To determine whether dispositions are causally relevant, we have to get clear about what causal relevance is. Several characteristics of causal relevance have been suggested, including Explanatory Power, Counterfactual Dependence, Lawfullness, Exclusion, Independence, and Minimal Sufficiency. Different accounts will yield different answers about the causal relevance of dispositions. However, accounts of causal relevance that are the most plausible, for independent reasons, render the verdict that dispositions are causally relevant.

Grounding theorists insist that grounding and explanation are intimately related. This claim could be understood as saying either that grounding ‘inherits’ its properties from explanation or it could be interpreted as saying that grounding plays an important—possibly an indispensable—role in metaphysical explanation. Or both. I argue that saying that grounding ‘inherits’ its properties from explanation can only be justified if grounding is explanatory by nature, but that this view is untenable. We ought therefore to be ‘separatists’ and view grounding and (...) explanation as distinct. As it turns out, though, once grounding has been in this sense distinguished from the explanation it backs, the view that the role grounding plays in explanation justifies its introduction ends up in serious trouble. I conclude that the role grounding plays in explanation does not justify attributing to grounding whatever nature we think it has, and it most likely does not give us any special reason to think grounding exists.

I argue that (strong) psychophysical supervenience, properly understood as a metaphysical dependence or determination relation, helps to account for the causal/explanatory relevance of mental properties because (1) it blocks a standard epiphenomenalist objection to the effect that an event's mental properties are 'screened off' by their physical properties: (2) it accounts for the _causal (and not merely _normative or merely _nomological) status of commonsense psychological generalizations; (3) it accounts for the _nonredundancy and _irreducibility of psychological explanations.

The aim of this paper is to defend a version of nonreductive materialism against the epiphenomenalist objection to which Davidson's anomalous monism has often been held to be vulnerable. After considering a number of options for dealing with the objection, I argue that an appeal to the notion of strong supervenience (properly explicated) can both rebut a common form of the "property" ("type") epiphenomenalist objection and provide a grounding for the causal relevance ("efficacy") of mental properties.

The aim of this paper is to show that Kim’s ‚supervenience argument’ is at best inconclusive and so fails to provide an adequate challenge to nonreductive physicalism. I shall argue, first, that Kim’s argument rests on assumptions that the nonreductive physicalist is entitled to regard as question-begging; second, that even if those assumptions are granted, it is not clear that irreducible mental causes fail to␣satisfy them; and, third, that since the argument has the overall structure of a reductio, which of (...) its various premises one performs the reductio on remains open to debate in an interesting way. I shall finally suggest that the issue of reductive vs. nonreductive physicalism is best contested not in the arena of mental causation but in that in which the issues pertaining to theory and property reduction are currently being debated.

Drawing on material from Husserlian phenomenology, we can reconstruct a realist version of anomalous monism (rAM). According to such a view, mental events are identical to some physical events because they simultaneously exemplify mental and physical properties. rAM would have to confront the charge of epiphenomenalism because Husserl rejects psychophysical causal interaction. And as a form of nonreductive physicalism, rAM also faces the challenge of Kim’s supervenience argument and explanatory exclusion. Utilizing Husserl’s conception of mental motivation and contemporary elaborations of (...) substance causation, rAM can refute the accusation of epiphenomenalism and overcome the problem of exclusion.

In this response to David Bradnick's and Bradford McCall's defense of Amos Yong's usage of emergence theory, we defend our previous argument regarding the tension between Yong's Pentecostal commitments and the philosophical entailments of emergence theory. We clarify and extend our previous concerns in three ways. First, we explore the difficulties of construing divine action naturalistically. Second, we clarify the problems of employing supervenience in theology. Third, we show why Bradnick's and McCall's advice to Yong to adopt weak emergence is (...) theologically costly. In conclusion, it is suggested that theologians within the science and religion dialogue should not fear, but recover, the language of supernaturalism and dualism. (shrink)

This article critically analyzes Owen Flanagan's physicalism and attempt at deriving ethical normativity from current neuroscience. It is argued that neurophysicalism, despite Flanagan's harsh critique of “the new mysterians,” entails a form of mysterianism and that it fails to appropriately ground human mentality within physicalism. Flanagan seeks to bring spirituality and a physicalist ontology together by showing how it is possible to derive an account of the good life from science. This attempt is critiqued and it is shown that Flanagan (...) fails to establish the consistency between ethical normativity and physicalism. Hence, another form of mysterianism seems to emerge within this normative mind science. (shrink)

This paper tries to remove some obstacles standing in the way of considering mental properties as both genuine natural kinds and causally efficacious rather than epiphenomena. As the case of temperature shows, it is not justified to conclude from a property being multiply realizable to it being irreducible. Yet Kim's argument to the effect that if a property is multiply realizable with a heterogeneous reduction base then it cannot be a natural kind and possesses only derivative “epiphenomenal” causal efficacy is (...) not conclusive either. The fact that temperature is, but jade is not, a natural kind cannot be established by comparing the heterogeneity of their respective reduction bases, but rather by the fact that the former is and the latter is not embedded in laws of nature.

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

Dual-attribute theories are alleged to face a problem with mental causation which commits them to either epiphenomenalism or overdetermination – neither of which is attractive. The problem, however, is predicated on assumptions about psychophysical relations that dual-attribute theorists are not obliged to accept. I explore one way they can solve the problem by rejecting those assumptions.

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 (and ultimately to physics)? 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)

This paper argues that the normative character of our unreflective situated behaviour is not factual. We highlight a problematic assumption shared by the two most influential trends in contemporary philosophy of cognitive science, reductionism and enactivism. Our intentional, normative explanations are referential, descriptive or factual. Underneath this assumption lies the idea that only facts can make true or false our attributions of cognitive, mental and agential abilities. We will argue against this view by describing the main features and problems of (...) reductionism and enactivism and then we will offer two arguments against this shared factualist assumption: (1) normative vocabulary is ineliminable if we want a complete explanation of our situated practices; and (2) the factualist assumption is a species of the is-ought fallacy. Finally, we will claim that a folk psychological explanation of our normative practices is fully compatible with ontological naturalism when such descriptivist or factualist assumption is rejected.

By a macro-level feature, I understand any feature that supervenes on, and is thus realized in, lower-level features. Recent discussions by Kim have suggested that such features cannot be causally relevant insofar as they are not classically reducible to lower-level features. This seems to render macro-level features causally irrelevant. I defend the causal relevance of some such features. Such features have been thought causally relevant in many examples that have underpinned philosophical work on causality. Additionally, in certain typical biological cases, (...) we conceive of causally relevant features at various compatible levels of analysis. When elaborated, these points make a strong prima facie case for macro-level causal relevance. However, we might abandon both the philosophical guideposts and the corresponding explanatory practice in the special sciences were we convinced that no reflective philosophical account could provide for the causal relevance there supposed. I show that such drastic measures are not necessary, for we can make sense of macro-level causal relevance by drawing on Paul Humphreys' recent work in ways suggested by the concrete examples considered here.

The object of this paper is to discuss several issues raised by Fred Dretske’s account of the causal efficacy of content, as given in his book Explaining Behavior. To warrant the causal efficacy of folk-psychological properties while keeping attached to a naturalistic framework, Fred Dretske proposes that these properties are causes of a peculiar type, what he calls structuring causes. Structuring causes are not postulated ad hoc, to somehow account for the causal efficacy of content. Dretske claims that we independently (...) need this dualism of causes to make sense of some of our (not necessarily involving mental states) causal explanations. Even if this variety of dualism is not untenable from a openly-minded physicalistic viewpoint, it seems for several reasons preferable to establish that content properties are causally efficacious in the same sense that physical properties are. The main point I will try to make in this paper is a metaphysical one, namely, that Drestke’s structuring causes are causes of a more ordinary kind. I will try to show that we can make sense of the phenomena that structuring causes are introduced to account for in more conservative terms, having only recourse to the material we must anyway posit to understand ordinary causal explanations.

Brute facts are facts that have no explanation. If we come to know that a fact is brute, we obviously don’t get an explanation of that fact. Nevertheless, we do make some sort of epistemic gain. In this essay, I give an account of that epistemic gain, and suggest that the idea of brute facts allows us to distinguish between the notion of explanation and the notion of understanding. I also discuss Eric Barnes’ (1994) attack on Friedman’s (1974) version of (...) the uni-fication theory of explanation. The nification theory asserts that scientific understanding results from minimizing the number of brute facts that we have to accept in our view of he world. Barnes claims that the unification theory cannot do justice to he notion of being a brute fact, because it implies that brute facts are gaps in our understanding of the world. I defend Friedman’s theory against Barnes’ critique. (shrink)

Author's note: This is a piece from the very early stage of my career. Please regard it as a historical document.

I survey the philosophical literature on grounding explanation and its connection to metaphysical ground.

This chapter aims to explore the intersection of Christian theism, a neo-Aristotelian gloss on metaphysical grounding, and creaturely participation in God. In section one, I aim to de- velop several core tenets at the heart of a theistic participatory ontology as it is found in the Christian tradition, what I call minimal participatory ontology. In section two, I examine the contemporary notion of metaphysical grounding, namely the formal and structure features of the grounding relation, and offer a grounding-theoretic framework for (...) understanding a mini- mal participatory ontology. Finally, in section three, I put forward a neo-Aristotelian account of metaphysical grounding in particular, one that is uniquely suited to capture the central tenets of minimal participatory ontology.

In a series of recent papers, Cynthia MacDonald and Graham MacDonald offer a resolution to the twin problems of mental causation and mental causal relevance. They argue that the problem of mental causation is soluble via token monism – mental events are causally efficacious physical events. At the same time, the problem of mental causal relevance is solved by combining this causally efficacious mental property instance with the systematic co-variation between distinct mental properties of the cause and the action-theoretic properties (...) of the effect in question. In this paper we argue that the solution offered by Mac- Donald and MacDonald faces significant difficulties in resolving both of the twin problems of mental causation and mental causal relevance.

Turri argues against what he calls an “orthodox” view of the relationship between propositional and doxastic justification, according to which (Basis) it is sufficient for S to be doxastically justified in believing p that p is propositionally justified for S in virtue of having reason(s) R and S believes p on the basis of R. According to Turri, (Basis) is false and hence the orthodox view is wrong. Turri offers “an alternative proposal,” the definitive thesis of which is that the (...) subject’s intellectual abilities explain why a given proposition, p, is justified for her, and argues that, contra the orthodoxy, this proposal leads to explaining propositional justification in terms of doxastic justification rather than vice versa. In this paper, I argue for the following claims: (i) There are good reasons to think that Turri misidentifies “the orthodox view” and his objection thereby misfires, (ii) Even if we assume that Turri’s identification of the orthodox view is correct, his counter-examples to that view are far from being decisive, and (iii) Turri’s own proposal is not “an alternative” to the orthodox view but can be accommodated by it.

This dissertation is a defence of metaphysical ethical naturalism according to which there is a moral reality which is part of the natural world. The implication of this view is that moral properties, such as moral goodness, justice, compassion and so forth are part of the natural world, and inquiries concerning these moral entities are conducted in similar empirical ways of reasoning to that in which scientific inquiries are conducted. I defend metaphysical ethical naturalism by a variety of explanationist argument (...) in the tradition of Cornell realism. I examine preceding proposals for this argument, and focus on one version of it, which I call ‘the abductive argument for moral realism’. Although there was a suggestion about the abductive argument, the argument has not been discussed enough in the literature. This dissertation is a defence and discussion about the abductive argument which has not been properly examined. The defence of the argument requires the examination of how first-order ethical theory can be developed in the similar empirical ways scientific theories are developed. This will be an attempt to show the analogy between scientific inquiries and ethical inquiries. Describing the analogy between science and ethics, I will argue that the analogy can be best explained in terms of the approximate truth of normative theory which implies the existence of mind-independent natural moral properties.

This article aims to vindicate the commonsensical view that what we think affects what we do. In order to show that mental properties like believing, desiring and intending are causally explanatory, I propose a nonreductive, materialistic account that identifies beliefs and desires by their content, and that shows how differences in the contents of beliefs and desires can make causal differences in what we do.
