How did I raise my arm? The simple answer is that I raised it as a consequence of intending to raise it. A slightly more complicated response would mention the absence of any factors which would inhibit the execution of the intention- and a more complicated one still would specify the intention in terms of a goal (say, drinking a beer) which requires arm-raising as a means towards that end. Whatever the complications, the simple answer appears to be on the (...) right track. (shrink)

Defines physicalism in terms of claims that microphysical entities constitute everything and that microphysical laws govern everything. With a reply by Crane.

I shall argue in this article that there are certain objectual and methodological boundaries imposed by the nature of physics that all formulations of physicalism based on physical theories should respect. Therefore, empirical physicalism – i.e., the sort of physicalism that is eager to accept all the entities included in some future, ideal and complete physical theory and all entities dependent on them (see Jeffrey Poland and Janice Dowell) – is already committed to the exclusion of certain sorts of entities (...) from its ontological inventory and it is far less tolerant than one might expect. After having presented my argument, I shall describe four plausible boundaries to what can be studied by physics. The boundaries will contribute to constructing a new version of physicalism, i.e., physics physicalism, whose acceptance is entailed by the acceptance of empirical physicalism. Finally, I shall briefly deal with three objections against my strategy and I shall evaluate the consequences of the acceptance of my conclusions for both physicalists and non-physicalists. (shrink)

The thesis explores and suggests a solution to a problem that I identify in John McDowell’s and Lynne Rudder Baker’s approaches to mental and intention-dependent (ID) causation in the physical world. I begin (chapter 1) with a brief discussion of McDowell’s non-reductive and anti-scientistic account of mind and world, which I believe offers, through its vision of the unbounded conceptual and the world as within the space of reasons, to liberate and renew philosophy. However, I find an inconsistency in McDowell’s (...) criticism of Davidson’s anomalous monism (chapter 2), stemming from a tension between McDowell’s naïve common sense view of mental causation and an understanding of ordinary physical causation which I think McDowell ought to embrace, which portrays it as both objective, in the sense of being recognition- independent, and as belonging within the space of reasons. The question of the relation between these two concepts of causation is an aspect of the more general question of the relation between the space of reasons and the realm of law. In chapter 3 I begin examining the possibility that Baker’s account of material and property constitution could form the basis of a bridge between the two spaces, and find it generally promising. However, I find that her defence of her version of non-reductive monism against Kim’s causal arguments also runs into problems, which I attribute to the fact that she holds a view of causation as secondary to causal explanation. 2 3 In chapter 4 I develop an account of what I call manifest physical causation – of objective causal relations in the world of Sellars’s manifest image. Based upon McDowell’s transcendental empiricism, which takes the existence of the ordinary perceived world as a condition of the possibility of our possession of conceptual capacities, I contend that it is this picture of reality, rather than that of fundamental physics, that should be the starting point of our theorizing. Causation in the manifest image, I argue, covers the behaviour of the familiar physical world as well as that of its well-understood extensions into the special sciences and engineering. Manifest physical causation, on my account, is productive, acts through mechanisms which are almost entirely mechanical, electromagnetic, and/ or chemical, and is causally closed. In my view, normative, semantic, contentful property-instances are not part of the manifest physical causal nexus. In my final chapter I suggest a modification of Baker’s constitution account, which I call Constituted Causation, whereby higher-level – mental and other ID – causal relations are constituted, in favourable circumstances, by lower-level ones. ID causal relations belong in their own causal nexus but are connected to the manifest physical world through constitution, a relation of unity without identity. Causation and constitution are, respectively, intra- and inter-level relations, and they are non-overlapping. The constituted network of rational and normative relations bears, I believe, striking parallels with McDowell’s view of reality. According to Baker’s view of constitution, the essential properties of constituted entities subsume those of their constituters; extending this to my account enables us to say that the real cause and explanation of someone’s action is that they consciously performed it 4 rather than that certain manifest causal processes occurred at the lower level.

The co-instantiation thesis is pivotal to a significant solution to the problem of causal exclusion. But this thesis has been subject to some powerful objections. In this paper, I argue that these difficulties arise because the thesis lacks the necessary metaphysical framework in which its claims should be interpreted and understood. Once this framework is in place, we see that the co-instantiation thesis can answer its critics. The result is a rehabilitated co-instantiation solution to the troubling problem of causal exclusion. (...) But questions remain concerning the viability of certain of its applications. (shrink)

I survey recent work on mental causation. The discussion is conducted under the twin presumptions that mental states, including especially what subjects believe and desire, causally explain what subjects do, and that the physical sciences can in principle give a complete explanation for each and every bodily movement. I start with sceptical discussions of various views that hold that, in some strong sense, the causal explanations offered by psychology are autonomous with respect to those offered by the physical sciences. I (...) then proceed to views that see the problem of mental causation as that of identifying where in the physical story about us and our world lie the parts that in effect tell us abut mental causation - the kind of position that is pretty much standard in the cognitive science community - and consider issues raised by various forms of functionalism and externalism. The general thrust of my discussion is sympathetic to the story about mental causation suggested by those type-type versions of the mind-brain identity theory that allow for the possiblity of multiple realisability. I include a brief discussion of how a map-system account of belief, by contrast with a language of thought one, should understand explanations of behaviour in terms of what a subject believes.

This paper examines our pre-theoretic conception of non-supernaturalism; the thesis that all that exists is natural. It is argued that we intuitively take this thesis to be a substantive, non-dogmatic, empirically justified, not merely contingent truth. However, devicing an interpretation of non-supernaturalism that captures all aspects of this intuition is difficult. Indeed, it is found that this intuition conflates the strong inferential scope of a metaphysical claim with the modest justificatory requirements of an empirical matter of fact. As such, non-supernaturalism, (...) in itspre-theoreticform, contains an internal tension that must be navigated whenever the thesis features in systematic thinking. (shrink)
