Democracy and Education
(1916)
“ Every step forward in the social sciences—the studies termed history, economics, politics, sociology—shows that social questions are capable of being intelligently coped with only in the degree in which we employ the method of collecting data, forming hypotheses, and testing them in action which is characteristic of natural science, and in the degree in which we utilize in behalf of the promotion of social welfare the technical knowledge ascertained by physics and chemistry. ”
