Twenty years ago, Richard Boyd suggested that physicalism could be formulated by appeal to a notion of realization, with no appeal to the identity of the non-physical with the physical. In (Melnyk 2003), I developed this suggestion at length, on the basis of one particular account of realization. I now ask what happens if you try to formulate physicalism on the basis of other accounts of realization, accounts due to LePore and Loewer and to Shoemaker. Having explored two new formulations (...) of physicalism, I conclude that my 2003 formulation remains the most promising. (shrink)

Grounding is all the rage in analytical metaphysics. But here I give three reasons for not appealing to a primitive relation of grounding in formulating physicalism. (1) It probably can't do the key job it would need to do. (2) We don't need it, since we already have realization. (3) It is probably not even consistent with physicalism.

In earlier work, I proposed and defended a formulation of physicalism that was distinctive in appealing to a carefully-defined relation of physical realization. Various philosophers (Robert Francescotti, Daniel Stoljar, Carl Gillett, and Susan Schneider) have since presented challenges to this formulation. In the present paper, I aim to show that these challenges can be overcome.

Can physicalism (or materialism) be non-reductive? I provide an opinionated survey of the debate on this question. I suggest that attempts to formulate non-reductive physicalism by appeal to claims of event identity, supervenience, or realization have produced doctrines that fail either to be physicalist or to be non-reductive. Then I treat in more detail a recent attempt to formulate non-reductive physicalism by Derk Pereboom, but argue that it fares no better.

This paper argues against both conceptual and linguistic analysis as sources of a priori knowledge. Whether such knowledge is possible turns on the nature of concepts. The paper's chief contention is that none of the main views about what concepts are can underwrite the possibility of such knowledge.

This is a critical, but sympathetic, examination of the manifesto for naturalized metaphysics that forms the first chapter of James Ladyman and Don Ross's 2006 book, Every Thing Must Go, but it has wider implications than this description suggests.

This paper presents an irreducibly inductive argument for physicalism based on the causal closure of the physical (for which it argues), and defends it against various detractors.

A critical study of Rea's book, focusing on his case for three theses: that naturalism must be viewed as a ‘research programme’; that naturalism ‘cannot be adopted on the basis of evidence’; and that naturalists cannot be justified in accepting realism about material objects.

Critical comments on David Papineau's idea that people find physicalism about phenomenal consciousness unbelievable because they commit what he calls the 'antipathetic fallacy'.

Derk Pereboom has recently elaborated a formulation of non-reductive physicalism in which supervenience does not play the central role and realization plays no role at all; he calls his formulation “robust non-reductive physicalism”. This paper argues that for several reasons robust non-reductive physicalism is inadequate as a formulation of physicalism: it can only rule out fundamental laws of physical-to-mental emergence by stipulating that there are no such laws; it fails to entail the supervenience of the mental on the physical; it (...) appeals to two relations that are physicalistically unacceptable; and it rules out certain epistemically possible ways that the world might turn out to be according to current physics. This paper further argues that the difficulties faced by Pereboom’s robust non-reductive physicalism can all be avoided if physicalism is instead formulated by appeal to a carefully-defined relation of realization.

Materialism is nearly universally assumed by cognitive scientists. Intuitively, materialism says that a person’s mental states are nothing over and above his or her material states, while dualism denies this. Philosophers have introduced concepts (e.g., realization, supervenience) to assist in formulating the theses of materialism and dualism with more precision, and distinguished among importantly different versions of each view (e.g., eliminative materialism, substance dualism, emergentism). They have also clarified the logic of arguments that use empirical findings to support materialism. Finally, (...) they have devised various objections to materialism, objections that therefore serve also as arguments for dualism. These objections typically center around two features of mental states that materialism has had trouble in accommodating. The first feature is intentionality, the property of representing, or being about, objects, properties, and states of affairs external to the mental states. The second feature is phenomenal consciousness, the property possessed by many mental states of there being something it is like for the subject of the mental state to be in that mental state.

This paper argues in unprecedented empirical and philosophical detail that, given only what science has discovered about pain, we should prefer the materialist hypothesis that pains are purely material over the dualist hypothesis that they are immaterial. The empirical findings cited provide strong evidence for the thesis of empirical supervenience: that to every sort of introspectible change over time in pains, or variation among pains at a time, there corresponds in fact a certain sort of simultaneous neural change over time, (...) or variation at a time. The empirical supervenience of pain on the neural is shown in turn to favor the hypothesis that pains are, in a sense that is made precise, purely material. (shrink)

This critical study takes Nagel's book to task for its obscurity, and for its under-argued rejection of naturalism.

Though there is much else in Levine's book that is also worthy of discussion, this critical study focuses exclusively on his central positive thesis that phenomenal consciousness exhibits two features that “both resist explanatory reduction to the physical: subjectivity and qualitative character” (p. 175).

This paper concerns Sydney Shoemaker's view, presented in his book, Physical Realization (Oxford University Press, 2007), of how mental properties are realized by physical properties. That view aims to avoid the "too many minds" problem to which he seems to be led by his further view that human persons are not token-identical with their bodies. The paper interprets and criticizes Shoemaker's view.

Review of Robert Kirk's The Conceptual Link From Physical To Mental (Oxford University Press, 2013).

I develop the conjecture that “naturalism” in philosophy names not a thesis but a paradigm in something like Thomas Kuhn’s sense, i.e., a set of commitments, shared by a group of investigators, whose acceptance by the members of the group powerfully influences their day-to-day investigative practice. I take a stab at spelling out the shared commitments that make up naturalism, and the logical and evidential relations among them.

The paper argues that a broadly functionalist picture of psychological phenomena is quite consistent with at least one interesting thesis of psychological reductionism.

This critical study aims mainly to do two things: (i) throw some cold water on the claim that supervenience can be used to formulate a doctrine of non-reductive physicalism, and (ii) rebut an argument for physicalism offered (separately) by David Papineau and Barry Loewer. -/- The title alludes to the following lyric from "Mary Poppins", and was intended to hint that there is less to supervenience than meets the eye: -/- It's supercalifragilisticexpialidocious Even though the sound of it is something (...) quite atrocious If you say it loud enough, you'll always sound precocious Supercalifragilisticexpialidocious.

Substantial review of Michael Rea's, World without design: the ontological consequences of naturalism. It is an improved version of my paper, "Rea On Naturalism" in Philo, 2004, revised in light of Rea's comments on the earlier paper. The discussion focuses on Rea’s case for three of his theses: that naturalism must be viewed as a ‘research programme’; that naturalism ‘cannot be adopted on the basis of evidence’, as he puts it; and that naturalists cannot be justified in accepting realism about (...) material objects.

This is a critical notice of Timothy Williamson's, The Philosophy of Philosophy (Blackwell, 2007). It focuses on criticizing the book's two main positive proposals: that we should “replace true belief by knowledge in a principle of charity constitutive of content”, and that “the epistemology of metaphysically modal thinking is tantamount to a special case of the epistemology of counterfactual thinking”.

This paper is guided by, and begins to make plausible, the idea that there can be a naturalistic metaphilosophy, i.e., an inquiry that takes philosophy as an object of study in something like the way that contemporary (naturalistic) philosophy of science takes science as an object of study. The paper’s more specific goal is to ventilate certain provocative speculations concerning the character of philosophy’s cognitive achievement, especially over time. But this more specific goal will be approached indirectly, through addressing in (...) a preliminary way the question what the proper relationship is between philosophy and the study of philosophy’s history.

This is a critical study of Sydney Shoemaker's, Physical Realization (Oxford University Press, 2007). It focuses on (i) the relationship between his subset theory of realization and the higher-order property theory of realization, and (ii) his attempt to solve the problem of mental causation.

This paper aims to show that David Chalmers' conceivability argument against physicalism, as presented in his 1996 book, The Conscious Mind, is inconclusive. The key point is that, while the argument seems to assume that someone competent with a given concept thereby has access to the primary intension of the concept, there are physicalist-friendly views of conceptual competence which imply that this assumption is not true.

My goal in this paper is to provide critical discussion of Michael Rea’s case for three of the controversial theses defended in his World Without Design (Oxford University Press, 2002): (1) that naturalism must be viewed as what he calls a “research program”; (2) that naturalism “cannot be adopted on the basis of evidence,” as he puts it; and (3) that naturalists cannot be justified in accepting realism about material objects.
