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)

There is currently disagreement about whether the phenomenon of first-person, or de se, thought motivates a move towards special kinds of contents. Some take the conclusion that traditional propositions are unable to serve as the content of de se belief to be old news, successfully argued for in a number of influential works several decades ago.1 Recently, some philosophers have challenged the view that there exist uniquely de se contents, claiming that most of the philosophical community has been under the (...) grip of an attractive but unmotivated myth.2 At the very least, this latter group has brought into question the arguments in favor of positing special kinds of content for de se belief; I think they have successfully shown that these arguments are not as conclusive, or fully articulated, as many have taken them to be. In this paper I will address these challenges directly and I will present and defend an argument for the conclusion that the phenomenon of de se thought does indeed motivate the move to a special kind of content, content that is uniquely de se. First, I characterize a notion of de se belief that is neutral with respect to friends and foes of uniquely de se content. I then argue for a determination thesis relating de se belief to belief content: that there is no difference in de se belief without a difference in belief content. I argue that various proposals for rejecting this determination thesis are unsuccessful. In the last part of the paper, I employ this determination thesis to argue for the existence of a type of belief content that is uniquely de se. (shrink)

What characterizes indexical thinking is the fact that the modes of presentation through which one thinks of objects are context-bound and perspectival. Such modes of presentation, I claim, are mental files presupposing that we stand in certain relations to the reference : the role of the file is to store information one can gain in virtue of standing in that relation to the object. This raises the communication problem, first raised by Frege : if indexical thoughts are context-bound and relation-based, (...) how is it possible to communicate them to those who are not in the same context and do not stand in the right relations to the object? Following Frege, I argue that the solution comes from an important distinction between linguistic and psychological modes of presentation. Psychological modes of presentation are mental files. They are perspectival and context-bound. But linguistic modes of presentation are fixed by the conventions of the language and they are shared by the language users. They are public and serve to coordinate mental files in communication by constraining them to contain the piece of information they encode. In this way communication takes place even though the indexical thoughts entertained by the speaker are, in some sense, private and cannot be shared by the audience. (shrink)

We argue that there are names with de se contents and that they are theoretically fruitful. De se names serve to challenge intuitive and otherwise plausible orthodoxies such as Stalnaker's view of communication and Bayesian views of belief update. These implications are also significant for those already sympathetic to the irreducibility of de se content.

This chapter provides a critical overview of various influential accounts of de se attitudes including those proposed by Frege, Lewis and Perry. It also addresses the charge that there is nothing distinctive about de se attitudes. The second half outlines a widely accepted and influential model of communication and various complications that arise in applying this model to the communication of de se thoughts. The final section provides an overview of the papers in this volume.

In their book Relativism, Maria Baghramian and Annalisa Coliva (B&C; 2020) offer a panoramic view of various forms of relativism and their history. They mak.

Relativism entails that sentences like ‘Liquorice is tasty’ are used to assert relativistic propositions—that is, propositions whose truth-value is relative to a taste standard. I will defend this view against two objections. According to the first objection, relativism is incompatible with a Stalnakerian account of assertion. I will show that this objection fails because Stalnakerian assertions are proposals rather than attempts to update the common ground. According to the second objection, relativism problematically predicts that we can correctly assess beliefs as (...) false but faultless. I will show that it doesn't. Such assessments come out as incorrect because correct relativistic assertion requires the absence of a presupposition of non-commonality. (shrink)

In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...) (1958) thesis that the predictive power of a scientific theory is directly proportional to its explanatory potential, and vice versa. (shrink)

In recent years there has been a heated debate on how to accommodate John Perry's observations about the essentiality of indexicality into our models of linguistic communication. This article is an attempt at providing a new perspective on this issue. I argue that we should jettison two elements taken for granted by the views I present, and criticize, here: no centring, uncentring, recentring and multicentring. These elements are: (1) taking the asserted content to be a part of the communication process (...) and (2) assumptions that the indexical belief of the speaker, when successfully communicated, must be acquired by the hearer as indexical, too. The theory of indexical communication that I propose here is laid out in the mental files framework and devoid of the two aforementioned elements. (shrink)

ABSTRACT. The received picture of linguistic communication understands communication as the transmission of information from speaker's head to hearer's head. This picture is in conflict with the attractive Lewisian view of belief as self-location, which is motivated by de se attitudes – first-personal attitudes about oneself – as well as attitudes about subjective matters such as personal taste. In this paper, I provide a solution to the conflict that reconciles these views. I argue for an account of mental attitudes and (...) communication on which mental content and speech act content is understood as sets of multicentered worlds – roughly, possible worlds ‘centered’ on a sequence of individuals at a time. I develop a Stalnakerian model of communication based on multicentered worlds content, and I provide a suitable semantics for personal pronouns and predicates of personal taste. The resulting picture is one on which the point of conversation is the coordination of individual perspectives. (shrink)

It was pointed out, first by Robert Stalnaker, then also by Andy Egan, that David Lewis’s model of centered-worlds contents has undesired consequences for communication of de se contents. The recent years have seen a number of attempts to save the model by amending it to handle de se communication. Proposals include the appeal to sequences of individuals in the centers, to ersatz classical propositions, and to operations of “re-centering”. The authors are Dilip Ninan and Stephan Torre, Sarah Moss and (...) Max Kölbel, and Alan Gibbard and Clas Weber. The present paper discusses these attempts. The conclusion is that they fail.

It seems uncontroversial that Dalton wrongly believed that atoms are indivisible. However, the correct analysis of Dalton’s belief and the way it relates to contemporary beliefs about atoms is, on closer inspection, far from straightforward. In this paper, I introduce four features that any candidate analysis is plausibly bound to respect. I argue that theories that individuate concepts at the level of understanding are doomed to fail in this endeavor. I formally sketch an alternative and suggest that cases such as (...) the one presented provide support for the claim that the genuine source for concept individuation is public sharable thought.

The prevailing theoretical framework for theorising about representation construes all representation as involving objective representational contents. This classic framework has tended to drive philosophers either to claim that evaluative judgements are representations and therefore objective, or else to claim that evaluative judgements are not really representations, because they are not objective. However, a more general, already well-explored framework is available, which will allow theorists to treat evaluative judgements as full-fledged representations while leaving open whether they are objective. Such a more (...) general conception of representational content is exemplified, e.g. by Lewis's ‘centred contents’ and Gibbard's framework of ‘contents of judgement’, thus it is not new. I shall start in §1 by introducing the more general framework of perspectival contents and then illustrate in §2 how awareness of it can help expose the fallaciousness of certain widely used forms of argumentation in metaethics.

“I”‐thought is often taken to have a special cognitive significance, with “I” symbolising a subjective way of thinking about oneself that is inapt for communication. In this paper I argue that the way one thinks of oneself in “I”‐thought is immaterial to the meaning of “I,” for in general the psychological role associated with a referential expression is separable from its meaning. With respect to “I,” I suggest that its meaning consists in an interpersonal way of fixing its reference in (...) a context, which is accessible to the speaker and the hearer. Consequently, “I” would have a dual cognitive significance. (shrink)
