Abstract

This is a study of "three metaphysical naturalists" who, although minor figures in their own right, nonetheless substantially influenced the direction and cast of American naturalism. The theme that unites them, according to Delaney, is their reaction to the bifurcation of mind and corporeal nature bequeathed to modern philosophy by Descartes and Locke. Morris R. Cohen, as a logician and philosopher of science, saw such a bifurcation as engendering conventionalism and a type of nominalism in science, and he reacted against these with his own "logical realism." Frederick J. E. Woodbridge, working out of the Aristotelian and Spinozistic traditions, saw it as entailing subjectivism and attempted to counteract this by reasserting an "experiential realism." Roy Wood Sellars, himself an evolutionist, viewed the duality of mind and nature as a stimulus for the imaginative projection of idealism and the quietistic escapism of spiritualism, and countered these with a thorough-going "materialistic humanism." Delaney elaborates his thesis with clarity and cogency, using it as a vehicle to reconstruct the metaphysical views of the three men under study. He concludes with a critical comparison of the resulting "naturalistic reintegrations" of the mind-nature bifurcation: Cohen's through a more adequate philosophy of science, Woodbridge's by a realistic theory of experience, and Sellars' by an emergent theory of evolution. Delaney's critique focuses on the fundamental notions of existence, nature, and man, using these to expose essential differences between the "metaphysics" of the New York naturalists and that of Sellars. Woodbridge emerges from Delaney's analysis as the most substantial philosopher of the group. This is not a ponderous tome--it can be read practically at one sitting--but it succeeds in throwing new light on American naturalism in terms of its positive contributions to both the philosophy of nature and the philosophy of mind.--W.
