Reasoning about situations we take to be impossible is useful for a variety of theoretical purposes. Furthermore, using a device of impossible worlds when reasoning about the impossible is useful in the same sorts of ways that the device of possible worlds is useful when reasoning about the possible. This paper discusses some of the uses of impossible worlds and argues that commitment to them can and should be had without great metaphysical or logical cost. The paper then provides an (...) account of reasoning with impossible worlds, by treating such reasoning as reasoning employing counterpossible conditionals, and provides a semantics for the proposed treatment.

In this much-anticipated book, Jonathan Dancy offers the only available full-scale treatment of particularism in ethics, a view with which he has been associated for twenty years. Dancy now presents particularism as the view that the possibility of moral thought and judgement does not in any way depend on an adequate supply of principles. He grounds this claim on a form of reasons-holism, holding that what is a reason in one case need not be any reason in another, and maintaining (...) that moral reasons are no different in this respect from others. Ethics Without Principles offers detailed treatment and criticism of opposing positions of all sorts, with useful summaries. It also contains three chapters on the nature of what Dancy calls 'contributory' reasons, which, though the topic of much interest at the moment, are not often discussed in anything like the detail given here. And it offers a distinctive form of value-holism to go with the holism of reasons. As Dancy's definitive statement on particularism, the book will be required reading for all those working on moral philosophy and ethical theory. (shrink)

In this essay I present a new version of the Paradox of the Knower and show that this new paradox vitiates a certain argument against epistemic closure. I then prove a theorem that relates the new paradox to epistemological scepticism. I conclude by assessing the use of the Knower in arguments against syntactical treatments of knowledge.

The Problems of Mental Causation. Functionalism in the philosophy of mind identifies mental states with their dispositional connections with other mental states, perceptions and actions. Many theories of the mind have sailed under the Functionalist flag. But what I take to be essential to Functionalism is that mental states are individuated causally: the reality of mental states depends essentially on their causal efficacy.

In focusing on indexicals and proper names and on the different ways in which their references are fixed, I illustrate how our linguistic practice rests on context, broadly construed. The following theses are discussed and defended: • There are two main kinds of information: (i) anchored information, i.e. the information one gathers in using and entertaining indexical expressions and (ii) unanchored information, i.e. the information one may gain in hearing a proper name. • Indexical expressions differ from proper names; this (...) difference relies on the differing ways in which extra‐linguistic context enters the scene. • The Kaplanian framework in particular, and the framework of direct reference in general, are best understood and appreciated against the background of a Wittgensteinian conception of language.

In this response to D. Z. Phillips's critique of my interpretation of Wittgenstein's view of magic and ritual, I counter Phillips's claim that I have misrepresented the Wittgensteinian view of ritual, consider the instrumentalist dimension of the Remarks on Frazer's Golden Bough, offer some objections to Phillips's expressivist view that a ritual ‘says itself’, and detect obscurantism in his approach to the study of religion.

Lewis claims that Martin’s cases indeed refute the simple conditional analysis of dispositions and proposes the reformed conditional analysis that is purported to overcome them. In this paper I will first argue that Lewis’s defense of the reformed analysis can be understood to invoke the concepts of disposition-specific stimulus and manifestation. I will go on to argue that advocates of the simple analysis, just like Lewis, can also defend their analysis from alleged counterexamples including Martin’s cases by invoking the concepts (...) of disposition-specific stimulus and manifestation. This means that Lewis’s own necessary defense of the reformed analysis invalidates his motivation of it. Finally, I will argue that we have a good reason to favor the simple analysis over Lewis’s analysis. (shrink)

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)

In this sequence of philosophical essays about natural science, the author argues that fundamental explanatory laws, the deepest and most admired successes of modern physics, do not in fact describe regularities that exist in nature. Cartwright draws from many real-life examples to propound a novel distinction: that theoretical entities, and the complex and localized laws that describe them, can be interpreted realistically, but the simple unifying laws of basic theory cannot.

This volume offers an unusual variety of topics presented during the sixth annual Oberlin Colloquium in Philosophy.

This paper discusses the mistake of understanding the laws and concepts of thermodynamics too literally in the foundations of statistical mechanics. Arguing that this error is still made in subtle ways, the article explores its occurrence in three examples: the Second Law, the concept of equilibrium and the definition of phase transitions.

In the preface, Kim writes hopefully that his introduction to the philosophy of mind is “intended to be accessible to those without a formal background in philosophy”. The blurb at the end is more realistic: Philosophy of Mind is “a textbook for upper-level undergraduates and graduate students”. It is an admirable addition to Westview’s excellent Dimensions of Philosophy series. Brisk, workmanlike chapters profile the usual suspects: behaviorism, the identity theory, mind as computer and as causal structure, mental causation, consciousness, mental (...) content, and reductive and nonreductive physicalism. Each chapter ends with a useful note on further readings. (shrink)

The sceptic about the external world presents us with a paradox: an apparently acceptable argument for an apparently unacceptable conclusion—that we do not know anything about the external world. Some paradoxes, for instance the liar and the sorites, are very hard. The defense of a purported solution to either of these two inevitably deploys the latest in high-tech philosophical weaponry. On the other hand, some paradoxes are not at all hard, and may be resolved without much fuss. They do not (...) contain profound lessons about the human condition. Where should we place the sceptical paradoxes? (shrink)

Numbers and other mathematical objects are exceptional in having no locations in space or time or relations of cause and effect. This makes it difficult to account for the possibility of the knowledge of such objects, leading many philosophers to embrace nominalism, the doctrine that there are no such objects, and to embark on ambitious projects for interpreting mathematics so as to preserve the subject while eliminating its objects. This book cuts through a host of technicalities that have obscured previous (...) discussions of these projects, and presents clear, concise accounts of a dozen strategies for nominalistic interpretation of mathematics, thus equipping the reader to evaluate each and to compare different ones. The authors also offer critical discussion, rare in the literature, of the aims and claims of nominalistic interpretation, suggesting that it is significant in a very different way from that usually assumed.

Much has been written about epistemological skepticism in the last ten or so years, but there remain some unanswered questions concerning the structure of what has become the canonical Cartesian skeptical argument. In this paper, I would like to take a closer look at this structure in order to determine just which epistemic principles are required by the argument.

In chapter 1 of Reason, Truth, and History, Hilary Putnam argues from some plausible assumptions about the nature of reference to the conclusion that it is not possible that all sentient creatures are brains in a vat. If this argument is successful, it seemingly refutes an updated form of Cartesian skepticism concerning knowledge of physical objects. In this paper, I will state what I take to be the most promising interpretation of Putnam's argument. My reconstructed argument differs from an argument (...) strongly suggested by Putnam's text. I will show that the latter argument obviously does not work. The more promising argument which I reconstruct on behalf of Putnam raises some interesting questions about the relation between the contents of one's beliefs and one's environment and about how this relation affects the evaluation of anti-skeptical arguments. I conclude that my reconstructed argument ultimately fails as a response to Cartesian skepticism: the argument engenders a skepticism about knowledge of meaning, or propositional content, which undercuts its anti-skeptical force.

Artificial intelligence research has foundered on the issue of representation. When intelligence is approached in an incremental manner, with strict reliance on interfacing to the real world through perception and action, reliance on representation disappears. In this paper we outline our approach to incrementally building complete intelligent Creatures. The fundamental decomposition of the intelligent system is not into independent information processing units which must interface with each other via representations. Instead, the intelligent system is decomposed into independent and parallel activity (...) producers which all interface directly to the world through perception and action, rather than interface to each other particularly much. The notions of central and peripheral systems evaporateeverything is both central and peripheral. Based on these principles we have built a very successful series of mobile robots which operate without supervision as Creatures in standard office environments. (shrink)

Tyler Burge has argued that one has an a priori prima facie entitlement to believe in the truth of what one takes to have been presented as true by an interlocutor. This thesis, however, is problematic, since the alleged a priori prima facie entitlement to believe in the truth of our seeming understanding of things presented as true to us, rests on the possibility of determining assertoric force on a purely intellectual basis. This thesis is not plausible and Burge's analogy (...) from memory does not support it. Two routes for defending Burge's thesis of the a priori prima facie entitlement to believe in the truth of what has been asserted can be identified: the Transcendental Route and the Intrinsic Rationality Route. David Lewis' account of linguistic convention would serve as a transcendental argument for the a priori prima facie entitlement to believe in the truth of what has been asserted, but flaws in Lewis' theory leave us deprived of any good transcendental argument for such an entitlement. The Intrinsic Rationality Route is in better standing, but we have yet to see an argument for why we should resort to that measure. (shrink)

I. Recent years have witnessed a great resurgence of interest in the writings of the later Wittgenstein, especially with those passages roughly, Philosophical Investigations p)I 38 — 242 and Remarks on the Foundations of mathematics, section VI that are concerned with the topic of rules. Much of the credit for all this excitement, unparalleled since the heyday of Wittgenstein scholarship in the early IIJ6os, must go to Saul Kripke's I4rittgenstein on Rules and Private Language. It is easy to explain why. (...) To begin with, the dialectic Kripke uncovered from Wittgenstein's.. (shrink)

In this note, I will discuss one issue concerning the main argument of Mind in a Physical World (Kim, 1998), the Causal Exclusion Argument. The issue is whether it is a consequence of the Causal Exclusion Argument that all macro level causation (that is, causation above the level of fundamental physics) is an illusion, with all of the apparent causal powers of mental and other macro properties draining into the bottom level of physics. I will argue that such a consequence (...) would give us reason to reject the Causal Exclusion Argument. But there is also a stronger challenge, the charge that, if there is no bottom level of physics, the Causal Exclusion Argument has the consequence that “causal powers would drain away into a bottomless pit and there wouldn’t be any causation anywhere.” (81--page numbers that are not attributed to other works are to Kim, 1998).

To be able to produce and understand metaphorical statements is nothing much to boast about: these familiar skills, which children seem to acquire as they learn to talk, are perhaps no more remarkable than our ability to tell and to understand jokes. How odd then that it remains difficult to explain what we do in grasping metaphorical statements. In a provocative paper, "What Metaphors Mean,"1 Donald Davidson has recently charged many students of metaphor, ancient and modern, with having committed a (...) "central mistake." According to him, there is "error and confusion" in claiming "that a metaphor has, in addition to its literal sense or meaning, another sense or meaning." The guilty include "literary critics like Richards, Empson, and Winters; philosophers from Aristotle to Max Black; psychologists from Freud and earlier to Skinner and later; and linguists from Plato to Uriel Weinreich and George Lakoff." Good company, if somewhat mixed. The error to be extirpated is the "idea that a metaphor has a special meaning" . If Davidson is right, much that has been written about metaphor might well be consigned to the flames. Even if he proves to be wrong, his animadversions should provoke further consideration of the still problematic modus operandi of metaphor. · 1. In "What Metaphors Mean," Critical Inquiry 5 : 31-47.

Contemporary hybrid logic is based on the idea of using formulas as terms, an idea invented and explored by Arthur Prior in the mid-1960s. But Prior’s own work on hybrid logic remains largely undiscussed. This is unfortunate, since hybridisation played a role that was both central to and problematic for his philosophical views on tense. In this paper I introduce hybrid logic from a contemporary perspective, and then examine the role it played in Prior’s work.

In my 'Dispositions and Antidotes', The Philosophical Quarterly, 48 (1998), I raise an objection to the conditional analysis of dispositions, both in its simple formulation and in a more sophisticated version due to David Lewis, The Philosophical Quarterly, 47 (1997). The objection suggests that a disposition may be continuously present and the appropriate stimulus occur without the manifestation occurring, because some outside influence, an antidote, interferes. Gundersen in The Philosophical Quarterly, 50 (2000), argues that my objection rests on an equivocation (...) about which object possesses the disposition and more particularly on an equivocation about the context in which the events referred to take place, and that when the equivocation is resolved the counter-example disappears. I respond by showing that the counter-example does remain if we take contextual and mereological issues into account, and I conclude by remarking that the difference with Lewisdepends on whether certain features are seen as significant for the semanticsand metaphysics of dispositions or as merely characteristic of the pragmaticsof common usage.

In ‘Finkish Dispositions’1 David Lewis proposes an analysis of dispositions which improves on the simple conditional analysis. In this paper I show that Lewis’ analysis still fails. I also argue that repairs are of no avail, and suggest why this is so.
