Sellars is well known for his critique of the “myth of the given” in his “Empiricism and the Philosophy of Mind”. That text does not make it unambiguous just how he understands the “myth”. Here I take it that whatever else may be involved, his critique is incompatible with the view that there is a nonconceptual mode of “presentation” or “givenness” of particulars that is the heart of sense perception and what is most distinctive of perception as a type of (...) cognition. A critical examination of Sellars’ arguments, particularly those directed at the Theory of Appearing, results in the conclusion that he has failed to eliminate the above view of perception. Moreover, though Sellars is clearly opposed to the view that perceptual experience cannot provide justification for beliefs about perceived objects, I argue that Sellars has failed to shake the intuitive plausibility of that view.

Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another.

Coherence theorists have universally defined justification as a relation only among (the contents of) belief states, in contradistinction to other theories, such as some versions of founda­tionalism, which define justification as a relation on belief states and appearance states.

The brain-in-a-vat argument for skepticism is best formulated, not using the closure principle, but using the “Preference Principle,” which states that in order to be justified in believing H on the basis of E, one must have grounds for preferring H over each alternative explanation of E. When the argument is formulated this way, Dretske’s and Klein’s responses to it fail. However, the strengthened argument can be refuted using a direct realist account of perception. For the direct realist, refuting the (...) SIV scenario is not a precondition on knowledge of the external world, and only the direct realist can give a non-circular account of how we know we’re not brains in vats. (shrink)

I oppose the popular view that the phenomenal character of perceptual experience consists in the subject's representing the (putative) perceived object as being so-and-so. The account of perceptual experience I favor instead is a version of the "Theory of Appearing" that takes it to be a matter of the perceived object's appearing to one as so-and-so, where this does not mean that the subject takes or believes it to be so-and-so. This plays no part in my criticisms of Representationalism. I (...) mention it only to be up front as to where I stand. My criticism of the Representationalist position is in sections. (1) There is no sufficient reason for positing a representative function for perceptual experience. It doesn't seem on the face of it to be that, and nothing serves in place of such seeming. (2) Even if it did have such a function, it doesn't have the conceptual resources to represent a state of affairs. (3) Even if it did, it is not suited to represent, e.g., a physical property of color. (4) Finally, even if I am wrong about the first three points, it is still impossible for the phenomenal character of the perceptual experience to consist in it's representing what it does. My central argument for this central claim of the paper is that it is metaphysically, de re possible that one have a certain perceptual experience without it's presenting any state of affairs. And since all identities hold necessarily, this identity claim fails. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

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.
