To have lived one's way in the Western world from the middle of the nineteenth century into the middle of the twentieth, and to have had a major part in shaping the intellectual character of the time through which one lived, is not only an extraordinary achievement in itself, but an achievement with many additional consequences. In John Dewey's case, one of these lies in the development of a philosophical framework for social thought which fuses social science with psychology and the natural sciences in a modern form of logic and empirical philosophy. Another lies in the lessons to be learned by students of social history from a life so entirely devoted to teaching, writing and philosophical thinking in the environment of the university and its surrounding communities.
