David Lewis advised essentialists to judge his counterpart theory a false friend. He also argued that counterpart theory needs natural properties. This essay argues that natural properties are all essentialists need to find a true friend in counterpart theory. Section one explains why Lewis takes counterpart theory to be anti-essentialist and why he thinks it needs natural properties. Section two establishes the connection between the natural properties counterpart theory needs and (...) the essentialist consequences Lewis disavows. Section three answers two objections: the first attempts to block the consequences of adding natural properties to counterpart theory; the second grants the consequences, but denies that they amount to essentialism. –Correspondence to: [email protected].

David Lewis may be regarded as an antiessentialist. The reason is that he is said to believe that individuals do not have essential properties independent of the ways they are represented. According to him, indeed, the properties that are determined to be essential to individuals are a matter of which similarity relations among individuals are salient, and salience, in turn, is a contextual matter also determined to some extent by the ways individuals are represented. Todd Buras argues (...) that the acknowledgment of natural properties in counterpart theoretic ontology affects Lewis’s theory with regard to essentialism. Buras’s reasoning is appealing. He claims that, since natural properties determine the existence of similarity relations among individuals that are salient independent of context, Lewis can no longer be claimed to be an antiessentialist. The aim of this paper is to argue, against Buras, that if counterpart theory was antiessentialist before natural properties were taken into account, then it remains so afterwards. (shrink)

Counterpart theory affords an especially flexible form of essentialism. Gideon Rosen and the author suggested that by endowing the entire world with peculiar essences, they could likewise provide truth makers for negative existential propositions. Thus they avoid the need for states of affairs or non‐transferable tropes as truth makers. States of affairs are somehow constructed from particular things and the properties they instantiate. A legitimate counterpart relation can exist which validates only one direction of set‐theoretical essentialism, but under (...) which any counterpart of a state of affairs must be a state of affairs. States of affairs or tropes are not needed for purposes of truth making. But also, if we help ourselves to the flexibility of counterpart theory, the principal difficulties that stand in the way of using states of affairs or tropes as truth makers vanish. (shrink)

I call anti-resemblism the thesis that independently of any contextual specification there is no determinate fact of the matter about the comparative overall similarity of things. Anti-resemblism plays crucial roles in the philosophy of David Lewis. For instance, Lewis has argued that his counterpart theory is anti-essentialist on the grounds that counterpart relations are relations of comparative overall similarity and that anti-resemblism is true. After Lewis committed himself to a form of realism about natural properties he (...) maintained that anti-resemblism is true about the relations of overall similarity that enter his counterpart theory and his analysis of counterfactuals. However, in this article I argue that Lewis’s account of degrees of naturalness for properties combined with his modal realism entails that anti-resemblism is false. The Lewisian must amend Lewis’s system if she aims to benefit from the alleged virtues of anti-resemblism. I consider two ways of amending it, neither of which is a free lunch. (shrink)

JOHN RAWLS IN A Theory of Justice attempts to deduce "the principles of justice" from the idea of a "contract" among free and equal persons. The factor which obviously distinguishes Rawls’ contract doctrine from the teachings of the great social contract philosophers who preceded him is that it does not rest on any examination of what the character of an actual nonpolitical condition or "state of nature" among men would be. Rawls’ procedure is in fact the opposite of that followed (...) by his predecessors: instead of inferring the principles of the contract from what men, given their nature, would be likely to agree upon in the absence of an already existing government and set of laws, he freely constructs the character and circumstances of the parties to his "purely hypothetical" "original position of equality" in order "to lead to a certain conception of justice". That conception is to consist of. (shrink)

This paper critically assesses the “procedural” accounts of political justice set forth by John Rawls in A Theory of Justice (1971) and Robert Nozick in Anarchy, State, and Utopia (1974). I argue that the areas of agreement between Rawls and Nozick are more significant than their disagreements. Even though Nozick offers trenchant criticisms of Rawls's argument for economic redistribution (the “difference principle”), Nozick's own economic libertarianism is undermined by his “principle of rectification,” which he offers as a possible ground in (...) practice for the application of something like the difference principle. Both Rawls's and Nozick's accounts of justice fail because of their abstraction from human nature as a ground of right. At the same time the libertarianism on which they agree in the non-economic sphere would deprive a free society of its necessary moral underpinning. Rawls and Nozick err, finally, by demanding that the policies pursued by a just society conform to theoretical formulas concocted by philosophy professors, rather than leaving room (as Lockean liberalism does) for the adjustment of policies to particular circumstances based on statesmen's prudential judgment and the consent of the governed. Particularly troubling from the perspective of a citizen seriously concerned with the advancement of justice and freedom is both thinkers' shrill denunciations of existing liberal societies for failing to conform to their particular strictures.

It is common in the history of science to try to extend an idea first demonstrated in one domain into others. Sometimes the extension is literal, and sometimes it is frankly metaphorical. Sometimes, however, when an extension is claimed to be literal, it is far from easy to see that it is. If an extension does not make use of entities and mechanisms involved in the original domain, and introduces novel entities and mechanisms, then it is not unreasonable to doubt (...) the claim of its authors that it is a literal extension of a well-established theory. IT is, therefore, not surprising that many who accept that the cultural transmission of information is unique to out species nevertheless balk at Dawkins's and Dennett's contention that there are units of cultural evolution, called 'memes', which can be used to explain the development and diversity of human culture, and whose survival is explicable in terms of Darwin's theory of evolution by natural selection. Our aim in this paper is to argue that scepticism about Dawkins's and Dennett's proposal is indeed justified; though it of course does not follow that there is not another way of explaining human culture in evolutionary terms.

We extend in a natural way the operation of Turing machines to infinite ordinal time, and investigate the resulting supertask theory of computability and decidability on the reals. Everyset. for example, is decidable by such machines, and the semi-decidable sets form a portion of thesets. Our oracle concept leads to a notion of relative computability for sets of reals and a rich degree structure, stratified by two natural jump operators.

Several alleged counterexamples to the definition of ‘intrinsic’ proposed in Rae Langton and David Lewis, ‘Defining “Intrinsic”’, are unconvincing. Yet there are reasons for dissatisfaction, and room for improvement. One desirable change is to raise the standard of non-disjunctiveness, thereby putting less burden on contentious judgements of comparative naturalness. A second is to deal with spurious independence by throwing out just the disjunctive troublemakers, instead of throwing out disjunctive properties wholesale, and afterward reinstating those impeccably intrinsic disjunctive properties that (...) are not troublemakers. (The second of these changes makes the first more affordable.) A third, suggested by Brian Weatherson, would be to invoke the general principle that the intrinsic and the extrinsic characters of things are independent, rather than relying just on one special case of this principle; but it is none too obvious how to do this.

Many theories assimilate the idioms of modality to those of quantification; they hold that so-and-so is possible iff there is a "world" at which it is true that so-and-so. "Modal realism" identifies worlds with certain concrete particulars, and truth at a world with what is true of it. Rival "ersatz" theories identify worlds with certain abstract entities and identify what is true at them with what they represent. ;David Lewis argues that pre-theoretic modal intuitions are best explained by modal (...) realism. I try to make a case for ersatzism. ;First, I argue that modal realism is flawed on the grounds that it entails the impossibility of certain intuitively possible spatiotemporal structures; it fails to explain fully even those intuitions with which it is compatible; and it renders the origin of modal knowledge mysterious. ;Next, I argue that objections to ersatzism are not conclusive. ;Lewis objects that even a generic version of ersatzism requires an unnameable and maybe unintelligible primitive relation. I suggest that the problems with naming are perfectly general; they have nothing to do with metaphysical theories of modality in particular. And I suggest a solution taken from Lewis himself. I also argue that any purported unintelligibility is due to illegitimately assimilating the relation to spatiotemporal relations. ;Finally, I consider some difficulties with a version of ersatzism that aims to reduce modality to impure set-theory. One concerns the accommodation of intuitions about properties that are not, but might have been, instantiated. Another concerns accommodation of intuitions about relations of exclusion and entailment among properties. I suggest that these difficulties are due to faulty assumptions about the nature of properties rather than any fundamental flaws in this ersatz approach. So I propose an account of properties that when incorporated into ersatzism circumvents these difficulties and allows it to claim the advantages of modal realism without its drawbacks. Unlike traditional accounts, this takes the essence of a property to consist in its role in imposing a certain classificational structure on the particulars that instantiate it, rather than in any unique and irreducible "quiddity".

For many years essentialism was considered beyond the pale in philosophy, a relic of discredited Aristotelianism. This is no longer so. Kripke and Putnam have made belief in essential natures respectable once more. Harré and Madden have argued against Hume's theory of causation and developed an alternative theory based on the assumption that there are genuine causal powers in nature. Dretske, Tooley, Armstrong, Swoyer, and Carroll have all developed strong alternatives to Hume's theory of the laws of nature. And Shoemaker (...) has developed a thoroughly non-Humean theory of properties. The "new essentialism" has evolved from these beginnings and can now reasonably claim to be a metaphysic for a modern scientific understanding of the world - one that challenges the conception of the world as comprising passive entities whose interactions are to be explained by appeal to contingent laws of nature externally imposed.

David Lewis is usually thought to reject what Quine called “Aristotelian essentialism”. The starting point of this paper is to define and explain Aristotelian essentialism and locate it in the context of the criticism that Quine made of quantified modal logic. Indeed, according to Quine, Aristotelian essentialism would be one of the consequences of accepting quantified modal logic. After having explained Lewis’s stance in the Quinean debate against quantified modal logic, this paper will deal with the question as to (...) whether Lewis accepts or rejects Aristotelian essentialism. I think there are different plausible interpretations of the essentialist thesis, and I will distinguish between three such interpretations. This distinction between different interpretations of essentialism is both interesting per se and helpful in understanding the senses in which Lewis is or is not an antiessentialist. I will say, in fact, that while it is true that Lewis rejects Aristotelian essentialism under the first two understandings of the essentialist thesis, he endorses such a thesis according to a third understanding. I will then take this to show that there is a sense in which Aristotelian essentialism survives in Lewis’s metaphysical theory. (shrink)

For Reid perception, broadly speaking, was a complex of two very different mental states. Calling such views dual component theory, A. D. Smith questions whether any such theory, and whether Reid's version in particular, is a viable theory of perception. The aim of this paper is to defend Reidian Dual Component Theory from Smith's critique. Answering Smith's critique reveals the depth and resilience of Reid's approach to perception, highlighting specifically the continued interest of his thought about the relationship between sensation (...) and perception, the nature of illusion, the immediacy of perception, and the content of perceptual belief.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aquinas’s Theory of Natural Law: An Analytic Reconstruction by Anthony J. LisskaV. Bradley LewisAnthony J. Lisska. Aquinas’s Theory of Natural Law: An Analytic Reconstruction. Oxford: Clarendon Press, 1996. Pp. xv + 320. Paper, $24.95.This volume aims to provide an explication of the natural law theory of St. Thomas Aquinas “consistent with the expectation of philosophers in the analytic tradition” (10–11, 17). Accordingly, the author begins, (...) in the first three chapters, by reviewing the recent history of Anglo-American metaethics, aligning himself broadly with those critics of analytic ethics like G. E. M. Anscombe, Alasdair MacIntyre, John Finnis, Martha Nussbaum, and Henry Veatch, who have argued for a recovery of Aristotelian moral theory, against varieties of intuitionism, non-cognitivism, and neo-Kantianism. Lisska’s principal objective is to present a reconstructed natural law theory based primarily on Aquinas’s discussion in questions 90–97 of the prima secundae of the Summa theologiae (a translation of these questions is appended to the book). This he offers mostly in the fourth, fifth and eighth chapters of the book. The sixth chapter is a critique of John Finnis’s account of natural law and the seventh is an exposition of the views of Henry [End Page 526] Veatch. The ninth chapter presents some suggestions on how the author’s account can illuminate controversies over the grounding of human rights, and the tenth is a brief conclusion.The three introductory chapters consist mainly of a review and endorsement of the critics of academic ethics since Moore’s Prıncipia Ethıca. Having accepted arguments for the inadequacy of modern ethics, Lisska argues for the recovery of Aquinas’s views which he sees as in fundamental continuity with Aristotelian ethics (84, 89, 100, 102–105, 108, 134–36). His central thesis is that natural law is a “second-order inquiry” based on a realist metaphysics of the human person as defined by a set of dispositional properties, the realization of which constitutes Aristotelian eudaimonia and Thomistic beatitudo (17, 104–106, 131–37, 152–55, 186, 195–201). Moreover, Lisska contends that Aristotelian “eudaimonism” constitutes an adequate account of moral obligation: what he calls, after Veatch, “obligatory teleology” (107–109, 121, 202–205, 235).At the core of Lisska’s account, then, is a metaphysical dispute that pits Aristotelian essentialism against modern reductionist ontology. This metaphysical core is separated from any theological implications in the fifth chapter (especially 119–23, 137) and Lisska reinforces his metaphysical thesis by appealing to Saul Kripke’s discussion of natural kinds and the early work of Hilary Putnam (97–99, 125, 206–209). Given the centrality of metaphysical argument, a critique of Finnis’s theory goes without saying, and Lisska devotes a chapter to it, adding another to expound Henry Veatch’s contrary view.While this book undertakes an important effort to recover a workable natural law theory—especially in its commendable stress on metaphysical questions—it is, as a whole, less satisfactory than it might have been. A good part of this owes to the book’s abstraction from historical questions. No sustained attention is devoted to the problems that accompanied the reception of Aristotle by Christian theologians, nor to the place of natural law in Aquinas’s overall understanding of morality. The former point is not so surprising, given the book’s analytic concerns; the latter, however, carries more serious theoretical implications. Why is it, for example, that natural law takes up so little space compared to the questions on happiness, human acts, and the habits and virtues in the prima secundae, not to mention the detailed treatments of the virtues and vices in the secunda secundae? Similarly, where Aquinas stresses that natural law as law is directed to the common good (Iallae 90.2), Lisska treats it mostly as a guide to “self-realization.”This issue suggests the tensions between Aristotle and Aquinas, tensions that seem to show themselves precisely in Aquinas’s discussion of the very notion of natural law, a notion that has no equivalent in Aristotle. This question hangs over Lisska’s brief treatment of obligation, in particular, since that concept is also lacking explicit treatment in... (shrink)

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

According to Peter van Inwagen, C. S. Lewis failed in his attempt to undermine naturalism with his Argument from Reason. According to van Inwagen, Lewis provides no justification for his central premise, that naturalism is inconsistent with holding beliefs for reasons. What is worse, van Inwagen argues that the main premise in Lewis's argument from reason is false. We argue that it is not false. The defender of Lewis's argument can make use of the problem of mental causal drainage, a (...) longstanding issue in philosophy of mind, to show how van Inwagen's objection fails. (shrink)

The Moral Twin Earth challenge to ethical naturalism threatens to undermine an otherwise promising metaethical view by showing that typical, naturalist-friendly theories of reference determination predict diverging reference in Twin Earth scenarios, making it difficult to account for substantive moral disagreement. Several theorists have recently invoked David Lewis’s doctrine of reference magnetism as a solution, claiming that a highly elite moral property—a moral “joint in nature”—could secure shared reference between ourselves and our twins on Twin Earth, despite our diverging (...) usages of moral terms. This paper argues that this move has significant methodological implications: namely, it entails that a certain sort of simplicity is truth-conducive. Consequently, when applied to moral theories, this gives certain views, specifically monist ones like utilitarianism and contractualism, an advantage over their more complicated rivals, forms of pluralism and particularism. Thus, ethical naturalists cannot invoke reference magnetism without a substantial impact on first-order theorizing. (shrink)

David Lewis's modal realism claims that nothing can exist in more than one world or time, and that statements about how something would have been are to be analysed in terms of its counterpart. I first explain why the counterpart relation depends on de re modal statements in an intensional language, so that intuitive properties of similarity relations cannot be used to show that the counterpart relation is not an equivalence relation. I then look at test (...) sentences in (the intensional) natural language, and show that none of them provide compelling evidence that a counterpart semantics is needed. (shrink)

According to the eligibility theory of meaning, often attributed to David Lewis, the referent of a predicate is the property that best balances the twin constraints of charity and eligibility, where eligibility is a function of metaphysical naturalness. This sort of metasemantics, which is motivated by its ability to resolve problems of indeterminacy and secure shared reference between disputing parties, can be somewhat friendly towards revisionary theories, since highly natural properties can act as “reference magnets,” securing our reference (...) despite some mismatch with usage. In this paper, I apply these considerations to normative ethics and argue that the theory of rule utilitarianism achieves a high balance of charity and eligibility. I proceed by comparing rule utilitarianism to two of its well-known rivals, act utilitarianism and Rossian pluralism. I show how the former achieves a high degree of eligibility but only at a significant cost of charity, while the latter does the opposite, fitting very nicely with our considered judgments but at the price of very low eligibility. Rule utilitarianism, on the other hand, strikes a good balance between these extremes; it assigns to our core moral term a relatively natural property without doing too much damage to our moral convictions. Thus, rule utilitarianism should be regarded as a promising moral theory by any philosopher who takes seriously considerations of eligibility and naturalness. (shrink)

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.

Tn this paper I explore and to an extent defend HS. The main philosophical challenges to HS come from philosophical views that say that nomic concepts-laws, chance, and causation-denote features of the world that fail to supervene on non-nomic features. Lewis rejects these views and has labored mightily to construct HS accounts of nomic concepts. His account of laws is fundamental to his program, since his accounts of the other nomic notions rely on it. Recently, a number of philosophers have (...) criticized Lewis's account, and Humean accounts of laws generally, for delivering, at best, a pale imitation ofthe genuine item. These philosophers think that the notion of law needed by science requires laws-if there are any-to be fundamental features of our world that are completely distinct from and not supervenient on the particular facts that they explain. I side with Lewis against these philosophers. Here I will argue that although Lewis-laws don't fulfill all our philosophical expectations, they do play the roles that science needs laws to play. The metaphysics and epistemology of Humean laws, and more specifically, Lewis-laws, are in much better shape than the metaphysics and epistemology of the main anti-Humean alternatives. However, I do have inisgivings about Lewis's account. Both he and his critics assume that the basic properties are so individuated so that the laws are not metaphysically necessary. If this assumption is rejected, then the question of Humean supervenience lapses. I conclude with a brief discussion of this position. (shrink)

Many years ago, C.B. Martin drew our attention to the possibility of ‘finkish’ dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s, it is not so that if x were subjected to stimulus r, x would give response z; so finkish dispositions afford a counter‐example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required (...) a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds. (shrink)

Dan Marshall and Josh Parsons note, correctly. that the property of being either a cube or accompanied by a cube is incorrectly classified as intrinsic under the definition we have given unless it turns out to be disjunctive.

They doubt the judgements of relative naturalness that would classify their property as disjunctive. We disagree. They also suggest that the whole idea of (...) judging relative naturalness is a dubious business. We reply that, like them or not, such judgements cannot easily be avoided. (shrink)

Court D. Lewis, author of Repentance and the Right to Forgiveness, presents a rights-based theory of ethics grounded in eirenéism, a needs-based theory of rights (inspired by Nicholas Wolterstorff) that seeks peaceful flourishing for all moral agents. This approach creates a moral relationship between victims and wrongdoers such that wrongdoers owe victims compensatory obligations. However, one further result is that wrongdoers may be owed forgiveness by victims. This leads to the “repugnant implication” that victims may be wrongdoers who do not (...) forgive. Author Lewis addresses the “repugnant implication” by showing that victims are obligated to work toward forgiveness, if not forgiveness itself. Critic Gregory L. Bock argues that victims are not the only ones who can forgive, that the personal dimensions of forgiveness are overlooked, and that the force of the “repugnancy implication” may be questioned. Instead of rights-based eirenéism, Bock supports a virtue ethics framework. Instead of rights-based eirenéism, Bock encourages virtue ethics. Critic David Boersema raises questions about the binding nature of relationships, the dependency of flourishing upon forgiveness, and the nature of needs or rights. Boersema also questions the wisdom of a rights-based approach to forgiveness. Critic Jennifer Kling asks whether a rights-based approach is necessary to ground obligations to meet the needs of others: why not an ethics of care? If a rights-based approach is taken, perhaps a wrongdoer is obligated to not make forgiveness a life good. By disengaging this obligation, we avoid constraining a victim’s work toward forgiveness, especially when the wrongdoing is oppressive. Author Lewis responds to these objections. (shrink)

Actualist counterpart theory replaces David Lewis’s concrete possible worlds and individuals with ersatz worlds and individuals, but retains counterpart theory about de re modality. While intuitively attractive, this view has been rejected for two main reasons: the problem of indiscernibles and the Humphrey objection. I argue that in insisting that ersatz individuals play the same role as Lewisian individuals, actualists commit the particularist fallacy. The actualist should not require stand-ins for every Lewisian individual. Ersatz individuals should instead (...) be construed as representations of actually existing qualitative ways for individuals to be, or qualitative properties individuals can instantiate. This necessitates changes elsewhere. Non-instrumental uses of Kripke semantics and standard counterpart semantics also require stand-ins for particular non-actual individuals. I argue that the actualist should instead adopt a non-standard counterpart semantics that more clearly illuminates the role that actual properties and relations play in explaining de re possibilities and necessities. The result is an intuitive and forceful reply to both the problem of indiscernibles and the Humphrey objection. (shrink)

Consequentialist theories of virtue and vice, such as the theories of Jeremy Bentham and Julia Driver, characterize virtue and vice in terms of the consequential, or instrumental, properties of these character traits. There are two problems with theories of this sort. First they imply that, under the right circumstances, paradigmatic virtues, such as benevolence, are vices and paradigmatic vices, such as maliciousness, are virtues. This is conceptually problematic. Second, they say nothing about the intrinsic nature of the virtues and vices, (...) which is less than we could hope for from a theory of virtue and vice. Thus, we have reason to reject consequentialist theories in favour of theories that characterize virtue and vice in terms of the intrinsic properties of these character traits. Aristotle and Thomas Hurka have theories this sort. (shrink)

Proponents of the causal theory of perception have applied the theory to questions about which particular objects or events are perceived, which parts are perceived, and which properties are perceived.

In order to succeed in this role, perception cannot be grounded in spurious correlations. But we can respect this insight without embracing (...) the idea that a successful percept must be causally dependent on what is perceived. A correlation in nature can also be genuine or lawful when it arises from a common cause. I show how successful perception is frequently achieved through correlation via a common cause. (shrink)

Michel de Montaigne (1533–1592), author of the Essays (published in successive, revised and expanded editions from 1580 until after his death), deserves to be recognized as the first) philosophic architect of modern liberalism, that is, a doctrine that advocates the advancement of individual liberty (under law), and consequently a reduction in the scope and purpose of government to securing what are represented by Montaigne’s successors (Hobbes, Locke, Montesquieu, and the American Founders) as people’s inherent rights to their life, liberty, property, (...) and the “pursuit of happiness” as they conceive it. His outward, periodic professions of extreme conservatism and of homage to the Catholic Church are merely a rhetorical cover designed to protect the author from being persecuted (and his book from being banned). As a practitioner of what he describes as esoteric rhetoric (attributing it to the ancient political philosophers), Montaigne invites careful readers to see through his rhetorical concealment by noting how his conservative professions are undermined by the overall train of his reasoning and argument. Although Montaigne’s argument for liberal individualism may have gone too far in its influence over the long run (that is, the 21st century), we citizens of modern liberal regimes owe him a debt of gratitude for helping to liberate us from the reign of arbitrary monarchs, oppressive aristocrats, and clerical oppressors.

Michael Bergmann seeks to motivate his externalist, proper function theory of epistemic justification by providing three objections to the mentalism and mentalist evidentialism characteristic of nonexternalists such as Richard Feldman and Earl Conee. Bergmann argues that (i) mentalism is committed to the false thesis that justification depends on mental states; (ii) mentalism is committed to the false thesis that the epistemic fittingness of an epistemic input to a belief-forming process must be due to an essential feature of that input, and, (...) relatedly, that mentalist evidentialism is committed to the false thesis that the epistemic fittingness of doxastic response B to evidence E is an essential property of B–E; and (iii) mentalist evidentialism is “unmotivated”. I object to each argument. The argument for (i) begs the question. The argument for (ii) suffers from the fact that mentalist evidentialists are not committed to the consequences claimed for them; nevertheless, I show that there is, in the neighborhood, a substantive dispute concerning the nature of doxastic epistemic fittingness. That dispute involves what I call “Necessary Fittingness”, the view that, necessarily, exactly one (at most) doxastic attitude ( belief , or disbelief , or suspension of judgment ) toward a proposition is epistemically fitting with respect to a person’s total evidence at any time. Reflection on my super-blooper epistemic design counterexamples to Bergmann’s proper function theory reveals both the plausibility of Necessary Fittingness and a good reason to deny (iii). Mentalist evidentialism is thus vindicated against the objections. (shrink)

Dispositional essentialists argue that physical properties have their causal roles essentially. This is typically taken to mean that physical properties are identical to dispositions. I argue that this is untenable, and that we must instead say that properties bestow dispositions. I explore what it is for a property to have such a role essentially. Dispositional essentialists argue for their view by citing certain epistemological and metaphysical implications, and I appeal to these implications to place desiderata on the concept of essence (...) involved. I argue that the traditional modal theory of essence meets these desiderata, but that the resulting theory wrongly implies that certain dispositions essential to mass are essential to charge, thereby offering a new argument against modal theories of essence. I argue that dispositional essentialism requires a primitive notion of essence, and develop a primitivist theory based on Kit Fine's views. I show that the primitivist theory has all the virtues of the modal alternative, and none of the vices. I develop a novel way of thinking about the relationship between properties, laws and dispositions, and argue that it has distinct advantages over standard dispositional essentialist formulations.

Many writers have held that in his later work, David Lewis adopted a theory of predicate meaning such that the meaning of a predicate is the most natural property that is (mostly) consistent with the way the predicate is used. That orthodox interpretation is shared by both supporters and critics of Lewis's theory of meaning, but it has recently been strongly criticised by Wolfgang Schwarz. In this paper, I accept many of Schwarze's criticisms of the orthodox interpretation, and (...) add some more. But I also argue that the orthodox interpretation has a grain of truth in it, and seeing that helps us appreciate the strength of Lewis's late theory of meaning. (shrink)

First published in 1985, D. M. Armstrong's original work on what laws of nature are has continued to be influential in the areas of metaphysics and philosophy of science. Presenting a definitive attack on the sceptical Humean view, that laws are no more than a regularity of coincidence between stances of properties, Armstrong establishes his own theory and defends it concisely and systematically against objections. Presented in a fresh twenty-first-century series livery, and including a specially commissioned preface written by Marc (...) Lange, illuminating its continuing importance and relevance to philosophical enquiry, this influential work is available for a new generation of readers. (shrink)

It is widely held that some properties are more natural than others and that, as David Lewis put it, “an adequate theory of properties is one that recognises an objective difference between natural and unnatural properties” (Lewis 1983, p. 347). The general line of thought is that such ‘elitism’ about properties is justified as it can give simple and elegant solutions to a number of old metaphysical and philosophical problems. My aim is to analyze what these (...) class='Hi'>natural properties are: super-determinates or determinable (or maybe both) and argue that all three of these options would lead to serious difficulties for metaphysical elitism and would prevent natural properties from fulfilling their supposed grand explanatory role.

It is natural to suppose that honey tastes the way it does because it is sweet. Democritus, Plato and Aristotle all agree that this explanation is superficial and lacks causal depth; they attempt to explain gustatory phenomena by invoking explanatorily fundamental features of the world. As they work out their causal stories, do they give up on the common-sense explanation of why honey tastes the way it does? In other words, do they deny that sweetness and other sensible qualities (...) are causally efficacious features of the world around us? ;Our sources for Democritus' thinking on this issue present a problematic picture. On the one hand, Aristotle and Theophrastus suppose that Democritus wants to identify colors and flavors with causally efficacious features of the world around us. On the other hand, Theophrastus and others find Democritus defending the view that colors and flavors do not belong to the world around us. This tension, first pointed out by Theophrastus, is merely apparent, if, as certain texts suggest, Democritus distinguishes the colors and flavors which we experience from the colors and flavors which figure in his scientific explanations. ;In the Timaeus, Plato frequently says things like "What is capable of producing such and such effects on the gustatory region has the name 'bitter' thinspace". On Theophrastus' interpretation, Plato is offering definitions of the sensible qualities: flavors are identical with powers to produce certain physiological effects on the sense-organs. Theophrastus reasonably complains that sensible qualities will lack causal efficacy if they are identified with these powers of external objects, but Theophrastus' interpretation is mistaken: Plato is not defining the sensible qualities; he is fixing the reference of our sensible-quality terms. Recent historical work on the distinction between primary and secondary qualities has often emphasized the extent to which the authors of this distinction were motivated by an interest in supplanting prevalent, Peripatetic assumptions about the nature of sensible qualities, but Aristotle's theory does not differ significantly from that of Descartes: both identify colors with causally efficacious properties whose natures are revealed by scientific investigation.

It has been proposed by Dawkins, Dennett and others that memes are the units of cultural evolution. We here concentrate on Dennett's account because of the role it plays in his explanation of human consciousness - which is our principal target. Memes are claimed to be replicators that work on Darwinian principles. But in what sense are they replicators, and in what way are they responsible for their own propagation? We argue that their ability to replicate themselves is severely limited, (...) particularly in the case of language-borne memes. We contend, too, that the theory has unacceptable consequences for the role of design in accounting for cultural change, unless we seriously want to entertain the thought that design has as little relevance to cultural evolution as it does to the evolution of species. Finally, we argue that the account fails to do justice to the complexities of social practices. (shrink)

Several different quantum gravity research programmes suggest, for various reasons, that spacetime is not part of the fundamental ontology of physics. This gives rise to the problem of empirical coherence: if fundamental physical entities do not occupy spacetime or instantiate spatiotemporal properties, how can fundamental theories concerning those entities be justified by observation of spatiotemporally located things like meters, pointers and dials? I frame the problem of empirical coherence in terms of entailment: how could a non-spatiotemporal fundamental theory entail spatiotemporal (...) evidence propositions? Solutions to this puzzle can be classified as realist or antirealist, depending on whether or not they posit a non-fundamental spacetime structure grounded in or caused by the fundamental structure. These approaches place different constraints on our everyday concepts of space and time. Applying lessons from the philosophy of mind, I argue that only realism is both conceptually plausible and suitable for addressing the problem at hand. I suggest a role functionalist version of realism, which is consistent with both grounding and causation, and according to which our everyday concepts reveal something of the true nature of emergent spacetime.

Infinite time Turing machines extend the operation of ordinary Turing machines into transfinite ordinal time. By doing so, they provide a natural model of infinitary computability, a theoretical setting for the analysis of the power and limitations of supertask algorithms.
