This essay presents a philosophical and computational theory of the representation of de re, de dicto, nested, and quasi-indexical belief reports expressed in natural language. The propositional Semantic Network Processing System (SNePS) is used for representing and reasoning about these reports. In particular, quasi-indicators (indexical expressions occurring in intentional contexts and representing uses of indicators by another speaker) pose problems for natural-language representation and reasoning systems, because--unlike pure indicators--they cannot be replaced by coreferential NPs without changing the meaning of the (...) embedding sentence. Therefore, the referent of the quasi-indicator must be represented in such a way that no invalid coreferential claims are entailed. The importance of quasi-indicators is discussed, and it is shown that all four of the above categories of belief reports can be handled by a single representational technique using belief spaces containing intensional entities. Inference rules and belief-revision techniques for the system are also examined. (shrink)

One can have no prior credence whatsoever (not even zero) in a temporally indexical claim. This fact saves the principle of conditionalization from potential counterexample and undermines the Elga and Arntzenius/Dorr arguments for the thirder position and Lewis' argument for the halfer position on the Sleeping Beauty Problem, thereby supporting the double-halfer position. -/- .

John Abbruzzese has recently attempted a defense of omniscience against a series of my attacks. This affords me a welcome occasion to clarify some of the arguments, to pursue some neglected subtleties, and to re-think some important complications. In the end, however, I must insist that at least three of four crucial arguments really do show an omniscient being to be impossible. Abbruzzese sometimes misunderstands the forms of the argument themselves, and quite generally misunderstands their force.

nated discussion of the semantics of such verbs. I will call this view.

This essay offers a proposal for how to understand the idea that there is a special connection between de se attitudes and the explanation of action.

A survey of logical problems for the concept of omniscience.

What is the relationship between Frege’s puzzle and the puzzle of the de se? An increasingly influential view claims that the de se puzzle is merely an instance of Frege’s puzzle and that the idea that de se attitudes pose a distinctive theoretical challenge rests on a myth. Here we argue that this view is misguided. There are important differences between the two puzzles. First, unlike Frege puzzle cases, de se puzzle cases involve unshareable Fregean senses. Second, unlike Frege puzzle (...) cases, de se puzzle cases cannot be resolved by objective information alone. Further, there seem to be pure cases of each puzzle: instances of the de se puzzle which do not have a Fregean structure, and instances of Frege’s puzzle, which do not involve de se attitudes. We conclude that the two puzzles are fundamentally different and that the traditional theory of attitudes needs to be amended. (shrink)

De se attitudes seem to play a special role in action and cognition. This raises a challenge to the traditional way in which mental attitudes have been understood. In this chapter, we review the case for thinking that de se attitudes require special theoretical treatment and discuss various ways in which the traditional theory can be modified to accommodate de se attitudes.

This paper argues that Paul Ricoeur’s hermeneutical philosophy attempts to reopen the question of human transcendence in contemporary terms. While his conception of language as self-transcending is deeply Husserlian, Ricoeur also responds to the analytical challenge when he deploys a basic distinction in Fregean logic in order to clarify Heidegger’s phenomenology of world. Ricoeur’s commitment to a transcendental view is evident in his conception of narrative, which enables him to emphasize the role of the performative in literary reading. The meaning (...) of the self in time provides Ricoeur with a discursive basis for distinguishing his own position from that of Kant and other philosophers in the transcendental tradition. (shrink)

In recent literature in the philosophy of mind and language, one finds a variety of examples that raise serious problems for the traditional analysis of belief as a two-term relation between a believer and a proposition. My main purpose in this essay is to provide a critical test case for any theory of the propositional attitudes, and to demonstrate that this case really does present an unsolved puzzle. Chapter I defines the traditional, propositional analysis of belief, and then introduces a (...) distinction, motivated by the intuitions that underlie Kripke's arguments for direct reference, between purely qualitative and individual propositions. Beliefs typically expressed using proper names, indexicals or demonstratives appear to relate the believer to individual propositions with the entity that may be referred to as subject constituent. Chapter II presents the critical test case . In this and Chapters III-VI it is used to show that the latter sorts of beliefs are not analyzable as dyadically relating the believer to individual propositions. The case constitutes a genuine counterexample to the traditional analysis only if it is possible for a believer to believe an individual proposition with a contingent thing other than herself as a constituent; and the believer in the case is in optimum conditions for believing an individual proposition. In Chapters III, IV, and VI, I criticize views prompted by rejection of , and in Chapter V, I criticize Stalnaker's view, which rejects . Chapter VI also considers the non-traditional, triadic analyses of belief proposed by Kaplan and Richard; they fall prey to the main criticisms of Chapter V. In the Postscript, I give a comparative assessment of approaches to resolving the Two Tubes Puzzle, and I place it in historical context by pointing out the puzzle's similarities to the 'problem of sense data' . Correlatively, I indicate the bearing of Methodological Solipsism on future attempts to solve the puzzle. My conclusion is that although the puzzle remains a puzzle, it gives us reason to supplement, rather than completely abandon, the use of propositions in the analysis of thought; and I say what a supplementing solution must do to remain faithful to the intuitions of Chapter I.

The Hard Problem of the mind is addressed and it is argued that physical-phenomenal property identities have the same status as the identification of an ostended bit of physical space and the coordinates assigned the spot on a map of the terrain. It is argued, that is to say, that such identities are, or follow from, stipulations which interpret the map.

In temporal counteridenticals like ‘Ian is imagining that it is 2030 and Sally is rich’, the subject locates themself at a time other than (what they believe to be) the current time. In such reports, tense in the embedded clause can denote the time that the attitude holder imagines herself to be located at, or the time that she believes herself to be located at. I show that these two interpretations are subject to systematic constraints. The observed pattern is parallel (...) to that discovered in Pearson (in prep.) for personal counteridenticals, such as Lakoff’s famous Brigitte Bardot sentence. I propose an analysis of these findings that depends on two key assumptions: (1) there is a mechanism of ‘de nunc binding’ that encodes the ‘subjective now’ of the attitude holder; and (2) this mechanism is constrained by a principle of the grammar called ‘Condition CW’, originally proposed for personal counteridenticals in Pearson (in prep.). These findings support the view that attitudes de se and de nunc constitute a special class, not reducible to de re. They further suggest that there is a dedicated linguistic mechanism for encoding such attitudes that is subject to systematic grammatical constraints. (shrink)

It has been widely acknowledged that indexical thought poses a problem for traditional theories of mental content. However, recent work in philosophy has defied this received view and challenged its defenders not to rely on intuitions but rather to clearly articulate what the problem is supposed to be. For example, in “The Inessential Indexical”, Cappelen and Dever claim that there are no philosophically interesting or important roles played by essential indexical representations. This paper assesses the role of essential indexicality in (...) understanding the content of perception and argues that, if the perceptual experiences of different subjects can have the same phenomenology, and thus share a representational content (phenomenal content)—assumptions shared by a well-established research project, including a wide variety of theories—, then phenomenal content exhibit a particular kind of essential indexicality (perspectival). I also discuss how the argument is immune to Cappelen and Dever’s objections to the idea that the content of perceptual experiences is essentially indexical. (shrink)

De se exceptionalism is the view that de se attitudes pose a distinctive problem for traditional theories of propositional attitudes. A recent argument for de se exceptionalism attempts to prove that the distinctive problem of de se attitudes has something to do with the role of de se attitudes in explaining actions. The argument is based on a case where two subjects seem to believe and desire all the same propositions but perform different actions. This is the most promising argument (...) for de se exceptionalism in the current literature. This paper rejects the argument by proposing a novel model of action explanation, according to which agents perform what they consider to be the best actions. I will argue that the case, based on which the recent argument for de se exceptionalism is developed, is philosophically interesting. Traditional theories of propositional attitudes can accommodate the case easily. I will conclude that de se exceptionalism should be rejected. (shrink)

Inspired by Castañeda, Perry and Lewis argued that, among singular thoughts in general, thoughts about oneself ‘as oneself’ – first-personal thoughts, which Lewis aptly called de se – call for special treatment: we need to abandon one of two traditional assumptions on the contents needed to provide rationalizing explanations, their shareability or their absoluteness. Their arguments have been very influential; one might take them as establishing a new ‘effect’ – new philosophical evidence in need of being accounted for. This is (...) questioned by the skeptical arguments in recent work by Cappelen & Dever and Magidor, along lines that a few discrepant voices had already announced earlier. Skeptics content that the evidence does not really call for revising traditional theories of content. I will discuss their challenges – first and foremost, concerning action explanations – aiming to make the case that the ‘De Se effect’ is no illusion: de se attitudes require us to revise one of the two tenets of traditional views.

This is a survey of recent work on God and human freedom. A version of the "basic" argument for the incompatibility of God's omniscience and human freedom is presented. Various possible responses are developed and discussed.

Abstract Buddhist egology concurs with the Husserlian claim that the enipirical ego is ?constituted?. The Buddhist ?deconstruction? of the ego will not, however, pace Husserl, permit the pronoun ?I? to refer to a purported extra?linguistic entity. The insights here distilled from the unique mode of self?reference functional within the Vietnamese language secure for us an unmistakable confirmation of the Buddhist thesis and have profound consequences for the philosophical problems surrounding the existence and nature of the self and the existence of (...) other minds.

Frank Jackson argued, in an astronomically frequently cited paper on 'Epiphenomenal qualia '[Jackson 1982 that materialism must be mistaken. His argument is called the knowledge argument. Over the years since he published that paper, he gradually came to the conviction that the conclusion of the knowledge argument must be mistaken. Yet he long remained totally unconvinced by any of the very numerous published attempts to explain where his knowledge argument had gone astray. Eventually, Jackson did publish a diagnosis of the (...) reasons why, he now thinks, his knowledge argument against materialism fails to prove the falsity of materialism [Jackson 2005. He argues that you can block the knowledge argument against materialism - but only if you tie yourself to a dubious doctrine called representationalism. We argue that the knowledge argument fails as a refutation of either representational or nonrepresentational materialism. It does, however, furnish both materialists and dualists with a successful argument for the existence of distinctively first-person modes of acquaintance with mental states. Jackson's argument does not refute materialism: but it does bring to the surface significant features of thought and experience, which many dualists have sensed, and most materialists have missed.

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. Note: the embedded video of Peter's mistaken self-identity is urlhttp://ncs.ruhosting.nl/emar/dese.mpgavailable in .mpg here. (shrink)

Sidgwick maintains, plausibly, that the concept of a person's good is a normative one and takes for granted that it is normative for the agent's own choice and action. I argue that the normativity of a person's good must be understood in relation to concern for someone for that person's own sake. A person's good, I suggest, is what one should want for that person in so far as one cares about him, or what one should want for him for (...) his sake. I examine Sidgwick's defence of the axioms of rational prudence and argue that it is powerless to convince anyone who lacks self-concern or thinks he has no reason to care for himself. To the extent that Sidgwick is persuasive, I argue, it is because he insinuates an assumption of self-concern. Similarly, Sidgwick's defence of the axiom of rational benevolence tacitly assumes, not just impersonality, but equal concern. (shrink)
