Many philosophers and neuroscientists defend a view we express with the slogan that mental science is neuroscience. We argue that there are two ways of interpreting this view, depending on what is meant by ‘neuroscience’. On one interpretation, the view is that mental science is cognitive neuroscience, where this is the science that integrates psychology with the biology of the brain. On another interpretation, the view is that mental science is biological neuroscience, where this is the investigation concerned with the chemistry, physiology and anatomy of neurons and neuronal assemblies. Since the claim about cognitive neuroscience is a scientific triviality, we concentrate on the claim about biological neuroscience, and criticise two initially promising lines of argument for it, one prompted by reflection on the history of biology, and one prompted by reflection on the neurophysiological process known as long‐term potentiation, which may be implicated in learning. We argue that neither of these arguments is successful in supporting the view that mental science is biological neuroscience.

THOMSON, Judith Jarvis (1929– ) Judith Jarvis Thomson received her BA from Barnard College in 1950, her MA from Cambridge University in 1956, and a Ph.D. from Columbia University in 1959. Her first teaching position was at Barnard where she was a lecturer from 1955–9, an instructor from 1959–60, and then Assistant Professor from 1960–2. In 1963, she moved to Boston, first as an Assistant Professor at Boston University (1963–4), and then to the Massachusetts Institute of Technology, where she has remained ever since. She became full Professor in 1969, and between 1990 and 1996 held the Laurence S. Rockefeller Chair in Philosophy at MIT. She has received a large number of awards and honours, and contributed in many ways to professional philosophy in America. In 1992, she held the Presidency of the American Philosophical Association (Eastern Division), and in 1999, she gave the Tanner Lectures at Princeton University. She is Chair of the American Philosophical Association's Board of Officers for 2002-5, and gave the Association's Carus Lectures in 2003. She is also widely acknowledged as one of the best teachers of philosophy, and the excellence of the graduate program at MIT is due in no small measure to her influence. Thomson’s philosophical work ranges widely but her main areas of concentration are moral philosophy and metaphysics. In moral philosophy, Thomson has made seminal contributions to all three sub-fields of that discipline, applied ethics, moral theory and metaethics. (Indeed, the nature of her work makes these divisions seem somewhat artificial.) The papers gathered together in Rights, Restitution and Risk, and, since then, papers such as, ‘Self- Defence’, ‘Physician Assisted Suicide: Two Moral Arguments’ and ‘Assisted Suicide: The Philosophers Brief’ (written jointly with John RAWLS, Robert NOZICK, Ronald DWORKIN.

The exclusion argument is widely thought to put considerable pressure on dualism if not to refute it outright. We argue to the contrary that, whether or not their position is ultimately true, dualists have a plausible response. The response focuses on the notion of ‘distinctness’ as it occurs in the argument: if 'distinctness' is understood one way, the exclusion principle on which the argument is founded can be denied by the dualist; if it is understood another way, the argument is not persuasive.

It is sometimes suggested that expressivism in meta-ethics is to be criticized on grounds which do not themselves concern meta-ethics in particular, but which rather concern philosophy of language more generally. Frank Jackson and Philip Pettit (1998; see also Jackson and Pettit 1999, and Jackson 2001) have recently advanced a novel version of such an argument. They begin by noting that expressivism in its central form makes two claims—that ethical sentences are not truth evaluable, and that to assert an ethical sentence is to express one’s desires or feelings rather than to report a fact. They then argue that, given some plausible premises in the philosophy of language emanating mainly from Locke, the two central claims of expressivism are contradictory: when combined with the plausible premises, they say, the second claim refutes the first. The purpose of this paper is to formulate Jackson and Pettit’s Lockean argument, and to suggest that it fails

Physicalism, the thesis that everything is physical, is one of the most controversial problems in philosophy. Its adherents argue that there is no more important doctrine in philosophy, whilst its opponents claim that its role is greatly exaggerated. In this superb introduction to the problem Daniel Stoljar focuses on three fundamental questions: the interpretation, truth and philosophical significance of physicalism. In answering these questions he covers the following key topics: (i)A brief history of physicalism and its definitions, (ii)what a physical property is and how physicalism meets challenges from empirical sciences, (iii)'Hempel’s dilemma’ and the relationship between physicalism and physics, (iv)physicalism and key debates in metaphysics and philosophy of mind, such as supervenience, identity and conceivability, and (v)physicalism and causality. Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making Physicalism ideal for those coming to the problem for the first time.

The aim of this book is to argue that issues in metaphysics—in particular issues about the nature of states and causation—will have a significant impact in philosophy of mind. As Steward puts it: “the category of state has been so grossly misunderstood that some theories of mind which are supposed to encompass entities traditionally regarded as falling under the category, e.g., beliefs and desires, cannot so much as be sensibly formulated, once we are clearer about the nature of states”. According to Steward, there are two different approaches to the metaphysics of states: a view according to which states are events, and a view according to which states are facts. Steward says that many discussions in philosophy of mind proceed on the basis of the first view, and thus proceed on what she calls the particularist approach. Steward argues that the particularist approach is mistaken, that states are facts, and that if we would recognize this, many of the problems and positions in philosophy of mind would disappear.

Pereboom (2011) is an extremely rich investigation of some of the central questions in contemporary philosophy of mind. In the foreground are the usual suspects from the current scene, but Kant and Russell loom in the background, and footnotes elaborate connections to people as apparently remote from the normal run of things as Dilthey and Derrida. With so much covered one is inevitably forced to focus on some things, setting aside others. Here I will concentrate on two ideas contained in the first part of the book: Pereboom's ‘qualitative inaccuracy hypothesis’ and his criticisms of ‘the epistemic strategy’, a strategy I have defended in a number of places (e.g. Stoljar 2006, 2009).

Many philosophers of mind are concerned to defend the thesis called physicalism ; many others are concerned to refute it. Nevertheless, there is no generally agreed on idea of what physicalism is, and why it should matter whether the mental is physical. My thesis consists of four essays whose concern is with what physicalism is in its most plausible version, and what the importance of the thesis might be for the philosophy of mind. ;I begin with the question of whether it is possible to hold physicalism in a nonreductive form. Nonreductive physicalism is a doctrine that divides into two parts. The first part--the physicalist part--is that mental properties and facts supervene on physical properties and facts. The second part--the nonreductivist part--is that this supervenience thesis does not imply that mental properties and facts are reduced to physical properties and facts. In chapter one, I argue that, when properly understood, these two claims are not cotenable. ;In chapter two, I consider a different way of developing nonreductive physicalism. ;My discussion of nonreductive physicalism has a conditional conclusion: nonreductive physicalism reduces to reductive physicalism, and thus, if one wants to be a physicalist, one must be a reductive physicalist. Accordingly, in chapter three, I turn to reductive physicalism: the thesis that mental properties simply are physical properties. ;In the final chapter, I assess the reasons for believing physicalism. Physicalists have a number of different reasons for believing their doctrine, but perhaps the most widespread is the idea that one should believe physicalism because to renounce it would be, as Schiffer has put it, "to renounce the scruples of the natural scientist". I reply that this is a mistake born from missing an ambiguity in the word 'physical'. In one sense, 'physical' applies to a property or fact which the empirical sciences are in the best position to describe. In another sense, 'physical' applies to a property or fact which a certain sub-class of the empirical sciences are in the best position to describe, namely, the subclass which includes contemporary physics, chemistry, biology and neuroscience. What is at issue in the philosophy of mind is physicalism where 'physical' has this second stricter sense. However, under that interpretation, to renounce physicalism is not, I argue, to renounce the scruples of the natural scientist. Moreover, under that interpretation, there is no strong pressure to revise our conception of what a mental property is in order to ensure the truth of physicalism.

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience.

Mary is confined to a black-and-white room, is educated through black-and-white books and through lectures relayed on black-and white television. In this way she learns everything there is to know about the physical nature of the world. She knows all the physical facts about us and our environment, in a wide sense of 'physical' which includes everything in completed physics, chemistry, and neurophysiology, and all there is to know about the causal and relational facts consequent upon all this, including of course functional roles. If physicalism is true, she knows all there is to know. For to suppose otherwise is to suppose that there is more to know than every physical fact, and that is just what physicalis.

This paper defends a novel view of ‘what it is like’-sentences, according to which they attribute certain sorts of relations—I call them ‘affective relations’—that hold between events and individuals. The paper argues in detail for the superiority of this proposal over other views that are prevalent in the literature. The paper further argues that the proposal makes better sense than the alternatives of the widespread use of Nagel’s definition of conscious states and that it also shows the mistakes in two prominent suggestions about the definition when properly understood: first, that it is empty and uninformative, and second, that it leads directly to a substantial claim in the theory of consciousness, namely that an individual is in a conscious state only if the individual is aware of their being in that state.

Perhaps more than any other philosopher of mind, Ned Block synthesizes philosophical and scientific approaches to the mind; he is unique in moving back and forth across this divide, doing so with creativity and intensity. Over the course of his career, Block has made groundbreaking contributions to our understanding of intelligence, representation, and consciousness. Blockheads! (the title refers to Block's imaginary counterexample to the Turing test—and to the Block-enthusiast contributors) offers eighteen new essays on Block's work along with substantive and wide-ranging replies by Block
