Abstract

For traditional epistemologists like myself the rise in popularity of externalist epistemologies has made philosophical life more than a little difficult. The debate between internalist and externalist analyses of knowledge and justification has implications that range far beyond the immediate topic in dispute—the nature of knowledge and justified belief. This paper was written for a conference titled "Can Epistemology Be Unified?" Whether or not it can be unified, it certainly is not at the present time. To say that a field of philosophy is unified is not, of course, to say that there is universal agreement on the answers to fundamental questions—if unification required that, then no field of philosophy would ever be unified. It is enough for epistemology to be unified that epistemologists recognize the legitimacy or philosophical interest of the same kinds of questions and recognize the legitimacy of the same general philosophical methodology. Both internalists and externalists are indeed addressing a common question when they ask about the nature of knowledge and justified belief, when the ask, that is, metaepistemological questions. Moreover, as far as I can tell, in attempting to answer metaepistemological questions, epistemologists employ more or less the classic methodology of analytic philosophy—analyses of epistemic concepts seek necessary and sufficient conditions for the application of epistemic concepts, and proposals are evaluated with the thought experiments that have been the stock in trade of analytic philosophy for centuries. The field of metaepistemology is unified. If the externalist's metaepistemology were correct, however, we would need to rethink the entire conceptual framework within which philosophers have addressed a host of epistemological and even metaphysical issues. If paradigm externalists were correct, philosophers, qua philosophers, should stop asking certain questions they used to find very interesting and should even abandon certain methods of doing philosophy. In this paper I am primarily interested in the implications of an externalist epistemology for the classic debate over direct realism concerning the external world. After suggesting that even externalists might need to abandon epistemological direct realism and outlining a problem that that might cause, I'll close with some very general remarks on how different the epistemic landscape becomes given the way in which externalists understand the distinction between inferentially and noninferentially justified belief.
