In this paper I characterize the problem of first-person authority as it confronts the proponent of the belief box conception of belief, and I develop the groundwork for a belief box account of that authority. If acceptable, the belief box account calls into question (by undermining a popular motivation for) the thesis that first-person authority is not to be traced to a truth-tracking relation between first-person opinions themselves and the beliefs which they are about.

Social externalism is the view that the contents of a person's propositional attitudes are logically determined at least in part by her linguistic community's standards for the use of her words. If social externalism is correct, its importance can hardly be overemphasized. The traditional Cartesian view of psychological states as essentially first personal and non-relational in character, which has shaped much theorizing about the nature of psychological explanation, would be shown to be deeply flawed.

According to the expressive theory of communication, the primary function of language is to enable speakers to convey the content of their thoughts to hearers. According to Tyler Burge's social externalism, the content of a person's thought is relative to the way words are used in his or her surrounding linguistic community. This paper argues that Burge's social externalism refutes the expressive theory of communication.

Incompatibilism is the view that privileged knowledge of our own mental states cannot be reconciled with externalism regarding the content of mental states. Davidson has recently developed two arguments that are supposed to disprove incompatibilism and establish the consistency of privileged access and externalism. One argument criticizes incompatibilism for assuming that externalism conflicts with the mind?body identity theory. Since mental states supervene on neurological events, Davidson argues, they are partly ?in the head? and are knowable just by reflection. Another argument rejects incompatibilism by repudiating the object perception model of introspection. Once extemalism is freed from the internalist idea that thoughts take objects which are inner epistemological intermediaries, Davidson maintains, it poses no threat to privileged self?knowledge. It is argued that neither of these arguments is successful, since both disprove assumptions irrelevant to incompatibilism. Moreover, it is indicated how Davidson would have to go about defending his positive account of privileged self?knowledge against the principal incompatibilist arguments.

Externalism about content is the view that the social and / or the physical environment contributes to determining the content of the beliefs of a person. The strongest argument for social externalism derives from the rule-following considerations that motivate a social theory of conceptual content. The best argument for physical externalism goes back to Putnam’s twin earth thought experiment. The aim of this paper is to point out that these two sorts of externalism give contradictory accounts of what determines the conceptual content of our beliefs and individuates them. According to physical externalism, the physical environment is sufficient to perform that task owing to suitable causal relations. According to social externalism, the conceptual content of our beliefs is determined by us owing to certain social practices. Possible strategies to reconcile both these accounts are considered.

Recent social psychology is skeptical about self-knowledge. Philosophers, on the other hand, have produced a new account of the source of the authority of self-ascriptions. On this account, it is not descriptive accuracy but authorship which funds the authority of one's self-ascriptions. The resulting view seems to ensure that self-ascriptions are authoritative, despite evidence of one's fallibility. However, a new wave of psychological studies presents a powerful challenge to the authorship account. This research suggests that one can author one's attitudes, but one's self- ascriptions may lack authority. I present this new challenge from social psychology and use it to argue that first-person authority is agential authority: one's self-ascriptions are authoritative, in part anyway, because they are reliable expressions of those attitudes that govern further choices and behavior.

Externalism in the philosophy of mind is threatened by the view that subjects are authoritative with regard to the contents of their own intentional states. If externalism is to be reconciled with first-person authority, two issues need to be addressed: (a) how the non-evidence-based character of knowledge of one's own intentional states is compatible with ignorance of the empirical factors that individuate the contents of those states, and (b) how, given externalism, the non-evidence-based character of such knowledge could place its subject in an authoritative position. This paper endorses a standard strategy for dealing with (a). The bulk of the paper is devoted to (b). The aim is to develop an account of first-person authority for a certain class of intentional states that is capable of explaining (1) why knowledge of one's own intentional states is peculiarly authoritative, and (2) why such authority is compatible with externalism.

Ever since the 1970’s, philosophers of mind have engaged in a lively discussion of Externalism. Externalism is the metaphysical thesis that the contents of one’s thoughts are determined partly by empirical features of one’s environment. Externalism appears to clash with another plausible thesis—the epistemological thesis that one can have knowledge of one’s own thoughts, without evidence or empirical investigation. Many have argued that the conjunction of these theses is incompatible. I have argued elsewhere for their compatibility.1 Here I’ll just assume that they are compatible and explore some consequences of conjoining a particular externalist thesis about the contents of thoughts (Social Externalism) with a particular thesis about self-knowledge (First-Person Authority).
