Abstract

John Dewey began his career as an absolute idealist, holding that the universe is a construct of an absolute mind in which human minds participate; human ideas are true when they reproduce the absolute's ideas; and human conduct is right when it realizes the absolute's goals for human progress. Twenty years later Dewey had abandoned idealism for instrumentalism, asserting that ideas are instruments for the manipulation of human experience and that conduct is right when it generates a satisfactory relationship between agents and their environments. However, scholars disagree about when, why, and how this transformation of Dewey's thought occurred. I review the development of Dewey's moral epistemology from 1884 to 1908 to answer these questions. ;In chapters I and II, I examine the sources and nature of Dewey's early idealism, relating it to the views of contemporary idealists such as T. H. Green, F. H. Bradley, G. S. Morris, and to the views of A. Comte. By the latter Dewey was inspired to seek a reconciliation of physical science and morals, despite the reservations of his fellow idealists. In Chapters III and IV, I discuss Dewey's first two ethics texts , each an attempt to overcome idealist objections to reconciling ethics and science. Both were critical failures, forcing Dewey to rethink his position. In chapter V, I argue that collaboration with experimental psychologists at the University of Chicago transformed Dewey's understanding of science. He then came to see scientific ideas and principles as instruments for manipulating human experience and, gradually, all ideas in the same light. By 1902, Dewey had abandoned his earlier idealist notions for instrumentalism and begun to construct new arguments for reconciling science and ethics. In chapters VI and VII, I explicate and defend the reconciliation Dewey achieved through use of his new instrumentalist moral epistemology in his 1908 Ethics
