Frank Jackson’s famous Knowledge Argument moves from the premise that complete physical knowledge is not complete knowledge about experiences to the falsity of physicalism. In recent years, a consensus has emerged that the credibility of this and other well-known anti-physicalist arguments can be undermined by allowing that we possess a special category of concepts of experiences, phenomenal concepts, which are conceptually independent from physical/functional concepts. It is held by a large number of philosophers that since the conceptual independence of phenomenal (...) concepts does not imply the metaphysical independence of phenomenal properties, physicalism is safe. This paper distinguishes between two versions of this novel physicalist strategy –Phenomenal Concept Strategy (PCS) – depending on how it cashes out “conceptual independence,” and argues that neither helps the physicalist cause. A dilemma for PCS arises: cashing out “conceptual independence” in a way compatible with physicalism requires abandoning some manifest phenomenological intuitions, and cashing it out in a way compatible with those intuitions requires dropping physicalism. The upshot is that contra Brian Loar and others, one cannot “have it both ways.”. (shrink)

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.

If physicalism is true (e.g., if every event is a fundamental-physical event), then it looks as if there is a fundamental-physical explanation of everything. If so, then what is to become of special scientific explanations? They seem to be excluded by the fundamental-physical ones, and indeed to be excellent candidates for elimination. I argue that, if physicalism is true, there probably is a fundamental-physical explanation of everything, but that nevertheless there can perfectly well be special scientific explanations as well, notwithstanding (...) eliminativist scruples concerning overdetermination and Ockham's Razor.

This book gives an account of work that I have done over a period of decades that sets out to solve two fundamental problems of philosophy: the mind-body problem and the problem of induction. Remarkably, these revolutionary contributions to philosophy turn out to have dramatic implications for a wide range of issues outside philosophy itself, most notably for the capacity of humanity to resolve current grave global problems and make progress towards a better, wiser world. A key element of the (...) proposed solution to the first problem is that physics is about only a highly specialized aspect of all that there is – the causally efficacious aspect. Once this is understood, it ceases to be a mystery that natural science says nothing about the experiential aspect of reality, the colours we perceive, the inner experiences we are aware of. That natural science is silent about the experiential aspect of reality is no reason whatsoever to hold that the experiential does not objectively exist. A key element of the proposed solution to the second problem is that physics, in persistently accepting unified theories only, thereby makes a substantial metaphysical assumption about the universe: it is such that a unified pattern of physical law runs through all phenomena. We need a new conception, and kind, of physics that acknowledges, and actively seeks to improve, metaphysical presuppositions inherent in the methods of physics. The problematic aims and methods of physics need to be improved as physics proceeds. These are the ideas that have fruitful implications, I set out to show, for a wide range of issues: for philosophy itself, for physics, for natural science more generally, for the social sciences, for education, for the academic enterprise as a whole and, most important of all, for the capacity of humanity to learn how to solve the grave global problems that menace our future, and thus make progress to a better, wiser world. It is not just science that has problematic aims; in life too our aims, whether personal, social or institutional, are all too often profoundly problematic, and in urgent need of improvement. We need a new kind of academic enterprise which helps humanity put aims-and-methods improving meta-methods into practice in personal and social life, so that we may come to do better at achieving what is of value in life, and make progress towards a saner, wiser world. This body of work of mine has met with critical acclaim. Despite that, astonishingly, it has been ignored by mainstream philosophy. In the book I discuss the recent work of over 100 philosophers on the mind-body problem and the metaphysics of science, and show that my earlier, highly relevant work on these issues is universally ignored, the quality of subsequent work suffering as a result. My hope, in publishing this book, is that my fellow philosophers will come to appreciate the intellectual value of my proposed solutions to the mind-body problem and the problem of induction, and will, as a result, join with me in attempting to convince our fellow academics that we need to bring about an intellectual/institutional revolution in academic inquiry so that it takes up its proper task of helping humanity learn how to solve problems of living, including global problems, and make progress towards as good, as wise and enlightened a world as possible.

The Empiricist or Lockean view says natural kinds do not exist objectively in nature but are practical categories reflecting use of words. The Modern, Ostensive view says they do exist, and one can refer to such a kind by ostention and recursion, assuming his designation of it is related causally to the kind itself. However, this leads to a problem: Kinds are abstract repeatables, and it seems impossible that abstractions could have causal force. In defence of the Modern view, I (...) suggest we can think of kinds as — or as like — ecological niches existing in nature, which are causally effective by virtue of the fact that they predictively determine (some) properties of the things that happen to occupy them.

Defending or attacking either functionalism or computationalism requires clarity on what they amount to and what evidence counts for or against them. My goal here is not to evaluate their plausibility. My goal is to formulate them and their relationship clearly enough that we can determine which type of evidence is relevant to them. I aim to dispel some sources of confusion that surround functionalism and computationalism, recruit recent philosophical work on mechanisms and computation to shed light on them, and (...) clarify how functionalism and computationalism may or may not legitimately come together.

Abstract: Non-reductive physicalism is commonly understood as the view that mental properties are realized by physical properties. Here, I argue that the realization relation in question is a power inheritance relation: if a property P realizes a property Q, then the causal powers of Q are a subset of the causal powers of P. Whereas others have motivated this claim by appealing to its theoretical benefits, I argue that it is in fact entailed by two theses: (i) realization is a (...) same-subject necessitation relation; (ii) properties have their causal powers derivatively on the causal powers of their bearers. Although the power inheritance claim that is defended here has many opponents, I take it that the two theses that entail it are either plausible or widely assumed. (shrink)

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.

I first met Norman Malcolm in the fall of 1963 when, as a terrified sophomore, I took his course in Free Will and Determinism at Cornell. I believe I had already heard that Malcolm was a figure of almost legendary proportions.

I argue that a certain version of physicalism, which is viewed by both its admirers and its detractors as non-reductionist, in fact entails two claims which, though not reductionist in the currently most popular sense of 'reductionist', conform to the spirit of reductionism sufficiently closely to compromise its claim to be a comprehensively non-reductionist version of physicalism. Putatively non-reductionist versions of physicalism in general, I suggest, are likely to be non-reductionist only in some senses, but not in others, and hence (...) to disappoint those who wish to be physicalists but still to remain soft and cuddly non-reductionists.

Colin McGinn proposes that acceptance of the supervenience of the modal on the actual is the natural form of expression of a non-objectual realism about modality. Here, some of the difficulties that arise in applying theses of supervenience to the modal-actual case are discussed. It is then argued: 1)that the truth of many such theses is determined on uncontroversial modal logical and conceptual grounds, and 2) that this and other independent considerations render it highly implausible that the affirmation of modal-actual (...) supervenience amounts to a modal realism.

It is widely assumed that functional and dispositional properties are not identical to their physical base, but that there is some kind of asymmetrical ontological dependence between them. In this regard, a popular idea is that the former are realized by the latter, which, under the non-identity assumption, is generally understood to be a non-causal, constitutive relation. In this paper we examine two of the most widely accepted approaches to realization, the so-called ‘flat view’ and the ‘dimensioned view’, and we (...) analyze their explanatory relevance in the light of a number of examples from the life sciences, paying special attention to developmental phenomena. Our conclusion is that the emphasis placed by modern-day biology on such properties as variability, evolvability, and a whole collection of phenomena like modularity, robustness, and developmental constraint or developmental bias requires the adoption of a much more dynamic perspective than traditional realization frameworks are able to capture.

Consider the idea that some entities are more fundamental than others, some entities ‘ground’ other, less fundamental, entities. What is it for something to be more fundamental than another, or for something to ‘ground’ something else? This paper urges the rejection of conceptions of grounding and fundamentality according to which reality has a hierarchical structure in which higher-level entities are taken to be distinct from but metaphysically dependent on more fundamental lower-level entities. Truthmaking is offered as an apt replacement for (...) at least some of the many applications of grounding. (shrink)
