Sur la base de ce qu’il a appelé « le principe d’héritabilité causale », Jaegwon Kim a soutenu que les propriétés réalisables de façons multiples ne constituent pas des sortes causales scientifiques. Mon principal objectif est de répondre aux arguments de Kim contre le physicalisme non réductionniste. Je défends l’idée qu’il existe plus de pouvoirs causaux que les seuls pouvoirs causaux physiques. Cela n’a rien de surprenant puisqu’il existe plus de particuliers que le nombre total de particules physiques fondamentales. Et la réflexion sur la nature des individus, et plus spécifiquement sur leur capacité à préserver leur identité à travers le changement ou le remplacement de leurs parties, indique que les individus ont des pouvoirs causaux distincts de ceux des particuliers physiques qui les constituent. Je soutiens que si cela est plausible, alors l’abandon du principe d’héritabilité causale l’est tout autant.Jaegwon Kim has recently argued, using what he calls “The Causal Inheritance Principle”, that multiply realizable properties are not causal, scientific kinds. My primary concern is to reply to Kim's arguments against nonreductive physicalism. I shall defend the idea that there are, indeed, more causal powers than the physical. But this should come as no surprise, since there are more individuals than the total number of fundamental physical particles. Reflections on the nature of individuals, specifically, on their ability to survive through change or replacement of their parts, indicates that individuals have causal powers nonidentical with the causal powers of the physical individuals that constitute them. I claim that, if this is plausible, the rejection of The Causal Inheritance Principle is also plausible

Davidson argues that mental properties are causally relevant properties. I argue that Davidson cannot appeal to ceteris paribus causal laws to ensure that these properties are causally relevant, if he wishes to retain his argument for anomalous monism. Second, I argue that the appeal to supervenience cannot, by itself, give us an account of the causal relevancy of mental properties. I argue that, while mental properties may indeed 'make a difference' to the causally efficacious properties of events, this is not sufficient to show that mental properties are causally relevant

Kim's exclusion argument threatens to show that irreducible constituted objects are epiphenomenal. Kim's arguments are examined and found to be unconvincing; that a constituted cause requires its constituent to be a cause is not an adequate reason to reject the causation of the constituted object (event or property-instance). However, I introduce and argue for, the Causal Power Uniqueness Condition (CPUC). I argue that CPUC and the causal closure of the physical, implies that constituted objects or property-instances are not novel causal powers

This note criticizes Andrew Brennan's attempt to defend best?candidate theories of the identity of artefacts over time against certain now familiar objections. Adoption of a mereological conception of individuals does not, in itself, provide the means for a satisfactory response to objections of Wiggins and Noonan (some of which are anyway ill?focused). The way forward consists in recognizing that the consequences of best?candidate theories which have been thought objectionable (in particular, commitment to the extrinsicness of identity) do not violate the necessity of identity and imply ? what anyway ought to seem unexceptionable ? that a predicate such as ?constituting the ship which is the Ship of Theseus? does not denote a genuine property of the hunk of matter of which the predicate is true. Once these consequences have been clearly mapped out, the best?candidate theorist's commitment to the extrinsicness of identity does not appear absurd

The thesis that there can be vague objects is the thesis that there can be identity statements which are indeterminate in truth-value (i.e., neither true nor false) as a result of vagueness (as opposed, e.g., to reference-failure), "the singular terms of which do not have their references fixed by vague descriptive means". (if this is "not" what is meant by the thesis that there can be vague objects, it is not clear what "is" meant by it.) the possibility of vague objects should not be taken, in itself, to imply the more radical thesis that the identity relation can be one of "degree". one can hold that the concept of degrees of identity is absurd (how can one thing be more or less identical to another?) "and" that indeterminacy in identity is possible; hence, any incoherence in the idea of degrees of identity does not thereby undermine the idea of indeterminate identity

In this discussion paper, I evaluate some arguments of Mark Johnston's which appear in his articles «Fission and the Facts» and «Reasons and Reductionism» . My primary concern is with his description of fission cases, and his assessment of the implications of such cases for value theory. In particular, Johnston advances the following three claims:Rejecting the intrinsicness of identity is an arbitrary response to the paradox of fission;Fission cases involve indeterminate identity;Contra Parfit, fission cases have no implications for value theory in the actual world.I argue that and are false, and that , if true, is not true for any reason that Johnston gives

Why is there something rather than nothing? Does God exist? Does time flow? What are we? Do we have free will? What is truth? Metaphysics is concerned with ourselves and reality, and the most fundamental questions regarding existence. This clear and accessible introduction covers the central topics in metaphysics in a concise but comprehensive way. Brian Garrett discusses the crucial concepts in a highly readable manner, easing the reader in with a look at some important philosophical problems. He addresses key areas of metaphysics: God Existence Modality Universals and particulars Facts Paradoxes of material constitution Causation Time Free will Personal identity Truth. This second edition has been thoroughly revised. Most chapters include substantial amounts of new material, and there are additional chapters on Existence, Modality, Facts and Paradoxes of Material Constitution. _What is this thing called Metaphysics?_ contains many helpful student-friendly features. Each chapter concludes with a useful summary of the main ideas discussed, a glossary of important terms, study questions, annotated further reading, and a guide to web resources. Text boxes provide bite-sized summaries of key concepts and major philosophers, and clear and interesting examples are used throughout.
