In this paper I discuss an unconventional form of presentism which, I claim, captures better than all other versions of the doctrine the fundamental notion underpinning it, namely, the notion that 'only what is present is real'. My proposal is to take this maxim as stating, not the rather uncontroversial view that past things are not real now, but the more radical idea that they never were. This rendition of presentism is, I argue, the only one that is neither trivial (...) nor absurd. I examine this proposal by considering it against a sceptical hypothesis that bears similarities to it, viz., the hypothesis that the world was created five minutes ago. On this hypothesis, the past, all but five minutes of it, is unreal, in precisely the sense in which the presentism I discuss claims it is. I show that, assuming semantic externalism, this sceptical hypothesis cannot be sustained, but that a somewhat weaker hypothesis, the Creationist hypothesis that the world is 5,768 years old, cannot be refuted. Together, these conclusions enable a demarcation of those presentist intuitions that language and thought tolerate and those they do not. (shrink)

In this paper, I argue that context sensitivity is crucial for a proper exegesis of Wittgenstein's remark that one can say of the standard metre rod neither that it is one metre long nor that it is not one metre long. I discuss cases in which we can meaningfully assert that the rod in question is one metre long and explain why these cases do not conflict with Wittgenstein's insight. I analyse Pollock's recent defence of Wittgenstein's remark, as well as (...) Kripke's objections to it, and show that, while their commentaries are helpful, blindness to context renders them unsatisfactory. (shrink)

I critically assess Stephen Yablo’s claim that cassinis are ovals is an a posteriori conceptual necessity. One does not know it simply by mastering the relevant concepts but by substantial empirical scrutiny. Yablo represents narrow content by would have turned out -conditionals. An epistemic reading of such conditionals does not bear Yablo’s claim. Two metaphysically laden readings are considered. In one reading, Yablo’s conditionals test under what circumstances concepts remain the same while their extensions diverge. As an alternative, I develop (...) a more literal metaphysical interpretation: Yablo’s conditionals draw on scenarios which are qualitatively identical to some original situation. None of these interpretations sustains Yablo’s core thesis. (shrink)

This paper argues that a consideration of the problem of providing truthmakers for negative truths undermines truthmaker theory. Truthmaker theorists are presented with an uncomfortable dilemma. Either they must take up the challenge of providing truthmakers for negative truths, or else they must explain why negative truths are exceptions to the principle that every truth must have a truthmaker. The first horn is unattractive since the prospects of providing truthmakers for negative truths do not look good neither absences, nor totality (...) states of affairs, nor Graham Priest and J.C. Beall’s ‘polarities’ (Beall, 2000; Priest, 2000) are up to the job. The second horn, meanwhile, is problematic because restricting the truthmaker principle to atomic truths, or weakening it to the thesis that truth supervenes on being, undercuts truthmaker theory’s original motivation. The paper ends by arguing that truthmaker theory is, in any case, an under-motivated doctrine because the groundedness of truth can be explained without appeal to the truthmaker principle. This leaves us free to give the ommonsensical and deflationary explanation of negative truths that common-sense suggests. (shrink)

I argue that a pragmatic scepticism about metaphysical modality is a perfectly reasonable position to maintain. I then illustrate the difficulties and limitations associated with some strategies for defeating such scepticism. These strategies appeal to associations between metaphysical modality and the following: objective probability, counterfactuals and distinctive explanatory value.

McFetridge (in Logical necessity and other essays . London: Blackwell, 1990 ) suggests that to treat a proposition as logically necessary—to believe a proposition logically necessary, and to manifest that belief—is a matter of preparedness to deploy that proposition as a premise in reasoning from any supposition. We consider whether a suggestion in that spirit can be generalized to cover all cases of absolute necessity, both logical and non-logical, and we conclude that it can. In Sect. 2, we explain the (...) significance that such an account of manifestation of belief in absolute necessity has for the prospects of a non-realist theory of modality. In Sect. 3, we offer a sympathetic articulation of the detail that underlies the McFetridge conception of belief in logical necessity. In Sects. 4 and 5, we show that the conception so articulated will not generalize to encompass all cases of belief in absolute necessity and proceed to offer a remedy. Our proposal is based upon a distinction between two kinds of suppositional act: A-supposing and C-supposing (Sect. 6). In Sect. 7, we then explain and defend our central thesis: (roughly) that (manifestation of) belief in absolute necessity is a matter of preparedness to deploy as a premise in reasoning under any C-supposition. Finally, we indicate that there is some promise in the parallel thesis that manifestation of the treatment of a proposition as a priori is a matter of preparedness to deploy as a premise in reasoning under any A-supposition (Sect. 8).

In `Essence and Modality', Kit Fine proposes that for a proposition to be metaphysically necessary is for it to be true in virtue of the nature of all objects whatsoever. Call this view Fine's Thesis. This paper is a study of Fine's Thesis in the context of Fine's logic of essence (LE). Fine himself has offered his most elaborate defense of the thesis in the context of LE. His defense rests on the widely shared assumption that metaphysical necessity obeys the (...) laws of the modal logic S5. In order to get S5 for metaphysical necessity, he assumes a controversial principle about the nature of all objects. I will show that the addition of this principle to his original system E5 leads to inconsistency with an independently plausible principle about essence. In response, I develop a theory that avoids this inconsistency while allowing us to maintain S5 for meta- physical necessity. However, I conclude that our investigation of Fine's Thesis in the context of LE motivates the revisionary conclusion that metaphysical necessity obeys the principles of the modal logic S4, but not those of S5. I argue that this constitutes a distinctively essentialist challenge to the received view that the logic of metaphysical necessity is S5. (shrink)

We outline a theory of the cognitive role of belief in absolute necessity that is normative and intended to be metaphysically neutral. We take this theory to be unique in scope since it addresses simultaneously the questions of how such belief is (properly) acquired and of how it is (properly) manifest. The acquisition and manifestation conditions for belief in absolute necessity are given univocally, in terms of complex higher-order attitudes involving two distinct kinds of supposition (A-supposing and C-supposing). It is (...) subsequently argued that the proposed acquisition and manifestation conditions are rationally interdependent, and that such harmony affords explanations of connections between different facets of belief in necessity that otherwise remain mysterious.

Here is one argument against realism. (1) Realists are committed to the classical rules for negation. But (2) legitimate rules of inference must conserve evidence. And (3) the classical rules for negation do not conserve evidence. So (4) realism is wrong. Most realists reject 2. But it has recently been argued that if we allow denied sentences as premisses and conclusions in inferences we will be able to reject 3. And this new argument against 3 generates a new response to (...) the antirealist argument: keep 1 and 2, avoiding 4 by rejecting 3. My aim in this paper is to see how much work in the fight against anti-realism this new response can really do. I argue that there is a powerful objection to the response: 2 is in tension with the claim that denied sentences can be premisses and conclusions in inferences. But I show that, even given this objection, the new response has an important role to play. (shrink)

This paper develops a new account of reference-fixing for proper names. The account is built around an intuitive claim about reference fixing: the claim that I am a participant in a practice of using α to refer to o only if my uses of α are constrained by the representationally relevant ways it is possible for o to behave. §I raises examples that suggest that a right account of how proper names refer should incorporate this claim. §II provides such an (...) account.

Kripke defines a rigid designator as one that designates the same object in every possible world in which that object exists. He argues that proper names are rigid. So also, he claims, are various natural kind terms. But we wonder how they could be. These terms are general and it is not obvious that they designate at all. It has been proposed that these kind terms rigidly designate abstract objects. This proposal has been criticized because all terms then seem to (...) come out rigid, thus trivializing rigidity. The paper starts with further criticisms of this proposal aimed particularly at a recent version given by LaPorte. The paper goes on to develop and defend an alternative proposal presented briefly in Devitt and Sterelny (1999): instead of taking those natural kind terms to rigidly designate an object we take them to rigidly apply to the members of their extensions. Schwartz has rightly insisted that a notion of rigidity must do some theoretical work if it is to be interesting. The paper argues that rigid application for kind terms does the same primary work as rigid designation for singular terms, the work of refuting description theories of some terms; and it does the same secondary work, of explaining certain modal phenomena (with one exception).

The article defends the doctrine that Linnaean taxa, including species, have essences that are, at least partly, underlying intrinsic, mostly genetic, properties. The consensus among philosophers of biology is that such essentialism is deeply wrong, indeed incompatible with Darwinism. I argue that biological generalizations about the morphology, physiology, and behavior of species require structural explanations that must advert to these essential properties. The objection that, according to current “species concepts,” species are relational is rejected. These concepts are primarily concerned with (...) what it is for a kind to be a species and throw little light on the essentialist issue of what it is for an organism to be a member of a particular kind. Finally, the article argues that this essentialism can accommodate features of Darwinism associated with variation and change. (shrink)

In their delightfully provocative paper, “Semantics, Cross-Cultural Style,” Edouard Machery, Ron Mallon, Shaun Nichols, and Stephen Stich (2004),[1] make several striking claims about theories of reference. First, they claim: (I) Philosophical views about reference “are assessed by consulting one’s intuitions about the reference of terms in hypothetical situations” (p. B1). This claim is prompted by their observations of the role of intuitions in Saul Kripke’s refutation of the descriptivist view of proper names in favor of a causal-historical view (1980). The (...) particular intuitions they attend to are those aired in discussing Kripke’s cases of Gödel and Jonah. This prompts the next claim: (II) Those particular cases are “central” to Kripke’s refutation (p. B1). Indeed, Machery et al describe these cases as “some of the most influential thought experiments in the philosophy of reference” (p. B8). Inspired by recent work in psychology (e.g., Nisbett et al 2001) that shows “systematic cognitive differences between East Asians and Westerners” (p. B1), Machery et al predicted that there would be cultural differences in referential intuitions. They conducted some ingenious experiments on Gödel and Jonah cases to test this predication. The results in the Gödel cases, although not in the Jonah cases, confirmed their prediction, leading them to conclude: “Westerners are more likely than East Asians to report intuitions that are consistent with the causal-historical view” (p. B1). And, implicitly, they claim: (III) These results raise serious doubts about Kripke’s refutation, which relies solely on the intuitions of Westerners. They are explicit about the following bolder claim: (IV) The fact of these cultural differences “raises questions about the nature of the philosophical enterprise of developing a theory of reference” (p. B1); it points to “significant philosophical conclusions” (p.. (shrink)

Radical Millianism agrees with less radical varieties in claiming that ordinary proper names lack “descriptive senses” and that the semantic content of such a name is just its referent but differs from less radical varieties of Millianism in claiming that any pair of sentences differing only in the exchange of coreferential names cannot differ in truth‐value. This is what makes Radical Millianism radical. The view is surprisingly popular these days, and it is popular despite the fact that, until very recently, (...) there was not a single argument for it. Theodore Sider and David Braun (2006) have tried to provide the missing argument, but, I argue, their attempt fails. I conclude that we (still) have no reason to be Radical Millians. (shrink)

This paper develops a model theoretic semantics for so called “natural kind terms” that reflects the viewpoint of (Kripke, 1980) and (Putnam, 1975). The semantics generates a formal counterpart of the “K-mechanism” investigated in (Salmon, 1981) and in unpublished work by Keith Donnellan.

Practitioners of the new ‘experimental philosophy’ have collected data that appear to show that some philosophical intuitions are culturally variable. Many experimental philosophers take this to pose a problem for a more traditional, ‘armchair’ style of philosophizing. It is argued that this is a mistake that derives from a false assumption about the character of philosophical methods; neither philosophy nor its methods have anything to fear from cultural variability in philosophical intuitions.

It is argued on a variety of grounds that recent results in 'experimental philosophy of language', which appear to show that there are significant cross-cultural differences in intuitions about the reference of proper names, do not pose a threat to a more traditional mode of philosophizing about reference. Some of these same grounds justify a complaint about experimental philosophy as a whole.

In this short discussion note, I discuss whether any of the generalizations made in biology should be construed as laws. Specifically, I examine a strategy offered by Elliot Sober ( 1997 ) and supported by Mehmet Elgin ( 2006 ) to reformulate certain biological generalizations so as to eliminate their contingency, thereby allowing them to count as laws. I argue that this strategy entails a conception of laws that is unacceptable on two counts: (1) Sober and Elgin’s approach allows the (...) possibility of formulating laws describing any biological phenomenon whatsoever; and (2) on Sober and Elgin’s view, any interesting contrast between so-called laws and obviously accidental generalizations collapses. I conclude by offering suggestions to refine their view in order to avoid these theoretical problems. (shrink)

A standard view of reference holds that a speaker's use of a name refers to a certain thing in virtue of the speaker's associating a condition with that use that singles the referent out. This view has been criticized by Saul Kripke as empirically inadequate. Recently, however, it has been argued that a version of the standard view, a /response-based theory of reference/, survives the charge of empirical inadequacy by allowing that associated conditions may be largely or even entirely implicit. (...) This paper argues that response-based theories of reference are prey to a variant of the empirical inadequacy objection, because they are ill-suited to accommodate the successful use of proper names by pre-school children. Further, I argue that there is reason to believe that normal adults are, by and large, no different from children with respect to how the referents of their names are determined. I conclude that speakers typically refer /positionally/: the referent of a use of a proper name is typically determined by aspects of the speaker's position, rather than by associated conditions present, however implicitly, in her psychology.

Among the most remarkable developments in metaphysics since the 1950’s is the explosion of philosophical interest in possible worlds. This paper proposes an explanation of what possible worlds are, and argues that this proposal, the interpreted models conception, should be attractive to anyone who thinks that modal facts are primitive, and so not to be explained in terms of some non-modal notion of “possible world.” I articulate three constraints on any acceptable primitivist explanation of the nature of possible worlds, and (...) show that the interpreted models conception meets the three constraints.

It is difficult to wander far in contemporary metaphysics without bumping into talk of possible worlds. And, reference to possible worlds is not confined to metaphysics. It can be found in contemporary epistemology and ethics, and has even made its way into linguistics and decision theory. What are those possible worlds, the entities to which theorists in these disciplines all appeal? Some have hoped that a theory of possible worlds can be used to reduce modality to non-modal terms. This paper (...) sets reductive theories aside, and articulates and applies a framework for evaluating non-reductive theories of possible worlds. I argue that, if we abjure reduction, we should aim for a theory of possible worlds that is user-friendly. I then outline four leading contemporary theories and consider objections to each. My conclusions are negative: every theory we discuss fails to be user-friendly in some significant respect. (shrink)

It is difficult to wander far in contemporary metaphysics without bumping into talk of possible worlds. And reference to possible worlds is not confined to metaphysics. It can be found in contemporary epistemology and ethics, and has even made its way into linguistics and decision theory. What are those possible worlds, the entities to which theorists in these disciplines all appeal? This paper sets out and evaluates a leading contemporary theory of possible worlds, David Lewis's Modal Realism. I note two (...) competing ambitions for a theory of possible worlds: that it be reductive and user-friendly. I then outline Modal Realism and consider objections to the effect that it cannot satisfy these ambitions. I conclude that there is some reason to believe that Modal Realism is not reductive and overwhelming reason to believe that it is not user-friendly. (shrink)

Alison Simmons, in Simmons (1999), argues that Descartes in Meditation Six offered a teleological account of sensory representation. According to Simmons, Descartes’ view is that the biological function of sensations explains both why sensations represent what they do (i.e., their referential content) and why they represent their objects the way they do (i.e., their presentational content). Moreover, Simmons claims that her account has several advantages over other currently available interpretations of Cartesian sensations. In this paper, I argue that Simmons’ teleological (...) account cannot be sustained for both theoretical and textual reasons and that it does not have the advantages it is claimed to have. (shrink)

At least three different issues are commonly referred to by the term “the species problem”: one concerns the necessary properties of species, a second the processes responsible for the existence of species, and a third methods for inferring species limits. Solutions have recently been proposed to the first two problems, which are conceptual in nature (the third is methodological). The first equates species with metapopulation lineages and proposes that existence as a separately evolving metapopulation lineage be considered the only necessary (...) property of species. The second views the species category as a cluster concept and proposes that no single process or set of processes be considered necessary for the existence of species. Although these two solutions have been portrayed as being in conflict, they are, in fact, highly compatible. Moreover, the proposals in question clarify the problem concerning methods for inferring the limits of species, which has for a long time been confused with the problem concerning the necessary properties of species. Together these proposals provide the opportunity for biology to move beyond debates about the definition of the species category and focus on estimating the boundaries and numbers of species as well as studying the diverse processes involved in their origin and persistence.

An intuitive objection to modal realism is that merely possible worlds and their inhabitants seem to be irrelevant to an analysis of modality. Kripke originally phrased the objection in terms of being concerned about one’s modal properties without being concerned about the properties one’s other-worldly counterparts have. The author assesses this objection in a variety of forms, and then provides his own formulation that does not beg the question against the modal realist. Finally, the author considers two potential answers to (...) the objection so understood and concludes that only one of them has a chance of succeeding. (shrink)

I defend and revise the systematic account of normative functions (teleofunctions), as recently developed by Gerhard Schlosser and by W. D. Christensen and M. H. Bickhard. This account proposes that teleofunctions are had by structures that play certain kinds of roles in complex systems. This theory is an alternative to the historical etiological account of teleofunctions, developed by Ruth Millikan and others. The historical etiological account is susceptible to a general ontological problem that has been under-appreciated, and that offers important (...) reasons to adopt the systematic account. However, the systematic account must be revised to allow for two distinct kinds of teleofunctions in order to avoid another ontological problem. (shrink)

The superfunctionality claim is that phenomenal experiences are more than functional (objective, causal) relations. This is one of the most widely used but least attacked claims in the anti-physicalist literature on consciousness. Coupled with one form of structuralism, the view that science only explains functional relations, the superfunctionality claim entails that science will not explain phenomenal experience. The claim is therefore essential to many anti-physicalist arguments. I identify an open question argument for the superfunctionality claim that expresses an intuition deserving (...) of explanation. Using the experience of fear as an example, I show that this intuition cannot distinguish between whether conscious experiences are more than functional relations, or whether instead they are just very complex (including, constituted by very complex functional relations). I give reasons to suspect that the latter is more likely the case. This renders physicalism safe from the superfunctionality claim. This also provides a challenge to the proponents of the superfunctionality claim: they should explain why paradigmatically mysterious phenomenal experiences are correlated with extensive and complex physical correlates.

It has seemed natural to model phenomena related to vagueness in terms of graded membership. However, so far no satisfactory answer has been given to the question of what graded membership is nor has any attempt been made to describe in detail a procedure for determining degrees of membership. We seek to remedy these lacunae by building on recent work on typicality and graded membership in cognitive science and combining some of the results obtained there with a version of the (...) conceptual spaces framework.

According to Locke’s Principle, material objects are identical if and only if they are of the same kind and once occupy the same place at the same time. There is disagreement about whether this principle is true, but what is seldom disputed is that, even if true, the principle fails to constitute an applicable criterion of identity. In this paper, I take issue with two arguments that have been offered in support of this claim by arguing (i) that we can (...) have knowledge of past whereabouts, and so verify the right hand side of Locke’s Principle, without having to assess concrete identity claims first; (ii) that even under conditions of incomplete knowledge of past whereabouts we can use Locke’s Principle to decide concrete identity problems.

George Wilson has defended the thesis that even impersonal third-person fictional narratives should be taken to contain fictional narrations and have fictional narrators. This, he argues, is necessary if we are to explain how readers can take themselves, in their imaginative engagement with fictions, to have knowledge of the things they are imagining. I argue that there is at least one class of impersonal third-person fictional narratives—thought experiments—to which Wilson’s model fails to apply, and that this reveals more general problems (...) with his argument. I further argue that there is no good reason to think that Wilson’s account applies more restrictedly to those impersonal third-person fictional narratives that feature in standard works of literary fiction.

Religious exclusivism, or the idea that only one religion can be true, fuels hatred and conflict in the modern world. Certain objections to religious pluralism, together with associated defences of exclusivism are flawed. I defend a moderate religious pluralism, according to which the truth of one religion does not automatically imply the falsity of others. The thought that we can respect persons even when holding them mistaken strains credulity when we are dealing with religious convictions. Moreover, exclusivism is informed by (...) inadequate approaches to discourse about transcendence. The intentional-descriptivist approach to reference is not comprehensively adequate, and yet is assumed by some objections to pluralism. The irreducibly metaphorical character of much religious language means that differences between world religions can be more apparent than real. Approaches to religious education should embrace a moderate religious pluralism. (shrink)

Berg seeks to defend the theory that the meaning of a proper name in a belief report is its reference against Frege’s puzzle by hypothesizing that when substituting coreferential names in belief reports results in reports that seem to have different truth values, the appearance is due to the fact that the reports have different metalinguistic implicatures. I review evidence that implicatures cannot be calculated in the way Grice or Berg imagine, and give reasons to believe that belief reports do (...) not have the implicatures Berg attributes to them. I also argue that even if belief reports did have such implicatures, they would not explain why the belief reports in Frege’s puzzle seem to have different truth values. I point out that Berg has no reason to believe that Lois Lane believes Clark Kent is a reporter and Lois Lane believes Superman is a reporter are both true rather than both false, and that Leibniz’s Law cannot be used to defend substitutivity in belief reports because belief reports are not relational in the requisite way. Finally, I observe that some of the linguistic data Berg uses to argue for substitutivity in belief reports concerns the transparent interpretation of belief reports, whereas Frege’s puzzle concerns the opaque interpretation.

The causal and simulation theories are often presented as very distinct views about declarative memory, their major difference lying on the causal condition. The causal theory states that remembering involves an accurate representation causally connected to an earlier experience. In the simulation theory, remembering involves an accurate representation generated by a reliable memory process. I investigate how to construe detailed versions of these theories that correctly classify memory errors as misremembering or confabulation. Neither causalists nor simulationists have paid attention to (...) memory-conjunction errors, which is unfortunate because both theories have problems with these cases. The source of the difficulty is the background assumption that an act of remembering has one target. I fix these theories for those cases. The resulting versions are closely related when implemented using tools of information theory, differing only on how memory transmits information about the past. The implementation provides us with insights about the distinction between confabulatory and non-confabulatory memory, where memory-conjunction errors have a privileged position. (shrink)

This paper develops the first parts of a logical framework for the empirical sciences, by means of a redefinition of theory structuralism as originally developed by Joseph Sneed, Wolfgang Stegmüller, and others, in the context of a ‘rigid’ logic as based on a fixed (therefore rigid) ontology. The paper defends a formal conception of the empirical sciences that has an irreducible ontological basis and is unable, in general, to provide purely structural characterizations of the domain of a theory. The extreme (...) rationalist utopia of a characterization of the real world ‘up to isomorphism’, therefore, is rejected. (shrink)

In several publications Graeme Forbes has developed and defended one of the strongest arguments for essentialism about biological origins. I attempt to show that there are deep, as yet unrecognized, problems with this argument. The problems with Forbes’s argument suggest that a range of other arguments for various forms of origin essentialism are also likely to be flawed, and that we should abandon the seemingly plausible general metaphysical thesis that concrete entities that share all intrinsic properties are identical.

Revelation is the thesis that having an experience that instantiates some phenomenal property puts us in a position to know the nature or essence of that property. It is widely held that although Revelation is prima facie plausible, it is inconsistent with physicalism, and, in particular, with the claim that phenomenal properties are physical properties. I outline the standard argument for the incompatibility of Revelation and physicalism and compare it with the Knowledge Argument. By doing so, I hope to show (...) that on various plausible interpretations of Revelation it is in fact consistent with physicalism. Moreover, there is a robust reading of Revelation that a posteriori physicalists can, and should, accept. (shrink)

In the last 30 years repeated attempts have been made to develop a proof-sketch Kripke gave for essentialism about material origins into a cogent argument. I argue that there are general reasons that all such attempts have failed, and so we should likewise expect future attempts to fail.

In 1952, two well-known characters called ‘A’ and ‘B’ met for the first time to argue about the Identity of Indiscernibles (Black, 1952). A argued that the principle is true, and B that it is false. By all accounts A took a bit of a beating and came out worst-off. Forty-three years later John O’Leary-Hawthorne offered a response on behalf of A that looked as if it would work so long as A was willing to accept the universal-bundle theory of (...) substance (Hawthorne, 1995). In 1997, A and B met again (Zimmerman, 1997). A took Hawthorne’s advice and revealed himself as a universal-bundle theorist. But B was well-prepared, and once more A took a beating. Since then Gonzalo Rodriguez-Pereyra (2004) has put the boot in, offering further criticism of A’s position. In recent years A has been rather quiet, leaving B to reign as the undisputed champion. However, it turns out that A is down, but not out. And now it’s time for A’s revenge. (shrink)
