I present a concrete DRT-based syntax and semantics for the representation of mental states in the style of Kamp. This system is closely related to Recanati’s Mental Files framework, but adds a crucial distinction between anchors, the analogues of mental files, and attitudes like belief, desire and imagination. Attitudes are represented as separate compartments that can be referentially dependent on anchors. I show how the added distinctions help defend the useful notion of an acquaintance-based mental file against Ninan’s :368–377 2015) (...) recent challenge involving counterfactual de re attitudes.

In a series of recent works, Kit Fine, 605–631, 2003, 2007) has sketched a novel solution to Frege’s puzzle. Radically departing from previous solutions, Fine argues that Frege’s puzzle forces us to reject compositionality. In this paper we first provide an explicit formalization of the relational semantics for first-order logic suggested, but only briefly sketched, by Fine. We then show why the relational semantics alone is technically inadequate, forcing Fine to enrich the syntax with a coordination schema. Given this enrichment, (...) we argue, that that the semantics is compositional. We then examine the deep consequences of this result for Fine’s proposed solution to Frege’s puzzle. We argue that Fine has mis-diagnosed his own solution–his attempted solution does not deny compositionality. The correct characterization of Fine’s solution fits him more comfortably among familiar solutions to the puzzle. (shrink)

This paper presents novel data regarding the logophoric pronoun in Ewe. We show that, contrary to what had been assumed in the absence of the necessary fieldwork, Ewe logophors are not obligatorily interpreted de se. We discuss the prima facie rather surprising nature of this discovery given the assumptions that de se construals arise via binding of the pronoun by an abstraction operator in the left periphery of the clausal complement of an attitude predicate, and that logophors are elements that (...) are obligatorily bound by such abstractors. We show that this approach can be reconciled with these facts given the additional assumption that elements that are ‘de se’ bound can interact with the concept generator variables posited by Percus and Sauerland to derive de re interpretations of embedded nominals. The proposed set-up has consequences for our understanding of puzzles raised by Heim and Sharvit concerning binding-theoretic effects with de re elements, and for the derivation of the obligatorily de se interpretation of controlled PRO.

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)

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.

This reissue of his collection of early essays, Logico-Linguistic Papers, is published with a brand new introduction by Professor Strawson but, apart from minor ...

Much recent work in philosophy of memory discusses the question whether episodic remembering is continuous with imagining. This paper contributes to the debate between continuists and discontinuists by considering a previously neglected source of evidence for continuism: the linguistic properties of overt memory and imagination reports (e.g. sentences of the form 'x remembers/imagines p'). I argue that the distribution and truth-conditional contribution of episodic uses of the English verb 'remember' is surprisingly similar to that of the verb 'imagine' – even (...) when compared to the distribution of other experiential attitude verbs like 'see', 'hallucinate', or 'dream'. This holds despite the presence of some remarkable truth-conditional differences between 'remember' and 'imagine'. I show how these differences can be explained by a continuist account of remembering on which remembering is past-directed, referential, and accurate experiential imagining. (shrink)

This thesis investigates the nature of the relation between mental representations in successful verbal communication, thought attribution, agreement, and disagreement — a relation which I call “samethinking”. The nature of samethinking raises several foundational questions about the nature of (non-natural) meaning, and the cognitive underpinnings of the emergence of culture. It bears on long-lasting puzzles in the philosophy of mind and language (such as Frege’s puzzle and Kripke’s puzzle about belief). Samethinking does not amount to sharing a reference (with “sharing" (...) I refer to two or more thinkers having something in common): it is more demanding. How can we explain and characterize this relation, more stringent than coreference, that is instantiated by a pair of thoughts when samethinking takes place? It is often assumed that this relation involves sharing a thought content more fine-grained than reference. In this thesis, I argue that the issue is more complex than what has been commonly assumed, and I suggest an alternative model in which sharing thought content is not necessary. (shrink)

Among philosophers, Fregeanism and sententialism are widely considered two of the leading theories of the semantics of attitude reports. Among linguists, these approaches have received little recent sustained discussion. This paper aims to bridge this divide. I present a new formal implementation of Fregeanism and sententialism, with the goal of showing that these theories can be developed in sufficient detail and concreteness to be serious competitors to the theories which are more popular among semanticists. I develop a modern treatment of (...) quantifying in for Fregeanism and sententialism, in the style of Heim and Kratzer, and then show how these theories can—somewhat surprisingly—account for “third readings” on the model of the “Standard Solution” from possible-worlds semantics. The resulting Fregean/sententialist proposal has a distinctive attraction: it treats data related to counterfactual attitudes —which have proven challenging to accommodate in the setting of possible worlds semantics—straightforwardly as third readings.

I observe that the “concept-generator” theory of Percus and Sauerland (2003), Anand (2006), and Charlow and Sharvit (2014) does not predict an intuitive true interpretation of the sentence “Plato did not believe that Hesperus was Phosphorus”. In response, I present a simple theory of attitude reports which employs a fine-grained semantics for names, according to which names which intuitively name the same thing may have distinct compositional semantic values. This simple theory solves the problem with the concept-generator theory, but, as (...) I go on to show, it has problems of its own. I present three examples which the concept-generator theory can accommodate, but the simple fine-grained theory cannot. These examples motivate the full theory of the paper, which combines the basic ideas behind the concept-generator theory with a fine-grained semantics for names. The examples themselves are of interest independently of my theory: two of them constrain the original concept-generator theory more tightly than previously discussed examples had. (shrink)

There are different ways in which imaginings can involve the first-person. I can imagine skiing down a mountain, looking down the slope, the wind whipping me in the face. I can also imagine myself skiing down a mountain from the outside, adopting the point of view of a spectator watching myself fly down the mountain. I can also imagine that I am someone else entirely, say Angela Merkel, skiing down a mountain. In this paper I develop and defend a new (...) account of the content of first-person imaginings. I first look at two existing accounts, one proposed by Francois Recanati (2007a, 2007b) and the other proposed by Dilip Ninan (2008), and I argue that they lack the resources to model the rich and distinct types of first-person imaginings that we can have. I then present and defend a new account that reconstrues the imagining from the inside vs. imagining from the outside distinction and can accommodate the various ways in which imaginings involve the first-person.

MILLIANISM and DESCRIPTIVISM are without question the two most prominent views with respect to the semantics of proper names. However, debates between MILLIANS and DESCRIPTIVISTS have tended to focus on a fairly narrow set of linguistic data and an equally narrow set of problems, mainly how to solve with Frege's puzzle and how to guarantee rigidity. In this article, the author focuses on a set of data that has been given less attention in these debates—namely, so-called predicative uses, bound uses, (...) and shifted uses of names. The author first shows that these data points seem to favor a DESCRIPTIVIST view over a MILLIAN view, but the author then introduces an alternative view of names that not only provides a simple and elegant way of dealing with the data, but also retains rigidity without becoming subject to the problems raised by Frege's puzzle. This is the view that names are variables, also called VARIABILISM. (shrink)

Hope is an attitude with a distinctive epistemological dimension: it is incompatible with knowledge. This chapter examines hope as it relates to knowledge but also to probability and inductive considerations. Such epistemic constraints can make hope either impossible, or, when hope remains possible, they affect how one’s epistemic situation can make hope rational rather than irrational. Such issues are especially relevant to when hopefulness may permissibly figure in practical deliberation over a course of action. So I consider cases of second-order (...) inductive reflection on when one should, or should not, be hopeful for an outcome with which one has a long record of experience: in other words, what is the epistemology behind when one should, if ever, stop hoping for outcomes which have failed one many times in the past?

ABSTRACT Quine insisted that the satisfaction of an open modalised formula by an object depends on how that object is described. Kripke's ‘objectual’ interpretation of quantified modal logic, whereby variables are rigid, is commonly thought to avoid these Quinean worries. Yet there remain residual Quinean worries for epistemic modality. Theorists have recently been toying with assignment-shifting treatments of epistemic contexts. On such views an epistemic operator ends up binding all the variables in its scope. One might worry that this yields (...) the undesirable result that any attempt to ‘quantify in’ to an epistemic environment is blocked. If quantifying into the relevant constructions is vacuous, then such views would seem hopelessly misguided and empirically inadequate. But a famous alternative to Kripke's semantics, namely Lewis' counterpart semantics, also faces this worry since it also treats the boxes and diamonds as assignment-shifting devices. As I'll demonstrate, the mere fact that a variable is bound is no obstacle to binding it. This provides a helpful lesson for those modelling de re epistemic contexts with assignment sensitivity, and perhaps leads the way toward the proper treatment of binding in both metaphysical and epistemic contexts: Kripke for metaphysical modality, Lewis for epistemic modality.

Dilip Ninan has raised a puzzle for centered world accounts of de re attitude reports extended to accommodate what he calls “counterfactual attitudes.” As a solution, Ninan introduces multiple centers to the standard centered world framework, resulting in a more robust semantics for de re attitude reports. However, while the so-called multi-centered world proposal solves Ninan’s counterfactual puzzle, this additional machinery is not without problems. In Section 1, I present the centered world account of attitude reports, followed by the extension (...) to counterfactual attitudes which Ninan targets with his puzzle. In Section 2, I pose the counterfactual puzzle and present Ninan’s multi-centered world solution, emphasizing similarities and differences between multi-centered and centered world accounts of attitude reports. In Section 3, I argue the counterfactual attitude wishing falls under the purview of the multi-centered proposal, but that the proposal generates false predictions for wish reports concerning unsatisfiable content. I canvass responses, ultimately concluding Ninan’s proposal requires substantial revisions. (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.

Kaplan (1989) famously claimed that monsters--operators that shift the context--do not exist in English and "could not be added to it". Several recent theorists have pointed out a range of data that seem to refute Kaplan's claim, but others (most explicitly Stalnaker 2014) have offered a principled argument that monsters are impossible. This paper interprets and resolves the dispute. Contra appearances, this is no dry, technical matter: it cuts to the heart of a deep disagreement about the fundamental structure of (...) a semantic theory. We argue that: (i) the interesting notion of a monster is not an operator that shifts some formal parameter, but rather an operator that shifts parameters that play a certain theoretical role; (ii) one cannot determine whether a given semantic theory allows monsters simply by looking at the formal semantics; (iii) theories which forbid shifting the formal "context" parameter are perfectly compatible with the existence of monsters (in the interesting sense). We explain and defend these claims by contrasting two kinds of semantic theory--Kaplan's (1989) and Lewis's (1980). (shrink)

I review Ninan’s Hundred Tickets case pertaining to quantification into epistemic modal contexts, and his counterpart theoretic way to address it (Ninan, Philos Rev, 2018). Ninan’s solution employs a ‘counterpart relation’ parameter intended to reflect how the domain of quantification is thought of in a context. This approach theoretically rules out the possibility of contexts where different ways of thinking about the domain can be deployed through different quantificational noun phrases. I bring out the case of the multiply de re (...) modal statement "Any ticket in photo #2 might be any ticket in photo #1" to challenge Ninan’s approach. I propose a different approach adapting a more complex ‘counterpart relation’ parameter due to Rabern (Inquiry, 2021). I attempt to flesh it out by relating it to a finer grained notion of epistemic possibility involving assignments to discourse referents. My approach can account for the aforementioned multiply de re statement, as well as address the Hundred Tickets case. (shrink)

The Centred View offers an account of the connection between imagination and possibility that combines the centred world framework with some allegedly appealing intuitions regarding our persistence over time. In particular, Dilip Ninan suggests that the Centred View has the theoretical advantage of respecting our intuitions about cases of personal identity in certain imaginative scenarios while also being compatible with physicalism. Unfortunately, the Centred View faces a series of serious objections and should ultimately be rejected.

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.

A counteridentical is a counterfactual with an identity statement in the antecedent. While counteridenticals generally seem non-trivial, most semantic theories for counterfactuals, when combined with the necessity of identity and distinctness, attribute vacuous truth conditions to such counterfactuals. In light of this, one could try to save the orthodox theories either by appealing to pragmatics or by denying that the antecedents of alleged counteridenticals really contain identity claims. Or one could reject the orthodox theory of counterfactuals in favor of a (...) hyperintensional semantics that accommodates non-trivial counterpossibles. In this paper, I argue that none of these approaches can account for all the peculiar features of counteridenticals. Instead, I propose a modified version of Lewis’s counterpart theory, which rejects the necessity of identity, and show that it can explain all the peculiar features of counteridenticals in a satisfactory way. I conclude by defending the plausibility of contingent identity from objections. (shrink)

This paper addresses a certain objection to the quantificational theory of definite descriptions. According to this objection, the quantificational account cannot provide correct interpretations of definite descriptions embedded in the non-doxastic attitude ascriptions and therefore ought to be rejected. In brief, the objection says that the quantificational theory is committed to the view that a sentence of the form “The F is G” is equivalent to the claim that there is a unique F and it is G, while the ascription (...) such as, e.g., “S wants the F to be G” is not equivalent to the statement that S wants there to be a F and for it to be G. I argue that this objection is invalid as it rests on a false assumption concerning the substitutivity of the relative clauses in the non-doxastic attitude ascriptions. (shrink)

In this paper, I raise a problem for standard precisifications of the Relational Analysis of attitude reports. The problem I raise involves counterfactual attitude verbs. such as ‘wish’. In short, the trouble is this: there are true attitude reports ‘ S wishes that P ’ but there is no suitable referent for the term ‘that P ’. The problematic reports illustrate that the content of a subject’s wish is intimately related to the content of their beliefs. I capture this fact (...) by moving to a framework in which ‘wish’ relates subjects to sets of pairs of worlds, or paired propositions, rather than—as is standardly assumed—sets of worlds. Although other types of counterfactual attitude reports, for example those involving ‘imagine’, may be similarly problematic, at this stage it is unclear whether they can be handled the same way.

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.

This chapter presents a new semantics for inductive empirical knowledge. The epistemic agent is represented concretely as a learner who processes new inputs through time and who forms new beliefs from those inputs by means of a concrete, computable learning program. The agent’s belief state is represented hyper-intensionally as a set of time-indexed sentences. Knowledge is interpreted as avoidance of error in the limit and as having converged to true belief from the present time onward. Familiar topics are re-examined within (...) the semantics, such as inductive skepticism, the logic of discovery, Duhem’s problem, the articulation of theories by auxiliary hypotheses, the role of serendipity in scientific knowledge, Fitch’s paradox, deductive closure of knowability, whether one can know inductively that one knows inductively, whether one can know inductively that one does not know inductively, and whether expert instruction can spread common inductive knowledge—as opposed to mere, true belief—through a community of gullible pupils.

A number of puzzles about propositional attitudes in semantics and philosophy revolve around apparent referential dependencies between different attitudes within a single agent’s mental state. In a series of papers, Hans Kamp offers a general framework for describing such interconnected attitude complexes, building on DRT and dynamic semantics. I demonstrate that Kamp’s proposal cannot deal with referential dependencies between semantically conflicting attitudes, such as those in Ninan’s puzzle about de re imagination. To solve the problem I propose to replace Kamp’s (...) treatment of attitudes as context change potentials with a two-dimensional analysis. (shrink)

Beliefs are commonly analyzed as binary relations between subjects and propositions. Perry and Lewis have shown that the standard account has difficulties in handling self-locating beliefs. Robert Stalnaker has recently put forward a version of the standard account that is supposed to overcome this problem. Stalnaker's motivation for defending the propositional account of belief is that it comes with a simple and powerful propositional model of communication. In this paper I argue that Stalnaker's proposal fails. The only way of upholding (...) the propositional account of belief is by abandoning the simple account of communication. (shrink)

Epistemic modal predicate logic raises conceptual problems not faced in the case of alethic modal predicate logic : Frege’s “Hesperus-Phosphorus” problem—how to make sense of ascribing to agents ignorance of necessarily true identity statements—and the related “Hintikka-Kripke” problem—how to set up a logical system combining epistemic and alethic modalities, as well as others problems, such as Quine’s “Double Vision” problem and problems of self-knowledge. In this paper, we lay out a philosophical approach to epistemic predicate logic, implemented formally in Melvin (...) Fitting’s First-Order Intensional Logic, that we argue solves these and other conceptual problems. Topics covered include: Quine on the “collapse” of modal distinctions; the rigidity of names; belief reports and unarticulated constituents; epistemic roles; counterfactual attitudes; representational vs. interpretational semantics; ignorance of co-reference vs. ignorance of identity; two-dimensional epistemic models; quantification into epistemic contexts; and an approach to multi-agent epistemic logic based on centered worlds and hybrid logic.

Subjective language has attracted substantial attention in the recent literature in formal semantics and philosophy of language Subjective meaning: alternatives to relativism, De Gruyter, Berlin, pp 1–19, 2016; Lasersohn in Subjectivity and perspective in truth-theoretic semantics, Oxford University Press, Oxford, 2017; Vardomskaya in Sources of subjectivity, Ph.D. thesis, University of Chicago, IL, 2018; Zakkou in Faultless disagreement: a defense of contextualism in the realm of personal taste, Vittorio Klostermann, Frankfurt a. M., 2019b). Most current theories argue that Subjective Predicates, which (...) express matters of opinion, semantically differ from ordinary predicates, which express matters of fact. We will call this view “SP exceptionalism”. This paper addresses SP exceptionalism by scrutinizing the behavior of SPs in attitude reports, which, as we will argue, significantly constrains the space of analytical options and rules out some of the existing theories. As first noticed by Stephenson :487–525, 2007a; Towards a theory of subjective meaning, Ph.D. thesis, Massachusetts Institute of Technology, Cambridge, MA, 2007b), the most prominent reading of embedded SPs is one where they talk about the attitude holder’s subjective judgment. As is remarked sometimes :327–352, 2009; Pearson in J Semant 30:103–154, 2013a), this reading is not the only one: embedded SPs may also talk about someone else’s, non-local, judgment. We concentrate specifically on such cases and show that non-local judgment is possible if and only if SPs are used within a DP that is outside main predicate position and that entire DP is read de re. We demonstrate that the behavior of SPs in attitude reports does not differ from that of ordinary predicates: it follows from general constraints on intersective modification and intensional quantification Ways of scope taking, Springer, Dordrecht, pp 183–215, 1997; Musan in On the temporal interpretation of noun phrases, Garland, New York, 1997; Percus in Nat Lang Semant 8:173–229, 2000; Keshet in Good intensions: paving two roads to a theory of the de re/de dicto distinction, Ph.D. thesis, Massachusetts Institute of Technology, Cambridge, MA, 2008). We argue that this unexceptional behavior of SPs in fact has unexpected consequences for SP exceptionalism. Precisely because SPs have been argued to be semantically different from ordinary predicates, not all theories correctly predict these less-studied data: some overgenerate :691–706, 2007; Sæbø 2009) and some undergenerate Proceedings of Sinn und Bedeutung, vol 11, pp 433–447, 2007; Pearson 2013a). Out of the currently available theories, only relativist accounts :643–686, 2005; MacFarlane 2014; Bylinina in J Semant 34, 291–331, 2017; Coppock in Linguist Philos 41:125–164, 2018) predict the right interpretation, and only that interpretation. We thus present a novel empirical argument for relativism, and, more generally, formulate a constraint that has to be taken into consideration by any view that advocates SP exceptionalism. (shrink)

This book combines insights from philosophy and linguistics to develop a novel framework for theorizing about linguistic meaning and the role of context in interpretation. A key innovation is to introduce explicit representations of context — assignment variables — in the syntax and semantics of natural language. The proposed theory systematizes a spectrum of “shifting” phenomena in which the context relevant for interpreting certain expressions depends on features of the linguistic environment. Central applications include local and nonlocal contextual dependencies with (...) quantifiers, attitude ascriptions, conditionals, questions, and relativization. The result is an innovative, philosophically informed compositional semantics compatible with the truth-conditional paradigm. (shrink)

In two‐dimensional semantics in the tradition of Davies and Humberstone, whether a singular term receives an epistemically shifted reading in the scope of a modal operator depends on whether the world considered as actual is shifted. This means that epistemically shifted readings should be available only in environments where an explicit contrast between the actual world and some counterfactual worlds cannot be made. In this paper, I argue that this is incorrect. Whether a singular term receives an epistemically shifted reading (...) is independent of whether the world treated as actual is shifted. This, I argue, undermines the two‐dimensionalist account of epistemic shift. I then turn to the question how a positive view should handle these two phenomena separately. I argue for treating singular terms with a version of counterpart theory in which the difference between epistemically shifted and other readings is determined in the context of utterance. (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)

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.

As Quine observed, the following sentence has a reading which, if true, would be of special interest to the authorities: Ralph believes that someone is a spy. This is the reading where the quantifier is naturally understood as taking wide scope relative to the attitude verb and as binding a variable within the scope of the attitude verb. This essay is interested in addressing the question what the semantic analysis of this kind of reading should look like from a Fregean (...) perspective—a perspective according to which attitude states are generally relations to structured Fregean thoughts composed of senses. The Fregean view faces a challenge of compositionality here. This essay describes the challenge and offers a response on the Fregean's behalf. (shrink)

On a popular view dating back to Russell, descriptions, both definite and indefinite alike, work syntactically and semantically like quantifiers. I have an argument against Russell's view. The argument supports a different picture: descriptions can behave syntactically and semantically like variables. This basic idea can be implemented in very different systematic analyses, but, whichever way one goes, there will be a significant departure from Russell. The claim that descriptions are variables is not new: what I offer is a new way (...) of defending it. The argument centers on attitude reports. I argue that we should recognize a new reading of descriptions under attitude reports, which I call ‘singular opaque’. The existence of this reading cannot be explained on the traditional Russellian view, and demands a switch to the variable view. Along the way, some interesting new facts about attitude reports come to light. (shrink)

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)
