With what philosophical point of view did I begin my career as teacher? Looking back to that period, I see that it was a rather inchoate form of idealism, reflecting the liberal Protestant orientation I had then adopted. This idealism was gradually revised to make room for major aspects of Deweyan instrumentalism. In my years at Columbia, Dewey had impressed me as a person, and during my decade in Chicago, in close contact with colleagues whom he had deeply influenced, I came to accept what appeared to be the core of his contribution to philosophy. But continued sensitivity to insights from various quarters prevented me from becoming a disciple of any one philosopher or philosophical school.
