ABSTRACT

Psychology studies the human being primarily as an individual. Sociology studies him primarily as one of a group. We have found both insights to be essential to the study of development in moral judgement; either in isolation would be inadequate. For we have seen from the outset that the child only becomes characteristically human in human society; it alone develops his personal and moral potential into actuality. In the moral sphere, therefore, there are two essential factors—the child himself and his environment. Both heredity and environment, both nature and nurture, are intricately involved.
