ion, 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 bui
