Further, as self-consciousness varies, the amount or degree of this remaking activity will vary. Among the extremely few respects in which human history shows unquestionable growth we must include the degree and range of self-consciousness. The gradual development of psychology as a science and the persistent advance of the subjective or introspective element in literature and in all fine art are tokens of this change. And as a further indication and result, the art of human reshaping has taken definite character, has left its incidental beginnings far behind, has become an institution, a group of institutions.
Wherever a language exists, as a magazine of established meanings, there will be found a repertoire of epithets of praise and blame, at once results and implements of this social process. The simple existence of such a vocabulary acts as a persistent force; but the effect of current ideals is redoubled when a coherent agency, such as public religion, assumes protection of the most searching social maxims and lends to them the weight of all time, all space, all wonder, and all fear. For many centuries religion held within itself the ripening self-knowledge and self-discipline of the human mind. Now, beside this original agency we have its offshoots, politics, education, legislation, the penal art. And the philosophical sciences, including psychology and ethics, are the especial servants of these arts.
As to structure, human nature is undoubtedly the most plastic part of the living world, the most adaptable, the most educable. Of all animals, it is man in whom heredity counts for least, and conscious building forces for most. Consider that his infancy is longest, his instincts least fixed, his brain most unfinished at birth, his powers of habit-making and habit-changing most marked, his susceptibility to social impressions keenest; and it becomes clear that in every way nature, as a prescriptive power, has provided in him for her own displacement. His major instincts and passions first appear on the scene, not as controlling forces, but as elements of play, in a prolonged life of play. Other creatures nature could largely finish: the human creature must finish himself.
And as to history, it cannot be said that the results of man's attempts at self-modeling appear to belie the liberty thus promised in his constitution. If he has retired his natural integument in favor of a device called clothing, capable of expressing endless nuances, not alone of status and wealth, but of temper and taste as well—conservatism or venturesomeness, solemnity, gaiety, profusion, color, dignity, carelessness or whim, he has not failed to fashion his inner self into equally various modes of character and custom. That is a hazardous refutation of socialism which consists in pointing out that its success would require a change in human nature. Under the spell of particular ideas monastic communities have flourished, in comparison with whose demands upon human nature the change required by socialism—so far as it calls for purer altruism and not pure economic folly—is trivial. To any one who asserts as a dogma that "human nature never changes," it is fair to reply, "It is human nature to change itself."
When one reflects to what extent racial and national traits are manners of the mind, fixed by social rather than by physical heredity, while the bodily characters themselves may be due in no small measure to sexual choices at first experimental, then imitative, then habitual, one is not disposed to think lightly of the human capacity for self-modification. But it is still possible to be skeptical as to the depth and permanence of any changes which are genuinely voluntary. There are few maxims of conduct, and few laws so contrary to nature that they could not be put into momentary effect by individuals or by communities. Plato's Republic has never been fairly tried; but fragments of this and other Utopias have been common enough in history. No one presumes to limit what men can attempt; one only inquires what the silent forces are which determine what can last.
What, to be explicit, is the possible future of measures dealing with divorce, with war, with political corruption, with prostitution, with superstition? Enthusiastic idealism is too precious an energy to be wasted if we can spare it false efforts by recognizing those permanent ingredients of our being indicated by the words pugnacity, greed, sex, fear. Machiavelli was not inclined to make little of what an unhampered ruler could do with his subjects; yet he saw in such passions as these a fixed limit to the power of the Prince. "It makes him hated above all things to be rapacious, and to be violator of the property and women of his subjects, from both of which he must abstain." And if Machiavelli's despotism meets its master in the undercurrents of human instinct, governments of less determined stripe, whether of states or of persons, would hardly do well to treat these ultimate data with less respect.
2. Human Nature, Folkways, and the Mores[66]
It is generally taken for granted that men inherited some guiding instincts from their beast ancestry, and it may be true, although it has never been proved. If there were such inheritances, they controlled and aided the first efforts to satisfy needs. Analogy makes it easy to assume that the ways of beasts had produced channels of habit and predisposition along which dexterities and other psycho-physical activities would run easily. Experiments with new born animals show that in the absence of any experience of the relation of means to ends, efforts to satisfy needs are clumsy and blundering. The method is that of trial and failure, which produces repeated pain, loss, and disappointments. Nevertheless, it is the method of rude experiment and selection. The earliest efforts of men were of this kind. Need was the impelling force. Pleasure and pain, on the one side and the other, were the rude constraints which defined the line on which efforts must proceed. The ability to distinguish between pleasure and pain is the only psychical power which is to be assumed. Thus ways of doing things were selected which were expedient. They answered the purpose better than other ways, or with less toil and pain. Along the course on which efforts were compelled to go, habit, routine, and skill were developed. The struggle to maintain existence was carried on, not individually, but in groups. Each profited by the other's experience; hence there was concurrence toward that which proved to be most expedient.
All at last adopted the same way for the same purpose; hence the ways turned into customs and became mass phenomena. Instincts were developed in connection with them. In this way folkways arise. The young learn them by tradition, imitation, and authority. The folkways, at a time, provide for all the needs of life then and there. They are uniform, universal in the group, imperative, and invariable.
The operation by which folkways are produced consists in the frequent repetition of petty acts, often by great numbers acting in concert or, at least, acting in the same way when face to face with the same need. The immediate motive is interest. It produces habit in the individual and custom in the group. It is, therefore, in the highest degree original and primitive. Out of the unconscious experiment which every repetition of the ways includes, there issues pleasure or pain, and then, so far as the men are capable of reflection, convictions that the ways are conducive to social welfare. When this conviction as to the relation to welfare is added to the folkways, they are converted into mores, and, by virtue of the philosophical and ethical element added to them, they win utility and importance and become the source of the science and the art of living.
