Mental files, in Recanati's framework, function as 'singular terms in the language of thought' ; they serve to think about objects in the world (and to store information about them). But they have a derived, metarepresentational function : they serve to represent how other subjects think about objects in the world. To account for the metarepresentational use of files, Recanati introduces the notion of an 'indexed file', i.e. a vicarious file that stands, in the subject's mind, for another subject's file (...) about an object. Using that notion, he argues, one can provide an analysis of attitude ascriptions and the conniving use of empty singular terms. (shrink)

A new puzzle about material constitution is presented and its implications are discussed. The moral of the story is that familiar intuitions supporting a neo-Aristotelian view of the material world are contradictory. To accommodate these intuitions is to embrace inconsistency. Therefore, neo-Aristotelianism is worse off for its intuitive appeal. Furthermore, the puzzle is used to argue for an account of ordinary modal thought and language that’s reconstructive, or ameliorative.

Frege's Puzzle is a founding problem in analytic philosophy. It lies at the intersection of central topics in the philosophy of language and mind: the theory of reference, the nature of propositional attitudes, the nature of semantic theorizing, the relation between semantics and pragmatics, etc. This chapter is an overview of the puzzle and of the space of contemporary approaches to it.

This dissertation looks at a set of interconnected questions concerning the foundations of probability, and gives a series of interconnected answers. At its core is a piece of old-fashioned philosophical analysis, working out what probability is. Or equivalently, investigating the semantic question of what is the meaning of ‘probability’? Like Keynes and Carnap, I say that probability is degree of reasonable belief. This immediately raises an epistemological question, which degrees count as reasonable? To solve that in its full generality would (...) mean the end of human inquiry, so that won’t be attempted here. Rather I will follow tradition and merely investigate which sets of partial beliefs are coherent. -/- The standard answer to this question, what is commonly called the Bayesian answer, says that degrees of belief are coherent iff they form a probability function. I disagree with the way this is usually justified, but subject to an important qualification I accept the answer. The important qualification is that degrees of belief may be imprecise, or vague. Part one of the dissertation, chapters 1 to 6, looks largely at the consequences of this qualification for the semantic and epistemological questions already mentioned. It turns out that when we allow degrees of belief to be imprecise, we can discharge potentially fatal objections to some philosophically attractive theses. Two of these, that probability is degree of reasonable belief and that the probability calculus provides coherence constraints on partial beliefs, have been mentioned. Others include the claim, defended in chapter 4, that chance is probability given total history. -/- As well as these semantic and epistemological questions, studies of the foundations of probability usually include a detailed discussion of decision theory. For reasons set out in chapter 2, I deny we can gain epistemological insights from decision theory. Nevertheless, it is an interesting field to study on its own, and it might be expected that there would be decision theoretic consequences of allowing imprecise degrees of belief. As I show in part two, this expectation seems to be mistaken. Chapter 9 shows that there aren’t interesting consequences of this theory for decision theory proper, and chapters 10 and 11 show that Keynes’s attempt to use imprecision in degrees of belief to derive a distinctive theory of interest rates is unsound. -/- Chapters 7 and 8 provide a link between these two parts. In chapter 7 I look at some previous philosophical investigations into the effects of imprecision. In chapter 8 I develop what I take to be the best competitor to the theory defended here – a constructivist theory of probability. On this view degrees of belief are precise, but the relevant coherence constraint is a constructivist probability calculus. This view is, I think, mistaken, but the calculus has some intrinsic interest, and there are at least enough arguments for it to warrant a chapter-length examination. (shrink)

The book is about logical analysis of natural language. Since we humans communicate by means of natural language, we need a tool that helps us to understand in a precise manner how the logical and formal mechanisms of natural language work. Moreover, in the age of computers, we need to communicate both with and through computers as well. Transparent Intensional Logic is a tool that is helpful in making our communication and reasoning smooth and precise. It deals with all kinds (...) of linguistic context in a fully compositional and anti-contextual way. (shrink)

De jure coreference in a discourse is typically understood as explicit coreference that speakers are required to recognize in order to count as having correctly understood the discourse. For example, in an utterance of the sentence ‘Tom went to the market because he needed soy milk’, the two underlined terms are typically coreferential in a way that appreciating their coreference is required to fully understand the utterance. Often, de jure coreference is understood as an equivalence relation, so in particular it (...) is thought of as a transitive relation. However, Pinillos (Philos Stud 154(2):301–324, 2011) provides examples that apparently challenge the transitivity of de jure coreference. In this paper, I argue for two claims. First, while it is inconclusive whether the relevant terms in Pinillos’s examples satisfy his third condition, it is much clearer that they fail to satisfy his first two conditions. Given that Pinillos’s conditions capture important characteristics of de jure coreference, his examples do not successfully show the non-transitivity of de jure coreference. Second, I present an alternative account of his examples, one that shows which representation the anaphoric pronoun in an example of the sort that he presents is de jure coreferential with. (shrink)

Many philosophers have argued or taken for granted that Frege's puzzle has little or nothing to do with identity statements. I show that this is wrong, arguing that the puzzle can only be motivated relative to a thinker's beliefs about the identity or distinctness of the relevant object. The result is important, as it suggests that the puzzle can be solved, not by a semantic theory of names or referring expressions as such, but simply by a theory of identity statements. (...) To show this, I sketch a framework for developing solutions of this sort. I also consider how this result could be implemented by two influential solutions to Frege's puzzle, Perry's referential-reflexivism and Fine's semantic relationism. (shrink)

This essay examines the syntax of names. It argues that names are a syntactically and not just semantically distinctive class of expressions. Its central claim is that names are a distinguished type of anaphoric device—devices of explicit co-reference. Finally it argues that appreciating the true syntactic distinctiveness of names is the key to resolving certain long-standing philosophical puzzles that have long been thought to be of a semantic nature.

Philosophers of language have long recognized that in opaque contexts, such as those involving propositional attitude reports, substitution of co-referring names may not preserve truth value. For example, the name ‘Clark Kent’ cannot be substituted for ‘Superman’ in a context like:1. Lois believes that Superman can flywithout a change in truth value. In an earlier paper, Jennifer Saul demonstrated that substitution failure could also occur in ‘simple sentences’ where none of the ordinary opacity-producing conditions existed, such as:2. Superman leaps more (...) tall buildings than Clark Kent does.Accounts focusing on opacity were unable to explain our ‘anti-substitution intuitions’ in such cases.In Simple Sentences, Substitution, and Intuitions, Saul extends her earlier work. She provides a comprehensive presentation and criticism of recent accounts of simple sentence substitution failure, and proposes a new approach drawing on psychological evidence about cognitive processing. Saul's purpose is not merely to solve the substitution puzzle cases, but to make …. (shrink)

Section 1 discerns ambiguity in the word “truth”, observing that the term is used most naturally in reference to truth-bearers rather than truth-makers. Focusing on truths-as-truth-bearers, then, it would appear that alethic realism conflicts with metaphysical realism as naturalistically construed. Section 2 discerns ambiguity in the purporting of truth (as in assertion), conjecturing that all expressions, not just those found in traditionally recognized opaque contexts, can be read intensionally (as well, perhaps, as extensionally). For instance, we would not generally want (...) to say that “The Matterhorn is 4,500 m high” expresses the same truth as “The Matterhorn is 14763.7795276 feet high” (or that it is true in the same range of utterance contexts), even though the two are extensionally equivalent. The reason is that they express different intensions. (shrink)

In this essay I will defend a novel version of the indexical view on proper names. According to this version, proper names have a relatively sparse truth-conditional meaning that is represented by their rigid content and indexical character, but a relatively rich use-conditional meaning, which I call the (contextual) constraint of a proper name. Firstly, I will provide a brief outline of my favoured indexical view on names in contrast to other indexical views proposed in the relevant literature. Secondly, two (...) general motivations for an indexical view on names will be introduced and defended. Thirdly, I will criticize the two most popular versions of the indexical view on names: formal variable accounts and salience-based formal constant accounts. In the fourth and final section, I will develop my own use-conditional indexical view on names in three different steps by confronting an initial version of this view with three different challenges.

In this paper I argue that descriptive content associated with a proper name can serve as a truth-conditionally relevant adjunct and be an additional contribution of the name to the truth-conditions. Definite descriptions the so-and-so associated by speakers with a proper name can be used as qualifying prepositional phrases as so-and-so, so sentences containing a proper name NN is doing something could be understood as NN is doing something as NN (which means as so-and-so). Used as an adjunct, the descriptive (...) content of a proper name expresses the additional circumstances of an action (a manner, reason, goal, time or purpose) and constitute a part of a predicate. I argue that qualifying prepositional phrases should be analyzed as predicate modifiers and propose a formal representation of modified predicates. The additional truth-conditional relevance of the descriptive content of a proper name helps to explain the phenomenon of the substitution failure of coreferential names in simple sentences.

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)

For various reasons several authors have enriched classical first order syntax by adding a predicate abstraction operator. “Conservatives” have done so without disturbing the syntax of the formal quantifiers but “revisionists” have argued that predicate abstraction motivates the universal quantifier’s re-classification from an expression that combines with a variable to yield a sentence from a sentence, to an expression that combines with a one-place predicate to yield a sentence. My main aim is to advance the cause of predicate abstraction while (...) cautioning against revisionism. In so doing, however, I shall pursue a secondary aim by conveying mixed blessings to those who hold the view that in the logical sense of “existence” some existing object is such as to exist contingently. Advocates of this view must concede Williamson’s recent contention that the domain of unrestricted objectual quantification could not have been narrower than it is actually, but predicate abstraction affords them some hope of accommodating this concession.

Russellianism is characterized as the view that ‘that’-clauses refer to Russellian propositions, familiar set-theoretic pairings of objects and properties. Two belief-reporting sentences, S and S*, possessing the same Russellian content, but differing in their intuitive truthvalue, are provided. It is argued that no Russellian explanation of the difference in apparent truthvalue is available, with the upshot that the Russellian fails to explain how a speaker who asserts S but rejects S* can be innocent of inconsistency, either in what she says (...) or, at least, in what she implicates. Yet, while there is no semantic or pragmatic explanation of the substitution failure consistent with Russellianism, there remains the possibility of a purely psychological explanation that is, nonetheless, Russellian. This is an attractive option. It comes at a cost, however, since, in abandoning the project of providing a semantic or pragmatic explanation of anti-substitutivity intuitions, the Russellian is no longer in the business of explaining how a rational, well-informed speaker, with no incentive to mislead, can avoid inconsistency in reporting the facts as they appear.

ABSTRACT Recently, in a series of papers, Joshua Spencer has introduced, defended, and developed a modified version of Neo-Russellianism, namely Plenitudinous Russellianism, according to which there are structurally identical but numerically distinct singular Russellian propositions. PR claims to provide novel semantic solutions to all the major problems that NR faces with no radical revision in NR. In this paper, I introduce a semantic puzzle for PR: the view leads to the violation of the principle of substitutivity of co-referential proper names (...) within simple ‘that’-clauses. I consider different responses to my argument, and show that none of them is fully satisfactory for the Russellian. I conclude that PR needs to depart from NR more radically. RÉSUMÉ Récemment, Joshua Spencer a publié une série d'articles où il expose, défend et développe une version modifiée du Néo-Russellianisme, appelée Russellianisme de plénitude, selon laquelle il y a des propositions Russelliennes singulières structurellement identiques mais numériquement distinctes. Ce Russellianisme de plénitude prétend apporter de nouvelles solutions sémantiques à tous les problèmes majeurs auxquels le NR se confronte, sans pour autant procéder à une révision radicale du NR. Dans cet article, je mettrai le PR face à un casse-tête : cette vision mène à la violation du principe de substitution des noms propres co-référentiels au sein des subordonnées complétives simples. Je tâcherai de considérer différentes réponses à mon argument et de montrer qu'aucune d'entre elles n'est pleinement satisfaisante pour un Russellien. Je vais conclure que le PR devrait s’écarter plus radicalement du NR. (shrink)

According to what I call theidentity view, omissions are actual events. For example, the nominal ‘Ali's non-jogging’ denotes whatever Ali is doing at the time she is said not to be jogging. Some have objected that omissions (and more generally absences) cannot be events, since the two do not have the same causal relations. I show how advocates of the identity view can offer a pragmatic account of the data the objection relies on.

The generic pronoun 'one' (or its empty counterpart, arbitrary PRO) exhibits a range of properties that show a special connection to the first person, or rather the relevant intentional agent (speaker, addressee, or described agent). The paper argues that generic 'one' involves generic quantification in which the predicate is applied to a given entity ‘as if’ to the relevant agent himself. This is best understood in terms of simulation, a central notion in some recent developments in the philosophy of mind (...) and cognitive science (Simulation Theory). (shrink)

Richard Heck, Jr has recently argued against Russellianism about proper names not in the usual way—by appeal to “intuitions” about the truth conditions of “that”-clause belief ascriptions—but by appeal to our need to specify beliefs in a way that reflects their individuation. Since beliefs are individuated by their psychological roles and not their Russellian contents, he argues, Russellianism is precluded in principle from accounting for our ability to specify beliefs in ordinary language. I argue that Heck thus makes things easier (...) for the Russellian. For by framing the issue as one concerning the specificatory powers of ordinary language in general, rather than just of “that”-clause ascriptions, Heck weakens the implications of any claim about the semantics of that one type of belief-specifying locution. I augment this diagnosis with a positive account of the specificatory usefulness, and attested commonness, of (partly or wholly) quotational belief ascriptions, e.g. “Lois believes that ‘Superman’ is at the meeting.” This proposal is not of the usual sort concerning such locutions since it does not involve the (dubious) claim that they are in some way equivalent to “that”-clause ascriptions. (shrink)

While proper names in argument positions have received a lot of attention, this cannot be said about proper names in the naming construction, as in “Call me Al”. I argue that in a number of more or less familiar languages the syntax of naming constructions is such that proper names there have to be analyzed as predicates, whose content mentions the name itself (cf. “quotation theories”). If proper names can enter syntax as predicates, then in argument positions they should have (...) a complex structure, consisting of a determiner and its restriction, like common nouns (cf. “definite description theories of proper names”). Further consideration of the compositional semantics of proper names in the naming construction also shows that they have another argument slot, that of the naming convention. As a result, we will be able to account for the indexicality of proper names in argument positions and provide compositional semantics of complex and modified proper names (e.g., the famous detective Sherlock Holmes ).

Anti‐substitution intuitions play a central role in discussion of the semantics of propositional attitude ascriptions, and all theorists seem to agree that these intuitions should be explained by either semantic or pragmatic means. Jennifer Saul (2007) has recently argued that it is impossible to explain all our anti‐substitution intuitions thus. In particular, she argues that any account of the semantics of propositional attitude ascriptions faces the ‘Enlightenment Problem’ – i.e. no such account can explain the fact that we have anti‐substitution (...) intuitions about utterances of speakers who are ‘unenlightened’ as to the fact that certain names are co‐referential. In this paper, I suggest an alternative explanation of our intuitions about unenlightened utterances, and in doing so offer an original strategy for explaining truth‐conditional intuitions by either semantic or pragmatic means. (shrink)

Philosophers of language traditionally take it that anti-substitution intuitions teach us about the content of belief reports. Jennifer Saul [1997, 2002 (with David Braun), 2007] challenges this lesson. Here I offer a response to Saul’s challenge. In the first two sections of the article, I present a common sense justification for drawing conclusions about content from anti-substitution intuitions. Then, in Sect. 3, I outline Saul’s challenge—what she calls ‘the Enlightenment Problem’. Finally, in Sect. 4, I argue that Saul’s challenge does (...) not undermine the common sense justification presented in Sects. 1 and 2. I avoid the challenge by arguing that anti-substitution intuitions are not directly sensitive to the content of the sentences that produce them, but rather to the possibility that one could have distinct ways of thinking about an object.

The 'substitution argument' purports to demonstrate the falsity of Russellian accounts of belief-ascription by observing that, e.g., these two sentences: (LC) Lois believes that Clark can fly. (LS) Lois believes that Superman can fly. could have different truth-values. But what is the basis for that claim? It seems widely to be supposed, especially by Russellians, that it is simply an 'intuition', one that could then be 'explained away'. And this supposition plays an especially important role in Jennifer Saul's defense of (...) Russellianism, based upon the existence of an allegedly similar contrast between these two sentences: (PC) Superman is more popular than Clark. (PS) Superman is more popular than Superman. The latter contrast looks pragmatic. But then, Saul asks, why shouldn't we then say the same about the former? The answer to this question is that the two cases simply are not similar. In the case of (PC) and (PS), we have only the facts that these strike us differently, and that people will sometimes say things like (PC), whereas they will never say things like (PS). By contrast, there is an argument to be given that (LS) can be true even if (LC) is false, and this argument does not appeal to anyone's 'intuitions'. The main goal of the paper is to present such a version of the substitution argument, building upon the treatment of the Fregan argument against Russellian accounts of belief itself in "Solving Frege's Puzzle". A subsidiary goal is to contribute to the growing literature arguing that 'intuitions' simply do not play the sort of role in philosophical inquiry that so-called 'experimental philosophers' have supposed they do.

Consider the sentence “Lois knows that Superman flies, but she doesn’t know that Clark flies”. In this paper we defend a Millian contextualist semantics for propositional attitude ascriptions, according to which ordinary uses of this sentence are true but involve a mid-sentence shift in context. Absent any constraints on the relevant parameters of context sensitivity, such a semantics would be untenable: it would undermine the good standing of systematic theorizing about the propositional attitudes, trivializing many of the central questions of (...) epistemology, the philosophy of mind, and the philosophy of action. In response to this problem, we prove a series of tenability results. We show that, given certain constraints on the parameters of context sensitivity, there is a broad class of principles of propositional attitude psychology whose good standing follows from corresponding claims about people’s mental representations. But these constraints also have some surprising consequences: they are jointly incompatible with coarse-grained theories of propositions, and they are in tension with a natural picture of how speakers and hearers coordinate on the interpretation of attitude ascriptions. In light of these consequences we explore different ways in which the contextualist picture might be developed, and argue that our preferred way compares favorably with Fregeanism and neo-Russellianism.

Wittgenstein discusses speakers exploiting context to inject meaning into the sentences that they use. One facet of situation comedy is context-injected ambiguity, where scriptwriters artfully construct situations such that, because of conflicting contextual clues, a character, though uttering a sentence that contains neither ambiguous words nor amphibolous contruction may plausibly be interpreted in at least two distinct ways. This highlights an important distinction between the (concise) sentence that a speaker uses and what the speaker means, the disclosure of which may (...) require considerable spelling out. Understanding this phenomenon of nonindexical contextualism is the key to solving, inter alia , problems where, puzzlingly, exchanging a singular term in a statement with a co-referential one fails to preserve truth-value. This is a rare case where there is a huge debate in the recent literature that is decisively settled by Wittgenstein’s approach. (shrink)

This article explores the ethics of pseudonymous publication of nonfiction by examining what and why an author might hide behind the veil of pseudonymity, when this is and is not appropriate, and when it is deemed appropriate what measures should be taken to ensure accountability despite the veil. The argument begins by assuming that the sole duty an author has qua author is to his audience and centers on issues in both ethics and philosophy of language.

In Attitude Problems, I gave an account of opacity in the complement of intensional transitive verbs that combined neo-Davidsonian event-semantics with a hidden-indexical account of substitution failure. In this paper, I extend the account to clausal verbs.

There is a well-known argument from Leibniz's Law for the view that coincident material things may be distinct. For given that they differ in their properties, then how can they be the same? However, many philosophers have suggested that this apparent difference in properties is the product of a linguistic illusion; there is just one thing out there, but different sorts or guises under which it may be described. I attempt to show that this ‘opacity’ defence has intolerable consequences for (...) the functioning of our language and that the original argument should therefore be allowed to stand. (shrink)

Many competent speakers initially judge that (i) is true and (ii) isfalse, though they know that (iii) is true. (i) Superman leaps more tallbuildings than Clark Kent.

This is a collection of Paul Churchland's recent essays which have in common an overarching research programme aimed at identifying the scope and the importance of the contributions that neuroscience has made and will make to philosophy of mind, moral philosophy, epistemology and metaphysics. The general structure of many of the essays included in the collection is as follows: there is a long-standing problem in the philosophical literature which has escaped not only a convincing solution but also a straightforward analysis (...) of what the solution should look like, and how it could be achieved. Then the neurosciences start addressing a relevantly connected problem, or progress in such a way as to make a difference to our understanding of the original problem, and now a solution is in sight or, at least, we know roughly what the solution should look like.The way in which Churchland presents and defends his research programme in the essays included in the collection is praiseworthy for at least two reasons. First, Churchland's attempt to argue for the relevance of cognitive neurobiology for long-standing philosophical problems is seemingly effortless, which is a very rare …. (shrink)

Ever since Kripke’s influential arguments against descriptivism philosophers have attempted to provide solutions to Frege’s puzzle of substitution failure that adhere to Naïve Semantics—the view that names contribute their referents and referents alone to propositions expressed by sentences containing them. Recently, philosophers have also appealed to psychological objects called mental files, which are used to represent and store information on individuals, in solving the puzzle. Combining the two promises to revive a simple commonsensical theory while, at least prima facie, doing (...) away with the need to rely on Fregean senses. Though I welcome the combined approach, I argue that the only plausible version of it is a pretense-based one. (shrink)

This manuscript focuses on a problem for Millian Russellianism raised by Fine : “[Assuming] that we are in possession of the information that a Fs and the information that a Gs, it appears that we are sometimes justified in putting this information ‘together’ and inferring that a both Fs and Gs. But how?” It will be my goal to determine a Millian-Russellian solution to this problem. I will first examine Nathan Salmon’s Millian-Russellian solution, which appeals to a non-semantic and subjective (...) notion of coordination defined in terms of guises. I will object that in order to convincingly solve a specific version of Fine’s problem, identity conditions for guises must be provided. On the other hand, the most plausible way to individuate guises is by means of the equivalence classes of coordination itself. But, if so, the guise-based strategy to solve Fine’s problem risks being circular; in addition, there are serious doubts that coordination is transitive. An alternative Millian-Russellian solution to Fine’s problem will then be explored, which gives up guises and employs, instead, a non-semantic and subjective relation of coordination not defined in terms of guises, along with occurrences of Russellian propositions of a special sort, for which identity conditions will be provided and via which token attitude states intuitively more fine-grained than guises will be individuated.

I argue that an individual has aspects numerically identical with it and each other that nonetheless qualitatively differ from it and each other. This discernibility of identicals does not violate Leibniz's Law, however, which concerns only individuals and is silent about their aspects. They are not in its domain of quantification. To argue that there are aspects I will appeal to the internal conflicts of conscious beings. I do not mean to imply that aspects are confined to such cases, but (...) the best way to start is to recognize them experientially. We can feel the conflicts within ourselves. In doing so we can feel some of our aspects. I will try to enhance our understanding of the concept of aspect by listing and formalizing some principles for its use. After that I will argue that all sorts of individual things have aspects, not just people who are conflicted. (shrink)

Semanticists face substitution challenges even outside of contexts commonly recognized as opaque. Jennifer M. Saul has drawn attention to pairs of simple sentences - her term for sentences lacking a that-clause operator - of which the following are typical: -/- (1) Clark Kent went into the phone booth, and Superman came out. (1*) Clark Kent went into the phone booth, and Clark Kent came out. -/- (2) Superman is more successful with women than Clark Kent. (2*) Superman is more successful (...) with women than Superman. -/- She challenges us to explain why the upper and lower sentences in each pair differ, or at least appear to differ, in their truth-values and hence truth-conditions. This appearance of substitution failure is inherently puzzling. Moreover, it is taken by Saul to generate a dilemma for anyone hostile to direct reference accounts of that-clause constructions. Direct reference theorists regard the appearance of substitution failure in that-clause contexts as mere appearance, to be dealt with pragmatically rather than semantically. -/- Critics of such accounts need to say something about simple-sentence cases. If they choose to allow that intuitions of substitution failure can be over-ridden and explained away pragmatically in simple-sentence cases but not in that-clause cases, they lay themselves open to the charge of operating a double standard. But if they do not choose this option, they must offer a semantic explanation of apparent substitution failure in simple-sentence cases - no easy task, it turns out. Other respondents to Saul's challenge have sought to provide elaborate semantic treatments. In contrast, this paper proposes a far simpler pragmatic explanation of intuitions of substitution failure in simple sentences, an explanation that deploys no more resources than are to be found in Grice's 'Logic and Conversation'. Ironically, this proposal turns out to be incompatible with a direct reference perspective. So if it is, as I maintain, the most plausible treatment of simple-sentence cases available, Saul's initial thought gets turned around 180 degrees: the phenomenon she has drawn attention to ends up representing a challenge to supporters of direct reference theories.

We explore the view that Frege's puzzle is a source of straightforward counterexamples to Leibniz's law. Taking this seriously requires us to revise the classical logic of quantifiers and identity; we work out the options, in the context of higher-order logic. The logics we arrive at provide the resources for a straightforward semantics of attitude reports that is consistent with the Millian thesis that the meaning of a name is just the thing it stands for. We provide models to show (...) that some of these logics are non-degenerate. (shrink)

The paper is an addition to the intensionalist approach to decision theory, with emphasis on game theoretic modelling. Extensionality in games is an a priori requirement that players exhibit the same behavior in all algebraically equivalent games on pain of irrationality. Intensionalism denies that it is always irrational to play differently in differently represented but algebraically equivalent versions of a game. I offer a framework to integrate game non-extensionality with the more familiar idea of linguistic non-extensionality from philosophy of language, (...) followed by applications of it based on toy examples of well-known game models. I argue that the notion of what I call “Intensional Nash Equilibrium” is, in effect, very useful in understanding human decision-making. (shrink)

I develop and argue for a novel theory of the mental state of identity confusion. I also argue that this mental state can corrupt the proper function of singular terms in linguistic communication. Finally, I propose a theory according to which identity confusion should be treated as a the source of a new sort of linguistic performance error, similar to malapropism, slips of the tongue, and so-called intentional obfuscation (inducing false belief by manipulating language in specific ways). -/- Going into (...) a bit more detail, I start by arguing that contemporary analytic philosophy, and philosophy of language in particular, has been dominated by a ‘puzzle-driven’ methodology. This tradition, I claim, seeks to provide a coherent system for describing semantic features of all conceivable cases where a speaker is confused about the identity or distinctness of an object. On my view, identity confusion is a mental state of an agent who either believes falsely that a is identical to b or believes falsely that a is not identical to b. I show how many influential arguments in philosophy – e.g., Kripke on semantic reference and speaker’s reference – are invalidated because of false assumptions about the state of identity confusion. -/- More positively, I assume an ‘explanation-driven’ approach, combining strands in Gricean intentionalism and Ruth Millikan’s teleosemantics. On this view, confused speakers are ‘sub-optimal’: their mental state disrupts the proper function of the relevant singular terms in their idiolects. Furthermore, I flesh out a theoretically fruitful notion of ‘edenic reference,’ which idealizes away from confusion in defining the optimal or stabilizing function of singular terms. I argue that speakers must satisfy certain broadly cognitive constraints if their utterances are to play a role in explaining the maintenance of a practice of using a singular term in a linguistic community.
