There is a long-standing disagreement among Branching-Time theorists. Even though they all believe that the branching representation accurately grasps the idea that the future, contrary to the past, is open, they argue whether this representation is compatible with the claim that one among many possible futures is distinguished—the single future that will come to be. This disagreement is paralleled in an argument about the bivalence of future contingents. The single, privileged future is often called the Thin Red Line. I reconstruct (...) the history of the arguments for and against this idea. Then, I propose my own version of the Thin Red Line theory which is immune to the major objections found in the literature. I argue that the semantic disagreement is grounded in distinct metaphysical presuppositions. My solution is expressed in a conceptual framework proposed by John MacFarlane, who distinguishes semantics from postsemantics. I extend his distinction and introduce a new notion of presemantics to elucidate my idea. (shrink)

Recent criticisms of non-reductive accounts of color assume that the only arguments for such accounts are a priori arguments. I put forward a posteriori arguments for a non-reductive account of colors which avoids those criticisms.

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical indefeasibility is essential to the primary notion of the a priori ; however, the indefeasibility requirement should be interpreted in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with the (...) naturalist’s commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish empiricism, so fallibilist apriorism represents a distinct position. (shrink)

It is argued that philosophers who adopt the perdurance theory of persistence and who subscribe to the principle of Unrestricted Mereological Composition (UMC) are in a position to regard “Phosphorus is Hesperus” as false.

Kadri Vihvelin, in "What time travelers cannot do" (Philos Stud 81: 315-330, 1996), argued that "no time traveler can kill the baby who in fact is her younger self, because (V1) "if someone would fail to do something, no matter how hard or how many times she tried, then she cannot do it", and (V2) if a time traveler tried to kill her baby self, she would always fail. Theodore Sider (Philos Stud 110: 115-138, 2002) criticized Vihvelin's argument, and Ira (...) Kiourti (Philos Stud 139: 343-352, 2008) criticized both Vihvelin's argument and Sider's critique. I present a critique of Vihvelin's argument different from both Sider's and Kiourti's critiques: I argue in a novel way that both V1 and V2 are false. Since Vihvelin's argument might be understood as providing a challenge to the possibility of time travel, if my critique succeeds then time travel survives such a challenge unscathed. (shrink)

David Lewis (1980) proposed the Principal Principle (PP) and a “reformulation” which later on he called ‘OP’ (Old Principle). Reacting to his belief that these principles run into trouble, Lewis (1994) concluded that they should be replaced with the New Principle (NP). This conclusion left Lewis uneasy, because he thought that an inverse form of NP is “quite messy”, whereas an inverse form of OP, namely the simple and intuitive PP, is “the key to our concept of chance”. I argue (...) that, even if OP should be discarded, PP need not be. Moreover, far from being messy, an inverse form of NP is a simple and intuitive Conditional Principle (CP). Finally, both PP and CP are special cases of a General Principle (GP); it follows that so are PP and NP, which are thus compatible rather than competing. (shrink)

My main aim in this paper is to clarify the concepts of referential success and of referential continuity that are so crucial to the scientific realism debate. I start by considering the three dominant theories of reference and the intuitions that motivate each of them. Since several intuitions cited in support of one theory conflict with intuitions cited in support of another something has to give way. The traditional policy has been to reject all intuitions that clash with a chosen (...) theory. A more radical policy, tied to some experimental philosophers, has called for the rejection of any evidential role for intuitions. I explore a largely ignored third alternative, i.e. saving intuitions (and their evidential role) even when they are at odds. To accommodate conflicting intuitions different sets of internally consistent (yet externally inconsistent) intuitions are taken to lend credence to different concepts of reference. In the current context, this means that the concepts of referential success and referential continuity are not monolithic. They are what I call 'polylithic'. This paper is as much about meta-philosophical concerns with the role of intuitions as it is about reference and the scientific realism debate. Regarding the former I hope that a blueprint will emerge for similar projects in other philosophical domains. Regarding the latter, I hope that polylithicity helps disentangle claims about referential success and continuity in the scientific realism debate by making perspicuous which concepts are best equipped to evaluate the realist's epistemic claims against the historical record of science.

Along with a well-honoured tradition, we will accept that intentionality is at least a property a thought holds necessarily, i.e., in all possible worlds that contain it; more specifically, a necessary relation, namely the relation of existential dependence of the thought on its intentional object. Yet we will first of all try to show that intentionality is more than that. For we will claim that intentionality is an essential property of the thought, namely a property whose predication to the thought (...) is true in virtue of the identity, or nature, of such a thought. More particularly, for us intentionality will again be a relation, yet a relation of ontological dependence of the thought on its intentional object; specifically, the relation for the thought of being constituted by its object. Moreover, we will try to show that if intentionality is such a constitutive relation for the thought that has it, certain metaphysical consequences ensue. First, an objectual thought, a thought whose content basically consists in its intentional object, is nothing but that object in a certain cogitative modality, or, which is the same, as playing a certain motivational role for the subject entertaining the thought itself (at a certain time). Second, if an objectual thought is nothing but an intentional object in a cogitative modality, such a thought, not only as a type, but also as a token, is an abstract entity. More specifically, an objectual thought-type, an abstract object par excellence, is indeed instantiated by objectual thought-tokens which are again abstract particulars, yet of a specific kind: namely, tropes of a relational sort depending for their existence on their bearers (and possibly also on their temporal location).

According to Donald Davidson, language is social in that only a person who has interacted linguistically with another could have a language. This paper is a discussion of Davidson’s argument in defence of that claim. I argue that he has not succeeded in establishing it, but that he has provided many of the materials out of which a successful argument could be built. Chief among these are the claims that some version of externalism about meaning is true, that possession of (...) a language requires possession of the concept of objectivity, and hence that the issue here concerns the identity of the external event that makes possible possession of the concept of objectivity. I end by presenting some reasons for thinking that only interpersonal linguistic interaction could play this role. (shrink)

The phenomenal properties of conscious mental states happen to be exclusively accessible from the first-person perspective. Consequently, some philosophers consider their existence to be incompatible with materialist metaphysics. In this paper I criticise one particular argument that is based on the idea that for something to be real it must (at least in principle) be accessible from an intersubjective perspective. I argue that the exclusively subjective access to phenomenal contents can be explained by the very particular nature of the epistemological (...) relation holding between a subject and his own mental states. Accordingly, this subjectivity does not compel us to deny the possibility that phenomenal contents are ontologically objective properties. First, I present the general form of the argument that I will discuss. Second, I show that this argument makes use of a criterion of reality that is not applicable to the case of subjective experience. Third, I discuss a plausible objection and give an argument for rejecting observation models of self-knowledge of phenomenal contents. These models fall prey to the homunculus illusion. (shrink)

Investigations of the function of consciousness in human information processing have focused mainly on two questions: (1) where does consciousness enter into the information processing sequence and (2) how does conscious processing differ from preconscious and unconscious processing. Input analysis is thought to be initially "preconscious," "pre-attentive," fast, involuntary, and automatic. This is followed by "conscious," "focal-attentive" analysis which is relatively slow, voluntary, and flexible. It is thought that simple, familiar stimuli can be identified preconsciously, but conscious processing is needed (...) to identify complex, novel stimuli. Conscious processing has also been thought to be necessary for choice, learning and memory, and the organization of complex, novel responses, particularly those requiring planning, reflection, or creativity.

This paper replies to the first 36 commentaries on my target article on “Is human information processing conscious?” (Behavioral and Brain Sciences,1991, pp.651-669). The target article focused largely on experimental studies of how consciousness relates to human information processing, tracing their relation from input through to output, while discussion of the implications of the findings both for cognitive psychology and philosophy of mind was relatively brief. The commentaries reversed this emphasis, and so, correspondingly, did the reply. The sequence of topics (...) in the reply roughly follows that of the target article. The discussion begins with a reconsideration of the details of the empirical findings, whether they can be extrapolated to non-laboratory settings, and the extent to which one can rely on their use of subjective reports. This is followed by an in-depth discussion of what is meant by “conscious processing” and of how phenomenal consciousness relates to attentional processing. We then turn to broader philosophical and theoretical issues. I point out some of the reasons why I do not support epiphenomenalism, dualist-interactionism, or reductionism, and elaborate on how first- and third-person views of the mind can be regarded as complementary and mutually irreducible. I suggest how the relation of conscious experiences to their neural correlates can be understood in terms of a dual-aspect theory of information,and how this might be used to resolve some of the paradoxes surrounding the causal interactions of consciousness and brain. I also suggest that, viewed from a first-person perspective, consciousness gives purpose to existence, which allows a different way of viewing its role in evolution. (shrink)

This article is a critical review of Cocchiarella’s theory of reference. In conceptual realism, there are two central distinctions regarding reference: first, between active and deactivated use of referential expressions, and, second, between using referential expressions with and without existential presupposition. Cocchiarella’s normative restrictions on the existential presuppositions of reference lead to postulating two fundamentally different kinds of objects in conceptual realism: realia or concrete objects, on the one hand, and abstract intensional objects or nonexistents, on the other. According to (...) Cocchiarella, nonexistents can be referred to only without existential presuppositions. However, referring to nonexistents with existential presuppositions is an ordinary human practice. To account for this fact, Cocchiarella’s normative theory of reference should be supplemented by a descriptive account of referring. (shrink)

Kripke has argued that definitions of units of measurements provide examples of statements that are both contingent and a priori. In this paper I argue that definitions of units of measurement are intended to be stipulations of what Kripke calls "theoretical identities": a stipulation that two terms will have the same rigid designation. Hence such a definition is both a priori and necessary. The necessity arises because such definitions appeal to natural kind properties only, which on Kripke's account are necessary.

A standard conception of metaphysical modality accepts that Some de re modal claims are true, These should be understood in terms of a possible worlds semantics, and There is trans-world identity. For instance, it seems true that Humphrey could have won the election. In possible worlds speak, we say that there exists a possible world where Humphrey wins the election. Furthermore, had that possibility been actualized instead of this one, Humphrey—our Humphrey, the very same man—would still have existed. Here, I (...) argue that this way of understanding de re modal claims, in conjunction with certain other plausible assumptions, entails that The World is a necessary being. (shrink)

Modal rationalism includes the thesis that ideal primary positive conceivability entails primary possibility. Modal monism is the thesis that the space of logically possible worlds is coextensive with the space of metaphysically possible worlds. In this paper I explore the relation between the two theses. My aim is to show that the former thesis implies the latter thesis, and that problems with the latter make the former implausible as a complete picture of the epistemology of modality. My argument explores the (...) relation between logical modality and metaphysical modality. (shrink)

We often decide whether a state of affairs is possible by trying to mentally depict a scenario where the state in question obtains . These mental acts seem to provide us with an epistemic route to the space of possibilities. The problem this raises is whether conceivability judgments provide justification-conferring grounds for the ensuing possibility-claims . Although the question has a long history, contemporary interest in it was, to a large extent, prompted by Kripke's utilization of modal intuitions in the (...) course of propounding certain influential theses in the philosophy of language and mind. The interest has been given a further boost by the recent two-dimensional approach to the Kripkean framework. In this paper, I begin by providing a detailed examination of a most recent attempt to defend the thesis and argue that it is unsuccessful. This is followed by presenting my own gloss on Kripke's explanation of the illusions of contingency and I close by raising a general problem intended to undermine the prospects for a successful defense of the thesis.

This work will focus on some aspects of descriptive names. The New Theory of Reference, in line with Kripke, takes descriptive names to be proper names. I will argue in this paper that descriptive names and certain theory in reference to them, even when it disagrees with the New Theory of Reference, can shed light on our understanding of (some) non-existence statements. I define the concept of descriptive name for hypothesised object (DNHO). My thesis being that DNHOs are, as I (...) will specify, descriptions: a proposition expressed by the utterance ‘n is F’, where ‘n’ is a DNHO, is not singular at all; it is a descriptive proposition. To sum up, concerning proper names, the truth lies closer to the New Theory of Reference, but descriptivism is not altogether false. As for DNHOs descriptivism is, in some cases, the right fit.

Metasemantic security arguments aim to show, on metasemantic grounds, that even if we were to discover that determinism is true, that wouldn't give us reason to think that people never act freely. Flew's [1955] Paradigm Case Argument is one such argument; Heller's [1996] Putnamian argument is another. In this paper I introduce a third which uses a metasemantic picture on which meanings are settled as though by an ideal interpreter. Metasemantic security arguments are widely thought discredited by van Inwagen's [1983] (...) Martian Manipulation objection. I argue that van Inwagen's objection, if right, can be parodied to undercut metasemantic arguments which aim to show that deliverances of physics do not tell us that no objects are solid. A diagnosis of where the parody objection breaks down against the pro-solidity argument is then used to resist the objection as applied to the Ideal Interpreter Argument. I go on to defend the argument from the charge that it relies on a ham-fisted version of interpretivism. (shrink)

When you think about a particular object, what makes your thought about that object? Roderick Chisholm, Ernest Sosa and Michael McKinsey have defended 'latitudinarian', 'descriptivist', or what I call 'liberal' answers to that question. In this paper I carefully consider the motivation for these liberal views and show how it extends in unanticipated ways to motivate views that are considerably more liberal.

Many philosophers have attempted to provide a solution to the paradox of fiction, a triad of sentences that lead to the conclusion that genuine emotional responses to fiction are irrational. We suggest that disagreement over the best response to this paradox stems directly from the formulation of the paradox itself. Our main goal is to show that there is an ambiguity regarding the word ‘exist’ throughout the premises of the paradox. To reveal this ambiguity, we display the diverse existential commitments (...) of several leading theories of emotion, and argue that none of the theories we consider are committed to notions of ‘exist’ employed by the paradox. We conclude that it is unclear whether or not there remains a paradox of fiction to be solved—rather than to be argued for—once this ambiguity is addressed. (shrink)

This paper examines Ian Hacking's analysis of the looping effects of psychiatric classifications, focusing on his recent account of interactive and indifferent kinds. After explicating Hacking's distinction between 'interactive kinds' (human kinds) and 'indifferent kinds' (natural kinds), I argue that Hacking cannot claim that there are 'interactive and indifferent kinds,' given the way that he introduces the interactive-indifferent distinction. Hacking is also ambiguous on whether his notion of interactive and indifferent kinds is supposed to offer an account of classifications or (...) objects of classification. I argue that these conceptual difficulties show that Hacking's account of interactive and indifferent kinds cannot be based on - and should be clearly separated from - his distinction between interactive kinds and indifferent kinds. In clarifying Hacking's account, I argue that interactive and indifferent kinds should be regarded as objects of classification (i.e., kinds of people) that can be identified with reference to a law-like biological regularity and are aware of how they are classified. Schizophrenia and depression are discussed as examples. I subsequently offer reasons for resisting Hacking's claim that the objects of classification in the human sciences - as a result of looping effects - are 'moving targets'. (shrink)

That there is an epistemological difference between the mental and the physical is well- known. Introspection readily generates knowledge of one’s own conscious experience, but fails to yield evidence for the existence of anything physical. Conversely, empirical investigation delivers knowledge of physical properties, but neither finds nor requires us to posit conscious experience. In recent decades, a series of neo-Cartesian arguments have emerged that rest on this epistemological difference and purport to demonstrate that mind-brain identity is false and that consciousness (...) is not even realized by or supervenient on physical properties. Where Descartes argued he could clearly and distinctly conceive mind and body as existing separately, contemporary anti-physicalists hold that the conceivability of worlds in which actual world correlations between physical and phenomenological properties fail shows that these correlations are contingent rather than logically or metaphysically necessary. Together with Descartes, they conclude from conceivability that identity, as well as strong supervenience, is false. 1 If the argument of this paper is correct, however, then there is an argument for dualism that arises from the epistemological distinction, is grounded in the Meditations, and is yet distinct from the " 1 " conceivability arguments pursued both by Descartes and contemporary anti-physicalists. Furthermore, the argument is immune to the standard objections to conceivability arguments: its conclusion follows even if there are a posteriori identities between physical and phenomenal properties.

It has been argued that a combination of game-theoretic semantics and independence-friendly (IF) languages can provide a novel approach to the conceptual foundations of mathematics and the sciences. I introduce and motivate an IF first-order modal language endowed with a game-theoretic semantics of perfect information. The resulting interpretive independence-friendly logic (IIF) allows to formulate some basic model-theoretic notions that are inexpressible in the ordinary quantified modal logic. Moreover, I argue that some key concepts of Kripke’s new theory of reference are (...) adequately modeled within IIF. Finally, I compare the logic IIF to David Lewis' counterpart theory, drawing some morals concerning the interrelation between metaphysical and semantic issues in possible-world semantics. (shrink)

Fictional names present unique challenges for semantic theories of proper names, challenges strong enough to warrant an account of names different from the standard treatment. The theory developed in this paper is motivated by a puzzle that depends on four assumptions: our intuitive assessment of the truth values of certain sentences, the most straightforward treatment of their syntactic structure, semantic compositionality, and metaphysical scruples strong enough to rule out fictional entities, at least. It is shown that these four assumptions, taken (...) together, are inconsistent with referentialism, the common view that names are uniformly associated with ordinary individuals as their semantic value. Instead, the view presented here interprets names as context-sensitive expressions, associated in a context of utterance with a particular act of introduction, or dubbing, which is then used to determine their semantic value. Some dubbings are referential, which associate names with ordinary individuals as their semantic values; others are fictional, which associate names, instead, with sets of properties. Since the semantic values of names can be of different sorts, the semantic rule interpreting predication must be complex as well. In the body of the paper, I show how this new treatment of names allows us to solve our original puzzle. I defend the complexity of the semantic predication rule, and address additional worries about ontological commitment. (shrink)

It is often noted that institutional objects and artifacts depend on human beliefs and intentions and so fail to meet the realist paradigm of mind-independent objects. In this paper I draw out exactly in what ways the thesis of mind-independence fails, and show that it has some surprising consequences. For the specific forms of mind-dependence involved entail that we have certain forms of epistemic privilege with regard to our own institutional and artifactual kinds, protecting us from certain possibilities of ignorance (...) and error; they also demonstrate that not all cases of reference to these kinds can proceed along a causal model. As a result, realist views in ontology, epistemology, and semantics that were developed with natural scientific kinds in mind cannot fully apply to the everyday world. In closing I consider some wider consequences of these results for social science and philosophy. (shrink)

This is a reply to Timothy Williamson ’s paper ‘Tennant’s Troubles’. It defends against Williamson ’s objections the anti-realist’s knowability principle based on the author’s ‘local’ restriction strategy involving Cartesian propositions, set out in The Taming of the True. Williamson ’s purported Fitchian reductio, involving the unknown number of books on his table, is analyzed in detail and shown to be fallacious. Williamson ’s attempt to cause problems for the anti-realist by means of a supposed rigid designator generates a contradiction (...) with arithmetic right away, upon instantiating the obviously relevant theorem that every natural number is provably odd or provably even. The paper also explains and formulates a globally restricted knowability principle, which likewise blocks the attempted reductio. (shrink)

The consensus among spacetime substantivalists is to respond to Leibniz's classic shift arguments, and their contemporary incarnation in the form of the hole argument, by pruning the allegedly problematic metaphysical possibilities that generate these arguments. Some substantivalists do so by directly appealing to a modal doctrine akin to anti-haecceitism. Other substantivalists do so by appealing to an underlying hyperintensional doctrine that implies some such modal doctrine. My first aim in this paper is to pose a challenge for all extant forms (...) of this consensus position. My second aim is to show what form substantivalism must take in order to uphold the consensus while addressing this challenge. The result is a novel "plenitudinous" substantivalist view, which predicts that certain modal facts about spacetime are vague or indeterminate. I then argue against this view on independent grounds, concluding that substantivalists should reject the consensus position. The paper also discusses the way forward for substantivalists in light of this conclusion. (shrink)

Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from (...) ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.

The ontology of ‘powerful qualities’ is gaining an increasing amount of attention in the literature on properties. This is the view that the so-called categorical or qualitative properties are identical with ‘dispositional’ properties. The position is associated with C.B. Martin, John Heil, Galen Strawson and Jonathan Jacobs. Robert Schroer ( 2012 ) has recently mounted a number of criticisms against the powerful qualities view as conceived by these main adherents, and has also advanced his own (radically different) version of the (...) view. In this paper I have three main aims: firstly, I shall defend the ontology from his critique, arguing that his criticisms do not damage the position. Secondly, I shall argue that Schroer’s own version of the view is untenable. Thirdly, the paper shall serve to clear up some conceptual confusions that often bedevil the powerful qualities view.

Richard Boyd and Robert Adams have both developed semantic accounts of moral terms based on Hilary Putnam's causal regulation theory for natural kind terms, according to which the terms in question refer to the properties which predominantly causally regulated the terms. However, Terence Horgan and Mark Timmons have mounted an objection to Boyd's semantics—their Moral Twin Earth argument. If this argument is successful against Boyd then it might be thought that it should also be successful against Adams, given the similarity (...) between their semantic accounts. I will argue in this essay that Adams's semantics is sufficiently different from Boyd's to enable him to survive Moral Twin Earth, but that he is vulnerable to a modified version of Moral Twin Earth that I describe.

I argue that mereological nihilism fails because it cannot answer the special arrangement question: when is it true that the xs are arranged F-wise? I suggest that the answers given in the literature fail and that the obvious responses that could be made look to undermine the motivations for adopting nihilism in the first place.

Recent work on Natural Kind Essentialism has taken a deflationary turn. The assumptions about the grounds of essentialist truths concerning natural kinds familiar from the Kripke-Putnam framework are now considered questionable. The source of the problem, however, has not been sufficiently explicated. The paper focuses on the Twin Earth scenario, and it will be demonstrated that the essentialist principle at its core (which I call IDENT)—that necessarily, a sample of a chemical substance, A, is of the same kind as another (...) sample, B, if and only if A and B have the same microstructure—must be re-evaluated. The Twin Earth scenario also assumes the falsity of another essentialist principle (which I call INST): necessarily, there is a 1:1 correlation between (all of ) the chemical properties of a chemical substance and the microstructure of that substance. This assumption will be questioned, and it will be argued that, in fact, the best strategy for defending IDENT is to establish INST. The prospects for Natural Kind Essentialism and microstructural essentialism regarding chemical substances will be assessed with reference to recent work in the philosophy of chemistry. Finally, a weakened form of INST will be presented. (shrink)

This paper challenges the Kripkean interpretation of a posteriori necessities. It will be demonstrated, by an analysis of classic examples, that the modal content of supposed a posteriori necessities is more complicated than the Kripkean line suggests. We will see that further research is needed concerning the a priori principles underlying all a posteriori necessities. In the course of this analysis it will emerge that the modal content of a posteriori necessities can be best described in terms of a Finean (...) conception of modality – by giving essences priority over modality. The upshot of this is that we might be able to establish the necessity of certain supposed a posteriori necessities by a priori means. (shrink)

In this paper I will offer a novel understanding of a priori knowledge. My claim is that the sharp distinction that is usually made between a priori and a posteriori knowledge is groundless. It will be argued that a plausible understanding of a priori and a posteriori knowledge has to acknowledge that they are in a constant bootstrapping relationship. It is also crucial that we distinguish between a priori propositions that hold in the actual world and merely possible, non-actual a (...) priori propositions, as we will see when considering cases like Euclidean geometry. Furthermore, contrary to what Kripke seems to suggest, a priori knowledge is intimately connected with metaphysical modality, indeed, grounded in it. The task of a priori reasoning, according to this account, is to delimit the space of metaphysically possible worlds in order for us to be able to determine what is actual. (shrink)

Machery, Mallon, Nichols, and Stich [2004; forthcoming] use experimental methods to raise a spectre of doubt about reliance on intuitions in developing theories of reference which are then deployed in philosophical arguments outside the philosophy of language. Machery et al. ran a cross-cultural survey asking Western and East Asian participants about a famous case from the philosophical literature on reference (Kripke's G del example). They interpret their results as indicating that there is significant variation in participants' intuitions about semantic reference (...) for that case. We argue that this interpretation is mistaken. We detail a type of ambiguity found in Machery et al.'s probe but not yet noted in the response literature. We argue that this epistemic ambiguity could have affected their results. We do not stop there, however: Rather than rest content with a possibility claim, we ran four studies to test the impact of this ambiguity on participants' responses. We found that this accounts for much of the variation in Machery et al.'s original experiment. We conclude that in the light of our new data, their argument is no longer convincing. (shrink)

Intuition serves a variety of roles in contemporary philosophy. This paper provides a historical discussion of the revival of intuition in the 1970s, untangling some of the ways that intuition has been used and offering some suggestions concerning its proper place in philosophical investigation. Contrary to some interpretations of the results of experimental philosophy, it is argued that generalized skepticism with respect to intuition is unwarranted. Intuition can continue to play an important role as part of a methodologically conservative stance (...) towards philosophical investigation. I argue that methodological conservatism should be sharply distinguished from the process of evaluating individual propositions. Nevertheless, intuition is not always a reliable guide to truth and experimental philosophy can serve a vital ameliorative role in determining the scope and limits of our intuitive competence with respect to various areas of inquiry.

This paper defends (especially in response to Brian Leftow’s recent attack) logical nominalism, the thesis that logically necessary truth belongs primarily to sentences and depends solely on the conventions of human language. A sentence is logically necessary (that is, a priori metaphysically necessary) iff its negation entails a contradiction. A sentence is a posteriori metaphysically necessary iff it reduces to a logical necessity when we substitute for rigid designators of objects or properties canonical descriptions of the essential properties of those (...) objects or properties. The truth-conditions of necessary sentences are not to be found in any transcendent reality, such as God’s thoughts. "There is a God" is neither a priori nor a posteriori metaphysically necessary; God is necessary in the sense that His existence is not causally contingent on anything else. (shrink)

This article discusses some of the ways in which natural language can express modal information – information which is, to a first approximation, about what could be or must be the case, as opposed to being about what actually is the case. It motivates, explains, and raises problems for Angelika Kratzer's influential theory of modal auxiliaries, and introduces a new approach to one important debate about the relationships between modality, evidentiality, context change, and imperative force.

Realist essentialists face a prima facie challenge in accounting for our knowledge of the essences of things, and in particular, in justifying our engaging in thought experiments to gain such knowledge. In contrast, conferralist essentialism has an attractive story to tell about how we gain knowledge of the essences of things, and how thought experiments are a justified method for gaining such knowledge. The conferralist story is told in this essay.

In this article I introduce a certain kind of anti-realist account of what makes a property essential to an object and defend it against likely objections. This account, which I call a ‘conferralist’ account, shares some of the attractive features of other anti-realist accounts, such as conventionalism and expressivism, but I believe, not their respective drawbacks.
