A survey of logical problems for the concept of omniscience.

Percus & Sauerland (2003) use quantified belief reports of the form 'Only Peter thinks he's...' to argue for dedicated de se LFs. The argument is targeted against any reductionist account that sees de se as merely a particular subtype of de re, viz. a de re belief about oneself from a first person perspective, requiring nothing but an account of de re attitudes. My acquaintance resolution framework is an attempt at just such a reduction and in this paper I extend (...) that theory with a projection mechanism to allow local accommodation of acquaintance relations. With this extension we can account for their data, as well as for some related data involving quantified belief reports familiar from arguments in the de se literature.

Recent literature in the Philosophy of Language has focused on a variety of puzzles about de se belief--belief about oneself formed by the use of the indexical 'I' or the reflexive pronoun 'she herself'. These puzzle cases suggest that de se belief cannot be represented in the traditional way as a two-place relation between an individual and a proposition. Nevertheless, there are some versions of this traditional analysis that have not been fully discussed in the literature. ;In this dissertation I (...) examine a number of proposals for analyzing de se belief, and show how many of these entail privileged access for the agents of self-attributed belief. Privileged access for an agent takes the form of either a proposition or a belief that only the agent can entertain. Privileged access emerges as a consequence of two-place relations of belief between believers and propositions when the proposition is construed as a first-person proposition, a first-person propositional guise, an individual essence, or a Fregean 'I' thought. In all these cases I argue that privileged access for an agent leads to counter-intuitive consequences about sentence meaning and belief content. For this reason I investigate ways to avoid privileged access altogether. I conclude that the most viable alternatives are three-place relations of belief. (shrink)

[1] To know who one is, and also know whether one's experiences really belong to oneself, do not normally present any problem. It nevertheless happens that people do not recognise themselves as they walk by a mirror or do not understand that they fit some particular description. But there are situations in which it really seems impossible to be wrong about oneself. Of that, Ludwig Wittgenstein once wrote: " It is possible that, say in an accident, I should feel pain (...) in my arm, see a broken arm at my side, and think it is mine, when really it is my neighbour's. And I could, looking into a mirror, mistake a bump on his forehead for one on mine. On the other hand there is no question of recognising a person when I say I have toothache.... it is as impossible that in making the statement "I have toothache" I should have mistaken another person for myself, as it is to moan with pain by mistake, having mistaken someone else for me. " In the passage in which this remark is found, Wittgenstein distinguishes between two kinds of use of "I". The first use, as object, as in "I have broken my arm" or "The wind is blowing in my hair", he holds, involves the recognition of a particular person, and there is the possibility of error as concerns the identity of the person. In the other use, as subject, as in "I think it will rain" or "I am trying to lift my arm", no person is recognised. No mistake can be made about who the subject is. (shrink)

Technical criticism of Jacob Ross's "Sleeping Beauty, Countable Additivity and Rational Dilemmas" and Double Halfing.

This critical review of John Perry’s recent compilation of his work (Perry (1993) is mainly devoted to surveying the path leading towards a certain rapprochement between philosophers with Fregean inclinations and philosophers attracted by the picture of thought and meaning brought out by Direct Reference theorists like Donnellan, Kaplan, Kripke, Putnam, and, of course, Perry himself, by taking advantage of the suggestions in the postscripts to very well-known and deservedly influential articles.

Response to Dokic's contribution in the proceedings of the Granada workshop.

How should our beliefs change over time? Much has been written about how our beliefs should change in the light of new evidence. But that is not the question I’m asking. Sometimes our beliefs change without new evidence. I previously believed it was Sunday. I now believe it’s Monday. In this paper I discuss the implications of such beliefs for philosophy of language. I will argue that we need to allow for ‘dynamic’ beliefs, that we need new norms of belief (...) change to model how they function, and that this gives Perry’s (1977) two tier account the advantage over Lewis’s (1979) theory -/- .

In English, discourse reference to time involves grammatical tenses interpreted as temporal anaphors. Recently, it has been argued that conditionals involve modal discourse anaphora expressed by a parallel grammatical system of anaphoric modals. Based on evidence from Kalaallisut, this paper argues that temporal and modal anaphora can be just as precise in a language that does not have either grammatical category. Instead, temporal anaphora directly targets eventualities of verbs, without mediating tenses, while modal anaphora involves anaphoric moods and/or attitudinal verbs.

Parodic earlier draft of "Sleeping Beauty: why violations of probability laws are `Deal' breakers".

This paper presents a novel semantic analysis of unit names and gradable adjectives, inspired by measurement theory (Krantz et al 1971). Based on measurement theory's typology of measures, I claim that different predicates are associated with different types of measures whose special characteristics, together with features of the relations denoted by unit names, explain the puzzling limited distribution of measure phrases.
