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.

We often do metaphysics by intuitions about possible cases. An example is the argument for functionalism about belief and desire. The argument starts from the premise that, intuitively, it is not possible for belief and desire to vary independently of functional nature —functional duplicates are necessarily belief-desire duplicates—and concludes that belief and desire are functional states. An equally famous example is the argument against functionalism for sensory qualities. The argument starts from the premise that, intuitively, it is possible for sensory nature to vary independently of functional nature—functional duplicates might be sensory inverts—and concludes that sensory states are not functional states.

David Lewis's untimely death on 14 October 2001 deprived the philosophical community of one of the outstanding philosophers of the 20th century. As many obituaries remarked, Lewis has an undeniable place in the history of analytical philosophy. His work defines much of the current agenda in metaphysics, philosophical logic, and the philosophy of mind and language. This volume, an expanded edition of a special issue of the Australasian Journal of Philosophy, covers many of the topics for which Lewis was well known, including possible worlds, counterpart theory, vagueness, knowledge, probability, essence, fiction, laws, conditionals, desire and belief, and truth. Many of the papers are by very established philosophers; others are by younger scholars including many he taught. The volume also includes Lewis's Jack Smart Lecture at the Australian National University, 'How Many Lives has Schrödinger's Cat?', published here for the first time. Lewisian Themes will be an invaluable resource for anyone studying Lewis's work and a major contribution to the many topics that he mastered.

_Language, Names, and Information_ is an important contribution to philosophy of language by one of its foremost scholars, challenging the pervasive view that the description theory of proper names is dead in the water, and defending a version of the description theory from a perspective on language that sees words as a wonderful source of information about the nature of the world we live in. Challenges current pervasive view that the description theory of reference for proper names has been refuted Discusses several topics at the center of current debates, including representation and information, two-dimensionalism, possible worlds, and broad vs. narrow content Maintains the conversational and somewhat informal tone of the original lectures upon which the book is based.

We make powerful motor cars by suitably assembling items that are not themselves powerful, but we do not do this by 'adding in the power' at the very end of the assembly line; nor, if it comes to that, do we add portions of power along the way. Powerful motor cars are nothing over and above complex arrangements or aggregations of items that are not themselves powerful. The example illustrates the way aggregations can have interesting properties that the items aggregated lack. What can we say of a general kind about what can be made from what by nothing over and above aggregation? I think that this is the key issue that Galen Strawson (2006) puts so.

ConclusionToken-token identity theorists do not and need not deny that it may frequently be the same (kind of) brain state which on different occasions fills the functional rôle definitive of a given mental state. That is not at issue. What is at issue is whether functionally-oriented identity theorists should make two claims or three claims.The two claims they customarily make are, first, that each instance of a mental state is an instance of a brain state, and, secondly, that being in a mental state is having in one a state filling the relevant functional rôle. But to be in a mental state is to have that state in one. To be in pain is to have pain, to desire water is to have desire for water, and so on; just as to be poisoned is to have poison in you. (It is to have what is poison for you at the time, of course; and likewise for pain, desire and so on.)Our paper has been about a third sort of claim — relating particularly not to being in a mental state, nor to instances of that state, but to the mental state itself. We have argued that functionally-oriented identity theorists can and should make, in addition to the first two claims, the third type-type identity claim that mental states are brain states. Consequently a token brain state is a token of pain in a derivative sense. What makes it a token of pain is that it is a token of the type of brain state which realizes the pain-rôle for the organism at the time.

I discuss whether Michael Tye, in Ten Problems of Consciousness. Cambridge, Massachusetts: MIT Press, 1966, holds that phenomenal properties are neurological properties, but that what gives them their phenomenal property names are their highly complex interconnections with other neurological properties and, most especially, subjects' surroundings. Or, alternatively, whether he holds that they are higher-level, wide functional properties in the sense of being properties of having properties that fill some specified wide or distal roles
