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.

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)

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.

Self-locating attitudes and assertions provide a challenge to the received view of mental and linguistic intentionality. In this paper I try to show that the best way to meet this challenge is to adopt relativistic, centred possible worlds accounts for both belief and communication. First, I argue that self-locating beliefs support a centred account of belief. Second, I argue that self-locating utterances support a complementary centred account of communication. Together, these two claims motivate a unified centred conception of belief and (...) communication. (shrink)

Inspired by Castañeda (1966, 1968), Perry (1979) and Lewis (1979) showed that a specific variety of singular thoughts, thoughts about oneself “as oneself” – de se thoughts, as Lewis called them – raise special issues, and they advanced rival accounts. Their suggestive examples raise the problem of de se thought – to wit, how to characterize it so as to give an accurate account of the data, tracing its relations to singular thoughts in general. After rehearsing the main tenets of (...) two contrasting accounts – a Lewisian one and a Perrian one – in the first section of this paper, in the second I will present a proposal of my own, which is a specific elaboration of the Perrian account. In the first section I will indicate some weaknesses of Perry’s presentation of his view; the proposal I will articulate in the second overcomes them. I will conclude with a brief discussion of reasons for preferring one or another account, in particular regarding the issue of the communication of de se thoughts. (shrink)

Focusing on predicates of taste, this paper puts forward a novel version of relativism, motivated by a recently discussed phenomenon: perspectival plurality. After showing that the phenomenon is problematic for at least some versions of relativism and discussing several possible answers on behalf of the relativist, I put forward my own version. The main feature of the proposal is the introduction in the index not of a single parameter for perspectives, but of a (possibly infinite) sequence of such parameters. In (...) the last part of the paper, I defend the view from three objections. (shrink)

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. 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 expressed and acquired content are related. (shrink)

It seems plausible that successfully communicating with our peers requires entertaining the same thoughts as they do. We argue that this view is incompatible with other, independently plausible principles of thought individuation. Our argument is based on a puzzle inspired by the Kripkean story of Peter and Paderewski: having developed several variations of the original story, we conclude that understanding and communication cannot be modeled as a process of thought transfer between speaker and hearer. While we are not the first (...) to reach this conclusion, the significance of our argument lies in the fact that it only relies on widely accepted premises, without depending on any especially controversial theory of mental and linguistic content. We conclude by drawing out the implications of that conclusion: if communication and understanding do not require thought identity, then one important motivation for the postulation of inter-personally shared thoughts is undercut. (shrink)

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)

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)

My responses to seven critical reviews of my book *Mental Files* published in a special issue of the journal Disputatio, edited by F. Salis. The reviewers are: Keith Hall, David Papineau, Annalisa Coliva and Delia Belleri, Peter Pagin, Thea Goodsell, Krista Lawlor and Manuel Garcia-Carpintero.

I argue that Frege Problems in thought are best modeled using graph-theoretic machinery; and that these problems can arise even when subjects associate all the same qualitative properties to the object they’re thinking of twice. I compare the proposed treatment to similar ideas by Heck, Ninan, Recanati, Kamp and Asher, Fodor, and others.

Traditional procedures for rational updating fail when it comes to self-locating opinions, such as your credences about where you are and what time it is. This paper develops an updating procedure for rational agents with self-locating beliefs. In short, I argue that rational updating can be factored into two steps. The first step uses information you recall from your previous self to form a hypothetical credence distribution, and the second step changes this hypothetical distribution to reflect information you have genuinely (...) learned as time has passed. While the second step resembles traditional procedures of updating by conditionalization, the first is best understood by analogy to traditional models of how agents transmit self-locating opinions through ordinary interpersonal communication.

According to one tradition in the philosophy of language and mind, the content of a psychological attitude can be characterized by a set of possibilities. On the classic version of this account, advocated by Hintikka (1962) and Stalnaker (1984) among others, the possibilities in question are possible worlds, ways the universe might be. Lewis (1979, 1983a) proposed an alternative to this account, according to which the possibilities in question are possible individuals or centered worlds, ways an individual might be. The (...) motivation for the centered worlds theory has primarily to do with self-locating – or de se – attitudes. The focus of this paper is on the less-discussed question of how other-locating – or de re – attitudes ought to be treated within this framework. Most advocates of what we might call the modal approach to attitudes, Stalnaker and Lewis included, offer some kind of descriptivist solution to the well-known problems that other-locating attitudes raise. There are intramural differences between Stalnaker, Lewis, and other modal theorists (e.g. two-dimensionalists) on a number of issues: on the precise nature of the descriptivism involved, how attitude content relates to the asserted content of the sentences we utter, and on the proper semantic treatment of attitude reports. I pass over these differences to focus on a problem common to these various approaches: all face a problem when it comes to characterizing the contents of counterfactual attitudes like imagining, dreaming, and wishing.

In his book Mental Files , Francois Recanati develops a theory of mind and language based on the idea that Fregean senses should be identified with ‘mental files’, mental representations whose primary function is to store information about objects. I discuss three aspects of Recanati’s book. The first concerns his use of acquaintance relations in individuating mental files, and what this means for ‘file dynamics’. The second concerns his comments on a theory that I have elsewhere advocated, the ‘sequenced worlds’ (...) or ‘multi-centered worlds’ theory. The third concerns how the mental file approach handles non-doxastic attitudes like imagining. (shrink)

This paper concerns two points of intersection between de se attitudes and the study of natural language: attitude ascription and communication. I first survey some recent work on the semantics of de se attitude ascriptions, with particular attention to ascriptions that are true only if the subject of the ascription has the appropriate de se attitude. I then examine – and attempt to solve – some problems concerning the role of de se attitudes in linguistic communication.

This paper argues that several leading theories of subjunctive conditionals are incompatible with ordinary intuitions about what credences we ought to have in subjunctive conditionals. In short, our theory of subjunctives should intuitively display semantic humility, i.e. our semantic theory should deliver the truth conditions of sentences without pronouncing on whether those conditions actually obtain. In addition to describing intuitions about subjunctive conditionals, I argue that we can derive these ordinary intuitions from justified premises, and I answer a possible worry (...) for my derivation by refuting a subjunctive triviality result modeled on (Lewis 1976). I conclude that the debate over the correct theory of subjunctive conditionals requires settling meta-philosophical questions about the relative value of various virtues of first-order theories of subjunctive conditionals.

This paper explores the possibility of developing a hybrid version of dispositional theories of aesthetic values. On such a theory, uses of aesthetic predicates express relational second-order dispositional properties. If the theory is not absolutist, it allows for the relativity of aesthetic values. But it may be objected to on the grounds that it fails to explain disagreement among subjects who are not disposed alike. This paper explores the possibility of adapting recent proposals of hybrid expressivist theories for moral predicates (...) to the case of aesthetic predicates. Hybrid expressivist theories make no explicit commitment about the kind of property expressed by the predicate, but make explicit commitments to implicated (or presupposed)expressive content. It is argued that dispositionalism about the properties expressed by aesthetic predicates, combined with expressive implicatures (or presuppositions), can account for aesthetic disagreements even in cases where subjects are not relevantly alike. (shrink)

I distinguish two notions of agreement in belief: believing the same content versus having beliefs that necessarily coincide/diverge in normative status. The second notion of agreement,, is clearly significant for the communication of beliefs amongst thinkers. Thus there would seem to be some prima facie advantage to choosing the conception of content operative in in such a way that the normative status of beliefs supervenes on their content, and this seems to be the prevailing assumption of many semanticists. I shall (...) argue that de se beliefs and assertions provide a motivation to depart from this assumption, and so do beliefs and assertions concerning what is epistemically possible. I conclude by offering two models of assertoric communication that are compatible with the abandonment of the assumption, and suggesting schematically that each model applies to different cases. (shrink)

In the pair of articles of which this is the second, I present a set of problems and philosophical proposals that have in recent years been associated with the term “relativism”. These problems are related to the question of how we should represent thought and speech about certain topics. The main issue is whether we should model such mental states or linguistic acts as involving representational contents that are absolutely correct or incorrect, or whether, alternatively, their correctness should be thought (...) of as varying with some (more or less surprising) factor. In the first article, “Relativism 1: Representational Content”, I discussed the general issue of relativism about representational content. I argued for the conciliatory view that both relativist and absoutist conceptions of representational content can be legitimate. In the present continuation, I look in more detail at a special case of the general issue, namely the question of whether semantic contents, i.e. the contents assigned to linguistic utterances in the semantics of natural language, should be construed in an absolutist or in a relativist way. (shrink)

Some philosophers, for example David Lewis, have argued for the need to introduce de se contents or centered contents, i.e. contents of thought and speech the correctness of believing which depends not only on the possible world one inhabits, but also on the location one occupies. Independently, philosophers like Robert Stalnaker (and also David Lewis) have developed the conversational score model of linguistic communication. This conversational model usually relies on a more standard conception of content according to which the correctness (...) of believing a content depends merely on the possible world one occupies. The aim of this paper is to develop a modified conversational score model that operates with centered contents. I begin by explaining how in principle centered contents can figure in the transfer of information from one thinker to another. Here I distinguish the local portability approach from the portable surrogate approach. Then I explain how these modes of information transfer can be exploited in a stalnakerian conversational model involving centered contents, proposing a modified update rule for assertion. (shrink)

In this paper, I argue that, contrary to Robert Stalnaker’s highly influential account of linguistic communication, successful communication does not depend on a common ground between speaker and hearer. The problem for Stalnaker’s account manifests itself in communicative situations that represent both Lingens cases, i.e., cases involving egocentric beliefs, and Frege cases, i.e., cases involving identity confusions. I describe two hypothetical cases that involve successful communication, but in which no common ground of the kind required by Stalnaker’s account is available. (...) I therefore propose an alternative account of communication that is based on epistemic two-dimensionalism. This account maintains that communication requires the transfer of a thought content from speaker to hearer. By holding that this shared content often constitutes common ground, it preserves much of the appeal of Stalnaker’s account. However, my account allows for cases in which the shared thought content does not figure in common ground. (shrink)

It has long been known that the popular account of egocentric thoughts developed by David Lewis is in conflict with a natural account of communication, according to which successful communication requires the transmission of a thought content from speaker to hearer. In this paper, I discuss a number of proposed attempts to reconcile these two accounts of egocentric thought and communication. Each of them postulates two kinds of mental content, where one is egocentric, and the other is transmitted from speaker (...) to hearer in communication. I argue that Ninan’s account, which involves multi-centered contents, and Kölbel’s and Moss’s accounts, which postulate centered and uncentered proxy contents, respectively, are unsatisfactory. Therefore, I propose a two-dimensionalist account, according to which egocentric thoughts are represented by primary intensions, while the thoughts shared by speaker and hearer in cases of successful communication are represented by secondary intensions. Finally, I argue that aside from being able to reconcile Lewis’s account of egocentric thoughts with the natural account of communication, two-dimensionalism also provides the means for modeling agreement and disagreement.

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)

“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)

Recent descendants of David Lewis, such as Stephen Torre, Dilip Ninan, and Dirk Kindermann have utilized multi-centered propositions, which are roughly sets of possible worlds centered on a sequence of individuals, to characterize the content of attitudes. In an attempt to explain counterfactual attitudes such as wishing and imagining, Ninan (2012, 2013) developed a more fine-grained characterization of multi-centered propositions than others in the multi-centered camp. While Ninan provides a systematic explanation of the nature of de se attitudes (attitudes one (...) expresses with first-person pronouns like ‘I’ or ‘me’), the nature of other types of indexical attitudes (attitudes one expresses with indexical terms like ‘you,’ ‘today,’ ‘now,’) is not explored. This paper does two things. First, it demonstrates how we can account for indexical attitudes within Ninan’s framework. This, however, has the consequence of generating propositions of limited accessibility of sorts, which in turn conflict with a received and simple model of linguistic communication. According to this simple model, successful communication consists of the transmission of mental content from speaker to hearer. Second, in light of this conflict, the paper proposes an adjustment to Ninan’s theory in order to avoid commitment to propositions of limited accessibility, and thus preserve the shareability of attitudinal content from speaker to hearer. (shrink)

It has recently been proposed that the framework of semantic relativism be put to use to describe mental content, as deployed in some of the fundamental operations of the mind. This programme has inspired in particular a novel strategy of accounting for the essential egocentricity of first-personal or de se thoughts in relativist terms, with the advantage of dispensing with a notion of self-representation. This paper is a critical discussion of this strategy. While it is based on a plausible appeal (...) to cognitive economy, the relativist theory does not fully account for the epistemic profile that distinguishes de se thinking, as some of its proponents hope to do. A deeper worry concerns the reliance of the theory on a primitive notion of “centre” that hasn’t yet received enough critical attention, and is ambiguous between a thin and a rich reading. I argue that while the rich reading is required if the relativist analysis of the de se is to achieve its most ambitious aims, it also deprives the theory of much of its explanatory power. (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.

Adopting a dispositional theory of value promises to deliver a lot of theoretical goodies. One recurring problem for dispositional theories of value, though, is a problem about nonconvergence. If being a value is being disposed to elicit response R in us, what should we say if it turns out that not everybody is disposed to have R to the same things? One horn of the problem here is a danger of the view collapsing into an error theory—of it turning out, (...) on account of the diversity of agents' relevant dispositions, that nothing is really a value, since nothing is disposed to elicit R in everybody. Alternatively, there is a danger of an objectionable fragmentation of value, according to which there is no such thing as a value simpliciter, but only valuesme and valuesyou, valuesus and valuesthem. I advocate a de se relativist version of a dispositional theory of value. If we go for this sort of de-se-ified dispositional theory, we get to keep our theoretical goodies, but we avoid the problem of nonconvergence that leads to a danger of either collapse into an error theory, or else talking-past, and a loss of common subject matter.

In this paper I argue that propositionalism is what generates a tension between referentialism and harmony. Harmony can be preserved if we replace propositionalism by centred referentialism, according to which referential thoughts and utterances about an object have descriptive contents that must be evaluated relative to a world centred on that object at the relevant time. By disentangling truth-conditions and contents, this move allows us to dissolve the tension between referentialism and descriptivism. The view that emerges has three main components: (...) the truth-conditions of a referential utterance or thought involves its referent ; its reference is determined by causal relations of acquaintance in the context of use ; and its cognitive value is fully explained by associated descriptions or truth-conditional contents.

The topic of the paper is at the intersection of recent debates on de se thought and phenomenal intentionality. An interesting problem for phenomenal intentionality is the question of how to account for the intentional properties of de se thought-contents---i.e., thoughts about oneself as oneself. Here, I aim to describe and consider the significance of a phenomenological perspective on self-consciousness in its application to de se thought. I argue that having de se thoughts can be explained in terms of the (...) ways that subjects consciously attend to themselves in experiences of thinking. Therefore, a strong form of first-person persectivalness, in which the subject is capable of self-directed control of the focus of conscious attention, is required for de se thought. But no constraints on the semantic content of such thoughts are required. The outcome of the question therefore bears importantly on both on the problem of self-reflexive self-reference and the wider problem of self-consciousness. My model suggests phenomenologically-derived conceptual constraints for the extension of minimal, background forms of self-awareness to robust, cognitive forms of self-awareness that have been of interest in recent empirical studies on self-consciousness. The framework therefore provides a way of operationalizing the concept of self-reflexive consciousness by deploying widely deployed notions from the empirical literature such as attention and minimal phenomenal selfhood, enabling a framework for empirically falsifiable hypotheses about the neural mechanisms underlying the structure of self-consciousness.

What role, if any, should centered possible worlds play in characterizing the attitudes? Lewis :513–543, 1979) argued that, in order to account for the phenomena of self-location :474–497, 1977, Noûs 13:3–21, 1979), the contents of the attitudes should be taken to be centered propositions. Stalnaker Assertion: New philosophical essays, Oxford University Press, Oxford, 2011, Context, Oxford University Press, Oxford, 2014), however, has argued that while centered worlds are needed to characterize e.g. belief states, the contents of such states should be (...) understood as ordinary, uncentered propositions. But Stalnaker does not, as is common, provide a semantics of attitude ascriptions based on the models he develops of the attitudinal states themselves. This paper begins to explore the prospects for doing so. It argues that a simple but well-motivated approach does not yield the principles of knowledge and belief Stalnaker endorses; and that a modification which does brings with it worries of its own surrounding communication and learnability. A technical appendix contains novel and pertinent results in doxastic/epistemic logic. (shrink)

Over the past few years, the tree model of time has been widely employed to deal with issues concerning the semantics of tensed discourse. The thought that has motivated its adoption is that the most plausible way to make sense of indeterminism is to conceive of future possibilities as branches that depart from a common trunk, constituted by the past and the present. However, the thought still needs to be further articulated and defended, and several important questions remain open, such (...) as the question of how actuality can be understood and formally represented in a branching framework. The present volume is intended to be a 360 degree reflection on the tree model. The contributions is gathers concern the model and its alternatives, both from a semantic and from a metaphysical point of view. ​. (shrink)

According to a widespread picture due to Kaplan, there are two levels of semantic value: character and content. Character is determined by the grammar, and it determines content with respect to context. In this chapter Recanati criticizes that picture on several grounds. He shows that we need more than two levels, and rejects the determination thesis: that linguistic meaning as determined by grammar determines content. Grammatical meaning does not determine assertoric content, he argues, but merely constrains it — speaker’s meaning (...) necessarily comes into play. On the alternative picture he offers, there are four basic levels, only one of which is determined by the grammar. Pragmatics is what enables the transition from each level to the next. (shrink)

Two-dimensional (2D) semantics is a formal framework that is used to characterize the meaning of certain linguistic expressions and the entailment relations among sentences containing them. 2D semantics has also been applied to thought contents. In contrast with standard possible worlds semantics, 2D semantics assigns extensions and truth-values to expressions relative to two possible world parameters, rather than just one. So a 2D semantic framework provides finer-grained semantic values than those available within standard possible world semantics, while using the same (...) basic model-theoretic resources. The 2D framework itself is just a formal tool. To develop a semantic theory for someone’s language, a proponent of 2D semantics must do three things: (i) explain what exactly the two possible world parameters represent, (ii) explain the rules for assigning 2D semantic values to a person’s words and sentences, and (iii) explain how 2D semantic values help in understanding the meanings of the person’s words and sentences.

A fairly simple theory of the semantics of tense is obtained by combining three claims: (i) for any time t, a present-tense sentence `p' is either true or false at t; (ii) for any time t0 earlier than t, the future-tense sentence `It will be the case that p at t' is true at t0 if `p' is true at t, false otherwise; (iii) for any time t0 later than t, the past-tense sentence `It was the case that p at (...) t' is true at t0 if `p' is true at t, false otherwise. This theory, which has been called the theory of timeless truth, is often dismissed on the basis of its alleged incapacity to comply with indeterminism. Here, instead, it will be suggested that there is no reason to be dismissive. Section 1 provides some elucidations about the theory. Sections 2 and 3 explain how a foregone objection to it can be resisted. Sections 4 and 5 show that there is a plausible sense in which (i)-(iii) are compatible with indeterminism. Sections 6 and 7 dispel some misunderstandings that may lead to think that indeterminism is not vindicated in some important sense other than that outlined. (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)

Castañeda, Perry and Lewis argued in the 1960’s and 1970’s that thoughts about oneself “as oneself” – de se thoughts – require special treatment, and advanced different accounts. In this paper I discuss Ernest Sosa’s approach to these matters. I first present his approach to singular or de re thought in general in the first section. In the second, I introduce the data that need to be explained, Perry’s and Lewis’s proposals, and Sosa’s own account, in relation to Perry’s, Lewis’s, (...) and his own views on de re thought. In the third section I present the account I prefer – a “token-reflexive” version of Perry’s original account that Perry himself came to adopt in reaction to Stalnaker’s criticisms. In the final section I take up Recanati’s recent arguments, from a viewpoint on de se thought very similar to Sosa’s, to the effect that such an account is in a good position to explain the phenomenon of immunity to error through misidentification. I argue there that that is not the case, and I conclude by suggesting that the token-reflexive account fits better both with the data and with Sosa’s Fregean take on de re thought in general. (shrink)
