Focusing on the 'today'/'yesterday' case, I argue that Perry is wrong in accounting for and explaining indexical belief states in terms of Kaplanian characters and in taking these states to be internal (narrow) mental states inside the subject's mind. It is shown that this view is at odds with Perry's own reliance on remembering a past day as a necessary condition for retaining a belief about it. As a better tool for explaining appropriate indexical beliefs, I offer an alternative which (...) is neo-Fregean in that it takes senses or modes of presentation as playing only a cognitive, not a semantic role. It, however, takes remembering a past day as necessary for retaining a belief about it, rather than keeping track of time as urged by Evans. I also consider unfeasible Evans's further requirement which he takes over from Frege: that in order to retain a belief about a certain past day we need to think of it now under the same mode of presentation as we did on that very day.

What is it for two people to think of an object, natural kind or other entity under the same mode of presentation (MOP)? This has seemed a particularly difficult question for advocates of the Mental Files approach, the Language of Thought, or other ‘atomistic’ theories. In this paper I propose a simple answer. I first argue that, by parallel with the synchronic intrapersonal case, the sharing of a MOP should involve a certain kind of epistemic transparency between the token thoughts (...) of the two thinkers. I then explain how shared words help bring about this transparency. Finally, I show how this account can be extended for thoughts expressed using demonstratives or indexicals. (shrink)

In “Understanding Demonstratives”, Gareth Evans bites the bullet regarding Rip van Winkle cases in cognitive dynamics: the fact that Rip sleeps for twenty years and completely loses track of time means he is unable to retain his original belief that “Today is a fine day”. In this paper, the author argues that Evans need not bite this bullet because there are resources in his account of the cognitive dynamics involved in belief retention developed in The Varieties of Reference to successfully (...) confront the challenge posed by the Rip van Winkle case. In particular, when we combine the two central elements of Evans’s cognitive dynamics – the skill of keeping track of one’s spatio-temporal location in addition to memory – it is possible to arrive at the conclusion that it is indeed possible for Rip to retain and re-express his original belief.

An influential tradition holds that thoughts are public: different thinkers share many of their thoughts, and the same applies to a single subject at different times. This ‘publicity principle’ has recently come under attack. Arguments by Mark Crimmins, Richard Heck and Brian Loar seem to show that publicity is inconsistent with the widely accepted principle that someone who is ignorant or mistaken about certain identity facts will have distinct thoughts about the relevant object—for instance, the astronomer who does not know (...) that Hesperus is Phosphorus will have two distinct thoughts Hesperus is bright and Phosphorus is bright. In this paper, I argue that publicity can be defended if we adopt a relational account on which thoughts are individuated by their mutual relations. I then go on to develop a specific relational theory—the ‘linking account’—and contrast it with other relational views. (shrink)

Many scholars are ready to accept that first person thought involves a special way w such that, for any thinker x, only x can access the first person way w of thinking about x. Standard articulations of this Frege-inspired view involve a rejection of the strict shareability of first person thought. I argue that this rejection eventually forces us to renounce an intuitively plausible characterisation of communication, and specifically, disagreement. This result invites us to explore alternative articulations which, still within (...) an overall Fregean framework, may better explain how first person thoughts reach out into a public, shareable dimension. Here I shape this possibility in terms of perspectives, i.e. ways of thinking that do not individuate concepts or thoughts. Perspectives, I submit, can serve to unproblematically accommodate basic disagreement in indexical cases and to outline the dynamic character of first person thought. (shrink)

Consider the Unshareability View, namely, the view that first person thought or self-thought—thought as typically expressed via the first person pronoun—is not shareable from subject to subject. In this article, I show that a significant number of Fregean and non-Fregean commentators of Frege have taken the Unshareability View to be the default Fregean position, rehearse Frege’s chief claims about self-thought and suggest that their combination entails the Unshareability View only on the assumption that there is a one-to-one correspondence between way (...) of thinking and thought-individuating cognitive value, outline an account of self-thought that rejects the assumption and keeps intact all of Frege’s chief claims, and respond to a number of worries to the effect that this proposal yields undesirable results from the point of view of the individuation of self-thought at the level of cognitive value.

Concerning cases involving temporal indexicals Kaplan has argued that Fregean thoughts cannot be the bearers of cognitive significance due to the alleged fact that one can think the same thought from one occasion to the next without realizing this—thus linking the issue of cognitive significance to that of belief retention. Kaplan comes up with his own version of the Fregean strategy for accounting for belief retention that does not face this kind of a problem; but he finds it deficient because (...) it leads us to implausibly deny that one who is lost in time retains the beliefs one held before this occurred. I take issue with Kaplan though in conformity with his plausible demands about belief retention and argue that a situation does not arise in which one can fail to realize that one is thinking the same thought from one occasion to the next. I also argue that thoughts are the bearers of cognitive significance as well as explanatory of belief retention. (shrink)

This paper is about first‐person thoughts—thoughts about oneself that are expressible through uses of first‐person pronouns. It is widely held that first‐person thoughts cannot be shared. My aim is to postpone rejection of the more natural view that such thoughts about oneself can be shared. I sketch an account on which such thoughts can be shared and indicate some ways in which deciding the fate of the account will depend upon further work.

In this essay I first review Kaplan’s theory of linguistic character, and then explain and motivate a concept of doxastic character. I then develop some concepts for dealing with the topic of belief retention and then, finally, discuss Rip Van Winkle. I come down on Kaplan’s side with respect to the Frege-inspired strategy, narrowly construed. But I advocate something like the Frege-inspired strategy, if it is construed more broadly. On my view it is remarkably easy to retain a belief, and (...) I think Evans is quite wrong about Rip and Kaplan. The central concept I develop, however, that of an information game, is in the spirit of much of Evans’ work. I also borrow some of his terminology. (shrink)

This paper is devoted to an examination of issues concerning the persistence and linguistic re-expression of indexical singular belief. I discuss two approaches to the topic: the directly referential approach, which I take as best represented in Kaplan's views, and the neo-Fregean approach, which I take as best represented in Gareth Evans's views. The upshot of my discussion is twofold. On the one hand, I argue that both Kaplan's account and Evans's account are on the whole defective. On the other, (...) I claim that a broadly Fregean account is still to be preferred, since by positing semantically efficacious modes of presentation it is clearly better equipped to deal with the phenomena in the area. In particular, I argue that the notion of a memory-based mode of presentation of an object (a spatio-temporal particular, a region in space, a period of time, etc.), as introduced by Christopher Peacocke, turns out to be indispensable to account for the persistence and re-expression of intentional mental states over time.
