[Footnote 1: The technique of reflection will be discussed in detail in the chapter on "Science and Scientific Method."]

On the one hand, the gregarious instinct, the desire for rest, native curiosity, and an acquired interest in drama may prompt him strongly to go to the theater. On the other hand, the habits of industry, ambition, self-a.s.sertion, and studying in the evening urge him to stay at home and study.

The first course of action may, for the moment, be immediately attractive and stimulating. But instead of responding to either immediately, the student rehea.r.s.es dramatically the possibilities a.s.sociated with each. On the one hand are the immediate satisfactions of rest, amus.e.m.e.nt, and companionship.

But as further consequences of the impulse to go out to the theater are seen--or, rather, are foreseen--failure in the examination, the loss of a scholarship, pain to one's family or friends, and chagrin at the frustration of one's deepest and most permanent ideals. The second course of action, to stay at home and study, though it is seen to have connected with it certain immediate privations, is foreseen to involve the further consequences of pa.s.sing the examination, keeping one's scholarship, and maintaining certain personal or intellectual standards one has set one's self. Even if the student decides to follow the first course of action to which an immediate impulse has prompted him, his act is different in quality from what it would have been if he had not reflected at all.

The student goes out fully aware of the consequences of what he is doing; he goes _for_ the immediate pleasure and _in spite of_ the possible failure in the examination. The very heart of reflective behavior is thus seen to lie in the fact that present stimuli are reacted to, not for what they are as immediate stimuli, but for what they signify, portend, imply, in the way of consequences or results. And a response made upon reflection is made on the basis of these imaginatively realized consequences.

We connect what we do with the results that flow from the doing, and control our action in the light of that prophetically realized connection.

The process is obviously not always so simple as that described in the above ill.u.s.tration. In the first place, more than two courses of action may suggest themselves. And the consequences of any one of them may be far more complex and far more obscure than any suggested in the above. For an individual to be able to decide a problem on the basis of consequences imaginatively foreseen, it is often necessary to inst.i.tute a very elaborate system of connecting links between an immediately suggested course of action and its not at all obvious results. "Thinking a thing out" involves precisely this introduction of connecting links, or "middle terms," between what is immediately given or suggested and what necessarily, though by no means obviously, follows. This is ill.u.s.trated in the case of any more or less theoretical problem and its solution. To perceive, for example, the connection between atmospheric pressure and the rise of water in a suction pump involves the introduction of connecting links in the form of the general law of gravitation, of which atmospheric pressure is a special case.

But the same is true of practical problems. A young man may be trying to decide whether or not to take a nomination to the training course at West Point. He may be attracted by the four years' training, and highly value the results of it.

He may think, however, that the training involves an obligation to serve in the army; it may mean, for a long time, service in some remote army post. His decision may be determined by this last consideration, which required a series of intermediate "linking" ideas to bring to light.

The technique of scientific or expert thinking is, in large part, concerned with devices for enabling the thinker more securely to trace the obscure and remote connections between actions and their consequences, between causes and effects.

But, whether simple or complex, the essential feature of reflective activity is that it is action performed in the light of consequences foreseen in imagination. Physical stimuli are not responded to immediately with physical action. They are responded to as symbols, signs, or portents; they are taken as symptoms of the results that _would_ follow if they _were_ acted upon. That is, they are, until decision is made, reacted to imaginatively. When an actual response is finally made, it is made on the basis of the results that have been more or less accurately and directly antic.i.p.ated in imagination.

REFLECTION AS THE MODIFIER OF INSTINCT. Reflection is primarily a revealer of consequences. Instead of yielding to the first impulse that occurs to him, the thinking man considers where that impulse, if followed out, will lead. And since man is moved by more than one impulse at a time, reflection traces the consequences of each, and determines action on the basis of the relative satisfactions it can prophesy after careful inquiry into the situation. To reflect is primarily to query a stimulus, to find out what it means in terms of its consequences. The more alert, persistent, and careful this inquiry, the more will instinctive tendencies be checked and modified and adjusted to new situations.

In the discussion of the acquisition of habits, it was pointed out that useful habits may be acquired most rapidly by an a.n.a.lysis of them into their significant features. The speed with which random instinctive actions are modified into a series of useful habitual ones depends intimately upon how clear and detailed is the individual's appreciation of the results to be achieved by one action rather than another. A large part of learning even among humans is doubtless trial and error, random hit-or-miss attempts, until after successive repet.i.tions, a successful response is made and retained. But human learning and habit-formation are so much more various and fruitful than those of animals precisely because human beings can check and modify instinctive responses in the light of consequences which they can foresee. These foreseen consequences are, of course, derived from previous experience; that is, they are "remembered." But reflection short-circuits the process. The more deliberate and reflective the process of learning, the more the individual notes the connections between the things he does and the results he gets, the fewer repet.i.tions will he need in order effectively to modify his instinctive behavior into useful habits. He will antic.i.p.ate results; he will experience them in imagination. He will not need to make every wrong move in paddling a canoe until he finally hits upon the right one. He will not need to alienate all his clients before learning to deal with them successfully.

In any given set of circ.u.mstances he will form the effective habits rapidly. He will calculate, "figure out," find out in advance. To keep one's temper under provocation, to refrain from eating delicious and indigestible foods, to keep at work when one would like to play, and sometimes to play when one is engrossed in work, are familiar instances of how our first impulses become checked, restrained, or modified in the light of the results we have discovered to be a.s.sociated with them.

REFLECTIVE BEHAVIOR MODIFIES HABIT. The same conscious breaking-up of a new type of action into its significant features, the same connection of a given action with a given result which makes the intelligent learner so much more quickly acquire effective new habits than the one who is mechanically drilled, leads also to a continuous criticism of habits, and their discontinuance when they are no longer adequate. Reflection, if it is itself a habit, is the most valuable one of all. It is an important counterpoise to the hardening and fossilization which repeated habitual actions bring about in the nervous system.

In acting reflectively we subject our accustomed ways to deliberate a.n.a.lysis, however immediately persuasive these may have become, and deliberately inst.i.tute new habits in the light of the more desirable consequences they will bring.

Habits come to be regarded not as final or as good in themselves, but as methods of accomplishing good. If they fail to bring genuine satisfaction, reflection can indicate wherein they are inadequate, wherein they may be changed, and whether they should be altogether discarded.

Reflection thus makes conduct conscious; it is not the subst.i.tute for instinct and habit; it is the guide and controller of both. When we act thoughtfully and intelligently, we are doing things not because we have done them that way in the past, or because it is the first response that occurs to us, but because, in the light of a.n.a.lysis, that way will bring about the most desirable results.

THE LIMITS OF REFLECTION AS A MODIFIER OF INSTINCT AND HABIT.

While our impulses and habits may be subjected to the criticism of reflection in the light of the consequences which it can forecast, reflection is itself seriously limited by our original impulses and our acquired habitual ones. On reflection, we may not follow our first impulse, but to act at all is to act on some original or acquired impulse or a combination of them. Which original tendency we shall follow reflection can tell us; it cannot tell us to follow none. In the ill.u.s.tration already used, the student may upon reflection study rather than go out. But the roots of his studying will also lie back in the instincts and habits which are, for better or for worse, his only equipment for action. They will lie back in the tendencies to be curious, to gain the praise of other people and to be a leader among them, in the habits of knowing work thoroughly, of studying in the evening, of maintaining a scholarship average to which he has been accustomed.

Reflection may weigh the relative persuasions of various impulses; it cannot ignore them. We may think in order to attain our desires, and may, through reflection, learn to change them; we cannot abolish them. Whether we are curious about our neighbors' business or about the movements of the stars and the possible reactions of a strange chemical element, depends on our previous training and the extent to which inquiry itself has become a fixed and persistent habit. But in any case we are curious. Whether we fight in street brawls or in campaigns against tuberculosis, we are still, as it were, born fighters.

Similarly, in the case of habit, we may upon reflection discover that our habits of walking, writing, or speech are bad; that we ought not to smoke, or drink, or waste time. We may come, through reflection, to realize with the utmost clarity the advantages to ourselves of acquiring the habits of going to bed early, saving money, keeping our papers in order, and persisting at work amid distractions. But the bad habits and the good are already fixed in our nervous system, and in physiology also possession is nine tenths of the law. We may _intend_ to change, but by taking thought alone we cannot add a cubit to our stature. Reflection can do no more than point the way we should go. For unless the wrong actions are systematically and repeatedly refrained from, and the proper ones made habitual, thinking remains merely an impotent summary of what can be done. Conduct is governed, it must be repeated, by the satisfactions action can bring us, and unless actions are made habitual they will not be performed with satisfaction.

HOW INSTINCTS AND HABITS IMPAIR THE PROCESSES OF REFLECTION.

It is as important as it is paradoxical that thinking is impaired in its efficiency by the instincts and habits in whose service it arises, and whose conflicts and maladjustments it helps to resolve. The situations of conflict or perplexity which provoke thinking are determined by the particular tendencies which, by nature or training, are brought into play in any given situation. If we are committed by tradition or habitual allegiance to a protective tariff, we will be concerned in our thinking with details, what articles need protection and how much do they need; the ultimate desirability of a protective tariff will not be a problem remotely occurring to us. If we are by training committed to capital punishment, we will be concerned, if we think about it at all, with means and methods; we will think about the relative merits of hanging or electrocution; the ultimate justification or desirability of capital punishment will not be a problem or issue for us at all.

Thus, it may be said in a sense that our thinking is determined by what we do not think about as much as by what we do think about. What we take for granted limits the field within which we will inquire or reflect at all. But what we take for granted is, on the whole, settled by our habitual reactions.

And the more settled habitual convictions we have, the narrower becomes the field within which reflection takes place.

Force of habit may leave us blind to many situations genuinely demanding solution. Originality in thinking consists, in part at least, in an ability to see a problem where others, through routine, see none. Apples have fallen on the heads of others than Newton, but a habit-ridden rustic will not be stirred by the falling of an apple to reflection on the problem of falling bodies. The countryman may live all his life serenely oblivious to a thousand problems that would pique the curiosity and reflection of a botanist or geologist. A man may go on for years accepting income on investments earned in very dubious ways without ever pausing to reflect on the sources or the justification of his wealth.[1]

[Footnote 1: According to the traditional anecdote, when Marie Antoinette was told that the people were clamoring because they could not get any bread, the one problem that occurred to her was why they didn't eat cake. From the habits and conditions of life to which she was accustomed, there had never arisen a problem as to how to get food at all; it was merely a problem of what kind of food to eat.]

Instincts and habits, furthermore, limit the field of possible courses of action that suggest themselves. We come, through habit, to be alive only to certain possibilities to the practical exclusion of all others. Thinking becomes fruitful and suggestive when it is freed from the limited number of suggestions that occur through force of habit. But original thinking is rare precisely because habits do have such a compulsive power in determining the possibilities of action that suggest themselves to us. The man who moves in a rut of habitual reactions will "never think" of possibilities that "stare in the face" a less habit-ridden thinker. Inventiveness, originality, creative intelligence, whatever one chooses to call it, consists, in no small measure, in this ability to remain alive to a wide variety of stimuli, to keep sensitive to all the possibilities that are in a situation, instead of those only to which we are immediately prompted by instinct or habit. The possibility of using the current of a river as power is not the first possibility that flowing water suggests.

Past training and individual differences in temperament not only limit the possibilities that do occur to us; they seriously distort, color, and qualify those of which we become conscious. We forecast differently and with differing degrees of accuracy the consequences of those possible courses of action which do occur to us according to the influence and stimulation which particular native traits and acquired impulses have in our conduct. Ideally, the consequences which we imaginatively forecast as following from a given course of action, should tally with the consequences which genuinely follow from it. But there is too often a sad discrepancy between the consequences as they are foreseen by the individual concerned and the genuine consequences that could be foreseen by any disinterested observer. The discrepancy between the genuine and the imagined consequences of given ideas or suggestions is caused more than anything else by the hopes, fears, aversions, and preferences which, by nature or training, are controlling in a man's behavior. Facts are weighed differently according as one or another of these psychological influences is present. We intend unconsciously to subst.i.tute a desired or expected consequence for the actual one; we tend to be oblivious to consequences which we fear, and quick to imagine those for which we hope. On the day before an election the campaign managers on both sides, in the glow and momentum of their activities, are confident of the morrow's victory. The opponent of prohibition saw nothing but drug fiends and revolution as its consequences; its extreme advocates saw it as the salvation of mankind.

The causes of error in appraising the consequences of any given course of action are partly individual and partly social in character. From Francis Bacon down, there have been various attempts to cla.s.sify these factors in the distortion of the reflective process. In connection with the particular human traits, especially such as fear and gregariousness, we shall have occasion to examine a few of these.

It will suffice to point out here that the aim of reflective thinking is to discover the genuine consequences of things, and to eliminate and discount those prejudices and preferences, bred of early education and training, which might impair our discovery of those consequences. To the untrained, those things look most significant which stir their impulses most strikingly. The beggar's sores seem much more important and terrible than a gifted youngster deprived of education through poverty. Instinctively we shrink back from the sight of blood, but instinct is no safe clue in helping us to distinguish between the poisons and the panaceas among the brightly colored bottles of chemicals ranged along a shelf.

The whole technique of scientific method as opposed to the shrewd but unreliable guesses of common sense is one of freeing us from the compulsions of random habitual impulses.

It subst.i.tutes for caprice the measuring of consequences, the detailed knowing of what we are about. That impartial judgment has its difficulties is clear from the simple fact alone that human beings start by being a bundle of instincts and soon grow into a bundle of habits. To the extent to which they can control these they are masters of themselves.

THE VALUE OF REFLECTION FOR LIFE. To many people there is something terrifying about the idea of controlling life by reason. Life (they point out correctly) is a vital process of instincts which appear before thinking, and which are often more powerful than reasoned judgments. Against advice to live consciously, to be in control of ourselves, to know what we are about, comes the call "Back to Nature." A life of reflection appears chilling and arbitrary. Because reflection so often reveals that impulses must be checked if disaster is not to result, it has come to be a.s.sociated with a metallic and Stoic repression. To many a persuasive impulse we must, after reflection, say, "No." Because of this a certain school of philosophers, poets, and radicals urges us to trust nature, to follow our impulses, which, being natural, must be right.

All of these rebels against reason make the mistake of supposing that the aim of reflective thinking is to quell instincts, which, with the best will in the world, it cannot succeed in doing. Instincts are present and powerful. In themselves they are neither worth encouraging, nor ought they to be repressed. The satisfaction of native desires _is_ what we want.

The importance of reflective thinking is precisely that it helps us to secure those satisfactions. To surrender to every random impulse or every habitual prompting is to have neither satisfaction nor freedom. Reflection might be compared to the traffic policeman at the junction of two crowded thoroughfares.

If everyone were to drive his car pell-mell through the rush, if pedestrians, street cars, and automobiles were not to abide by the rules, no one would get anywhere, and the result would be perpetual accident and collision. In thinking we simply control and direct our impulses in the light of the consequences we can foresee. To thus guide and control action makes us genuinely free.

If a man's actions are not guided by thoughtful conclusions, they are guided by inconsiderate impulse, unbalanced appet.i.te, caprice, or the circ.u.mstances of the moment. To cultivate unhindered, unreflective external activity is to foster enslavement, for it leaves the person at the mercy of appet.i.te, sense, and circ.u.mstance.[1]

[Footnote 1: Dewey: _How We Think_, p. 67.]

Instincts and habits are fixed responses; being placed in such and such circ.u.mstances we _must_ do such and such things.

Only when we can vary our actions in the light of our own thinking are we masters of our environment rather than mechanically controlled by it.

THE SOCIAL IMPORTANCE OF REFLECTIVE BEHAVIOR. Reflection in the life of the individual insures that he will not become the slave of his own habits. He will regard habits as methods to be followed when they produce good results, to be discarded or modified when they do not. But if habit in the life of the individual needs control lest it become dangerously controlling, it needs it more conspicuously still in the life of the group.

Unless the individuals that compose a society are alert and conscious of the bearings of their actions, they will be completely and mechanically controlled by the customs to which they have been exposed in the early periods of their lives.

What an individual regards as right or wrong, what he will cherish or champion in industry, government, and art, depends in large measure on his early education and training and on the opinions and beliefs of other people with whom he repeatedly comes in contact. A society may be democratic in its political form and still autocratic in fact if the majority of its citizens are merely machines which can be set off to respond in certain determinate ways to customary stimuli of names, leaders, and party slogans. A society becomes genuinely democratic, precisely to the extent to which there is on the part of its citizens partic.i.p.ation in the important decisions affecting all their lives. But the partic.i.p.ation will only be a formality if votes are decided and opinions formed on the basis of habit alone.

REFLECTION REMOVED FROM IMMEDIATE APPLICATION--SCIENCE.

Thus far thinking has been discussed in its more practical aspects. And thinking is in its origins a very practical matter.

Literally, most people think when they have to, and only when they have to. Given a problem, a difficulty, a maladjustment between the individual and his environment, thinking occurs. If every instinctive act brought satisfaction, thinking would be much less necessary and much less frequently practiced. This is ill.u.s.trated in the performance of any act that once required attention and discrimination, and has later become habitual. We do not think how to walk, eat, and spell familiar words, how to find our way about familiar streets or even in familiar dark rooms. We _do_ think about where we shall spend our evenings or our summer, which courses we shall choose at college, which profession we shall enter. Where we are uneasy, drawn by competing impulses, we consider alternatives, measure consequences, and choose our course of action in the light of the results we can forecast. But while a large proportion of reflective behavior is thus practical in its origins and its results, it also occurs not infrequently where there is no immediate problem to be solved. Not all of men's energies are concerned in purely practical concerns. And part of man's superfluous vitality is expended in disinterested and curious inquiry into problems whose solutions afford no immediate practical benefits, but in the mere solving of which man finds satisfaction.

From the dawn of history, when some man a little more curious than his fellows, a little less absorbed in the hunting, the food-getting, and the fighting which were in those early days man's chief imperative business, first began to observe the mysterious recurrences in the world about him, the rising and setting of the sun, the return of the seasons, the movements of the tides and the stars, there have been individuals born with a marked and sometimes a pa.s.sionate desire to observe Nature and to generalize their observations. They have noted that, given certain conditions, certain results follow. They observe that animals with given similarities of form and structure have certain identical ways of life, that some substances are malleable and others not, that dew appears at certain times in the day on certain objects and not on others. They have generalized from these; and we now call such generalizations law. These generalizations when gathered into a system const.i.tute a science.

The sciences started out with unconfirmed guesses based on not very accurate information. As man's methods became more precise, he controlled the conditions under which observations were made, and the conditions under which generalizations were drawn from them. The control of the conditions and methods of observation const.i.tute what is known as induction in science. To this phase of the reflective process belong all the instruments for precise observation which characterize the scientific laboratory. The control of the methods by which generalizations or theories are built up from these facts is also part of the logic of induction, and includes all the canons and regulations for inductive inference.

But generalizations once made must be tested, and the elaboration of these generalizations, the a.n.a.lysis of them into their precise bearings, const.i.tute that part of the process of reasoning known as deduction. The final verification is again inductive, an experimental corroboration of theories by the facts already at hand and by facts additionally sought out and observed.

(These processes will be discussed in detail in the chapter on "Science and Scientific Method.")

However complicated the process of inquiry may become, the sciences remain essentially man's mode of satisfying his disinterested curiosity about the world in which he is living.

Through the sciences man makes himself, as has been so often said, at home in the world. He subst.i.tutes for the "blooming, buzzing confusion" which is the world as he first knows it, order, system, and law. Primitive man, absurd as seems to us his belief in a world of magic, of malicious demons and capricious G.o.ds, was trying to make sense out of the meaningless medley in which he seemed to find himself. Through science, modern man is likewise trying to make sense out of his world. The more apparently disconnected and incongruous facts that can be brought within the compa.s.s of simple and perfectly regular law, the less threatening or capricious seems the world in which we live. Where everything that happens is part of a system, we do not need, like the savage trembling in a thunderstorm, to be frightened at what will happen next. It is like moving in familiar surroundings among familiar people. Not all that goes on may be pleasant, but we can within limits predict what will happen, and are not puzzled and pained by continuous shocks and surprises.

We like order in the places in which we live, in our homes, in our cities, in the universe.

The sciences satisfy us not only in that they bring order into what at first seems the chaos of our surroundings, but in that they are themselves beautiful in their s.p.a.ciousness and their simplicity. We cannot pause here to consider the physiological facts which make us admire symmetry, but it is fundamental in our appreciation of music, poetry, and the plastic arts. From the sciences, likewise, we derive the satisfaction of symmetry on a magnificent scale. There is beauty as of a great symphony in the sweep and movement of the solar system. There is a quiet and infinite splendor about the changeless and comparatively simple structure which physics, in the broadest sense, reveals beneath the seeming multiplicity and variety of things. It is a desire for beauty as well as a thoroughgoing scientific pa.s.sion which prompts men like Poincare and Karl Pearson to seek for one law, one formula which, like "one clear chord to reach the ears of G.o.d,"

expresses the whole universe.

THE PRACTICAL ASPECT OF SCIENCE. But while the origins of science may lie in man's thirst for system, simplicity, and beauty in the world, the tremendous advance of science has a more immediate and practical cause. To understand the laws of Nature means to have the power of prediction; it means to know that, given certain circ.u.mstances, certain others follow always and inevitably; it means to discover causes--and their effects. Man having attained through patient inquiry this capacity to tell in advance, may take advantage of it for his own good. The whole of modern industry with its phenomenal control of natural powers and resources is testimony to the use which man has found for the facts and laws which he would never have found out save for the curiosity which was his endowment and the inquiry which he made his habit. "Knowledge is power,"

said Francis Bacon, and the three hundred years of science that have made possible the whole modern world of electric transportation, air travel between two continents, and instantaneous communication between remote parts of the world, have proved the aphorism. Man since his origin has tried to control his environment for his own good. The cave and the flint were his first rude attempts. In science with its accurate observation of facts not apparent to the unaided eye, and its discovery and demonstration of laws not found by casual and unsystematic common sense, man has an incomparably more refined instrument, and an incomparably more effective one. Thus, paradoxically enough, man's most disinterested and impartial activity is at the same time his most practical a.s.set.

THE CREATION OF BEAUTIFUL OBJECTS AND THE EXPRESSION OF IDEAS AND FEELINGS IN BEAUTIFUL FORM. Most men spend most of their lives necessarily in practical activity. Man's particular equipment of instincts survived in "the struggle for existence"

precisely because they were practical, because they did help the human creature to maintain his equilibrium in a half-friendly, half-hostile environment. Man acquires also, as already has been pointed out, habits that are useful to him, that bring him satisfactions not attainable through the random instinctive responses which are his at birth. Reflection, too, is, for the most part, severely practical in its origins and its responsibilities. It guides action into economical and useful channels.

Most of man's actions are thus ways of modifying his environment for immediately practical purposes. Man has instincts and habits which enable him to live. But in making those changes in the world which enable him to live better, man, as it were by accident, makes them beautifully. Pottery begins, for example, as a practical art, but the skilled potter cannot help spending a little excess vitality and habitual skill in adding a quite unnecessarily graceful curve, a gratuitous decoration to the utilitarian vessel he is making.

In the words of Santayana, "What had to be done was, by imaginative races, done imaginatively; what had to be spoken or made was spoken or made fitly, lovingly, beautifully....

The ceaseless experimentation and fermentation of ideas, in breeding what it had a propensity to breed, came sometimes on figments that gave it delightful pause."[1]
