144 THE AMERICAN JOURNAL OF SOCIOLOGY
what other men have thought and said as to suppose that the assump- tion of the psychical as the determining factor in social movements marks a recent change of front in sociology. Since Schaffle and De Greef in Europe, and Ward in this country, the assumption has been decisive and all but universal. With every recent investigator worth consideration, the sociological problem has been some part of the problem of discovering the ways in which psychic factors work in society. The sociologist who does not know this must have followed Comte's programme of refusing to consult the writings of others. In calling attention to the relations of psychic facts and of psychological science to the social and the sociological, we are not exploiting a novelty. We are still within the limits of the familiar and the practi- cally undisputed. The doubt is about tht formulas of psychical force,
not about its presence nor its prevalence.
