The moral belief problem is that of reconciling expressivism in ethics with both minimalism in the philosophy of language and the syntactic discipline of moral sentences. It is argued that the problem can be solved by distinguishing minimal and robust senses of belief, where a minimal belief is any state of mind expressed by sincere assertoric use of a syntactically disciplined sentence and a robust belief is a minimal belief with some additional property R. Two attempts to specify R are discussed, both based on the thought that beliefs are states that aim at truth. According to the first, robust beliefs are criticisable to the extent that their content fails to match the state of the world. This sense fails to distinguish robust beliefs from minimal beliefs. According to the second, robust beliefs function to have their content match the state of the world. This sense succeeds in distinguishing robust beliefs from minimal beliefs. The conclusion is that the debate concerning the cognitive status of moral convictions needs to address the issue of the function of moral convictions. Evolutionary theorising may be relevant, but will not be decisive, in answering this question.

A widely accepted view in the discussion of personal identity is that the notion of psychological continuity expresses a one–many or many–one relation. This belief is unfounded. A notion of psychological continuity expresses a one–many or many–one relation only if it includes, as a constituent, psychological properties whose relation with their bearers is one–many or many–one; but the relation between an indexical psychological state and its bearer when first tokened is not a one–many or many–one relation. It follows that not all types of psychological continuity may take a one–many or many–one form. This conclusion casts doubt on the Lockean approach to the issue, by showing that the notion of psychological continuity Lockeans rely on may not be available.

According to an attractive account of belief, our beliefs have centered content. According to an attractive account of communication, we utter sentences to express our beliefs and share them with each other. However, the two accounts are in conflict. We have to either change our understanding of belief or modify our theory of communication. In this paper, I explore the consequences of holding on to the claim that beliefs have centered content. If we do in fact express the centered content of our beliefs, the content of the belief the hearer acquires cannot in general be identical to the content the speaker expresses. I sketch an alternative account of communication, the Recentering model, that accepts this consequence and explains how the expressed and the acquired content are related.

In this paper, I argue, contra Perry, that the existence of locating beliefs does not require the abandonment of the analysis of belief as a relation between subjects and propositions. I argue that what the "problem of the essential indexical" reveals is that a complete explanation of behaviour requires both an explanation of the type of behaviour the agent engaged in and an explanation of why she engaged in it in the circumstances that she did. And I develop an account of belief which encompasses both explanatory roles and which still treats belief as a two-place relation between subjects and propositions.

Indexical beliefs pose a special problem for standard theories of Bayesian updating. Sometimes we are uncertain about our location in time and space. How are we to update our beliefs in situations like these? In a stepwise fashion, I develop a constraint on the dynamics of indexical belief. As an application, the suggested constraint is brought to bear on the Sleeping Beauty problem.

This paper is about the dispositional difference that demonstrative and indexical beliefs make. More specifically, it is about the dispositional difference between my believing that NN is P (where I am NN) and my believing that I, myself, am P. Identifying a dispositional difference in this kind of case is especially challenging because those beliefs have the very same truth conditions. My question is this: how can a difference in belief that makes no difference to one’s conception of the world nonetheless make a difference to one’s actions and reactions? I will argue that the dispositions associated with indexical beliefs are best of thought of as likebelief revision policies: they make no difference to the content of our conception of the world, but they govern how we canchange and revise that conception, and in so doing contribute to making rational action possible. Seeing all of this will help usto better understand how it is that first-person indexical beliefs manifest self-consciousness.

Some time ago, John Perry argued that the content of an indexical belief, that is, a belief expressible with a sentence containing an indexical or demonstrative, cannot be a proposition. I consider several of his arguments for this view, and show that they can be extended to show that belief expressible with other non-indexical expressions such as natural kind terms and proper names presents the very same problem for the traditional picture. I then suggest that if indexical belief has any special status, this is not because it has a special kind of content, but rather because action is impossible if agents do not have indexical belief.
