But what goes by the name to-day is a potpourri in which one can distinguish descriptions of legal forms, charters and institutions; comparative studies of governmental and social machinery; the history of institutions, a few "principles" like the law of rent, some moral admonitions, a good deal of class feeling, not a little timidity--but almost no attempt to cut beneath these manifestations of social life to the creative impulses which produce them. The Economic Man--that lazy abstraction--is still paraded in the lecture room; the study of human nature has not advanced beyond the gossip of old wives.

Graham Wallas touched the cause of the trouble when he pointed out that political science to-day discusses institutions and ignores the nature of the men who make and live under them. I have heard professors reply that it wasn't their business to discuss human nature but to record and interpret economic and political facts. Yet if you probe those "interpretations" there is no escaping the conclusion that they rest upon some notion of what man is like. "The student of politics," writes Mr. Wallas, "must, consciously or unconsciously, form a conception of human nature, and the less conscious he is of his conception the more likely he is to be dominated by it." For politics is an interest of men--a tool which they fabricate and use--and no comment has much value if it tries to get along without mankind. You might as well try to describe food by ignoring the digestion.

Mr. Wallas has called a halt. I think we may say that his is the distinction of having turned the study of politics back to the humane tradition of Plato and Machiavelli--of having made man the center of political investigation. The very title of his book--"Human Nature in Politics"--is significant. Now in making that statement, I am aware that it is a sweeping one, and I do not mean to imply that Mr. Wallas is the only modern man who has tried to think about politics psychologically. Here in America alone we have two splendid critics, a man and a woman, whose thought flows from an interpretation of human character. Thorstein Veblen's brilliant descriptions penetrate deeply into our mental life, and Jane Addams has given new hope to many of us by her capacity for making ideals the goal of natural desire.

Nor is it just to pass by such a suggestive thinker as Gabriel Tarde, even though we may feel that his psychology is too simple and his conclusions somewhat overdriven by a favorite theory. The work of Gustav Le Bon on "crowds" has, of course, passed into current thought, but I doubt whether anyone could say that he had even prepared a basis for a new political psychology. His own aversion to reform, his fondness for vast epochs and his contempt for current effort have left most of his "psychological laws" in the region of interesting literary comment. There are, too, any number of "social psychologies," such as those of Ross and McDougall. But the trouble with them is that the "psychology" is weak and uninformed, distorted by moral enthusiasms, and put out without any particular reference to the task of statesmanship. When you come to special problems, the literature of the subject picks up. Crime is receiving valuable attention, education is profoundly affected, alcoholism and sex have been handled for a good while on a psychological basis.

But it remained for Mr. Wallas to state the philosophy of the matter--to say why the study of human nature must serve politics, and to point out how. He has not produced a political psychology, but he has written the manifesto for it. As a result, fragmentary investigations can be brought together and applied to the work of statecraft. Merely by making these researches self-conscious, he has made clearer their goal, given them direction, and kindled them to practical action. How necessary this work is can be seen in the writing of Miss Addams. Owing to keen insight and fine sympathy her thinking has generally been on a human basis. Yet Miss Addams is a reformer, and sympathy without an explicit philosophy may lead to a distorted enthusiasm. Her book on prostitution seems rather the product of her moral fervor than her human insight. Compare it with "The Spirit of Youth" or "Newer Ideals of Peace" or "Democracy and Social Ethics" and I think you will notice a very considerable willingness to gloss over human need in the interests of an unanalyzed reform. To put it bluntly, Miss Addams let her impatience get the better of her wisdom. She had written brilliantly about sex and its "sublimation," she had suggested notable "moral equivalents" for vice, but when she touched the white slave traffic its horrors were so great that she also put her faith in the policeman and the district attorney. "A New Conscience and an Ancient Evil" is an hysterical book, just because the real philosophical basis of Miss Addams' thinking was not deliberate enough to withstand the shock of a poignant horror.

It is this weakness that Mr. Wallas comes to remedy. He has described what political science must be like, and anyone who has absorbed his insight has an intellectual groundwork for political observation. No one, least of all Mr. Wallas, would claim anything like finality for the essay. These labors are not done in a day. But he has deliberately brought the study of politics to the only focus which has any rational interest for mankind. He has made a plea, and sketched a plan which hundreds of investigators the world over must help to realize. If political science could travel in the direction suggested, its criticism would be relevant, its proposals practical. There would, for the first time, be a concerted effort to build a civilization around mankind, to use its talent and to satisfy its needs. There would be no more empty taboos, no erecting of institutions upon abstract and mechanical analogies. Politics would be like education--an effort to develop, train and nurture men's impulses. As Montessori is building the school around the child, so politics would build all of social life around the human being.

That practical issues hang upon these investigations can be shown by an example from Mr. Wallas's book. Take the quarrel over socialism. You hear it said that without the private ownership of capital people will lose ambition and sink into sloth. Many men, just as well aware of present-day evils as the socialists, are unwilling to accept the collectivist remedy. G. K. Chesterton and Hilaire Belloc speak of the "magic of property" as the real obstacle to socialism. Now obviously this is a question of first-rate importance. If socialism will destroy initiative then only a doctrinaire would desire it. But how is the question to be solved? You cannot reason it out. Economics, as we know it to-day, is quite incapable of answering such a problem, for it is a matter that depends upon psychological investigation. When a professor says that socialism is impracticable he begs the question, for that amounts to assuming that the point at issue is already settled. If he tells you that socialism is against human nature, we have a perfect right to ask where he proved the possibilities of human nature.

But note how Mr. Wallas approaches the debate: "Children quarrel furiously at a very early age over apparently worthless things, and collect and hide them long before they can have any clear notion of the advantages to be derived from individual possession. Those children who in certain charity schools are brought up entirely without personal property, even in their clothes or pocket handkerchiefs, show every sign of the bad effect on health and character which results from complete inability to satisfy a strong inherited instinct.... Some economist ought therefore to give us a treatise in which this property instinct is carefully and quantitatively examined.... How far can it be eliminated or modified by education? Is it satisfied by a leasehold or a life-interest, or by such an arrangement of corporate property as is offered by a collegiate foundation, or by the provision of a public park? Does it require for its satisfaction material and visible things such as land or houses, or is the holding, say, of colonial railway shares sufficient? Is the absence of unlimited proprietary rights felt more strongly in the case of personal chattels (such as furniture and ornaments) than in the case of land or machinery? Does the degree and direction of the instinct markedly differ among different individuals or races, or between the two sexes?"

This puts the argument upon a plane where discussion is relevant. This is no trumped-up issue: it is asked by a politician and a socialist seeking for a real solution. We need to know whether the "magic of property" extends from a man's garden to Standard Oil stocks as anti-socialists say, and, conversely, we need to know what is happening to that mass of proletarians who own no property and cannot satisfy their instincts even with personal chattels.

For if ownership is a human need, we certainly cannot taboo it as the extreme communists so dogmatically urge. "Pending ... an inquiry," writes Mr. Wallas, "my own provisional opinion is that, like a good many instincts of very early evolutionary origin, it can be satisfied by an avowed pretense; just as a kitten which is fed regularly on milk can be kept in good health if it is allowed to indulge its hunting instinct by playing with a bobbin, and a peaceful civil servant satisfies his instinct of combat and adventure at golf."
