We think that certain of our mental states represent the world around us, and represent it in determinate ways. My perception that there is salt in the pot before me, for example, represents my immediate environment as containing a certain object, a pot, with a certain kind of substance, salt, in it. My belief that salt dissolves in water represents something in the world around me, namely salt, as having a certain observational property, that of dissolving. But what exactly is the relation between such states and the world beyond the surfaces of our skins? Specifically, what exactly is the relation between the contents of those states, and the world beyond our bodies?

Externalism in the philosophy of mind has been thought by many to pose a serious threat to the claim that subjects are in general authoritative with regard to certain of their own intentional states.¹ In a series of papers, Tyler Burge (1985_a_, 1985_b_, 1988, 1996) has argued that the distinctive entitlement or right that subjects have to self- knowledge in certain cases is compatible with externalism, since that entitlement is environmentally neutral, neutral with respect to the issue of the individuation dependence of subjects' intentional states on factors beyond their bodies. His reason is that whereas externalism—the view that certain intentional states of persons are individuation-dependent on objects and/or phenomena external to their bodies—is a metaphysical thesis, authoritative self-knowledge is an epistemological matter. This being so, there is no reason to suppose that the two need conflict with one another
