Our reading is a passage from John Locke, An Essay Concerning Human Understanding , Book III, Chapter II, § 2. When a man speaks to another, it is that he may be understood; and the end of speech is that those sounds, as marks, may make known his ideas to the hearer. … Words being voluntary signs, they cannot be voluntary signs imposed by him on things he knows not. That would be to make them signs of nothing, sounds without (...) signification. (shrink)

While engaged in the analysis of topics such as the nature of knowledge, meaning, or justice, analytic philosophers have traditionally relied extensively on their own intuitions about when the relevant terms can, and can't, be correctly applied. Consequently, if intuitions about possible cases turned out not to be a reliable tool for the proper analysis of philosophically central concepts, then a radical reworking of philosophy's (or at least analytic philosophy's) methodology would seem to be in order. It is thus not (...) surprising that the increasingly critical scrutiny that intuitions have received of late has produced what has been referred to as a "crisis" in analytic philosophy. This paper will argue, however, that at least those criticisms that stem from recent work on semantic externalism are not as serious as their proponents have claimed. Indeed, this paper will argue while the conceptual intuitions (and the analyses that result from them) will have to be recognized as fallible, they still have a prima facie claim to correctness. A naturalistic and externalistic account of concepts thus merely requires that the methodology of conceptual analysis be reinterpreted (from a 'Platonic' to a 'constructive' model) rather than given up.

This paper discusses an "expressive constraint" on accounts of thought and language which requires that when a speaker expresses a belief by sincerely uttering a sentence, the utterance and the belief have the same content. It will be argued that this constraint should be viewed as expressing a conceptual connection between thought and language rather than a mere empirical generalization about the two. However, the most obvious accounts of the relation between thought and language compatible with the constraint (giving an (...) independent account of one of either linguistic meaning or thought content and understanding the other in terms of it) both face serious difficulties. Because of this, the following will suggest an alternative picture of the relation between thought and language that remains compatible with the constraint. (shrink)

Functionalism, the philosophical theory that defines mental states in terms of their causal relations to stimuli, overt behaviour, and other inner mental states, has often been accused of being unable to account for the qualitative character of our experimential states. Many times such objections to functionalism take the form of conceivability arguments. One is asked to imagine situations where organisms who are in a functional state that is claimed to be a particular experience either have the qualitative character of that (...) experience altered or absent altogether. Many of these arguments are surprisingly advanced by materialist philosophers. I argue that if the conceivability arguments were successful against functionalism, then they would be successful against their alternative materialist views as well. So the conceivability arguments alone do not provide a good reason for materialists to abandon functionalism. I further argue that functionalism is best understood to be an empirical theory, and if it is so understood then the conceivability arguments have no force against it at all. A further consequence that emerges is that on an empirical functionalist view, qualia, if real, are properties in the domain of psychology. (shrink)

Possible worlds, concrete or abstract as you like, are irrelevant to the truthmakers for modality—or so I shall argue in this paper. First, I present the neo-Humean picture of modality, and explain why those who accept it deny a common sense view of modality. Second, I present what I take to be the most pressing objection to the neo-Humean account, one that, I argue, applies equally well to any theory that grounds modality in possible worlds. Third, I present an alternative, (...) properties-based theory of modality and explore several specific ways to flesh the general proposal out, including my favored version, the powers theory. And, fourth, I offer a powers semantics for counterfactuals that each version of the properties-based theory of modality can accept, mutatis mutandis. Together with a definition of possibility and necessity in terms of counterfactuals, the powers semantics of counterfactuals generates a semantics for modality that appeals to causal powers and not possible worlds.

I argue that Millianism has the very odd consequence that there are simple direct questions that Millians can grasp, but they cannot answer them in the positive or the negative, or in some other way, nor could they say that they do not know the answer.

What does it mean for a general term to be rigid? It is argued by some that if we take general terms to designate their extensions, then almost no empirical general term will turn out to be rigid; and if we take them to designate some abstract entity, such as a kind, then it turns out that almost all general terms will be rigid. Various authors who pursue this line of reasoning have attempted to capture Kripke’s intent by defining a (...) rigid general term as one that applies to the objects in its extension essentially. I argue that this account is significantly mistaken for various reasons: it conflates a metaphysical notion (essentialism) with a semantic one (rigidity); it fails to countenance the fact that any term can be introduced into a language by stipulating that it be a rigid designator; it limits the extension of rigid terms so much that terms such as ‘meter’, ‘rectangle’, ‘truth’, etc. do not turn out to be rigid, when they obviously are; and it wrongly concentrates on the predicative use of a general term in applying a certain test offered by Kripke to determine whether a term is rigid.

What sorts of things are the intuitions generated via thought experiment? Timothy Williamson has responded to naturalistic skeptics by arguing that thought-experiment intuitions are judgments of ordinary counterfactuals. On this view, the intuition is naturalistically innocuous, but it has a contingent content and could be known at best a posteriori. We suggest an alternative to Williamson's account, according to which we apprehend thought-experiment intuitions through our grasp on truth in fiction. On our view, intuitions like the Gettier intuition are necessarily (...) true and knowable a priori. Our view, like Williamson's, avoids naturalistic skepticism. (shrink)

This paper will articulate and defend a novel theory of epistemic justification; I characterize my view as the thesis that justification is potential knowledge . My project is an instance of the ‘knowledge-first’ programme, championed especially by Timothy Williamson. So I begin with a brief recapitulation of that programme.

Against the forces of modal ersatzism Lewis launches a variety of attacks, some of which are clearly compelling, others of which are less so. I argue that pictorial ersatzism cannot clearly be distinguished from magical ersatzism, and--more interestingly--that 'genuine' modal realism is subject to precisely the criticisms so fatal for the magical ersatzers.

Information Centrism is the view that contexts consist of information that can be characterized in terms of the propositional attitudes of the conversational participants. Furthermore, it claims that this notion of context is the only one needed for linguistic theorizing about context-sensitive languages. We argue that Information Centrism is false, since it cannot account correctly for facts about truth and reference in certain cases involving indexicals and demonstratives. Consequently, contexts cannot be construed simply as collections of shared information.

Argument for fatalism attempts to prove that free choice is a logical or conceptual impossibility. The paper argues that the first two premises of the argument are sound: propositions are either true or false and they have their truth-value eternally. But the claim that from the fatalistic premises with the introduction of some innocent further premise dire consequences follow as regards to the possibility of free choice is false. The introduced premise, which establishes the connection between the first two premises (...) (which are about the nature of propositions) and the concept of free choice is not innocent. It creates the impression that the truth of certain propositions can somehow determine the occurrence of certain events. But no proposition can have such an effect since the counterfactuals If proposition P were true, event E would happen does not say anything about determination. The argument for fatalism is, however, not a boring sophism. It does reveal something about the nature of propositional representation. It shows that each proposition represents necessarily the fact what it represents, i.e. it shows that propositions have their truth conditions non-contingently. But from this nothing follows as regards to the contingent nature of the facts represented. On the bases of the first two premises of the argument for fatalism we cannot infer to the impossibility of free choice. The argument for fatalism should not be interpreted as an attempt to prove on purely logical or conceptual grounds that we do not have the ability to influence future events by our choices. But it could be used to show something about the nature of propositional representation. (shrink)

Widescopism, as I call it, holds that names are synonymous with descriptions that are required to take wide scope over modal adverbs. Scott Soames has recently argued that Widescopism is false. He identifies an argument that is valid but which, he claims, a defender of Widescopism must say has true premises and a false conclusion. I argue, first, that a defender of Widescopism need not in fact say that the target arguments conclusion is false. Soames argument that she must confuses, (...) I claim, modal adverbs and modal predicates. I then argue that even if she did reject the conclusion, she could nonetheless hold that the target arguments first premise is ambiguous as between a true reading, on which the argument is invalid, and a false reading, on which the argument is valid. I conclude that Soames argument against Widescopism fails. (shrink)

Sensitivity to the extra-linguistic context, as exhibited by indexical and demonstrative expressions, and sensitivity to the linguistic context, as exhibited by, for example, anaphoric uses of third person pronouns, are regularly regarded as different and independent phenomena. The data on indexicals, demonstratives, and third person pronouns, however, call for a more unified notion of context and of context sensitivity. This paper aims to develop such a unified picture by generalizing the notion of anaphora to encompass extra-linguistic context dependency and generalizing (...) the notion of a structured discourse context so that contexts contain antecedents for expressions that refer to entities in the extra-linguistic context.

This paper questions the form and prospects of “extended theories” which have been simultaneously and independently advocated both in the philosophy of mind and in the philosophy of biology. It focuses on Extend Mind Theory (EMT) and Developmental Systems Theory (DST). It shows first that the two theories vindicate a parallel extension of received views, the former concerning extending cognition beyond the brain, the latter concerned with extending evolution and development beyond the genes. It also shows that both arguments rely (...) on the demonstration of causal parities, which have been undermined by the classical received view. Then I question whether the argument that there is an illegitimate inference from parities or coupling to constitution claims, which has been objected by Adams and Aizawa in The bounds of cognition, (2008) to EMT, also holds against DST. To this aim, I consider two defenses against DST that are parallel to two defenses against EMT, one about intrinsic content, the other about the difference between what’s in principle possible and what happens in practice. I conclude by claiming that the weaknesses and strengths of both theories are different regarding these two kinds of objections. (shrink)

This article considers the question whether belief ascriptions exhibit context dependence. I first distinguish two potential forms of context dependence in belief ascription. Propositional context dependence concerns what the subject believes, whereas attitudinal context dependence concerns what it is to believe a proposition. I then discuss three potential sources of PCD and two potential sources of ACD. Given the nature of this article, my discussion will provide only an overview of these various forms and sources of context dependence. Along the (...) way I will identify areas where continued research is needed. (shrink)

Alik Pelman proposes a sceptical challenge to the widely accepted thesis that theoretical identities are necessary. His argument relies on the possibility of the manifest criterion of identity. In this article, we argue that given the necessity of the obtaining of the identity criterion, Pelman’s sceptical argument against the necessity of theoretical identities cannot be effective. By comparing Pelman’s sceptical argument with classical sceptical arguments, it is demonstrated that there is a sense in which classical arguments are effective but not (...) Pelman’s. (shrink)

I argue that mental descriptivism cannot be reasonably thought superior to rival theories on the grounds that it can (while they cannot) provide an elegant account of reference failure. Descriptivism about the particular-directed intentionality of our mental states fails when applied to desires. Consider, for an example, the desire that Satan not tempt me. On the descriptivist account, it looks like my desire would be fulfilled in conditions in which there exists exactly one thing satisfying some description only Satan satisfies (...) (call it the Satanic Description). However, against this analysis, it is clearly compatible with desiring that Satan not tempt me that I also desire that there exist nothing satisfying the Satanic Description. The descriptivist has room for maneuver here, but the cost of accommodating this phenomenon is that the descriptivist shall no longer be able to use her theory to ameliorate the possibility of reference failure. (shrink)

Seven proposed accounts of epistemic possibility are criticized, and a new account is proposed, making use of the notion of having justification for dismissing a proposition. The new account explains intuitions about otherwise puzzling cases, upholds plausible general principles about epistemic possibility, and explains the practical import of epistemic modality judgements. It is suggested that judgements about epistemic possibility function to assess which propositions are worthy of further inquiry.

This paper explores the prospects of a combinatorial account of modality. We argue against David M. Armstrong’s version of combinatorialism, which seeks to do without modal primitives, on the grounds, among other things, that Armstrong’s basic ontological categories are themselves subject to non-contingent constraints on recombination. We outline an alternative version, which acknowledges the necessity of modal primitives, at the level of ontology, and not just of our concepts.

In recent years two‐dimensional semantics has become one of the most serious alternatives to Millianism for the proper interpretation of modal discourse. It has origins in the works of a diverse group of philosophers, and it has proven popular as an interpretation of both language and thought. It has probably received most of its attention, however, because of its use by David Chalmers in his arguments against materialism. It is this more metaphysical application of two‐dimensionalism that is the concern in (...) this paper. For though there is probably something salvageable from two‐dimensionalism as a way to explain the content of thought, as a metaphysical tool it should be abandoned. In this paper I aim to establish this point by reductio: if ‘metaphysical’ two‐dimensionalism is assumed, it can be shown to be false. (shrink)

Both a priori physicalism and a posteriori physicalism combine a metaphysical and an epistemological thesis. They agree about the metaphysical thesis: our world is wholly physical. Most agree that this requires everything that there is must be necessitated by the sort of truths described by physics. If we call the conjunction of the basic truths of physics P, all physicalists agree that P entails for any truth Q. Where they disagree is whether or not this entailment can be known a (...) priori. The a priori physicalist says it can, the a posteriori physicalist says it cannot. Though a posteriori physicalism is probably the dominant view, it is really a surprising and somewhat unlikely stance. In this article, the nature of the view is discussed, and two arguments are presented that should cause us to look again at the potential of a priori physicalism. (shrink)

This article presents the knowledge argument against physicalism and objections to it. The focus is on the ways responses to that argument have tried to account for phenomenal knowledge within a physicalist picture. Various ‘phenomenal concepts’ strategies are considered, along with recent arguments against them. Also considered are attempts to explain phenomenal knowledge in terms of indexical knowledge and in terms of acquaintance.

This paper explores a distinction between two types of response- dependence (RD) account (shallow vs. deep). This distinction is inherent in much of the existing literature, however it is neither widely nor well understood, and has never been drawn explicitly. The distinction is often taken to be a metaphysical, or ‘realism-relevant’ one—i.e. deep RD accounts entail qualified realism (or perhaps anti-realism), while shallow RD accounts are metaphysically neutral. I argue that the distinction is not reliably realism-relevant. I formulate a weaker (...) version of the distinction that may help prevent some common and understandable confusion about RD biconditionals and their relationship to realism. The weaker distinction rests on the different roles assigned to RD biconditionals by the two types of account. (shrink)

Self-Knowledge and Self-Reference is a defense and reconciliation of the two apparently conflicting theses that the self is peculiarly elusive and that our basic, cogito-judgments are certain. On the one hand, Descartes seems to be correct that nothing is more certain than basic statements of self-knowledge, such as "I am thinking." On the other hand, there is the compelling Humean observation that when we introspect, nothing is found except for various "impressions." The problem, then, is that the Humean and Cartesian (...) insights are both initially appealing, yet they appear to be in tension with one another. In this paper I attempt to satisfy both intuitions by developing a roughly descriptivist account of self-reference according to which our certainty in basic beliefs stems precisely from our needing to know so little in order to have them. (shrink)

Kant famously argued that, from experience, we can only learn how something actually is, but not that it must be so. In this paper, I defend an improved version of Kant's argument for the existence of a priori knowledge, the Modal Argument , against recent objections by Casullo and Kitcher. For the sake of the argument, I concede Casullo's claim that we may know certain counterfactuals in an empirical way and thereby gain epistemic access to some nearby, nomologically possible worlds. (...) But I maintain that our beliefs about metaphysical necessities still cannot be justified empirically. Furthermore, I reject Casullo's deflationary thesis about the significance of such justification. Kitcher's most troublesome objection is that we can gain any modal justification whatsoever through testimony , i.e. in an experiential way. This can be countered by distinguishing between productive sources of justification, like perception, and merely reproductive sources, like testimony. Thus, some productive a priori source will always be needed somewhere. (shrink)

To sum up, then, both kinds of Putnam's arguments established externalism, though they suffer from several defects. Yet, I think Searle's discussion of these arguments contributes to our understanding of what makes externalism true, and forces us to accept a moderate version of externalism. Searle's own account of the TE story shows us, within a solipsistic outline, how two identical mental states can be directed towards different objects, and further, that the content-determination of indexical thoughts does not necessarily involve external (...) factors. We are thus led to search elsewhere (i.e., not in the nature of indexical thoughts nor in the mere fact of there being identical thoughts with different intentionalities) for what makes the thoughts in question ‘external’. Searle formulates the thesis that intension determines extension as asserting that intension sets certain conditions that anything has to meet in order to fall under its extension. I showed that this is a trivial and implausible understanding of that thesis. Yet, it leads us to distinguish between an intension's setting conditions for falling under its extension and its fully determining such conditions, and thus to see in what sense externalism is true: in the sense that there are intensions that do not fully determine the conditions for falling under their extensions. Rather, they leave indeterminacies. This version of externalism is a moderate one, since though the intensions do not fully determine extensions, they, so to speak, determine their indeterminacies, by specifying the possible external facts that can complete the determination of extension. (The intensions, as I said, function like open sentences, and can be viewed as narrow contents.) So what's in the head plays a much more important role in determining content than Putnam takes it to play. Searle's pointing out that Hilary's concepts ‘elm’ and ‘beech’ are different also contributes to seeing this phenomenon: we realize that in that case the difference between the concepts is what is responsible for the fact that the completions of the extension-determinations are different. I think that this way of viewing the facts shows that ‘the externalist turn’ is not a great revolution, and that with the help of the concept of narrow content we can accept it without abandoning the traditional views about the mind as the source of content, and without being embarrassed by the very idea of (realistic) belief-desire psychology. (shrink)

I argue for three principle claims. First, philosophers who seek to integrate the semantic and the intentional into a naturalistic metaphysical worldview need to address a task that they have thus far largely failed even to notice: explaining into- level connections between the physical and the intentional in a naturalistically acceptable way. Second, there are serious reasons to think that this task cannot be carried out in a way that would vindicate realism about intentionality. Third, there is much to be (...) said for an irrealist, non-eliminativist, naturalistic approach to intentionality that I call "preservative irrealism". (shrink)

Most contemporary philosophers of mind claim to be in search of a 'naturalistic' theory. However, when we look more closely, we find that there are a number of different and even conflicting ideas of what would count as a 'naturalization' of the mind. This article attempts to show what various naturalistic philosophies of mind have in common, and also how they differ from one another. Additionally, it explores the differences between naturalistic philosophies of mind and naturalisms found in ethics, epistemology, (...) and philosophy of science. Section 1 introduces a distinction between two types of project that have been styled 'naturalistic', which I call philosophical naturalism and empirical naturalism . Sections 2 to 6 canvass different strands of philosophical naturalism concerning the mind, followed by a much briefer discussion of attempts to provide empirical naturalizations of the mind in Section 7 . Section 8 concludes the essay with a consideration of the relations between philosophical and empirical naturalism in philosophy of mind, arguing that at least some types of philosophical naturalism are incompatible with empirical naturalism.

I investigate what it means to have an interpretation of our language, how we manage to bestow a determinate interpretation to our utterances, and to which extent our interpretation of the world is determinate. All this is done in dialogue with van Fraassen's insightful discussion of Putnam's model-theoretic argument and of scientific structuralism.

There is a line of reasoning in metaepistemology that is congenial to naturalism and hard to resist, yet ultimately misguided: that knowledge might be a natural kind, and that this would undermine the use of conceptual analysis in the theory of knowledge. In this paper, I first bring out various problems with Hilary Kornblith’s argument from the causal–explanatory indispensability of knowledge to the natural kindhood of knowledge. I then criticize the argument from the natural kindhood of knowledge against the method (...) of conceptual analysis in the theory of knowledge. A natural motivation for this argument is the following seemingly plausible principle: if knowledge is a natural kind, then the concept of knowledge is a natural kind concept. Since this principle lacks adequate support, the crucial semantic claim that the concept of knowledge is a natural kind concept must be defended in some more direct way. However, there are two striking epistemic disanalogies between the concept of knowledge and paradigmatic natural kind concepts that militate against this semantic claim. Conceptual analyses of knowledge are not affected by total error, and the proponents of such analyses are not subject to a priori conceptual obliviousness. I conclude that the argument from natural kindhood does not succeed in undermining the use of conceptual analysis in the theory of knowledge. (shrink)

Pejoratives are the class of expressions that are meant to insult or disparage. They include swear words and slurs. These words allow speakers to convey emotional states beyond the truth-conditional contents that they are normally taken to encode. The puzzle arises because, although pejoratives seem to be a semantically unified class, some of their occurrences are best accounted for truth-conditionally, while others are best accounted for non-truth-conditionally. Where current, non-truth-conditional, views in the literature fail to provide a unified solution for (...) the puzzle, this paper motivates a novel, semantic, analysis of pejorative language. The significance of the proposed solution is not only linguistic in nature, but also philosophical, as it both provides a new argument for, and sheds further light on, the nature of semantic externalism.

A popular defense of physicalist theories of consciousness against anti-physicalist arguments invokes the existence of ‘phenomenal concepts’. These are concepts that designate conscious experiences from a first person perspective, and hence differ from physicalistic concepts; but not in a way that precludes co-referentiality with them. On one version of this strategy phenomenal concepts are seen as (1) type demonstratives that have (2) no mode of presentation. However, 2 is possible without 1-call this the ‘bare recognitional concept’ view-and I will argue (...) that this avoids certain recent criticisms while retaining the virtue of finessing the ‘mode of presentation’ problem for phenomenal concepts. But construing phenomenal concepts this way seems to not do justice to the phenomenology of conscious experience. In this paper I examine whether or not this impression can be borne out by a good argument. As it turns out, it is harder to do so than one might think. It can be done, but it involves somewhat more convoluted reasoning than one might have supposed necessary. Having shown that, I will end with a few brief remarks on what my argument means for attempts to preserve a physicalist account of consciousness. (shrink)

The Paradox of the Surprise Examination has been a testing ground for a variety of frameworks in formal epistemology, from epistemic logic to probability theory to game theory and more. In this paper, I treat a related paradox, the Paradox of the Undiscoverable Position, as a test case for the possible-worlds style representation of epistemic states. I argue that the paradox can be solved in this framework, further illustrating the power of possible-worlds style modeling. The solution also illustrates an important (...) distinction between anti-performatory and unassimilable announcements of information. (shrink)

According to the Principle of the Fixity of the Past (FP), no one can now do anything that would require the past to have unfolded differently than it actually did, for the past is fixed, over and done with. Why might doing something in the future require the past to be different? Because if determinism is true—if the laws of nature and the initial conditions of the Big Bang determined a unique future for our universe—then doing anything other than what (...) you are determined to do would require one of two things: either a miracle, a violation of the actual laws of nature, or a different past, all the way back to the Big Bang or beyond. Which would it be? Those who reject miracles accept a Backtracking Principle (BT), according to which the past would (have to) be different. If this is correct, then it follows by (FP) that you cannot now do anything other than what you are determined to do. The conclusion of this much-discussed argument is that the freedom to do otherwise is incompatible with determinism. In order to break a stalemate between incompatibilists and compatibilists in the debate over (FP), this article presents a new Action-Type Argument for (FP). The aim is to refute Backtracking Compatibilism, the view that (BT) is true and yet the freedom to do otherwise is compatible with determinism. The form of the Action-Type Argument for (FP) also leads to a Simple Argument for incompatibilism, which does not assume (BT). What the Simple Argument does assume is a “governing” view of laws of nature, a view of laws as more than mere regularities that turn out to be exceptionless over all time. Incompatibilism follows.

Frank Jackson formulated his knowledge argument as an argument for dualism. In this paper I show how the argument can be modified to also establish the irreducibility of the secondary qualities to the properties of physical theory, and ultimately "secondary quality eliminativism"- the view that the secondary qualities are physically uninstantiated.

Is it rational to believe that the mind is identical to the brain? Identity theorists say it is (or looks like it will be, once all the neuroscientific evidence is in), and they base this claim on a general epistemic route to belief in identity. I re-develop this general route and defend it against some objections. Then I discuss how rational belief in mind–brain identity, obtained via this route, can be threatened by an appropriately adjusted version of the anti-physicalist knowledge (...) argument. Responses to this threat usually appeal either to different modes of presentation or to phenomenal concepts. But neither type of response is satisfactory. I provide a novel response, which appeals to an innocuous epistemic peculiarity of phenomenal states, namely their, as I shall call it, evidential insulation. (shrink)

Let an X/Y distinction be a distinction between kinds of properties, such as the distinctions between qualitative and non-qualitative, intrinsic and extrinsic, perfectly natural and less-than-perfectly natural or dispositional and categorical properties. An X/Y distinction is hyperintensional iff there are cointensional properties P and Q, such that P is an X-property, whereas Q is a Y-property. Many accounts of metaphysical distinctions among properties presuppose that such distinctions are non-hyperintensional. In this paper, I call this presupposition into question. I develop a (...) sufficient condition for the hyperintensionality of X/Y distinctions and argue that this condition is satisfied by a number of standard classifications of properties. It follows that non-hyperintensional analyses of distinctions among properties are harder to defend than is often assumed. (shrink)
