This paper aims to investigate the transformations undergone by Dewey’s philosophy in the period from 1916 to 1921. By analyzing three different problematic situations with which Dewey found himself confronted (German militarism; the effects of propaganda on American society; the experience of a two-year stay in China), the paper seeks to show the various lines of development at work in his thought. The thesis of the paper is that in the war and immediately post-war years Dewey was concerned with outlining (...) a new account of the nature of theory which was preliminary to the formulation of his social philosophy. The paper presents Dewey’s main philosophical achievements, with the aim of providing some background knowledge that could be useful to understanding that place and significance of the Lectures in China in the overall context of his thought.
