one from another in the great river valleys of the world in the course of five or six thousand years. They developed mental dispositions and traditions and attitudes of thought one to another. The civilization in which we live to-day is simply carrying on and still further developing and working out and rearranging these relationships. This is the world from which we inherit. It is only by the attentive study of their origins that we can detach ourselves from the prejudices and immediate ideas of the particular class to which we may belong, and begin to understand the social and political questions of our own time.
