From etiquette and social distinction, from formalities of conversation and correspondence, of greeting and farewell, of condolence and congratulation to the most important "customs of the country," with respect to marriage, property, and the like, ways of acting are maintained by the mechanism of habit rather than by arbitrary law or equally arbitrary instinctive caprice.
Disserviceable habits in the individual. Habitual behavior which can become so completely controlling in the lives of so many people is not without its dangers. The nervous system is originally neutral, and can be involved on the side either of good or evil. A human born with a plastic brain and nervous system must acquire habits, but that he will acquire good habits (that is, habits serviceable to his own happiness and to that of his fellows) is not guaranteed by nature. Habits are indeed more notorious than famous, and examples are more frequently chosen from evil ones than from good. Promptness in the performance of one's professional or domestic duties, care in speech, in dress and in demeanor, are, once they are acquired, permanent assets. But if these fail to be developed, dishonesty or superficiality, slovenliness in dress and speech, and surliness in manner, may and do become equally habitual. The significance of this has been eloquently stated at the close of James's famous discussion:
The hell to be endured hereafter, of which theology tells, is no worse than the hell we make for ourselves in this world by habitually fashioning our characters in the wrong way. Could the young but realize how soon they will become mere walking bundles of habits, they would give more heed to their conduct while in the plastic state. We are spinning our own fates, good or evil, and never to be undone. Every smallest stroke of virtue or of vice leaves its never-so-little scar. The drunken Rip Van Winkle, in Jefferson's play, excuses himself for every fresh dereliction by saying, "I won't count this time!" Well, he may not count it, and a kind Heaven may not count it, but it is being counted none the less. Down among his nerve cells and fibres, the molecules are counting it, registering and storing it up to be used against him when the next temptation comes. Nothing we ever do is, in strict scientific literalness, wiped out.[1]

Social inertia. If the acquisition of bad, that is, disserviceable habits, is disastrous to the individual, it is in some respects even worse in the group. The inertia of the nervous system, the tendency to go on repeating connections that have once been made is one of the strongest obstacles to change, however desirable. It is not only that habits of action have been established, but that with them go deep-seated habits of thought and feeling. The repression of people's accustomed ways of doing things may bring with it a sense of frustration almost as complete and painful as if these obstructed activities were instinctive. This is not true merely in the melodramatic instances of drug addicts and drunkards. It is true in the case of social habits which have become established in a large group. Any Utopian that dreams of revolutionizing society overnight fails to take into account the enormous control of habits over groups which have acquired them, and the powerful emotions, amounting sometimes to passion, which are aroused by their frustration.
The importance of the learning habit. That habit is at once the conserver and the petrifier of society has long been recognized by social philosophers. There is one habit, however, the acquisition of which is itself a preventive of the complete domination of the individual or the group by hard and fast routine. This is the habit of learning, which is necessary to the acquisition of any habits at all. Man in learning new habits, "learns to learn." This ability to learn is, of course, correlated with a plasticity of brain and nerve fiber which is most present in early youth. The disappearance of this capacity is hastened by the pressure which forces individuals in their business and professional life to cling fast to certain habits which are prized and rewarded by the group. A sedulous cultivation on the part of the individual of the habit of open-minded inquiry, of the habit of learning, and the encouragement of this tendency by the group are the only antidotes that can be provided against this marked physiological tendency to fossilization and the frequent social tendencies in the same direction.
Whether habits shall master us, or whether we shall be their masters, depends also on the method by which they were acquired. If they were learned merely through mechanical drill, they will be fixed and rigid. If they were learned deliberately to meet new situations, they will not be retained when the conditions they were acquired to meet are utterly changed.
The specificity of habits. One important consideration, finally, that must be brought to consideration is that habits are, like instincts, specific. They are not general "open sesames" which, learned in one situation, will apply with indiscriminate miraculousness to a variety of others. Just as an instinct is a definite response to a definite stimulus, so is a habit. The chief and almost only observable difference is that the former is unlearned, while the latter is learned or acquired.
But while habits are specific, they are within limits transferable. Such is the case when a situation which calls out a certain habitual response is paralleled in significant points by another. Thus the situation, one's - room - at - home - cluttered - up - with - a - miscellany - of - books - papers - tennis - apparatus - and - clothing, has sufficiently similar significant points to the situation, one's - office - littered - with - documents - old - letters - manuscripts - blueprints - and - proofs, to call forth, if the habit has been established in one case, the identical response of "tidying up" in the other. But unless there are marked points of similarity between two different sets of circumstances, specific habits remain specific and non-transferable. There is in the laws of habit no guarantee that an industrious application to the batting averages of the major league on the part of an alert twelve-year-old will provoke the same assiduous assimilation of the facts of the American Revolution; that a boy who works hard at his chemistry will work equally hard at his English, or that one who is careful about his manners and pronunciation in school will display the slightest heed to them among his companions on the ball-field. One of the most cogent arguments against the stereotyped teaching of Latin and Greek has been the serious doubt psychologists have held as to whether four years' training in Latin syntax will develop in the student general mental habits which will be applicable or useful outside the Latin classroom.
The older "faculty" psychologists presumed that different subjects trained various so-called "faculties" of "memory," "imagination," and "intellect." It has now become clear on experimental evidence that in education we are training no isolated faculties, but are training the individual to certain specific habits. The more widely applicable the habits are, obviously the more valuable or dangerous will they be in the conduct of life. But when habits do become general, such as a habit of promptness, honesty, and regularity, not in one situation but "in general," it is because they are something more than habits in the strict physiological sense. They are intellectual as well as merely motor in character; they are deliberate and conscious methods rather than mechanical rules of thumb. Habits that have been drilled into an individual will appear only when the situation very closely approximates the one in which the drill has been performed. The cat that has learned to get out of a certain type of cage by pressing a button will be utterly at a loss if the familiar features of the cage are changed. The intelligent human will detect and take pains to detect among the minor differences of the situation some significant fact which he has met in another setting, and he will apply a habit useful in this new situation despite the slightly changed accompanying circumstances. The man who can drive an automobile with reflective appreciation of the processes involved, who knows, as we say, what he is doing, will not long be baffled by a car with a slightly different arrangement of levers and steering-gear, nor be completely frustrated when the car for some reason fails to move. As happened in many notable instances during the World War, trained executives were not long at a loss when they shifted from the management of a steel plant to a shipyard, or from large-scale mining operations in Montana to large-scale relief work in Belgium.
