Abstract

Some consequences of direct realism and William James’s philosophy of mind are considered in terms of American naturalism as seen in the debate between John Dewey and Roy Wood Sellars. Sellars’s critical realism and evolutionary naturalism is compared and contrasted with Dewey’s pragmatic realism and emphatically evolutionary naturalism. Though these naturalisms are similar, there are significant differences between methodology, their critiques of James’s reflex arc concept in his Principles of Psychology, and the mind-body problem. Sellars’s critical realism and naturalism retains a priori commitments to fixed categories and concepts, whereas Dewey’s emphatically evolutionary pragmatic naturalism is empirical and sees continuities where Sellars insists on discontinuities. One significant difference is Sellars’s maintaining a place for introspection as methodologically appropriate and Dewey’s’ rejection of it. These differences are illustrated through Sellars’s modification of the reflex arc to include an organic but interpretative step, and Dewey’s radical criticism of approaches like James’s and Sellars’s as recapitulating the Cartesian dualism that such views intended to overcome. These differences are finally contrasted in Sellars’s maintaining a privacy of mind by constraining it to the brain in a dual-aspect theory, while Dewey advocates mind as sociocultural, expanding mind into body and world.
