It was about half a century ago that the mind–body problem, which like much else in serious metaphysics had been moribund for several decades, was resurrected as a mainstream philosophical problem. The first impetus came from Gilbert Ryle'sThe Concept of Mind, published in 1948, and Wittgenstein's well-known, if not well-understood, reflections on the nature of mentality and mental language, especially in hisPhilosophical Investigationswhich appeared in 1953. The primary concerns of Ryle and Wittgenstein, however, focused on the logic of mental discourse rather than the metaphysical issue of how our mentality is related to our bodily nature. In fact, Ryle and Wittgenstein would have regarded, each for different reasons, the metaphysical problem of the mind-body relation as arising out of deplorable linguistic confusions and not amenable to intelligible discussion. There was C. D. Broad's earlier and much neglected classic,The Mind and Its Place in Nature, which appeared in 1925, but this work, although robustly metaphysical, failed to connect with, and shape, the mind–body debate in the second half of this century.

Thoroughly updated, the second edition of this highly successful textbook continues to represent the most comprehensive and authoritative collection of canonical readings in metaphysics. In addition to updated material from the first edition, it presents entirely new sections on ontology and the metaphysics of material objects. One of the most comprehensive and authoritative metaphysics anthologies available - now updated and expanded Offers the most important contemporary works on the central issues of metaphysics Includes new sections on ontology and the metaphysics of material objects, as well as readings on the topics of fictionalism, fundamentality, tropes, vague identity, temporary intrinsics, stage theory, and composition Surpasses other anthologies in its combination of contributions from leading metaphysicians and a younger generation of "rising-stars"

Jackson says that the form of physicalism that I recommend, with certain emendations he believes are necessary, turns out to be none other than the “Australian” type-type identity theory of J.J.C. Smart and others. About this, too, I have no serious disagreement, although Jackson’s claim appears to depend, at least in part, on a certain chosen reading of the texts involved. In fact, one point of similarity may be worth noting. As I take it, one special feature of the “Australian” type identity theory is the claim that mental-physical identities are contingent, not necessary. Suppose M has a single physical realizer, P. On my account, the statement that M = P is not metaphysically or logically necessary. It is contingent since the statement that P realizes M is contingent. This is so because for P to realize M is for it to fulfill the causal specification that defines M, and what causal relations P actually enters into is a question that depends on the laws prevailing in a given world. Thus, P may be a realizer of M in this world but perhaps not in another in which different laws hold; in some worlds M may have no realizers at all. None of this is in violation of the idea that identities are necessary. For, according to me, if M has realizers, M is a functional property defined by a causal specification. This means that “M” is not a rigid designator, though it is, as we might call it, “nomologically rigid” or “semi-rigid”.

Une des doctrines centrales de l’émergentisme est la thèse selon laquelle certaines propriétés d’un tout sont émergentes, en ce sens qu’elles sont irréductibles aux propriétés de base dont elles émergent — c’est-à-dire qu’elles ne peuvent ni être prédites, ni être expliquées à partir de leurs conditions sousjacentes. Pour comprendre et évaluer cette thèse correctement, il est essentiel que nous disposions d’un concept adéquat de réduction. Nous examinons d’abord le modèle classique de la réduction interthéorique de Nagel, et nous soutenons qu’il ne nous fournit pas une base adéquate pour comprendre la thèse émergentiste. Nous proposons ensuite un autre modèle de réduction, celui de la « réduction fonctionnelle », et nous montrons qu’il constitue une base adéquate permettant d’évaluer la thèse émergentiste. Nous concluons avec une brève discussion de la question de savoir si les propriétés phénoménales d’expériences conscientes, ou qualia , sont émergentes.A central doctrine of emergentism is the thesis that some properties of wholes are emergent in the sense that they are irreducible to the “basal” properties from which they emerge — that is, they are neither predictable nor explainable in terms of their underlying conditions. To understand and properly evaluate this claim, it is essential that we have at hand an appropriate concept of reduction. This paper first examines the classic Nagel model of inter- theoretic reduction and finds it wanting as a basis for understanding the emergentist claim. Another model of reduction, “functional reduction”, is proposed, and it is argued that this model does provide an appropriate basis for evaluating the claim that certain properties of wholes are emergent. The paper closes with a brief discussion of the question whether qualia , or the phenomenal properties of conscious experience, are emergent

For the physicalist, the mind-body problem is the problem of finding a place for the mind in a world that is fundamentally physical. What does “fundamentally physical” mean? I think any physicalist will accept at least the following two claims. First, the world contains nothing but bits of matter and aggregates of bits of matter. There are no Cartesian souls, or Hegelian spirits, or neo-vitalist entelechies—as the emergentist C. Lloyd Morgan put it, no “alien influx” into the natural order. This ontological thesis is sometimes called “ontological physicalism”. Second, we have the supervenience thesis: physical facts determine all the facts, and the physical properties of a thing determine all its properties. At this point, then, the world looks like this: all the things that exist are physical things—either basic bits of matter or wholly made up of bits of matter. These physical things have properties. What properties? First, there are basic physical properties, like mass, size, shape, electric charge, and so on—properties and magnitudes in terms of which laws of physics are formulated. But some properties of complex physical systems, like biological organisms, seem prima facie nonphysical—at least, they are not among the properties investigated in physics or the physical sciences. Prominent among them are mental properties—beliefs, desires, sensations, emotions, and the rest. The supervenience thesis says that such properties are fixed by the physical properties of the systems that have them; once the physical properties of a system are fixed, that fixes all of its properties. And yet property dualists, or nonreductive physicalists, maintain that although certain non-physical properties are determined by physical properties, they are irreducible to, and remain distinct from, physical properties. Although thoughts and pains are determined by the biology, and ultimately physicochemistry, of an organism, they are not biological/physical properties themselves, and there exists a special autonomous science of psychology, or cognitive science, that is responsible for investigating them.

This paper offers a critique of the view that causation can be analyzed in terms of explanation. In particular, the following points are argued: a genuine explanatory analysis of causation must make use of a fully epistemological-psychological notion of explanation; it is unlikely that the relatively clear-cut structure of the causal relation can be captured by the relatively unstructured relation of explanation; the explanatory relation does not always parallel the direction of causation; certain difficulties arise for any attempt to construct a nonrelativistic relation of causation from the essentially relativistic relation of explanation; and to analyze causation as explanation is to embrace a form of “causal idealism”, the view that causal connections are not among the objective features of the world. The paper closes with a brief discussion of the contrast between the two fundamentally opposed viewpoints about causality, namely causal idealism and causal realism.

This paper analyzes and evaluates quine's influential thesis that epistemology should become a chapter of empirical psychology. quine's main point, it is argued, is that normativity must be banished from epistemology and, more generally, philosophy. i claim that without a normative concept of justification, we lose the very concept of knowledge, and that belief ascription itself becomes impossible without a normative concept of rationality. further, the supervenience of concepts of epistemic appraisal shows that normative epistemology is indeed possible

The traditional view of science holds that science is essentially nomothetic—that is, the defining characteristic of science is that it seeks to discover and formulate laws for the phenomena in its domain, and that laws are required for explanation and prediction. This paper advances the thesis that there are no laws in the special sciences, sciences other than fundamental physics, and that this does not impugn their status as sciences. Toward this end, two arguments are presented. The first begins with Donald Davidson’s argument against psychophysical laws and develops a more perspicacious general argument against special science laws. The second is a generalized and more explicitly motivated argument based on J. J. C. Smart’s claim that biology, unlike physics, has no laws.

For three decades the writings of Jaegwon Kim have had a major influence in philosophy of mind and in metaphysics. Sixteen of his philosophical papers, together with several new postscripts, are collected in Kim [1993]. The publication of this collection prompts the present essay. After some preliminary remarks in the opening section, in Section 2 I will briefly describe Kim's philosophical 'big picture' about the relation between the mental and the physical. In Section 3 I will situate Kim's approach on the larger philosophical landscape, vis-à-vis various other approaches frequently discussed in contemporary philosophy of mind. This comparative discussion will further illuminate Kim's own position, and also will serve as groundwork for subsequent discussion. In Section 4 I will point out certain persistent internal tensions in Kim's philosophical position on the mind--body problem, tensions that emerge especially clearly against the backdrop of Section 3's comparative discussion of Kim's position relative to various competing positions. In the remainder of the paper I will focus on two issues at the heart of his position, with particular attention to what he says about them in some of the more recent papers and the postscripts in Kim [1993]. First, how should a materialist understand the notion that the mental is 'determined' by the physical? More specifically, what role, if any, should be played by the concept of supervenience in explicating this kind of determination relation? Kim's views on this matter have recently changed, and I will discuss the issue with particular attention to his own latest remarks on it. This is the business of Section 5. Second, need a viable materialism assert that mentalistic psychology is reducible to neurobiology? More specifically, should a materialist insist on reducibility, despite the currently influential line of argument used by non-reductive materialists, the 'multiple realization' argument? On this matter too, Kim's views have changed somewhat; again, I will discuss the issue with particular attention to his recent thinking. This is the business of Section 6.

Is social science ‘reducible’ to individual psychology, and ultimately to some physical theory? If a sociological theory, that is, a theory dealing with group phenomena, is ‘reduced’ in a relevant and appropriate sense to individual psychology, could we then say that the social phenomena in the domain of the sociological theory are just psychological phenomena of individuals? Conversely, if social events and processes are just individual psychological events and processes, then does it follow that any theory dealing with the former is ‘reducible’ to some theory dealing with the latter? Analogously, if psychological theory is ‘reducible’ to physical theory, say the neurological theory of the brain and the associated organs, could we say that psychological phenomena are just neurological phenomena in the brain? What of the converse of this question? Further, what is the bearing on these questions of the thesis that there are laws correlating types of social phenomena with types of individual psychological phenomena, or types of psychological phenomena with types of neurological phenomena?
