Rationality II & III

Against Naturalizing Rationality

Recent obituaries for traditional non-naturalistic approaches to rationality are not just premature but demonstrably self-defeating. One such prominent obituary appears in the writings of W. V. Quine, whose pessimism about traditional epistemology stems from his scientism, the view that the natural sciences have a monopoly on legitimate theoretical explanation. Quine also offers an obituary for the a priori constraints on rationality found in “first philosophy”, resting on his rejection of the “pernicious mentalism” of semantic theories of meaning. Quine’s pronouncements of the death of traditional conceptions of rationality in epistemology and in the theory of meaning are, we contend, but misguided wishes for their death, wishes that face severe problems of self-defeat. In addition, Quine’s naturalistic epistemology is subject to damaging skeptical worries, the force of which one cannot escape by ignoring them. A non-naturalistic approach to rationality is here to stay, whether friends of Quine’s naturalism like it or not. Any sweeping claim that non-naturalistic accounts of rationality are dead will face insurmountable obstacles from unavoidable questions about its own rational justification. Such questions will keep non-naturalistic epistemology and first philosophy alive forever, or at least as long as philosophers endure.
