and over again before one writes it down; every argument that one can think of has been put forward and criticized, dropped or retained, until in the end the letter is present in the mind before it is confided to paper’ (p. 139). In a later book, Varen- donck points out that ‘the orator prepares his speech in the same way, while his mind is absent during a purely physical occupation; the business-man unintentionally ponders over his affairs in the train, or as he walks to the office; the journalist has his article in his mind be¬ fore reaching his office.’ 1 I myself, however, believe that though less-conscious thought during our hours of full wakefulness has many analogies with the less-con¬ scious thought which occurs while the main nervous system is sinking into natural sleep or the hypnotic trance, there is a difference between the two pro¬ cesses, which is of great importance in the higher and more difficult forms of intellectual creation (see below, 1 Varendonck, Evolution of the Conscious Faculties (1923), p. 108, 74 THE ART OF THOUGHT Ch. 3 chapter IX). And the process of ‘distraction’ in waking life, when a fully-conscious train of association is broken in upon by a call for our attention to another subject, is different from the process in which Alice in Won¬ derland ceased to think about cats and bats, and sank into a region where it seemed quite natural that a white rabbit should carry a watch in his waistcoat pocket. Finally, the student who desires to use Varendonck’s evidence as a working description of ‘natural’ thought, must remember that Varendonck was originally attracted to the whole question by reading Freud’s In¬ terpretation of Dreams ; and that although he is obviously a man of high intellectual integrity, and much less liable to the involuntary distortion of his introspective observations by loyalty to his master than are most of the followers of Freud, yet even he seems to feel bound to ascribe every train of association to the driving force of some ‘wish’ or ‘instinct’ or ‘affect.’ He uses, indeed, the term ‘affective thinking’ as synonymous with ‘fore¬ conscious thinking’ (e.g. p. 19). He can do so with less violence to the facts, because the ‘day-dreams’ which he describes are almost all the result of intense anxiety either as to his position in the army, or his professional future, or his intended re-marriage. But nevertheless in conscientiously analysing his thought-trains he has to use the word ‘affect’ in many different senses, and sometimes, apparently, in hardly any sense at all. He says, indeed, frankly, that ‘I am quite aware that this same word affect has been used in my various arguments Ch. 3 THOUGHT BEFORE ART 75 to denote very different notions, such as wishes, emotions, etc.’ (p. 245). 1 One has to be similarly on one’s guard in using the description of his thought-processes given by H. Poin - carej n the celebrated chapter on ‘Mathematical Inven¬ tion’ in his Science and Method, (translated 1914). Poin¬ care is also dealing with the complicated and still insufficiently analysed problem of ‘emotion’ as a fre¬ quent directing force in the association process, and as a still more frequent accompaniment of that process. And he, too, under the influence of the general ten¬ dency in psychological theory which I have called the ‘mechanist’ view, simplifies that relation by ascribing the direction of all association trains to the drive of some instinctive emotion. He asks what is the selective force , t he ‘sieve.’ which chooses t h e appare ntly_right solution of a mathematical problem and brings it into full con- s ciousness, while refecting the apparently wrong solu¬ tion. He answers tha t the c ause is ‘sensibilite’ — an ex- tremely ambiguous French term which may either be translated ‘feeling’ or merely anglicized as ‘sensibility.’ ‘More commonly,’ he says, ‘the privileged unconscious phenomena, those that are capable of becoming con¬ scious, are those which, directly or indirectly, most deeply affect our sensibility’ (p. 58). He adds that, in 1 Varendonck’s later book, The Evolution of the Conscious Faculties (1923), is much less valuable than his Day Dreams (1921), because it contains fewer of those introspective records in which he excels, and more of the psychological generalisations in which he seems to me to be weak. 76 THE ART OF THOUGHT Ch. 3 the case of his own mathematical discoveries, the sensi¬ bility concerned is that which arises from the aesthetic instinct. ‘It may appear surprising that sensibility should be introduced in connection with mathematical demonstrations, which, it would seem, can only interest the intellect. But not if we bear in mind the feeling of mathematical beauty, of the harmony of numbers an d forms, and of geometric elegance. It is a real aesthetic feeling, that all true mathematicians recognize. . . . The useful combinations are precisely the most beauti- ful’ (p. 58). Poincare’s authority is sufficient to assure us that in his case the instinctive appreciation of elegance did play a real part in stimulating and guiding many of his sub¬ conscious trains of thought, and in deciding which of many subconsciously imagined solutions should pro¬ duce t he ‘click’ of cons cious succes s. He may even be right in saying that without a rather high degree of this testhetic instinct no man will ever be a great mathe¬ matical discoverer (p. 60). But it is extremely unlikely that the aesthetic instinct alone was the ‘power’ driving the ‘machine’ of his thought. He must have possessed some of that ‘public spirit’ which is an almost indispen- able condition of a lifetime spent in intellectual toil. He must have had many ambitions and loyalties and habits of thinking and feeling. Above all he had a brain which without scope for its self-activity would have been as restless as a wild hawk in a cage. And each of these factors must have played its part in the thought- processes that went on in the varying levels of his con- Ch. 3 THOUGHT BEFORE ART 77 sciousness. One almost fears that if Poincare had been a friend of Freud, instead of being a friend of Boutroux who was a friend of William James, he might have be¬ come certain that libido was the sole and sufficient ‘sieve’ of his thoughts. But, while the introspective evidence both of Varen- donck and of Poincare is, I believe, presented in a set¬ ting of over-simplified theory, it is nevertheless possible for the student after reading their books to form, with the help of his own introspection, a fair working con¬ ception of t hose ‘natural’ th ought-processes, which, however much influenced by experience and habit, arc not, at the time of thinking, voluntarily controlled by any rules of the thinking a rt. He will observe in his own mind automatic trains of associated ideas, some ending with a remembered positive or negative decision, some broken and at once forgotten. Some of these trains may belong to that primitive type which has given rise to the ‘mechanist’ conception of the relation be¬ tween ‘instinct’ and ‘reason.’ That is to say, behind the train may be the urge of a strong and simple instinct, love, or hatred, or fear, driving the train onward, judg¬ ing its results, and bringing it back again and again to the same starting-point. Or the connecting cause may be some habit of thought; or, again, the upper brain may be actirg on its own initiative, or in obedience to a ‘curiosity’ which may only be another name for more or less independent brain-activity. And, at any moment, a passionless association may lead him to a conclusion that wakens a vehement passion, or a train of thought 7$ THE ART OF THOUGHT Ch. 3 driven by passion may fade into a passionless reverie. Flickering over all these processes, as the searchlights flicker along a line of cliffs, there may be a hundred different conscious or less-conscious ‘feelings,’ alterna-* ting with, and fading into each other. He may be dimly aware of some brooding ‘sentiment.’ The hor¬ mones discharged by the obscure processes of the endo¬ crine glands may pervade him with v ague ‘euphoria’ or ‘dysphoria’ — e lation or discomfor t, energy or inertia. Actual sensations, and the more or less vivid memories of sensations, may play their part. Or, he may be able afterwards to remember sudden flashes of emotional experience almost too momentary for description, feel¬ ings of queerness, or surprise, or recognition, or amuse¬ ment, or the craftsman’s delight in his own skill and success. IV STAGES OF CONTROL So far, in this book. I have discussed two pr oblems which are preliminary to any formulation of an art of t houg ht: first, wh at conception of the human or ganism and human consciousness best indicates the general facts with which such an art must deal; and,, secondly, what is the ‘natural’ thought-proccssjwhich such an art must attempt to modify. In this chapter, I shall ask at what stages in that thought-process the thinker > should bring the conscious and voluntary effort of his art_to_h,ear. Here we at once meet the difficulty that unless we can recognize a psychological event, and dis¬ tinguish it from other events, we cannot bring con¬ scious effort to bear directly upon it; and that our mental life is a stream of intermingled psychological events, all of which affect each other, any of which, at any given moment, may be beginning or continuing or ending, and which, therefore, are extremely hard to distinguish from each other. We can, to some degree, avoid this difficulty if we t ake a sing l e achievement o f thought — the making of a new generalization or inven tion, or the poetical ex¬ pression of a new idea — a nd ask how it was brou g ht about . We can then rou ghly d issect out a continu ous J process, with a beginning and a middle and an en d of! its own. Helmholtz, for insta nce, the great German' physicist, speaking in 1891 at a banquet on his 79 8o THE ART OF THOUGHT Ch. 4 -fjCoA . seventieth birthday, described the way in which his most important new thoughts had come to him. He said that after previous investigation of the problem ‘in all directions . . . happy ideas come unexpectedly without effort, like an inspiration. So far as I am con¬ cerned, they have never come to me when my m ind was fatigued, or when I was at my working table. . . . They came particularly readily during the slow ascent of wooded hills on a sunny day.’ 1 Helmholtz here gives us three stages in the formation of a new thought. The first in time I shall call Preparation, the stage du rmg which the problem was ‘investigated ... in all direcr t ions’ ; the second is the stage during which he was not consciously thfnkTng about the problem, which I shall call Incubation^ the third, consi sting of th e appear an ce of the ‘happy idea’ together with the psychological events which immediately preceded and accompanied that appearance, I shall call Illuminatio n. A nd I shall add a fourth sta ge, of Verification ? which Helmholtz does not here mention. Henri Poincare, for instance, in the book Science and Method , which I have already quoted (p. 75), describes in vivid detail the successive stages of two of his great mathematical dis- 1 See Rignano, Psychology of Reasoning (1923), pp. 267-8. See also Plato, Symposium (210): ‘He who has been instructed thus far in the things of love, and has learned to see beautiful things in due order and succession, when he comes to the end, will suddenly perceive a beauty wonderful in its nature’; and Remy de Goncourt: ‘My conceptions rise into the field of consciousness like a flash of lightning or the flight of a bird’ (quoted by H. A. Bruce, Psychology and Parenthood, 1919, p. 89). 8 r Ch. 4 STAGES OF CONTROL coveries. Both of them came to him after a period of Incubation (due in one case to his military service as a reservist, and in the other case to a journey), during which no conscious mathematical thinking was done, but, as Poincare believed, much unconscious mental exploration took place. In both case s Incu bation was preceded by a Preparation stage of hard, conscious. P systematic, and fruitless analysis of the prob lem. In both cases the final idea came to him ‘with the same characteristics of conciseness, suddenness, and im¬ mediate certainty* (p. 54). Each was followed by a period of Verification, in which both the validity of the idea was tested, and the idea itself was reduced to exact form. ‘I t never happens,’ says Poincare, in his descrip¬ tion of the Verification stage, ‘that unconscious work. supplies ready-made^ the res ult of a lengthy calculation in which we have only to apply fixed rules. . . . AE that we can hope from these inspirations, which arc the. fruit of unconscious work, is to obtain poin ts of depar¬ ture for such calculations . As for the calculations them¬ selves, they must be made in the second period of con¬ scious work which follows the inspiration, and in which the results of the inspiration are verified and the conse¬ quences deduced. The rules of these calculations are strict and complicated; they demand discipline, atten¬ tion, will, and consequently, consciousness’ (pp. 62, 63). In the dai ly stream of thought thpsp fopr Hiffpr- ent stages constantly overlap each other as we explore differen t problems. An economist reading a Blue Book, a physiologist watching an experiment, or a business 82 THE ART OF THOUGHT Ch. 4 man going through his morning’s letters, may at the same time be ‘incubating’ on a problem which he pro¬ posed to himself a few days ago, be accumulating know¬ ledge in ‘preparation’ for a second problem, and be ‘verifying’ his conclusions on a third problem. Even in exploring the same problem, the mind may be uncon¬ sciously incubating on one aspect of it, while it is con¬ sciously employed in preparing for or verifying another aspect. And it must always be remembered that much v ery im portant thinking, done for instance by a poet. exploring his own memories*, or by a man trying to see clearly his emotional relation to his country or his party, resembles musical co mposition in that the stages lead- ing to success are not very easily fitted into a ‘probl em and solution’ scheme. Yet, even when success in thought means the creation of something felt to be beautiful and true rather than the solution of a pre¬ scribed problem, the four stages of Preparation, Incu¬ bation, Illumination, and the Verification of the final result can generally be distinguished from each other. If we accept this analysis, we are in a position to ask t o what de gree, an d b y what m eans, we can bring con¬ scious effort, and the habits w'hich arise from conscious effort, to bear upon each of the f our stages. I shall not* in this chapter, deal at any length w r ith the stage of Pre¬ paration. It includes the whole process of intellectual educatio n. Men have known for thousands of years that conscious effort and its resulting habits can be used to improve the thought-processes of young persons, and have formulated for that purpose an elaborate art of STAGES OF CONTROL Ch. 4 83 education. The ‘educated’ man can, in consequence, ‘ put his mind on’ to a chosen subject, and ‘turn his mind off’ 1 in a wav which i s impossible to an unedu¬ cated man.. The educated man has also acquired, by the effort of observation and memorizing, a body of remembered facts and words which gives him a wider range in the final moment of association, as well as a number of those habitual tracks of association which constitute ‘thought-systems’ like ‘French policy’ or ‘scholastic philosophy’ or ‘biological evolution,’ and which present themselves as units in the process of thought. The educated man has, again, learnt, and can, in the Preparation stage, voluntarily or habitually follow ou t. rules as to the order in which he shall direct his atten - tion to the successive elements in a problem. Hobbes referred to this fact when in the Leviathan he described ‘regulated thought,’ and contrasted it with that ‘wild ranging of the mind’ which occurs when the thought process is undirected. Regulated thought is, he says, a ‘seeking.’ ‘Sometimes,’ for instance, ‘a man seeks what he has lost. . . . Sometimes a man knows a place deter¬ minate, within the compass whereof he is to seek; and then his thoughts run over all the parts thereof, in the same manner as one would sweep a room to find a jewel; or as a spaniel ranges the field, till he find a scent; or as a man should run over the alphabet, to start a rhyme.’ A spaniel with the brain of an educated human being could not, by a direct effort of will, scent a partridge in a 1 See Sir H. Taylor in my Our Social Heritage, Chap. II. 84 TH E ART OF THOUGHT Ch.4 distant part of the field. But he could so ‘quarter’ the field by a preliminary voluntary arrangement that the less-voluntary process of smelling would be given every chance of successfully taking place. I ncluded in these rules for th e pr eliminary ‘regula ¬ tion’ of our thought are the whole traditional art of logic, the mathematical forms which are the logic of the modern experimental sciences, and the methods of systematic and continuous examination of present or recorded phenomena which are the basis of astronomy, sociology and the other ‘observational’ sciences. Closely connected with this voluntary use of logical methods is the voluntary choice of a ‘problem-attitude’ (Auf- gabe). Our mind is not likely to give us a clear answer to any particular problem unless we set it a clear ques^. tion, and we are more likely to notice the significance of any new piece of evidence, or new association of ideas, if we have formed a definite conception of a case to be proved or disproved. A very successful thinker ' in natural science told me that he owed much of his success to his practice of following up, when he felt his mind confused, the implications of two propositions, both of which he had hitherto accepted as true, until he had discovered that one of them must be untrue. Huxley o n that point once quoted B acon, ‘ Tru th comes out of error much more rapidly than it co mes__out of c onfusion? and went on, ‘If you go buzzing about between right and wrong, vibrating and fluctuating, you come out nowhere; but if you are absolutely and thoroughly and persistently wrong you must some_of STAGES OF CONTROL Ch. 4 85 these days have the extreme good fortune of knocking, your head against a fact, and that sets you all right again.’ 1 This is, of course, a production, by conscious effort, of that ‘dialogue form’ of alternate suggestion and criticism which Varendonck describes as occurring in the process of uncontrolled thought. 2 It is, indeed, sometimes possible to observe such an automatic ‘dia¬ logue’ at a point where a single effort of will would turn it into a process of preparatory logical statement. On July 18, 1917, I passed on an omnibus the fashionable church of St. Margaret’s, Westminster. Miss Ashley, the richest heiress of the season, was being gorgeously married, and the omnibus conductor said to a friend, ‘Shocking waste of money! But, there, it does create a lot of labour, I admit that.’ Perhaps I neglected my duty as a citizen in that I did not say to him, ‘Now make one effort to realize that inconsistency, and you will have prepared yourself to become an economist.’ And though I have assumed, for the sake of clear¬ ness, that the thinker is preparing himself for the solu¬ tion of a single problem, he will often (particularly if he is working on the very complex material of the social sciences) have several kindred problems in his mind, on all of which the voluntary work of preparation has been, or is being done, and for any of which, at the Illumination stage, a solution may present itself. The fourth stage, of Verification, closely resembles 1 ‘Science and Art and Education,’ Huxley, Collected Essays, Vol, III, p. 174. 2 See above, p. 68, 86 THE ART OF THOUGHT Ch. 4 o t he first stage, of Preparatio n. It is normally, as Poin¬ care points out, fully conscious, and men have worked out much the same series of mathematical and logical rules for controlling Verification by conscious .effort as those which are used in the control of Preparation. There remain the second and third stages, Incuba¬ tion and Illumination. The Incubation stage covers two different things, of which the first is the negative fact that during Incubation we do not voluntarily_pr consciously think on a particular problem, and the second.is the positive fact that a series of unconscious and involuntary (or foreconscious and forevoluntary) mental events may take place during that period. It js the first fact about Incubation which I shall now dis¬ cuss, leaving the second fact — of subconscious thought during Incubation, and the relation of such thought to Illumination - to be more fully discussed in connection with the Illumination stage. Voluntary abstention from conscious thought on any particular problem may, itself, take two forms: the period of abstention may be spent either in conscious m ental work on other problems, or in a relaxation from all conscious mental work. The first kind of Incubation economizes time, and is there¬ fore often the better. We can often get more result in the same time by beginning several problems in suc¬ cession, and voluntarily leaving them unfinished while we turn to others, than by finishing our work on each problem at one sitting. A well-known academic p sychologist, for instance, who was also a preacher, t old me that he found by experience that his Sunday sermon Ch. 4 STAGES OF CONTROL 87 was much better if he posed the problem on Monday than if he did so later in the week, although he might give the same number of hours of conscious work to it in each case. It seems to be a tradition among practis¬ ing barristers to put off any consideration of each brief to the latest possible moment before they have to deal with it, and to forget the whole matter as rapidly as possible after dealing with it. This fact may help to explain a certain want of depth which has often been noticed in the typical lawyer-statesman, and which may be due to his conscious thought not being sufficiently extended and enriched by subconscious thought. But, in the case of the more_.difficult forms of crea- Go ■ five thought, the making, for instance, of a scientific discovery, or the writing of a poem or play or the formulation of an important political decision, it is desirable not only that there should be an interval free from conscious thought on the particular problem con¬ cerned, but also that that interval should be so spent that nothing should interfere with the free working of the unconscious or partially conscious processes of the mind.^ In those cases, th e stage of Incubation sh ould- i n elude a large amount of actual mental relaxa tion. It would, indeed, be interesting to examine, from that point of view, the biographies of a couple of hundred original thinkers and writers. A. R. Wallace, for in¬ stance, hit upon the theory of evolution by natural selection in his berth during an attack of malarial fever at sea; and Darwin was comp elled by ill-health to spend the greater part of his waking hours in physical and 88 THE ART OF THOUGHT Ch.4 mental relaxation. S ometimes a thinker has been able to get a sufficiency of relaxation owing to a disposition to idleness* against which he has vainly struggled. More often, perhaps, what he has thought to be idle¬ ness, is really that urgent craving for intense and uninterrupted day-dreaming which Anthony Trollope describes in his account of his boyhood. One effect of such a comparative biographical study might be the formulat ion nf .a__frw f 0 thr relation between original intellectua l work a nd the virtue of indu stry. There ar e thousands of idle ‘ geniuses ’ who require to learn that, without a degre e of industry in Preparation and Verification, of which many of them have nox onceptian. no great inte llectual work can be done, and that the h abit of procrastination may be even more disastrous to a pr ofessiona l thinker than it is to a man of business . And yet a thinker of good health and naturally fertile mind may have to be told that mere industry is for him, as it was for Trollope in his later years, the worst temptation of the devil. Cardinal Manning was a man of furious industry, and the suspension of his industry as an Anglican arch¬ deacon during his illness in 1847 was, for good or evil, an important event in the history of English religion. Some of those who, like myself, live in the diocese of London, believe that we have reason to regret an in¬ sufficiency of intellectual leadership from our present bishop. The bishop himself indicated one of the causes of our discontent in a letter addressed, in September, 1922, to his clergy. ‘I come back to an Ch. 4 STAGES OF CONTROL 89 autumn of what, from a human point of view, is un¬ relieved toil. October 1st to Christmas Day is filled every day, except for the one day off every week, from 10 a.m. to 6 p.m.’ Then comes a long list of adminis¬ trative and pastoral engagements, including ‘three days interviewing no Harrow boys to be confirmed,’ ‘a critical Bill to see through the House of Lords,’ and ‘some sixty sermons and addresses already arranged in the diocese, besides the daily letters and interviews.’ ‘All this,’ he says, ‘might justify the comment of a kindly man of the world, “Why, Bishop, you live the life of a dog! But this is precisely, though on a larger scale, the life of every one of you.’ ’ ’ x It is clear that the bishop considers that he and his clergy ought to be admired for so spending their time; and that he con¬ ceives the life of a turnspit dog to be the most likely to enable them to be successful in the exercise of their office. One sometimes, however, wonders what would be the result if our bishop were kept for ten weeks in bed and in silence, by an illness neither painful nor dangerous, nor inconsistent with full mental efficiency. Mental relaxation during the Incubation stage may. of course include, and sometimes requires, a certain amount of p hysical exercise. I have already quoted Helmholtz’s reference to ‘ the ascent of wooded hills on a sunny day.’ A. Carrel, the great New York physiologist, is said to receive all his really important thoughts while quietly walking during the summer 1 Qhurch Times, Sept. 22, 1922, 90 THE ART OF THOUGHT Ch.4 vacation in his native Brittany. Jastrow s ays that ‘t hinkers have at all times resorted to the restful in ¬ s piration of a walk in the woods or a stroll over hill ;::id dale.’ 1 When I once discussed this fact with an athletic Cambridge friend, he expressed his gratitude for any evidence which v/ould prove that it was the duty of all intellectual workers to spend their vacations in Alpine climbing. Alpine climbing has undoubtedly much to give both to health and to imagination, but it would be an interesting quantitative problem whether Goethe, while riding a mule over the Gemmi Pass, and Wordsworth, while walking over the Simplon, were in a more or in a less fruitful condition of Incubation than are a modern Alpine Club party ascending, with hands and feet and rope and ice-axe, the Finster- Aarhorn. In this, however, as in many other respects, it may be that the human organism gains more from the alternation of various forms of activity than from a consistent devotion to one form. In England, the ad¬ ministrative methods of the older universities during term-time may, I sometimes fear, by destroying the possibility of Incubation, go far to balance any intel¬ lectual advantages over the newer universities which they may derive from their much longer vacations. At Oxford and Cambridge, men on whose powers of in¬ vention and stimulus the intellectual future of the country may largely depend, are made personally re¬ sponsible for innumerable worrying details of filling up forms and sending in applications. Their subconscious 1 J* Jastrow, The Subconscious (1906), p. 94. Ch. 4 STAGES OF CONTROL 91 minds are set on the duty of striking like a clock at the instant when Mr. Jones’s fee must be paid to the Registrar. In the newer English universities, the same duties are rapidly and efficiently performed by a corps of young ladies, with card-catalogues, typewriters, and diaries. But perhaps the most dangerous subs_titUte_for bodily a nd mental relaxation during the stag e of Incubation is ^ neither violent exercise nor r outine administration , but the habit of industrious passive reading. Schopenhauer wrote that ‘to put away one ’s own original thoughts m ) order to take up a book is the sin against the Holy Ghost ,’ 1 During the century from 1760 to x 860, many/ of the best brains in England were prevented from acting with full efficiency by the way in which the Greek and Latin classics were then read. It is true that Shelley’s imagination was stung into activity by Plato and iEschylus, and that Keats won a new vision of life from Chapman’s translation of Homer; but even the ablest of those who then accepted the educational ideals of Harrow and Eton and Oxford and Cambridge did not approach the classical writers with Shelley’s or Keats’s hunger in their souls. They plodded through Horace and Sophocles and Virgil and Demosthenes with a mild conscious aesthetic feeling, and with a stronger and less conscious feeling of social, intellectual and moral superiority; a nyone who was in the habit of r eading the classi cs with his feet on the fender must 1 Schopenhauer, ‘Selbstdenkcn,’ § 260, Parerga und Paralipometia (1851), Vol. II, p. 412. 92 THE ART OF THOUGHT Ch.4 certainly, they felt, be not only a gentleman and a scholar but also a good man. Carlyle once told Anthony Trollope that a man, when travelling, ‘should not read, but sit still and label his thoughts/ 1 On the other hand, Macaulay, before he went out to India in 1834 to be Legislative Member of the Supreme Council, wrote to his sister: ‘The provision which I design for the voyage is Richardson, Voltaire’s works, Gibbon, Sismondi’s History of the French , Davila, Orlando in Italian, Don Quixote in Spanish, Homer in Greek, Horace in Latin. I must also have some books of jurisprudence, and some to initiate me in Persian and Hindustanee’; and, at the end of the four months’ voyage, he wrote: ‘Except at meals, I hardly exchanged a word with any human being. . . . During the whole voyage I read with keen and increasing enjoyment. I devoured Greek, Latin, Spanish, Italian, French, and English; folios, quartos, octavos, and duodecimos.’ 2 If he had followed Carlyle’s advice, he would have had a better chance of thinking out a juristic and educational policy for India which would not have been a mere copy of an English model. One understands why Gladstone’s magnificent enthusiasm and driving force was never guided by sufficient elasticity or originality of mind, when one reads, in Mrs. Gladstone’s Life , how she and her sister married the two most splendid Etonians of their time - Gladstone and his friend Lord 1 Trollope’s Autobiography (edition of 1921), p. 94. 2 G. O. Trevelyan, Life of Macaulay (edition of 1881), pp. 256 and 262, Ch. 4 STAGES OF CONTROL 93 Lyttelton - and spent a honeymoon of four in Scotland. ‘Any little waiting time as at the railway station,’ says her daughter, Mrs. Drew, ‘was now spent in reading — both husbands carrying the inevitable little classics in their pockets.’ During the days when new knowledge, new forms of thought, new methods in industry and war and politics, and the rise of new nations were trans¬ forming Western civilization, ‘Lord Lyttelton was to be seen at cricket-matches in the playing field at Eton, lying on his front, reading between the overs, but never missing a ball.’ 1 So far in this chapter I have inquired how far we can voluntarily improve our methods of thought at those stages — Preparation, Incubation (in its negative sense of abstention from voluntary thought on a particular problem), and Verification - over which our conscious will has comparatively full control. I sh all no w.discuss, the much more difficult question of the degree to which, our will can influence the less controllable stage which. I have called Illumination . Helmholtz and Poincare, in the passages which I quoted above, both speak of the appearance of a new idea as instantaneous and un¬ expected. If we so define the Illumination stage as to re strict it to this instantaneous ‘flash ,’ it is obviou s that we cannot influence it by a direct effort of will; because we can only bring our will to bear upon psychological events which last for an appreciable time. On the other hand, the final ‘flash,’ or ‘click’, as I pointed out in Chapter III, is the culmination of a successful train of 1 Catherine Gladstone , by Mary Drew, p. 32. 94 THE ART OF THOUGHT Ch. 4 association, which may have lasted for an appreciable t ime, and which has p robably been preceded by a series of tentative and unsuccessful trains. The series of unsuccessful trains of association may last for periods varying from a few seconds to several hours. H. Poincare, who describes the tentative and unsuc¬ cessful trains as being, in his case, almost entirely unconscious, believed that they occupied a considerable proportion of the Incubation stage. ‘We might,' he wrote, ‘say that the conscious work, [i.e., what I have called the Preparation stage], proved more fruitful because it was interrupted [by the Incubation stage], and that the rest restored freshness to the mind. But it is more probable that the rest was occupied with unconscious work, and that the result of this work was afterwards revealed.' 1 Different thinkers, and the same thinkers at different t imes, must, of course, v ary greatly as to the time occu¬ pied by their unsuccessful trains of associatipn; and the same variation must exist in the duration of the final and successful train of association. Sometimes the suc¬ cessful train seems to consist of a single leap of associa¬ tion, or of successive leaps which are so rapid as to be 1 H. Poincare, Science a?id Method (trans., pp. 54 and 55). On the other hand, one of the ablest of modern mathematical thinkers told me that he believed that his Incubation period was, as a rule, spent in a state ofactuaLmcntalxQpQ.se for a lLorpartof his bra in, which made the l ater explosi on of intense a nd successful thought possi ble. His belief may have been partly due to the fact that his brain started fewer unsuc¬ cessful and more successful association-trains than the brains of other men. STAGES OF CONTROL Ch. 4 95 almost instantaneous. Hobbes’s ‘Roman penny’ train of association occurred between two remarks in an ordinary conversation, and Hobbes, as I have said, ends his description of it with the words, ‘and all this in a moment of time, for thought is quick’ ( Leviathan , Chap. III). Hobbes himself was probably an excep¬ tionally rapid thinker, and Aubrey may have been quot¬ ing Hobbes’s own phrase when he says that Hobbes used to take out his no te-book ‘as soon .as a thought darted,.’ 1 But if our will is to control a psychological process, it is necessary that that process should not only last for an appreciable time, but should also be, during that time, sufficiently conscious for the thinker to be at least av/are that something is happening to him. On this point, the evidence seems to show that both the success¬ ful trains of associat ion, which might have led to the ‘flash’ of success, and the final and successful train are normally either unconscious, or take place (with ‘ris¬ ings’ and ‘fallings’ of consciousness as success seems to approach or retire), in that periphery or ‘fringelof con- sciousness_which surrounds our ‘focal’ consciousness as the sun’s ‘corona’ surrounds the disk of full luminosity. 2 1 See my The Great Society, (1914), p. 201. 2 I take the word ‘fringe’ from William James, who says in his Prin¬ ciples, Vol. I, p. 2 5 8: ‘Let us use the words psychic overtone, suffusion, or fringe, to designate the influence of a faint brain process upon our thought, as it makes it aware of relations and objects but dimly per¬ ceived.’ The characteristics of our ‘fringe-consciousness’ may be a result of that ‘hormic’ character of the human organism which I dis¬ cussed in Chapter I. The ‘over’ and ‘under’ tones of a piano indicate 96 THE ART OF THOUGHT Ch.4 This ‘fringe-consciousness’ may last up to the ‘flash’ instant, may accompany it, and in some cases may con¬ tinue beyond it. But, just as it is very difficult to see the sun’s corona unless the disk is hidden by a total eclipse, so it is very difficult to observe our ‘fringe-conscious¬ ness’ at the instant of full Illumination, or to remember the preceding ‘fringe’ after full Illumination has taken place. As William James says, ‘When the conclusion is there, we have always forgotten most of the steps pre¬ ceding its attainment’ (.Principles , Volume I, p. 260). It is obvious that both Helmholtz and Poincare had either not noticed, or had forgotten any ‘fringe-con¬ scious’ psychological events which may have preceded and have been connected with the ‘sudden’ and ‘un¬ expected’ appearance of their new ideas. But other thinkers have observed and afterwards remembered their ‘fringe-conscious’ experiences both before and even at the moment of full Illumination. William James himself, in that beautiful and touching, though sometimes confused introspective account of his own thinking which forms Chapter IXof h\sPrinciples, says: ‘Every definite image in the mind is steeped and dyed in the free water that flows round it. With it goes the sense of its relations, near and remote, the dying echo of whence it came to us, the dawning sense of whither the simultaneous vibration ot other strings under the influence of the string which was originally struck. The ‘fringe-consciousness’ of a human being may sometimes indicate that the activity of the main centre of his consciousness is being accompanied by the imperfectly co-ordinated activity of other factors in his organism. Ch. 4 STAGES OF CONTROL 97 it is to lead. The significance, the value, of the image is all in this halo or penumbra that surrounds and escorts it’ ( Principles , Vol. I, p. 255). I find it convenient to use the te rm ‘ Intimation * for t hat moment in the Illumination stage when our fringe- consciousness of an association-train is in the state of rising consciousness which indicates that the fully con¬ scious flash of success is coming. A high English civil servant described his experience of Intimation to me by saying that when he is working at a difficult problem, ‘I often know that the solution is coming, though I don’t know what the solution will be,’ and a very able university student gave me a description of the same fact in his case almost in the same words. Many thinkers, indeed, would recognize the experience which Varendonck describes when he says that on one occa¬ sion : ‘When I became aware that my mind was sim¬ mering over something, I had a dim feeling which it is very difficult to describe; it was like a vague impression of mental activity. But when the association had risen to the surface, it expanded into an impression of joy.’ 1 His phrase ‘expanded into an impression of joy/ clearly describes the rising of consciousness as the flash approaches. Most introspective observers speak, as I have done, of Intimation as a ‘feeling,’ and the ambiguity of that word creates its usual crop of difficulties. It is often hard to discover in descriptions of Intimation whether the observer is describing a bare awareness of mental 1 The Psychology of Day Dreams , p. 282. G 98 THE ART OF THOUGHT Ch.4 activity with no emotional colouring, or an awareness of mental activity coloured by an emotion which may either have originally helped to stimulate the train of thought, or may have been stimulated by the train of thought during its course. Mr. F. M . McMurry seems to refer to little more than awareness when he says, in his useful text-book, How to Study (p. 278), ‘Many of the best thoughts, probably most of them, do not come, like a flash, fully into being but find their beginnings in dim feelings, faint intuitions that need to be encouraged and coaxed before they can be surely felt and defined.’ Dewey , on the other hand, is obviously describing awareness coloured by emotion when he says that a problem may present itself ‘as a more or less vague feel¬ ing of the unexpected, of something queer, strange, funny, or disconcerting.’ 1 Wundt was more ambiguous when he said (in perhaps the earliest description of In¬ timation) that feeling is the pioneer of knowledge, and that a novel thought may come to consciousness first of all in the form of a feeling. 2 My own students ha ve desc ribed the Intimation preceding a new thought a s being sometimes coloured by a slight feeling of discom- f ort arising from a sense of separation from one’s accus- tqmed self. A student, for instance, told me that his first recognition that he was reaching a new political 1 How zve think (1910), p. 74. 2 Wundt (quoted by E. B. Titchener, Experimental Psychology of the Thought-Processes, p. 103). Wundt’s words are ‘In diesem Sinn ist das Gefuhl der Pionier der Erkenntniss’ ( Grundzlige der Physio- logischen Psychologic, Vol. II, 1893, p. 521). STAGES OF CONTROL Ch. 4 99 outlook came from a feeling, when, in answer to a ques¬ tion, he was stating his habitual political opinions, that he ‘was listening to himself.’ I can just remember that a good many years ago, in a period prece di ng an impor¬ tant change of my own political position, I had a vague. a lmost physical, recurrent feeling as if my cloth es did not quite fit me. If this feeling of Intimation lasts for an appreciable time, and is either sufficiently conscious, or can by an effort of attention be made sufficiently conscious, it is obvious that our will can be brought directly to bear on it. We can at least attempt to in¬ hibit, or prolong, or divert, the brain-activity which Intimation shows to be going on. And, if Intimation accompanies a rising train of association which the brain accepts, so to speak, as plausible, but would not, without the effort of attention, automatically push to the flash of conscious success, we can attempt to hold on to such a train on the chance that it may succeed. It is a more difficult and more important question whether such an exercise of will is likely to improve our thinking. Many people would argue that any attempt to control the thought-process at this point will always do more harm than good. A schoolboy sitting down to do an algebra sum, a civil servant composing a minute, Shakespeare re-writing a speech in an old play, will, they would say, gain no more by interfering with the ideas whose coming is vaguely indicated to them, be¬ fore they come, than would a child by digging up a sprouting bean, or a hungry man in front of a good meal, by bringing his will to bear on the intimations of 100 THE ART OF THOUGHT Ch.4 activity in his stomach or his salivary glands. A born runner, they would say, achieves a much more success¬ ful co-ordination of those physiological and psycho¬ logical factors in his organism which are concerned in running, by concentrating his will on his purpose of catching the man in front of him, than by troubling about the factors themselves. And a born orator will use better gestures if, as he speaks, he is conscious of his audience than if he is conscious of his hands. This objection might be fatal to the whole conception of an art of thought if it did not neglect two fac ts, first tha t we are not all ‘born’ runners or orators or th inkers, and that a good deal of the necessary work of the world has to be done by men who in such respects have to achieve ski]] instead of receiving it at birth; and, s econdl y, that t he process of learning an art should, even in the c qpe of those who have the finest natural endowment for it . be more conscious than its practic e. Mr. Harry Var- don, when he is acquiring a new grip, is wise to make himself more conscious of the relation between his will and his wrists than when he is addressing himself to his approach-shot at the decisive hole of a championship. The violinist with the most magnificent natural tem¬ perament has to think of his fingers when he is acquir¬ ing a new way of bowing; though on the concert-plat- form that acquirement may sink beneath the level of full consciousness. And, since the use of our upper brain for the discovery of new truth depends on more recent and less perfect evolutionary factors than does the use of our wrists for hitting small objects with a Ch. 4 STAGES OF CONTROL ioi stick, or for causing catgut to vibrate in emotional patterns, conscious art may prove to be even more im¬ portant, as compared to spontaneous gift, in thought than in golf or violin-playing. Here, again, individual thinkers, and the same thinker at different times and when engaged on different tasks, must differ greatly. But my general conclusion is that there are few or none among those whose work in life is thought who will not g ain hv directing their attention from time t o time to the feeling of Intimation, and by bring ing t heir will to bear upon the cerebral processes which _i t indicates. On this point the most valuable evidence that 1 know of is that gi ven by the poe ts. P oets hav e, more con¬ stantly than other intellectual workers, t o ‘make us e’ (as Varendonck says) ‘o f foreconscious processes for conscious ends.’ 1 The production of a poem is a psy¬ chological experiment, tried and tested under severer conditions than those of a laboratory, and.the poet is generally able to describe his ‘fringe-consciousness’ during the experiment with a more accurate and sensi¬ tive use of language than is at the command of most laboratory psychologists. Sev eral of the younger living English poets have given admirable descriptions of I ntimatio n, of ten using metaphors derived from o ur e xperience in daily life of a feeling t hat there is some¬ t hing which we have mislaid, and which we cannot find because we have forgotten what it is . Mr. John Drink- water, for instance, says: 1 The Psychology of Day Dreams , p. 152. ioz THE ART OF THOUGHT Ch.4 ‘Haunting the lucidities of life That are my daily beauty, moves a theme Beating along my undiscovered mind.’ 1 And Mr. James Stephens says: ‘I would think until I found Something I can never find, Something lying on the ground In the bottom of my mind.’ 2 Mr. J. Middleton Murry, in his Problem of Style (1922, P- 93 )> points out the psychological truth of Shake¬ speare’s well-known description of the poet’s work: ... ‘as imagination bodies forth The forms of things unknown, the poet’s pen Turns them to shapes and gives to airy nothings A local habitation and a name.’ ‘ Forms of things unknown ’ a nd ‘airy nothing s’ are vivi d descriptions of the first appearance of Intimati on; and ‘ local habitation and a name’ indicates the increasin g verbal clearness of thought as Intimation approach es t he final moment of Illuminati on; and may also indicate that Shakespeare was a much more conscious artist than many of his admirers believe. Some E nglish poets and students of p o etry h ave gi ven descri ptions not only of the feeling of Intimation, but also of the effort of will by which a poet may at- 1 J. Drinkwater, Loyalties, p. 50 (‘The Wood’). 2 Georgian Poetry (1913-15), ‘The Goat Path,’ p. 189. Ch. 4 STAGES OF CONTROL t empt to influence t he me ntal events indicated by Inti¬ mation. and the dangers to the thought itself involved in such an effort. In these metaphors drawn from a boy’s a> hand an elusive fish, or a bird which will da rt off if the effort is made a fraction of a second too soon or too late. Mr. Robert Grave s allows me to quote in full a charm¬ ing little poem, called ‘ A Pinch of Salt,’ in which he expands and plays with this metaphor: ‘When a dream is born in you With a sudden clamorous pain, When you know the dream is true And lovely, with no flaw nor stain, Oh then, be careful, or with sudden clutch You’ll hurt the delicate thing you prize so much. Dreams are like a bird that mocks, Flirting the feathers of his tail When you seize at the salt-box Over the hedge you’ll see him sail. Old birds are neither caught with salt nor chaff; They watch you from the apple bough and laugh. Poet, never chase the dream. Laugh yourself and turn away. Mask your hunger, let it seem Small matter if he come or stay; But when he nestles in your hand at last, Close up your fingers tight and hold him fast.’ 1 1 Georgian Poetry (1916-17), p. 107. i °4 THE ART OF THOUGHT Ch.4 In this respect, the m ost obvious d an ger ag ainst which the thinker has to guard is that the association- train which the feeling of Intimation shows to be going on may either drift away of itself , as most of our dreams and day-dreams do, into mere irrelevance and forget¬ fulness, or may be interrupted by the intrusion of other, trains of association. All thinkers, know the effect of the ringing ot the telephone bell, or the entrance of so me o ne with a practical question which must be answered , during a promising Intimation. Aristophanes, when in the Clouds he makes Socrates complain that his disciple \b y askin g h i m . a.quest i on had ca usedji v aluable tho u g'n t jt o ‘mis carry, ’ was probably quoting some saying of Socrates himself, whose mother was a midwife, and who was fond of that metaphor. If, therefore, the feeling of Intimation presents itself while one is reading, it is best to look up from one’s book and so avoid the danger that the next printed sentence may ‘start a new hare.’ Varendonck describes how, in one of his day-dreams, ‘The idea that manifested itself ran thus: “ There is something going on in my foreconsciousness which must be in direct relation to my subject. I ought to stop reading for a little while , and let it come to the surface .” And, be¬ sides such negative precautions against the interruption of an association-train, it is often necessary to make a conscious positive effort of attention to secure success. Vincent d’lndy, speaking of musical creation, said that he ‘often has on waking, a fugitive glimpse of a musical effect which — like the memory of a dream — needs a 1 Day Dreams, p. 190. (The italics arc Varendonck’s.) STAGES OF CONTROL Ch. 4 105 strong immediate concentration of mind to keep it from vanishing/ 1 But even the effort of attention to a train of association may have the effect of interrupting or hindering it. Schiller is reported by Vischer to have said that when he was fully conscious of creation his imagination did not function ‘with the same freedom as it had done when nobody was looking over my shoulder/ 2 To a modern thinker, however, the main danger of spoiling a train of association occurs in the process of attempting — perhaps before the train is complete — to put its conclusion into the words. Mr. Henr y Hazlitt, in his T hinking as a Scien ce (1916), p. 82, says, ‘ Thoughts of certain kinds are so elusive that to at¬ tempt to articulate them is to scare them away, as a fi sh i s scared by the slightest ripple . When these thoughts are in embryo, even the infinitesimal attention required for talking cannot be spared’; and a writer on Mon¬ taigne in The Times Literary Supplement for January 31, 1924, says, ‘We all indulge in the strange pleasant pro¬ cess called thinking, but when it comes to saying, even to some one opposite, what we think, then how little we are able to convey! The phantom is through the mind and out of the window before we can lay salt on its tail, or slowly sinking and returning to the profound dark¬ ness which it has lit up momentarily with a wandering light/ In the case of a poet, this danger is increased by 1 See Paul Chabanei, Le Subconscient chez les Artistes , etc. (quoted by H. A. Bruce, Psychology and Parenthood , p. 90). 2 Quoted by H. A. Bruce, Psychology and Parenthood (1915), p. 88. 106 THE ART OF THOUGHT Ch.4 the fact that for the poet the finding of expressive words is an integral part of the more or less automatic thought- process indicated by Intimation. The little girl had the making of a poet in her who, being told to be sure of her meaning before she spoke, said, ‘How can I know what I think till I see what I say?’ A modern professed t hinker must, however, sooner or later in the p rocess of thought, make the conscious effort of expression, with all its r isks . A distant ancestor of ours, some Aurig- nacian Shelley, living in the warm spell between two ice ages, may have been content to lie on the hillside, and allow the songs of the birds and the loveliness of the clouds to mingle with his wonder as to the nature of the universe in a delightful uninterrupted stream of rising and falling reverie, enjoyed and forgotten as it passed.
