This book proposes guidelines for constructing and evaluating definitions of terms, i.e. words or phrases of general application. The guidelines extend to adoption of nomenclature. The book is meant to be a practical guide for people who find themselves in their daily lives or their employment producing or evaluating definitions of terms. It can be consulted rather than being read through. The book’s theoretical framework is a distinction, due to Robert H. Ennis, of three dimensions of definitions: the act of (...) the definer, the content of the definition, and its form. The act of a definer is what the definer does in defining a term; the book distinguishes, following Ennis, three basic acts of defining: reporting, stipulating, and advocating. The content of a definition is in one sense the information that the definition conveys and in another sense the words in its defining part. The form of a definition is the way it is expressed, for example as a definition by genus and differentia. (shrink)

In this book, I present the results of an investigation which began with an extended stay at Oxford's Balliol College during the first half of 1995. My visit to Oxford was made possible by a grant from the Spanish Ministerio de Educaci6n y Ciencia. My sincere thanks go to Joseph Raz who served as my supervisor in Oxford. For several points of the present study, conversations with Timothy Endicott in Oxford were also of great help. The book is part of (...) a larger project of investigation, directed by Albert Calsami glia, which is a joint effort of a group of legal philosophers from the Universitat Pom peu Fabra and the Universitat de Girona, and which also receives financial support from the Spanish Ministerio de Educaci6n y Ciencia. An earlier version of the manuscript was presented in June 1996 to the selection committee for a tenured professorship in Legal Philosophy at the Universitat de Girona. The members of the committee were Francisco Laporta, Albert Calsamiglia, Gregorio Peces-Barba, Camilo J. Cela Conde, and Francesca Puigpelat. I am grateful to all of them for their comments, which have been extremely useful in preparing the final ver sion of this book. (shrink)

Can humans and artificial intelligences share concepts and communicate? Making AI Intelligible shows that philosophical work on the metaphysics of meaning can help answer these questions. Herman Cappelen and Josh Dever use the externalist tradition in philosophy to create models of how AIs and humans can understand each other. In doing so, they illustrate ways in which that philosophical tradition can be improved. The questions addressed in the book are not only theoretically interesting, but the answers have pressing practical implications. (...) Many important decisions about human life are now influenced by AI. In giving that power to AI, we presuppose that AIs can track features of the world that we care about (for example, creditworthiness, recidivism, cancer, and combatants). If AIs can share our concepts, that will go some way towards justifying this reliance on AI. This ground-breaking study offers insight into how to take some first steps towards achieving Interpretable AI. (shrink)

Communication and content presents a comprehensive and foundational account of meaning based on new versions of situation theory and game theory. The literal and implied meanings of an utterance are derived from first principles assuming little more than the partial rationality of interacting agents. New analyses of a number of diverse phenomena – a wide notion of ambiguity and content encompassing phonetics, syntax, semantics, pragmatics, and beyond, vagueness, convention and conventional meaning, indeterminacy, universality, the role of truth in communication, semantic (...) change, translation, Frege’s puzzle of informative identities – are developed. Communication, speaker meaning, and reference are defined. Frege’s context and compositional principles are generalized and reconciled in a fixed-point principle, and a detailed critique of Grice, several aspects of Lewis, and some aspects of the Romantic conception of meaning are offered. Connections with other branches of linguistics, especially psycholinguistics, sociolinguistics, historical linguistics, and natural language processing, are explored. -/- The book will be of interest to scholars in philosophy, linguistics, artificial intelligence, and cognitive science. It should also interest readers in related fields like literary and cultural theory and the social sciences. (shrink)

The book discusses the structure, content, and evaluation of cosmological arguments. The introductory chapter investigates features essential to cosmological arguments. Traditionally, cosmological arguments are distinguished by their appeal to change, causation, contingency or objective becoming in the world. But none of these is in fact essential to the formulation of cosmological arguments. Chapters 1-3 present a critical discussion of traditional Thomistic, Kalam, and Leibnizian cosmological arguments, noting various advantages and disadvantages of these approaches. Chapter 4 offers an entirely new approach (...) to the cosmological argument - the approach of theistic modal realism. The proper explananda of cosmological arguments on this approach is not change, causation, contingency or objective becoming in the world. The proper explananda is the totality of metaphysical reality - all actualia and all possibilia. The result is the most compelling and least objectionable version of the cosmological argument.

I argue for a soft compatibilist theory of free will, i.e., such that free will is compatible with both determinism and indeterminism, directly opposite hard incompatibilism, which holds free will incompatible both with determinism and indeterminism. My intuitions in this book are primarily based on an analysis of meditation, but my arguments are highly syncretic, deriving from many fields, including behaviorism, psychology, conditioning and deconditioning theory, philosophy of language, philosophy of mind, simulation theory, etc. I offer a causal/functional analysis of (...) meta-mental control, or 'metacausality', cashed out in counterfactual terms, to solve what I call the easy problem of free will.

This book combines insights from philosophy and linguistics to develop a novel framework for theorizing about linguistic meaning and the role of context in interpretation. A key innovation is to introduce explicit representations of context — assignment variables — in the syntax and semantics of natural language. The proposed theory systematizes a spectrum of “shifting” phenomena in which the context relevant for interpreting certain expressions depends on features of the linguistic environment. Central applications include local and nonlocal contextual dependencies with (...) quantifiers, attitude ascriptions, conditionals, questions, and relativization. The result is an innovative, philosophically informed compositional semantics compatible with the truth-conditional paradigm. (shrink)

What is the modal significance of sortal concepts? It is generally accepted that sortal concepts provide persistence conditions with modal implications that are de re, and not merely de dicto. I do not think that this important assumption has received the scrutiny that it deserves. In this paper, I examine the contrast between a ‘pure de dicto’ theory of the persistence conditions associated with sortal concepts and a variety of de re theories, both essentialist and non-essentialist. I conclude that although (...) there is a defensible argument against the pure de dicto theory, it has two interesting implications. First, the argument lends no support to an essentialist version of the de re theory. Secondly, it appears to support the rejection of the pure de dicto theory only by a theorist who is also a pluralist about coincidence. Hence it appears to provide no justification for the rejection of the pure de dicto theory on the part of a contingent identity theorist. (shrink)

In this paper I examine the ritual life of Abraham as it is presented in the book of Genesis. Paying close attention to the language of the narrative, I try to reconstruct the evolving philosophical theology that seems to underlie the modes of worship that Abraham develops over time. Read in this light, the life of Abraham can help us to rethink the extent to which theistic religiosity requires a personal God, and the extent to which it can survive in (...) the face of a more austere impersonal theology.

Two things are done in this paper. First, a modal logic in which one can quantify over both objects and concepts is presented; a semantics and a tableau system are given. It is a natural modal logic, extending standard versions, and capable of addressing several well-known philosophical difficulties successfully. Second, this modal logic is used to introduce a rather different way of looking at relational databases. The idea is to treat records as possible worlds, record entries as objects, and attributes (...) as concepts, in the modal sense. This makes possible an intuitively satisfactory relational database theory. It can be extended, by the introduction of higher types, to deal with multiple-valued attributes and more complex things, though this is further than we take it here. (shrink)

En este trabajo, critico una estrategia argumental que ha sido utilizada para defender la concepción de la rigidez para expresiones predicativas entendida como identidad de lo designado en los distintos mundos posibles. Se trata de una estrategia basada en la suposición de que las descripciones tendrían la capacidad de designar individuos inusuales en la misma medida en que ciertas expresiones predicativas descriptivas serían capaces de designar propiedades inusuales. Señalo que esta suposición no es compatible con ciertos principios que gobiernan el (...) funcionamiento semántico de las descripciones y con la verdad intuitiva de ciertas predicaciones que las incluyen.In this paper, I criticize an argumentative strategy that has been used in the literature to defend the view according to which rigidity for predicative expressions should be understood as identity of designation across possible worlds. It is a strategy that is based on the supposition that definite descriptions could designateunusual individuals just as well as some descriptive predicative expressions are able to designate unusual properties. I point out that this presupposition is at odds with some principles governing the semantic behaviour of definite descriptions and with the intuitive truth of some predications that include them.

Philosophers have often wanted to state a principled way of demarcating empirical from non-empirical thought. This was a major concern of the Vienna Circle. In my view, this is an important intellectual project. Although it is not so common now to address the issue directly, it hovers in the background of many discussions. Non-empirical thought comes in different kinds. Perhaps some is a priori. Common candidates are mathematical, logical, modal and moral thought. Some non-empirical thought might be non-cognitive. Common candidates (...) are moral, aesthetic and religious thought. Or some non-empirical thought might be pseudo-empirical. Common candidates are astrological, theistic, Marxist or psychoanalytic thought; such thought masquerades as empirical, but in fact is not. These are all ways that thought can fail to be empirical. Here I shall focus for the most part on the case of morality, where there has been a lively debate about the empirical status of moral thought. I shall probe the prospects for a demarcation principle that can be used to decide whether or not moral thought is empirical. Some philosophers have recently presented what seems like a compelling case for thinking that moral thought is empirical, and so engaging with their arguments will raise the issue of what the empirical/nonempirical distinction amounts to, and also the issue of how to tell which forms of thought are empirical and which are not.

I defend the view that strong psychophysical superveniences is necessary and sufficient to explain the causal efficacy of mental properties. I employ factual and counterfactual conditionals as defeasible criteria of causal efficacy. And I also deal with certain problems arising from disjunctive and conjunctive properties.

I exist. That is something I know. Most philosophers think that Descartes was right that each of us knows that we exist. Furthermore most philosophers agree with Descartes that there is something special about how we know it. Agreement ends there. There is little agreement about exactly what is special about this knowledge. I shall present an account that is in some respects Cartesian in spirit, although I shall not pursue interpretive questions very far. On this account, I know that (...) I exist a priori; and I shall advance an explanation of how this a priori knowledge is possible and actual. I then consider the question of whether the belief that I exist is justified and, if so, how. I argue that the situation is different in important ways from the knowledge that I exist. (shrink)

A widely held view about Fregean Sense has it that the determination of a sign's referent by the sign's sense is achieved viasatisfaction: the sense specifies a condition (or set of conditions) and the referent is that entity, if any, which uniquely satisfies that (set of) condition(s). This is usually held in conjunction with the claim that the sense is existentially and qualitatively independent of the referent: if the referent did not exist, or did not uniquely satisfy the sense, the (...) sense would still exist and would still specify the same condition(s) that it actually does (and might determine a different referent than its actual one). Proponents of this view give several reasons for holding it. I describe these reasons and argue that they are not convincing. More generally, I try to show that the notion of satisfaction has no useful application within Frege's system. I then suggest an alternative account of the determination of a referent by a sense that I think is truer to Frege and more illuminating. Compared to the satisfaction view, my account construes determination as a more naturalistic and epistemically real relation between speakers and things in the world. (shrink)

Abstract: In this essay I outline a radical kind of virtue theory I call exemplarism, which is foundational in structure but which is grounded in exemplars of moral goodness, direct reference to which anchors all the moral concepts in the theory. I compare several different kinds of moral theory by the way they relate the concepts of the good, a right act, and a virtue. In the theory I propose, these concepts, along with the concepts of a duty and of (...) a good life, are defined by reference to exemplars, identified directly through the emotion of admiration, not through a description. It is an advantage of the theory that what makes a good person good is not given a priori but is determined by empirical investigation. The same point applies to what good persons do and what states of affairs they aim at. The theory gives an important place to empirical investigation and narratives about exemplars analogous to the scientific investigation of natural kinds in the theory of direct reference. (shrink)

Supporters of the A-theory of time sometimes refer to an alleged experience of the passage of time in support of their theory. In this paper I argue that it is an illusion that we experience the passage of time, for such an experience is impossible. My argument relies on the general assertion that experience is contingent, in the sense that if it is possible to experience the passage of time, it is also possible to experience that time does not pass. (...) Having established this claim, I argue that it is impossible to experience that time does not pass, and hence that it is impossible to experience the passage of time. (shrink)

The Kripkean metaphysical modality (i.e. possibility and necessity) is one of the most important concepts in contemporary analytic philosophy and is the basis of many metaphysical speculations. These metaphysical speculations frequently commit to entities that do not belong to this physical universe, such as merely possible entities, abstract entities, mental entities or qualities not realizable by the physical, which seems to contradict naturalism or physicalism. This paper proposes a naturalistic interpretation of the Kripkean modality, as a naturalist’s response to these (...) metaphysical speculations. It will show that naturalism can accommodate the Kripkean metaphysical modality. In particular, it will show that naturalism can help to resolve the puzzles surrounding Kripke’s a posteriori necessary propositions and a priori contingent propositions. (shrink)

Essence and causation are fundamental in metaphysics, but little is said about their relations. Some essential properties are of course causal, as it is essential to footprints to have been caused by feet. But I am interested less in causation's role in essence than the reverse: the bearing a thing's essence has on its causal powers. That essencemight make a causal contribution is hinted already by the counterfactual element in causation; and the hint is confirmed by the explanation essence offers (...) of something otherwise mysterious, namely, how events exactly alike in every ordinary respect, like the bolt'ssuddenly snapping and its snapping per se, manage to disagree in what they cause. Some prior difference must exist between these events to make their causal powers unlike. Paradoxically, though, it can only be in point of a property, suddenness, which both events possess in common. Only by postulating a difference in themanner — essential or accidental — of the property's possession is the paradox resolved. Next we need an account of causation in which essence plays an explicit determinative role. That account, based on the idea that causes should becommensurate with their effects, is thatx causesy only if nothing essentially poorer would have done, and nothing essentially richer was needed.

It is the purpose of this article to explicate the logical implications of a television analogy for perception, first suggested by John R. Smythies (1956). It aims to show not only that one cannot escape the postulation of qualia that have an evolutionary purpose not accounted for within a strong functionalist theory, but also that it undermines other anti-representationalist arguments as well as some representationalist ones.

Non-Identity arguments have a pervasive but sometimes counter-intuitive grip on certain key areas in ethics. As a result, there has been limited success in supporting the alternative view that our choices concerning future generations can be considered harmful on any sort of person-affecting principle. However, as the Non-Identity Problem relies overtly on certain metaphysical assumptions, plausible alternatives to these foundations can substantially undermine the Non-Identity argument itself. In this paper, I show how the pervasive force and nature of Non-Identity arguments (...) rely upon a specific adoption of a theory of modality and identity and how adopting an alternative account of modality can be used to reject many conclusions formed through Non-Identity type arguments. By using Lewis’s counterpart-theoretic account to understand ways we might have been, I outline the basis of a modal account of harm that incorporates a person-affecting aspect. This, in turn, has significant implications for ethical decision-making in areas such as reproductive choice and the welfare of future generations. (shrink)

This paper examines the potential for abstracting propositions – an as yet untested way of defending the realist thesis that propositions as abstract entities exist. I motivate why we should want to abstract propositions and make clear, by basing an account on the neo-Fregean programme in arithmetic, what ontological and epistemological advantages a realist can gain from this. I then raise a series of problems for the abstraction that ultimately have serious repercussions for realism about propositions in general. I first (...) identify problems about the number of entities able to be abstracted using these techniques. I then focus on how issues of language relativity result in problems akin to the Caesar problem in arithmetic by exposing circularity and modal concern over the status of the criterion of identity for propositions.

Laurence BonJour has recently proposed a novel and interesting approach to the problem of induction. He grants that it is contingent, and so not a priori, that our patterns of inductive inference are reliable. Nevertheless, he claims, it is necessary and a priori that those patterns are highly likely to be reliable, and that is enough to ground an a priori justification induction. This paper examines an important defect in BonJour's proposal. Once we make sense of the claim that inductive (...) inference is "necessarily highly likely" to be reliable, we find that it is not knowable a priori after all. (shrink)

This paper argues for the presence in Plato’s work of a conception of thinking central to which is what I call the Transparency View. According to this view, in order for a subject to think of a given object, the subject must represent that object just as it is, without inaccuracy or distortion. I examine the ways in which this conception influences Plato’s epistemology and metaphysics and explore some ramifications for contemporary views about mental content.

Few philosophers today doubt the importance of some notion of rigid designation, as suggested by Kripke and Putnam for names and natural kind terms. At the very least, most of us want our theories to be compatible with the most plausible elements of that account. Anaphoric theories of reference have gained some attention lately, but little attention has been given to how they square with rigid designation. Although the differences between anaphoric theories and many interpretations of the New Theory of (...) reference are substantial, I argue that rigid designation and anaphoric theories can be reconciled with one another and in fact complement one another in important ways.

Causal theories of reference in the philosophy of language and philosophy of science have suggested that it could resolve lingering worries about incommensurability between theoretical claims in different paradigms, to borrow Kuhn’s terms. If we co-refer throughout different paradigms, then the problems of incommensurability are greatly diminished, according to causal theorists. I argue that assuring ourselves of that sort of constancy of reference will require comparable sorts of cross-paradigm affinities, and thus provides us with no special relief on this problem. (...) Suggestions on how to think about rigid designation across paradigms are included. (shrink)

Demonstrative noun phrases (e.g., that guy , this ) are of interest to philosophers of language and semanticists because they are sensitive to demonstrations or speaker intentions. The interpretation of a demonstrative therefore sheds light on the role of the context in natural language semantics. This survey reviews two types of approaches to demonstratives: Kaplan's direct reference treatment of demonstratives and other indexicals, and recent challenges to Kaplan's approach that focus on less obviously context-sensitive uses of demonstratives. The survey then (...) covers selected research on demonstratives in linguistics. This research offers new empirical puzzles and contrasting theoretical approaches to demonstratives. (shrink)

What has come to be known as “a priori physicalism” is the thesis, roughly, that the non-physical truths in the actual world can be deduced a priori from a complete physical description of the actual world. To many contemporary philosophers, a priori physicalism seems extremely implausible. In this paper I distinguish two kinds of a priori physicalism. One sort – strict a priori physicalism – I reject as both unmotivated and implausible. The other sort – liberal a priori physicalism – (...) I argue is both motivated and plausible. This variety of a priori physicalism insists that the necessitation of non-physical truths by the physical facts must be underwritten in a certain fashion by a priori knowledge, but the a priori knowledge need not amount to a simple deduction of the non-physical truths from a complete physical description of the world. Further, this sort of liberal a priori physicalism has the advantage that it offers hope for a genuinely satisfying account of how the physical facts manage to necessitate the facts about phenomenal consciousness – thereby in effect solving the “hard problem” of consciousness. The first half of the paper sets out the motivation for liberal a priori physicalism and its superiority to the strict version; the second half presents one strategy available to the liberal a priori physicalist for showing how consciousness can be accommodated in a purely physical world.

This paper argues that the principle of necessary identity (f)(g)(f=g then necessarily f=g) cannot be maintained, At least in second order form. A paradox based upon scientific definitional practice is introduced to demonstrate this. A non-Fregean reading of standard contingent identity semantics is provided to explain how such 'definition breaking' works.

Perry, in this lucid, deep, and entertaining book , supposes that type-identity physicalism is antecedently plausible, and that rejecting this thesis requires good reason (this is.

When attempting to determine which of our acts affect future generations and which affect the identities of those who make up such generations, accounts of personal identity that privilege psychological features and person affecting accounts of morality, whilst highly useful when discussing the rights and wrongs of acts relating to extant persons, seem to come up short. On such approaches it is often held that the intuition that future persons can be harmed by decisions made prior to their existence is (...) mistaken as identity is a most fragile thing with even the smallest differences in the conditions under which we procreate affecting not the interests of distinct future persons, but the identities of those who will come to exist in the future. Within this paper I reject this view, holding that a subscription to these two accounts need not result in the conclusion that virtually all acts relating to possible persons are permitted. Further, I argue that such accounts may in fact allow a great deal more scope for the determination of prenatal harms than accounts of personal identity that privilege physical features. Finally, by interpreting claims regarding causal identity such as Parfit’s Time Dependence Claim in terms of Counterpart Theory I suggest that a solution to the non-identity problem can be found in the acceptance of, as relevant in prenatal cases, three kinds of objective similarity relations: Biological, Environmental and Decisional counterpart relations.

This paper explains and defends the idea that metaphysical necessity is the strongest kind of objective necessity. Plausible closure conditions on the family of objective modalities are shown to entail that the logic of metaphysical necessity is S5. Evidence is provided that some objective modalities are studied in the natural sciences. In particular, the modal assumptions implicit in physical applications of dynamical systems theory are made explicit by using such systems to define models of a modal temporal logic. Those assumptions (...) arguably include some necessitist principles. -/- Too often, philosophers have discussed ‘metaphysical’ modality — possibility, contingency, necessity — in isolation. Yet metaphysical modality is just a special case of a broad range of modalities, which we may call ‘objective’ by contrast with epistemic and doxastic modalities, and indeed deontic and teleological ones (compare the distinction between objective probabilities and epistemic or subjective probabilities). Thus metaphysical possibility, physical possibility and immediate practical possibility are all types of objective possibility. We should study the metaphysics and epistemology of metaphysical modality as part of a broader study of the metaphysics and epistemology of the objective modalities, on pain of radical misunderstanding. Since objective modalities are in general open to, and receive, natural scientific investigation, we should not treat the metaphysics and epistemology of metaphysical modality in isolation from the metaphysics and epistemology of the natural sciences. -/- In what follows, Section 1 gives a preliminary sketch of metaphysical modality and its place in the general category of objective modality. Section 2 reviews some familiar forms of scepticism about metaphysical modality in that light. Later sections explore a few of the many ways in which natural science deals with questions of objective modality, including questions of quantified modal logic. (shrink)

Quine (1960, Word and object. Cambridge, Mass.:MIT Press, ch. 2) claims that there are a variety of equally good schemes for translating or interpreting ordinary talk. ‘Rabbit’ might be taken to divide its reference over rabbits, over temporal slices of rabbits, or undetached parts of rabbits, without significantly affecting which sentences get classified as true and which as false. This is the basis of his famous ‘argument from below’ to the conclusion that there can be no fact of the matter (...) as to how reference is to be divided. Putative counterexamples to Quine’s claim have been put forward in the past (see especially Evans 1975; 1975, Journal of Philosophy, LXXII(13), 343–362. Reprinted in McDowell (Ed.), Gareth Evans: Collected papers. Oxford: Clarendon Press.), and various patches have been suggested (e.g. Wright (1997, The indeterminacy of translation. In C. Wright & B. Hale (Eds.), A companion to the philosophy of language (pp. 397–426). Oxford: Blackwell)). One lacuna in this literature is that one does not find any detailed presentation of what exactly these interpretations are supposed to be. Drawing on contemporary literature on persistence, the present paper sets out detailed semantic treatments for fragments of English, whereby predicates such as ‘rabbit’ divide their reference over four-dimensional continuants (Quine’s rabbits), instantaneous temporal slices of those continuants (Quine’s rabbit-slices) and the simple elements which compose those slices (undetached rabbit parts) respectively. Once we have the systematic interpretations on the table, we can get to work evaluating them. (shrink)

These comments are part of a book symposium on Karen Bennett's book, _Making Things Up_.

Externalism is widely endorsed within contemporary philosophy of mind and language. Despite this, it is far from clear how the externalist thesis should be construed and, indeed, why we should accept it. In this entry I distinguish and examine three central types of externalism: what I call foundational externalism, externalist semantics, and psychological externalism. I suggest that the most plausible version of externalism is not in fact a very radical thesis and does not have any terribly interesting implications for philosophy (...) of mind, whereas the more radical and interesting versions of externalism are quite difficult to support.

Since Hilary Putnam and Saul Kripke's first attacks on traditional, descriptivist theories of natural kind terms, it has become customary to speak of the ‘Putnam-Kripke’ view of meaning and reference. This article argues that this is a mistake, and that Putnam's account of natural kind terms is importantly different from that of Kripke. In particular, Putnam has from the very start been sceptical of Kripke's modal claims, and in later papers he explicitly rejects the proposal that theoretical identity statements are (...) metaphysically necessary (if true). I suggest that this is wholly in line with Putnam's earlier, Quine-inspired writings on general terms, and his preoccupation with the philosophy of science. Moreover, I argue that the picture of general terms that emerges from Putnam's writings is more plausible than that suggested by Kripke. However, contrary to Putnam, I also suggest that Putnam's later views on natural kinds and natural kind terms do not support standard Twin Earth externalism. (shrink)

At the time that Quine wrote "Two Dogmas" an attack on analyticity was considered a simultaneous attack on the very idea of necessary truth. This all changed with Kripke's revival of a non-epistemic, non-linguistic notion of necessity. My paper discusses the question whether we can take Kripke one step further and free analyticity from its epistemic ties, thereby reinstating a notion of analyticity that is immune to Quine's attack, and compatible with his epistemic holism. I discuss this question by examining (...) Tyler Burge's claim that truths of meaning depend on features of the external environment and are a posteriori. I argue that although Burge's construal of analyticity circumvents Quine's objections, it is not well-motivated philosophically and has problematic implications. Kripke's strategy with respect to necessity, I conclude, is not easily transferable to analyticity. (shrink)

ports the thesis that there exist very many universes. The view has found favor with a number of philosophers such as Derek Parfit ~1998!, J. J. C. Smart ~1989! and Peter van Inwagen ~1993!.1 My purpose is to argue that this is a mistake. First let me set out the issue in more detail.

In this paper I distinguish three alternatives to the functionalist account of qualitative states such as pain. The physicalist-functionalist holds that (1) there could be subjects functionally equivalent to us whose mental states differed in their qualitative character from ours, (2) there could be subjects functionally equivalent to us whose mental states lacked qualitative character altogether and (3) there could not be subjects like us in all objective respects whose qualitative states differed from ours. The physicalist-functionalist holds (1) and (3) (...) but denies (2). The transcendentalist holds (1) and (2) and denies (3). I argue that both versions of physicalist-functionalism inherit the problem of property dualism which originally helped to motivate functionalist theories of mind. I also argue that neither version of physicalist-functionalism can distinguish in a principled way between those neurophysiological properties of a subject which are relevant to the qualitative character of that subject's mental states and those which are not. I conclude that the only alternative to a functionalist account of qualitative states is a transcendentalist account and that this alternative is not likely to appeal to the critics of functionalism.
