The notion of rigidity looms large in philosophy of language, but is beset by difficulties. This paper proposes a simple theory of rigidity, according to which an expression has a world-relative semantic property rigidly when it has that property at, or with respect to, all worlds. Just as names, and certain descriptions like The square root of 4, rigidly designate their referents, so too are necessary truths rigidly true, and so too does cat rigidly have only animals in its extension. (...) After spelling out the theory, I argue that it enables us to avoid the headaches that attend the misbegotten desire to have a simple rigid/non-rigid distinction that applies to expressions, giving us a simple solution to the problem of generalizing the notion of rigidity beyond singular terms.

There is a line of thought, neglected in recent philosophy, according to which a priori knowable truths such as those of logic and mathematics have their special epistemic status in virtue of a certain tight connection between their meaning and their truth. Historical associations notwithstanding, this view does not mandate any kind of problematic deflationism about meaning, modality or essence. On the contrary, we should be upfront about it being a highly debatable metaphysical idea, while nonetheless insisting that it be (...) given due consideration. From this standpoint, I suggest that the Finean distinction between essence and modality allows us to refine the view. While liberal about meaning, modality and essence, the view is not without bite: it is reasonable to suppose that it is able to ward off philosophical confusions stemming from the undue assimilation of a priori to empirical knowledge.

This paper examines the logic of fictions within fictions. I argue that consistently nested consistent fictions must have certain formal characteristics. The most important is that they form a tree structure. Depending on one’s theory of fictional objects, additional constraints may apply regarding the appearance of a fictional object in two or more fictional universes. The background motivation for the paper is to use iterated fiction operators as a tool for making sense of iterated modal operators; I conclude by noting (...) briefly where the results about nested fictions can, and where they cannot, be extended to nested possible worlds.

We are very grateful to our critics for their kind words and thoughtful engagementwith The Reference Book (hereafter TRB), and also to the editors of Mind & Language for the opportunity to respond. We’ll start our reply by sketching the book’s positive thesis about specific noun phrases and names. In §2 we’ll relate the traditional semantic category we call ‘reference’ to semantic taxonomies given in terms of mechanisms of denotation. In §3, we’ll turn to acquaintance constraints on reference and singular (...) thought. And in §4, we’ll briefly address McGilvray’s and Devitt’s general doubts about the project of truth-conditional semantics to which our book contributes. (shrink)

The so-called missing explanation argument, put forward by Mark Johnston in the late 80’s purported to show that our ordinary concepts of secondary qualities such as the colours cannot be response-dependent. A number of flaws were soon found in the argument. Partly in response to the criticism directed at the original argument, Johnston presented a new version in 1998. In this paper I show that the new version fails, too, for a simple reason: the kind of explanation which Johnston claims (...) to be incompatible with a response-dependent account of the relevant concept is not an empirical explanation at all, but merely looks like one because of certain factors in Johnston’s stage- setting for the argument.

It is generally assumed that rigidity plays a key role in explaining the necessary a posteriori status of identity statements, both between proper names and between natural kind terms. However, while the notion of rigid designation is well defined for singular terms, there is no generally accepted definition of what it is for a general term to be rigid. In this paper I argue that the most common view, according to which rigid general terms are the ones which designate the (...) same kind in all possible worlds, fails to deliver a posteriori necessities. I also present an alternative view, on which the work of explaining a posteriori necessities is not done by rigidity, but by a related metasemantic notion, which I call actuality - dependence.

Causal theories of reference for natural kind terms are widely agreed to play a central role in arguments for the claim that theoretical identity statements such as “Water is H2O” are necessary, if true. However, there is also fairly wide-spread agreement, due to the arguments of Nathan Salmon, that causal theories of reference do not alone establish such essentialism about natural kinds: an independent, non-trivial essentialist premise is also needed. In this paper I will question this latter agreement. I will (...) argue that there is an independently attractive explanation of why such identity statements are metaphysically necessary, if true: an explanation which relies on assumptions about the semantics of natural kind terms, general philosophical assumptions about reference, and straightforward empirical assumptions, but presupposes no non-trivial essentialist premises.

What is it for a predicate or a general term to be a rigid designator? Two strategies for answering this question can be found in the literature, but both run into severe difficulties. In this paper, it is suggested that proper names and the usual examples of rigid predicates share a semantic feature which does the theoretical work usually attributed to rigidity. This feature cannot be equated with rigidity, but in the case of singular terms this feature entails their rigidity, (...) as understood in the standard characterisation. Hence, it is appropriate to call this feature proto-rigidity. (shrink)

The problem of masking is widely regarded as a grave threat to the conditional analysis of dispositions. Unlike the difficulty arising in connection with finkish situations, the problem does not involve the (dis)appearance of a disposition upon the arrival of its activating conditions. Consequently, some promising responses to the finkish cases, in particular David Lewis's reformed analysis, are ill-equipped to deal with masks. I contend that the difficulty posed by masks can be surmounted by supplementing the counterfactual at the heart (...) of the conditional analysis with a ceteris paribus clause. In spelling out this idea, I first examine the issue of provisos in nomic statements. Then I show how the employment of the ceteris paribus clause escapes the objections that are often raised against it, including the charge that the clause cannot informatively capture all the possible masks of a disposition. (shrink)

It is agreed on all hands that the original version of the conditional analysis of dispositions is defeated by so-called finks and maskers. Some have responded to this predicament by contending that the counterfactual on the right-hand side of the analysis should be expected to hold only when the property it purports to describe is in normal conditions. The essay argues that at the end of the day this idea must presuppose that one is able to arrive at specific descriptions (...) of the factors interfering with the manifestation of a disposition, which calls into question its utility.

Theorists analyzing the concepts of race and gender disagree over whether the terms refer to natural kinds, social kinds, or nothing at all. The question arises: what do we mean by the terms? It is usually assumed that ordinary intuitions of native speakers are definitive. However, I argue that contemporary semantic externalism can usefully combine with insights from Foucauldian genealogy to challenge mainstream methods of analysis and lend credibility to social constructionist projects.

This article contends that the central principle of modern philosophy is obscured by a side-debate between two opposed camps that are united in accepting a deeper flawed premise. Consider the powerful critiques of Kantian philosophy offered by Quentin Meillassoux and Bruno Latour, respectively. These two thinkers criticize Kant for opposite reasons: Meillassoux because Kant collapses thought and world into a permanent “correlate” without isolated terms, and Latour because Kant tries to purify thought and world from each other rather than realizing (...) that they are always combined in “hybrid” form. What both critiques tacitly accept is the notion that “thought” and “world” are the two major poles of the universe. I claim that this stems from the post-Cartesian assumption that thought and world are the two basic kinds of things that exist. The name “onto-taxonomy” is introduced for this view. (shrink)

In this paper, I argue, contra Perry, that the existence of locating beliefs does not require the abandonment of the analysis of belief as a relation between subjects and propositions. I argue that what the "problem of the essential indexical" reveals is that a complete explanation of behaviour requires both an explanation of the type of behaviour the agent engaged in and an explanation of why she engaged in it in the circumstances that she did. And I develop an account (...) of belief which encompasses both explanatory roles and which still treats belief as a two-place relation between subjects and propositions. (shrink)

Manuel DeLanda is one of the few admitted realists in present-day continental philosophy, a position he claims to draw from Deleuze. DeLanda conceives of the world as made up of countless layers of assemblages, irreducible to their parts and never dissolved into larger organic wholes. This article supports DeLanda’s position as a refreshing new model for continental thought. It also criticizes his movement away from singular individuals toward disembodied attractors and topological structures lying outside all specific beings. While endorsing DeLanda’s (...) realism, I reject his shift from the actual to the virtual. (shrink)

This article argues, against contemporary experimentalist criticism, that conceptual analysis has epistemic value, with a structure that encourages the development of interesting hypotheses which are of the right form to be valuable in diverse areas of philosophy. The article shows, by analysis of the Gettier programme, that conceptual analysis shares the proofs and refutations form Lakatos identified in mathematics. Upon discovery of a counterexample, this structure aids the search for a replacement hypothesis. The search is guided by heuristics. The heuristics (...) of conceptual analysis are similar to those in other interesting areas of scholarship, and so hypotheses generated by it are of the right form to be applicable to diverse areas. The article shows that the explanationist criterion in epistemology was developed and applied in this way. The epistemic value of conceptual analysis is oblique because it contributes not towards the main purpose of conceptual analysis but towards the reliable development of epistemically valuable hypotheses in philosophy and scholarship.

At least Kant thinks it's a part of the concept that gold is to be a yellow metal. He thinks that we know this a priori, and that we could not discover it to be empirically false … Is Kant right about this? Gold [is] … a yellow malleable ductile high density metallic element resistant to chemical reaction. Nature considered materially is the totality of all objects of experience. Kant's joke. Kant wanted to prove in a way that would dumbfound (...) the common man that the common man was right: that was the secret joke of this soul. (shrink)

In this paper I answer Aranyosi’s (Axiomathes 19(2):223–224, 2009) criticism of my “Is Phosphorus Hesperus?” (Axiomathes 19(1):101–102, 2009).

Can institutional objects be identified with physical objects that have been ascribed status functions, as advocated by John Searle in The Construction of Social Reality (1995)? The paper argues that the prospects of this identification hinge on how objects persist – i.e., whether they endure, perdure or exdure through time. This important connection between reductive identification and mode of persistence has been largely ignored in the literature on social ontology thus far.

Some hold that if we can imagine God creating a world in which a particular proposition (p) is true, then we can conclude that p is possible. I argue that such appeals to God can’t provide us with a guide to possibility. For either God’s powers aren’t co-extensive with the possible or they are. And if they are, these appeals either beg the question or court a version of Euthyphro’s Dilemma. Some may argue that such appeals were only intended to (...) prompt us to think broadly about the modal claim at issue. I argue instead that these appeals must be understood as more than mere prompts. For it is these appeals that would, if successful, render the conceivability principle viable. (shrink)

We argue that Recanati burdens his otherwise salutary “Mental File” account of singular thought with an “Actualist” assumption that he has inherited from the discussion of singular thought since at least Evans, according to which singular thoughts can only be about actual objects: apparent singular thoughts involving “empty” terms lack truth-valuable content. This assumption flies in the face of manifestly singular thoughts involving not only fictional and mistakenly postulated entities, such as Zeus and the planet Vulcan, but also “perceptual inexistents,” (...) e.g., Kanizsa figures, rainbows, words and phonemes, as well as hosts of at best metaphysically problematic “objects,” such as properties, numbers, ceremonies, contracts, symphonies, “the sky,” “the rain.” Indeed, reflection on what seems to be the boundless diversity of “things” about which we seem to be able to have singular thoughts strongly suggests that there may be no general metaphysics of objects, much less “acquaintance” and “epistemically rewarding” relations that would distinguish singular from non-singular thought. We recommend that Recanati and other mental file theorists confine the theory to a metaphysically neutral account of singular thought as specific kind of internally “focused” computational state, and not seek any general account of the relation of thought to reality.

This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic (...) theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can, though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence” some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology of persistence—are revealed.

David Chalmers supports his contention that there is a possible world populated by our zombie twins by arguing for the assumption that conceivability entails possibility. But, I argue, the modal epistemology he sets forth, ‘modal rationalism,’ ignores the problem of incompleteness and relies on an idealized notion of conceivability. As a consequence, this epistemology can’t justify our quotidian judgments of possibility, let alone those judgments that concern the mind/body connection. Working from the analogy that the imagination is to the possible (...) as perception is to the actual, I set forth a competing epistemology, ‘modal empiricism.’ This epistemology survives the incompleteness objection and allows some of our everyday modal judgments to be justified. But this epistemology can’t justify the claim that Zombie World is possible, which leaves Chalmers’s property dualism without the support it needs. (shrink)

The traditional view that all logical truths are metaphysically necessary has come under attack in recent years. The contrary claim is prominent in David Kaplan’s work on demonstratives, and Edward Zalta has argued that logical truths that are not necessary appear in modal languages supplemented only with some device for making reference to the actual world (and thus independently of whether demonstratives like ‘I’, ‘here’, and ‘now’ are present). If this latter claim can be sustained, it strikes close to the (...) heart of the traditional view. I begin this paper by discussing and refuting Zalta’s argument in the context of a language for propositional modal logic with an actuality connective (section 1). This involves showing that his argument in favor of real world validity his preferred explication of logical truth, is fallacious. Next (section 2) I argue for an alternative explication of logical truth called general validity. Since the rule of necessitation preserves general validity, the argument of section 2 provides a reason for affirming the traditional view. Finally (section 3) I show that the intuitive idea behind the discredited notion of real world validity finds legitimate expression in an object language connective for deep necessity. (shrink)

We examine a crucial question for the World Wide Web: What does a Uniform Resource Identifier (URI) mean? Crucial for the next-generation Semantic Web, can it refer to things outside web-pages? The Web is a universal information space for naming and accessing information via URIs. However, the classical philosophical problems of meaning and reference that have been the source of debate within the philosophy of language return when the Web is given as the foundation for a knowledge representation with the (...) Semantic Web. Debates on the Semantic Web about the meaning and referential status of a URI are explored as analogues to debates about the meaning and reference of names in the philosophy of language. Three main positions are inspected: the logical position, as exemplified by the descriptivist theory of reference, the direct reference position, as exemplified by Putnam and Kripke’s causal theory of reference, and a Wittgensteinian position that views URIs as a public language, as exemplified by Web search engines. These positions show that debates within the philosophy of language are alive and well on the Web, and so in the philosophy of computer science. (shrink)

Can the physicalist consistently hold that representational content is all there is to sensory experience and yet that two perceivers could have inverted phenomenal spectra? Yes, if he holds that the phenomenal properties the inverts experience are dummy properties, not instantiated in the physical objects being perceived nor in the perceivers.

There is evidence that children learn both proper names and count nouns from the outset of lexical development. Furthermore, children's first proper names are typically words for people, whereas their first count nouns are commonly terms for other objects, including artifacts. I argue that these facts represent a challenge for two well-known theoretical accounts of object word learning. I defend an alternative account, which credits young children with conceptual resources to acquire words for both individual objects and object categories, and (...) conceptual biases to construe some objects (notably people) as individuals in their own right and most other objects as instances of their category.

This paper defends the view that philosophical propositions are merely relatively true, i.e. true relative to a doxastic perspective defined at least in part by a non-inferential belief-acquiring method. Here is the strategy: first, the primary way that contemporary philosophers defend their views is through the use of rational intuition, and this method delivers non-inferential, basic beliefs which are then systematized and brought into reflective equilibrium. Second, Christian theologians use exactly the same methodology, only replacing intuition with revelation. Third, intuition (...) and revelation yield frequently inconsistent output beliefs. Fourth, there is no defensible reason to prefer the dictates of intuition to those of Christian revelation. Fifth, the resulting dilemma means that there are true philosophical propositions, but we can't know them (scepticism), or there are no philosophical propositions and the naturalists are right (nihilism), or relativism is true. I suggest that relativism is the most palatable of these alternatives. (shrink)

Throughout its history philosophy has been thought to be a member of a community of intellectual disciplines united by their common pursuit of knowledge. It has sometimes been thought to be the queen of the sciences, at other times merely their under-labourer. But irrespective of its social status, it was held to be a participant in the quest for knowledge – a cognitive discipline.

This paper argues that most of the alleged straight solutions to the sceptical paradox which Kripke ascribed to Wittgenstein can be regarded as the first horn of a dilemma whose second horn is the paradox itself. The dilemma is proved to be a by‐product of a foundationalist assumption on the notion of justification, as applied to linguistic behaviour. It is maintained that the assumption is unnecessary and that the dilemma is therefore spurious. To this end, an alternative conception of the (...) justification of linguistic behaviour is outlined, a conception that vindicates some of the insights behind Kripke's Wittgenstein's sceptical solution of the paradox. This alternative conception is defended against two objections (both familiar from McDowell's works): (1) that it would imply that for the linguistic community there is no authority, no standard to meet and, therefore, no possibility of error and (2) that it would lead to a kind of idealism.

Identifying plausible truthmakers for negative truths has been a serious and perennial problem for truthmaker theory. I argue here that negative truths are indeed made true but not in the way that positive truths are. I rely on a distinction between “existence-independence” and “variation-independence” drawn by Hoffman and Horvath to characterize the unique form of dependence negative truths exhibit on reality. The notion of variation-independence is then used to motivate a principle of truthmaking for contingent negative truths.

The current view of theoretical statements in science is that they should be literal and precise; ambiguous and metaphorical statements are useful only as pre-theoretical, exegetical, and heuristic devices and as pedagogical tools. In this paper we argue that this view is mistaken. Literal, precise statements apply to those experiential phenomena which can be defined either conventionally by criterial attribution or by internal atomic constitution. Experiential phenomena which are defined relationally and/or functionally, like nursing, in virtue of their nature, require (...) metaphorical description and explanation. In such cases, metaphor is theory-constitutive. Using insights from the philosophies of language and mind, and examples from nursing practice, education, and our own empirical research, we explore the nature of metaphor and its role in theory constitution. We argue that the apparent resistance of certain experiential phenomena to literal description and explanation is not necessarily indicative of pre-theoretic linguistic imprecision. We suggest, rather, that such resistance provides useful insights into the nature of such experiential phenomena. We also suggest that the aim of scientific theory should be methodological or epistemological precision and not merely linguistic precision. (shrink)

Kripkean examples of necessary a posteriori truths clearly provide a challenge to attempts to connect facts about possibility to facts about what people can conceive. The paper argues for a general principle connecting imaginability under certain special circumstances to possibility; it also discusses some of the issues raised by the resulting position.

SummaryDummett has offered an argument which begins with certain criteria of adequacy for any account of the way in which communication functions and which ends with normative and revisionary conclusions concerning our logical practice. This argument, which hinges on Dummett's criticisms of holism, is inadequate as it stands, for the holist can give an adequate description of the functioning of communication. There is a plausible defence of intuitionism to be extracted from Dummett's writing, but it should be recognised that it (...) has a normative starting point and does not follow from the criteria of adequacy with which Dummett apparently begins.

In this paper, I propose a new way of understanding the space of possibilities in the field of mental content. The resulting map assigns separate locations to theories of content that have generally been lumped together on the more traditional map. Conversely, it clusters together some theories of content that have typically been regarded as occupying opposite poles. I make my points concrete by developing a taxonomy of theories of mental content, but the main points of the paper concern not (...) merely how to classify, but how to understand, the theories. Also, though the paper takes theories of mental content as a case study, much of the discussion is applicable to theories of other phenomena. To a first approximation, the difference between the traditional and the proposed taxonomies turns on whether we classify theories of content by, on the one hand, their implications for a non-redundant supervenience base for content facts (i.e., for facts about what contents thoughts have) or, on the other, by their constitutive accounts of content. By a "constitutive account," I mean the kind of elucidation of the nature of a phenomenon that theorists have tried to give for, for example, knowledge, justice, personal identity, consciousness, convention, heat, and limit. The tendency to taxonomize by supervenience base is encouraged, I suggest, by a failure to keep clearly in view a distinction between constitutive and modal determination. Many philosophers would accept that a constitutive account cannot be captured in purely modal terms. Giving a constitutive account is not the same as specifying modally necessary and sufficient conditions. Nevertheless, philosophers often try to cash constitutive claims in modal terms. A case in point is that theories of content tend to be conceptualized in terms of the theories' implications for a supervenience base for content facts. My thesis goes beyond the by-now somewhat familiar proposition that not all modal determinants of a phenomenon are constitutive determinants. One who has taken that point on board might nevertheless conceive of a philosophical account as an attempt to specify constitutive determinants of the target phenomenon that make up a non-redundant supervenience base for the phenomenon. Shoehorning a philosophical account into this form leaves out elements that are modally redundant, but may be explanatorily or ontologically significant. For example, when a constitutive account has multiple levels, the different levels will typically be modally redundant. Formulating the account as a specification of a supervenience base of constitutive determinants will therefore flatten the account into a single level. Many of my arguments can be illustrated by considering the place of normativity in the theory of content. The new taxonomy gives a distinct niche to normative theories of content - theories that explain a thought's having a certain content at least in part in terms of the obtaining of normative facts. By contrast, on a traditional map, normative theories are invisible as such because normative facts supervene on non-normative ones. (shrink)

The Hooded Man Paradox of Eubulides concerns the apparent failure of the substitutivity of identicals in epistemic (and other intentional) contexts. This paper formulates a number of different versions of the paradox and shows how these may be solved using semantics for quantified epistemic logic. In particular, two semantics are given which invalidate substitution, even when rigid designators are involved.

In lecture III of Naming and Necessity, Kripke extends his claim that names are non-descriptive to natural kind terms, and in so doing includes a brief supporting discussion of terms for natural phenomena, in particular the terms ‘light’ and ‘heat’. Whilst natural kind terms continue to feature centrally in the recent literature, natural phenomenon terms have barely figured. The purpose of the present paper is to show how the apparent similarities between natural kind terms and the natural phenomenon terms on (...) which Kripke focuses are outweighed by more significant differences. Thus, rather than providing additional support for non-descriptivism, natural phenomenon terms turn out to challenge that thesis. (shrink)

Proponents of the predicate view of names explain the reference of an occurrence of a name N by invoking the property of bearing N. They avoid the charge that this view involves a vicious circularity by claiming that bearing N is not itself to be understood in terms of the reference of actual or possible occurrences of N. I argue that this approach is fundamentally mistaken. The phenomenon of ‘reference transfer’ shows that an individual can come to bear a name (...) in virtue of the referential practices of a group of speakers. I develop a picture of name-bearing which captures this fact by treating the extension of name as a function of the way that extension is represented in the presuppositions of groups of speakers. I show that though there is a form of circularity inherent in this approach, it is not vicious circularity. (shrink)

Predicativism about names—the view that names are metalinguistic predicates—has yet to confront a foundational issue: how are names represented in the lexicon? I provide a positive characterization of the structure of the lexicon from the point of view Predicativism. I proceed to raise a problem for Predicativism on the basis of that characterization, focusing on cases in which individuals have names which are spelled the same way but pronounced differently. Finally, I introduce two potential strategies for solving the problem, and (...) offer reasons not to be optimistic about either. (shrink)
