Global supervenience of beliefs about physical states of affairs on such states has strongly counter-intuitive consequences about what beliefs we can nomologically hold. Tfcs is an argument against a global supervenience of all mental properties on physical 0 n es, and, since that is implied by strong supervenience, also against that as the preferred materialist thesis.

THIS PAPER ARGUES THAT GLOBAL SUPERVENIENCE IS NOT\nEQUIVALENT TO KIM'S STRONG SUPERVENIENCE (AS HE HAS ARGUED\nIT IS) AND THAT IT DOES NOT ENTAIL THE TYPE OR TOKEN\nREDUCIBILITY OF THE SUPERVENIENT PROPERTIES TO THE\nPROPERTIES UPON WHICH THEY SUPERVENE (AS STRONG\nSUPERVENIENCE DOES). IT THEN TURNS TO AN EXAMINATION OF THE\nARGUMENT THAT GLOBAL SUPERVENIENCE IS EQUIVALENT TO\nIMPLICIT DEFINABILITY WHICH ACCORDING TO BETH'S THEOREM\nENTAILS EXPLICIT DEFINABILITY. THE AUTHOR HOPES TO SHOW\nTHAT GLOBAL SUPERVENIENCE IS A DISTINCT AND ESPECIALLY\nINTERESTING RELATION WHICH CAPTURES (...) ASPECTS OF THE\nRELATIONSHIP BETWEEN PHYSICAL PROPERTIES AND THOSE\nPROPERTIES WHICH ARE DETERMINED BY THEM THAT OTHER\nRELATIONS DO NOT DO JUSTICE TO. (shrink)

The topic under examination is the idea of ‘supervenient dualism’, which Christopher Shields first put forward in his study of Aristotle's theory of psychology. Shields takes supervenient dualism to be a form of ‘substance supervenience’, in which an immaterial substance supervenes upon a material or physical substance. Shields, however, does not develop a convincing version of supervenient dualism because he fails to develop a convincing version of substance supervenience. A plausible version of substance supervenience can be developed (...) in the light of Jaegwon Kim's idea of ‘multiple‐domain supervenience’, although this version of substance supervenience is not able to provide the basis for an adequate formulation of supervenient dualism. The nature of this version of substance supervenience depends upon a relation of coordination between the substances, and there does not seem to be any relation of coordination that yields a form of substance supervenience that also counts as a form of supervenient dualism.

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)

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. (shrink)

Supervenience is one of the 'hot discoveries' of analytic philosophy, and this collection of essays on the topic represents an examination of it and its application to major areas of philosophy. The interest in supervenience has much to do with the flexibility of the concept. To say that x supervenes on y indicates a degree of dependence without committing one to the view that x can be reduced to y. Thus supervenience is a relationship that has the (...) potential of replacing the traditional notion of dependence, while performing at least part of the function reductive relationships were supposed to fulfil. Moreover, since it is a topic-neutral concept, supervenience has a wide range of applicability. (shrink)

This paper surveys some ways in which the chemical realm can be described and outlined in terms of the concept of supervenience. The particular contours of general chemical theory provide a ready basis for interpretation of determination, covariance, and nonreduction—the characteristic metaphysical facets of the supervenience relation—in mutual terms. Building on this, the extent to which chemically characterized properties and entities can be described in terms of a supervenience-scaffolded structure represents a particularly vivid application that philosophers in (...) general interested in supervenience would do well to attend to. In addition, the model of chemical supervenience given here can be used as a rubric on which to decide on issues already raised by philosophers of chemistry. (shrink)

In the first section of this paper, I articulate Jaegwon Kim's argument against emergent down ward causation. In the second section, I canvas four responses to Kim's argument and argue that each fails. In the third section, I show that emergent downward causation does not, contra Kim, entail overdetermination. I argue that supervenience of emergent upon base properties is not sufficient for nomological causal relationsbetween emergent and base properties. What sustains Kim's argument is rather the claim that emergent properties (...) realized by base properties can have no causal powers distinct from those base properties. I argue that this is false.

Many have felt that it is impossible to defend autonomous laws of social science: where the regularities upheld are law-like it is argued that they are not at base social scientific, and where the phenomena to be explained would seem to require social descriptions, it is argued that laws governing the phenomena are unavailable at that level. But is it possible to develop an ontology that supports the dependence of the social on the physical, while nonetheless supporting the explanatory power (...) of genuinely autonomous social scientific laws? The aim of this paper is to show that reductive explanation is not a requirement of a `naturalist' ontology, thereby defending an account of supervenience as a suitable framework within which to recognize a metaphysical relationship between the natural and the social that is consistent with the pursuit of autonomous nomological social scientific explanations.

It seems that higher-level, nonbasic properties can only manifest their causal powers by exerting causal influence on lower-level, physically basic phenomena in the first place. A very influential line of reasoning conceives of this form of downward causation as either reducible to causation by physical properties or as ultimately untenable, because incompatible with the causal closure of physical reality. The paper argues that this is not so. It examines, first, why it is that a recent attempt by Noordhof to substantiate (...) the notion of supervenient causation in a nonreductive framework fails. The upshot of this examination is the claim that any attempted specification of the most basic causal factors which supposedly underlie a causal transaction cannot account for the counterfactually necessary connections with the effect in question. By contrast, the specification of these factors at a higher level would allow establishing such connections. The paper closes with a discussion of how this view of autonomous causation at the higher-level can coexist with the notion of a complete specification of the causes of any physical effect exclusively in physical terms.

The International Research library of Philosophy collects in book form a wide range of important and influential essays in philosophy, drawn predominantly from English language journals. Each volume in the library deals with a field of enquiry which has received significant attention in philosophy in the last 25 years and is edited by a philosopher noted in that field.

It is often argued that if a mentalproperty supervenes on a physical property, then (1)the mental property M ``inherits'''' its causal efficacyfrom the physical property P and (2) the causalefficacy of M reduces to that of P. However, once weunderstand the supervenience thesis and the concept ofcausation probabilistically, it turns out that we caninfer the causal efficacy of M from that of P andvice versa if and only if a certain condition, whichI call the ``line-up'''' thesis, holds. I argue (...) that thesupervenience thesis entails neither this conditionnor its denial. I also argue that even when theline-up thesis holds true, reductionism about thecausal efficacy of the mental property doesn''tfollow. (shrink)

The concept of supervenience is highly important in the philosophy of psychology as a tool to elucidate the relationship between mind and body. it is a widely accepted view that mental properties (states, events) are supervenient over the physical; there is no mental difference without a physical difference. the aim of this paper is to explain what supervenience is, its significance and application in various fields of philosophy, to examine several definitions of supervenience, and finally, to define (...) its four basic forms.

A field‐oriented interpretation of Whiteheadian societies of actual occasions, when used to explain the notion of “strong supervenience” as applied to the mind‐brain problem, allows one to claim that not only higher‐level properties such as consciousness but even higher‐level entities such as the mind or soul are emergent from lower‐level systems of neuronal interaction. Moreover, it also explains the preexistence of God to the world and Christian belief in eternal life with the triune God in a way that is (...) impossible within the limits of a theory of strong supervenience.

Blackburn argues that moral supervenience in conjunction with the lack of entailments from naturalistic to moral judgments poses a challenge to moral realism. Klagge and McFetridge try to avert the challenge by appealing to synthetically necessary connections between natural and moral properties. Blackburn rejoins that, even if there are such connections, the challenge still remains. We remain agnostic on the question whether there are such connections, but argue against Blackburn that, if there are indeed such connections, then the challenge (...) to moral realism, properly phrased, does not hold up.

This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

Some recent work in the philosophy of quantum mechanics has suggested that quantum systems can be thought of as non-separable and therefore non-individual, in some sense, in Bell and E.P.R. type situations. This suggestion is set in the context of previous work regarding the individuality of quantal particles and it is argued that such entities can be considered as individuals if their non-classical statistical correlations are understood in terms of non-supervenient relations holding between them. We conclude that such relations are (...) strongly non-supervenient in Cleland's sense and note a possible connection between this idea and the realist quantum logic programme. (shrink)

After some preliminary clarifications, arguments for the supposed asymmetry of supervenience and determination, such as they are, are shown to be unsound. An argument against the supposed asymmetry is then constructed and defended against objections. This is followed by explanations of why the intuition of asymmetry is nonetheless so entrenched, and of how the asymmetric ontological priority of the physical over the non-physical can be understood without the supposed asymmetry of supervenience and determination.

One aim philosophers have in constructing moral theories is to identify the natural or non-Moral characteristics that make actions right or obligatory, Things good, Or persons virtuous. Yet we have no clear understanding of what it is for certain of a thing's non-Moral properties to be responsible for its moral properties. Given the recent interest in the concept of supervenience one might think that the dependence of moral on natural properties could be explained in terms of it. Unfortunately, None (...) of the definitions of supervenience offered so far is adequate to this task, And indeed, There is some reason to think that this dependence relation is ultimately mysterious.

Expressivists traditionally explain normative supervenience by saying it is a conceptual truth. I argue against this tradition in two steps. First, I show the modal claim that stands in need of explanation has been stated imprecisely. Classic arguments in metaethics for normative supervenience and those that rely on it as a premise presuppose a constraint on the supervenience base that is rarely (if ever) made explicit: the repeatability of the non-normative properties on which the normative supervenes. Non-normative (...) properties are repeatable when it is possible for numerically distinct individuals to share them. Second, I show if the modal truth that stands in need of explanation entails that there are individuals exactly alike in repeatable non-normative respects that cannot normatively differ, then standard expressivist accounts of normative supervenience as a conceptual truth are unsuccessful. Expressivist metasemantics for normative terms, together with constitutive facts about the non-cognitive attitudes essentially involved in normative thought, strongly suggest that repeatable supervenience could not be a conceptual truth. I argue, finally, that although repeatable supervenience bears the marks of a conceptual truth, expressivists should be content to treat it as an ordinary normative truth, and to explain it the same way they explain other normative truths.

The paper aims at meeting Blackburn’s challenge to explain the non-reductive supervenience of moral predicates on natural ones. It offers a critical examination of Hare’s model of moral thinking which can be used as a candidate for such an explanation.

Yet some revisions of the model are suggested, and it is claimed that the improved version does supply the required explanation. The model suggested in the (...) paper carries a meta-ethical implication concerning the superiority of the anti-realist understanding of moral discourse. (shrink)

Available from UMI in association with The British Library. Requires signed TDF. ;This thesis defends the claim that the principle of methodological solipsism can play no role in the formation of the theories of cognitive psychology. Corresponding to this negative claim, but assuming a comparatively minor role, will be the positive claim that a scientific psychology ought to deal in explanations which relate mental states in virtue of their semantic contents. ;The basis of the case against methodological solipsism is the (...) claim that the explanatory properties invoked by this principle are individuation dependent on properties of semantic content. In Chapter I the idea of methodological solipsism will be discussed, and two forms distinguished. One of the versions of methodological solipsism identified invokes the explanatory notion of the narrow content of a mental state. The other version invokes the notion of formal or syntactic properties possessed by mental states. In both cases it will be argued that these properties can be identified only by way of the semantic contents of their associated mental states. The notion of narrow content will be discussed in Chapter II. The case against that version of methodological solipsism which invokes syntactic properties will be constructed in Chapters III-V. The latter argument constitutes the bulk of the thesis, and derives from considerations centred around the principles of anomalism, supervenience, and the relation between them. These arguments are intended to be of independent interest as solutions to certain persistent problems in the philosophy of mind. (shrink)

An attempt is first made to clarify why Stephen Schiffer may legitimately claim that his noncompositional account of meaning differs from other non-compositional semantic doctrines such as the hidden-indexical theory of propositional attitudes. Subsequently, however, doubt is cast upon Schiffer's main contention that, as far as language of thought is concerned, a compositional supervenience theory can adequately satisfy all the desiderata a compositional meaning theory is traditionally called upon for. This doubt basically depends on the fact that, once a (...) physical property is assigned by the compositional supervenience theory to the relevant nominal constituent of a Mentalese attitude report as the basic element on which the physical property assigned to the whole report depends, such a property precisely plays the role of a mode of presentation of the referent of that constituent. Finally, the following dilemma is arisen: in order to account for the meaning of attitude reports either the dismissal of modes of presentation or the rejection of compositionality is to be given up.

The claim that the having of aesthetic properties supervenes on the having of non-aesthetic properties has been widely discussed and, in various ways, defended. In this paper, I will show that even if it is sometimes true that a supervenience relation holds between aesthetic properties and the 'subvenient' non-aesthetic ones, it is not the interesting relation in the neighbourhood. As we shall see, a richer, asymmetric and irreflexive relation is required, and I shall defend the claim that the more-and-more-popular (...) relation of grounding does a much better job than supervenience.

Supervenient libertarianism maintains that indeterminism may exist at a supervening agency level, consistent with determinism at a subvening physical level. It seems as if this approach has the potential to break the longstanding deadlock in the free will debate, since it concedes to the traditional incompatibilist that agents can only do otherwise if they can do so in their actual circumstances, holding the past and the laws constant, while nonetheless arguing that this ability is compatible with physical determinism. However, we (...) argue that supervenient libertarianism faces some serious problems, and that it fails to break us free from this deadlock within the free will debate. (shrink)

In the 1970s and 1980s, Simon Blackburn published a number of much-discussed works in which he argued that the supervenience of the moral on the natural generates a serious problem for moral realism, a problem which his own brand of moral projectivism can avoid. As we will see below, Blackburn construed moral supervenience in terms of what is known as weak supervenience. Partly in response to Blackburn, a number of philosophers have argued that weak supervenience is (...) too weak to capture the intuitive sense in which the moral supervenes on the natural. Instead, it is argued, we should opt for strong supervenience, and, further, that strong supervenience completely disables Blackburn's argument against moral realism. This idea – that strong supervenience undermines Blackburn's argument – is very common in recent metaethics, and the purpose of the present paper is to develop a challenge to this near-orthodoxy.

In his Groundwork of the Metaphysics of Morals, Kant’s desiderata for a supreme principle of practical reasoning and morality require that the subjective conditions under which some action is thought of as justified via some maxim be sufficient for judging the same action as justified by any agent in those conditions. This describes the kind of universalization conditions now known as moral supervenience. But when he specifies his “formula of universal law” (FUL) Kant replaces this condition with a quite (...) different kind of universality: the judgment that some agent could rationally (i.e., without willing the frustration of his own valued ends) will his adoption of some maxim under the condition that this would cause all agents in his world to adopt it as well. Our wills typically lack this efficacy, so requiring that our wills conform to what would be rational for a hypothetical agent in this situation to will is a heteronomous requirement. Several intuitively wrong maxims pass Kant’s test but fail the test of supervenience, because they generate no contradiction in a world of universal compliance but do so in non-ideal worlds, demonstrating the inadequacy of the FUL and the logical superiority of moral supervenience. -/- NOTE: in the published version of this article's title, "became" is mistakenly, and ungrammatically, replaced with "become.".

Humean supervenience is the conjunction of three theses: Truth supervenes on being, Anti‐haecceitism, and Spatiotemporalism. The first clause is a core part of Lewis's metaphysics. The second clause is related to Lewis's counterpart theory. The third clause says there are no fundamental relations beyond the spatiotemporal, or fundamental properties of extended objects. Supervenience is classified into strong modal Humean supervenience, local modal Humean supervenience and familiar modal Humean supervenience which states that: for any two "worlds (...) like ours", if the spatiotemporal distribution of fundamental qualities is the same at each world, the contingent facts are also the same. The fact that quantum mechanics raises problems for Humean supervenience does not undercut the philosophical significance of Lewis's defense of Humean supervenience. Humean supervenience says that in a world like ours, the fundamental properties are local qualities: perfectly natural intrinsic properties of points, or of point‐sized occupants of points. (shrink)

My primary goal in this paper is to focus attention on a certain conception of internal access, on the Cartesian conception that a rational subject's capacity to determine sameness and difference in explicit propositional attitudes is independent of knowledge of the external world. This conception of introspection plays a crucial, if unacknowledged, role in numerous arguments and theoretical positions. In particular, it plays a large role in motivating psychological internalism. I argue in favor of rejecting this epistemology and the internalism (...) it supports. (shrink)

Developing and motivating the notion of supervenience. Investigating the relationship to reducibility and definability (equivalence, under certain conditions), and to microphysical determination.

In a number of articles Donald Davidson has argued that the charitable nature of his method of radical interpretation rules out the possibility of massive error and thus refutes Cartesian skepticism. The diversity of such arguments and the suggestions that are all being made under the name of the principle of charity have prompted a large body of conflicting responses, adding only to the obscurity of the issues that are generally associated with the question of skepticism. In this paper I (...) propose to consider the debate in a new light by reconstruing the principle of charity as a supervenience constraint on belief attribution. This would help explain some of the puzzling features of Davidson's arguments, like the idea of an omniscient interpreter, and the ensuing commentaries. Having provided an analysis of the limitations of Davidson's arguments, I shall then suggest an alternative explanation of the purported necessity of the principle of charity. Finally, having construed the principle of charity as a supervenience constraint, I shall examine what consequences this construal has for the logical status of the principle itself and its alleged epistemic potentials.

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley (...) driver is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false. (shrink)

The existence and importance of supervenience principles for identity across times and worlds have been noted, but insufficient attention has been paid to their precise nature. Such attention is repaid with philosophical dividends. The issues in the formulation of the supervenience principles are two. The first involves the relevant variety of supervenience: that variety is global, but there are in fact two versions of global supervenience that must be distinguished. The second involves the subject matter: the (...) names “identity over time” and “identity across worlds” are misnomers, for in neither case is identity at issue. The philosophical dividends then follow. Nathan Salmon’s argument that identity over time needs no “grounds” in matters of qualitative fact can be answered, as can an argument offered by many, that coincident objects would require objectionably ungrounded differences in identities across times and worlds.

Jaegwon Kim is one of the most preeminent and most influential contributors to the philosophy of mind and metaphysics. This collection of essays presents the core of his work on supervenience and mind with two sets of postscripts especially written for the book. The essays focus on such issues as the nature of causation and events, what dependency relations other than causal relations connect facts and events, the analysis of supervenience, and the mind-body problem. A central problem in (...) the philosophy of mind is the problem of explaining how the mind can causally influence bodily processes. Professor Kim explores this problem in detail, criticizes the nonreductionist solution of it, and offers a modified reductionist solution of his own. Both professional philosophers and their graduate students will find this an invaluable collection. (shrink)

An encyclopedic article on epistemic supervenience in Blackwell companion to epistemology, 2 ed.

This paper is concerned with the notions of supervenience and mechanistic constitution as they have been discussed in the philosophy of neuroscience. Since both notions essentially involve specific dependence and determination relations among properties and sets of properties, the question arises whether the notions are systematically connected and how they connect to science. In a first step, some definitions of supervenience and mechanistic constitution are presented and tested for logical independence. Afterwards, certain assumptions fundamental to neuroscientific inquiry are (...) made explicit in order to show that the presented definitions of supervenience are virtually uninteresting for theory construction in this field. In a third step, a new formulation of supervenience is developed that makes explicit reference to the notion of constitution and that bridges the gap between the philosophical concepts and explanatory practice in neuroscience.

Global supervenience of beliefs about physical states of affairs on such states has strongly counter-intuitive consequences about what beliefs we can nomologically hold. This is an argument against a global supervenience of all mental properties on physical ones, and, since that is implied by strong supervenience, also against that as the preferred materialist thesis.

Neil Campbell has argued that certain problems with the doctrine of psycho-physical supervenience can be overcome if supervenience is viewed as a relation between predicates rather than as a relation between properties. Campbell suggests that, when properly understood, this predicate version of supervenience "expresses a form of psycho-physical dependence that might be useful to those who wish to argue for a supervenience-based physicalism”. In this note I indicate why I think we ought to resist this suggestion. (...) First, I argue quite generally that any appeal to a distinction between predicates and properties is irrelevant to issues concerning physicalism and supervenience. And, second, I argue that Campbell's own predicate version of supervenience fails to capture a notion of dependence that physicalists are likely to find useful. I conclude that viewing supervenience as a relation between predicates does not help in articulating a more plausible version of physicalism. (shrink)

Physicalism is standardly construed as a form of monism, on which all concrete phenomena fall under one fundamental type. It is natural to think that monism, and therefore physicalism, is committed to a supervenience claim. Monism is true only if all phenomena supervene on a certain fundamental type of phenomena. Physicalism, as a form of monism, specifies that these fundamental phenomena are physical. But some argue that physicalism might be true even if the world is disorderly, i.e., not ordered (...) by supervenience relations in the way commonly supposed (Montero in J Philos 110:92–110, 2013; Leuenberger in Inquiry 57:151–174, 2014; Montero and Brown in Topoi 37(3):523–532, 2018; Zhong in Philos Stud 178(5):1529–1544, 2021). Unless these authors intend to challenge the claim that physicalism is a type of monism—a claim so central to the dialectic in philosophy of mind that rejecting it risks changing the subject—they are committed to challenging a supervenience requirement for monism. We argue that monism entails that there are substantial supervenience relations among concrete phenomena: relations that would not obtain in a disorderly world. Our argument thus has implications for debates about physicalism and supervenience, and sheds light on an under-discussed issue: what is implied by classifying a theory in the philosophy of mind as a form of monism? We also argue that physicalism’s commitment to monism creates problems for _via negativa_ physicalism, on which the physical is characterized negatively. (shrink)
