In this paper I want to explore the nature of phenomenal concepts by comparing them with perceptual concepts. Phenomenal concepts have been drawn to the attention of philosophers by recent debates in the philosophy of mind. Most obviously, their existence is demonstrated by Frank Jackson’s thought-experiment about Mary, the expert on the science of colour vision who has never had any colour experiences herself. It is widely agreed that, when Mary does first see something red, she acquires a new concept of red experiences, distinct from any of her previous scientific concepts of such experiences. This new mode of reference is an example of a phenomenal concept. Recent interest in phenomenal concepts is independent of views about the ontological significance of Jackson’s Mary argument. Thus phenomenal concepts are acknowledged both (a) by ontological dualists who take the Mary argument to demonstrate the non-physicality of conscious phenomena and (b) by physicalist monists who insist that Mary’s new concept refers to nothing but a material state that she could always refer to using her old scientific concepts. How then do phenomenal concepts work? Here there is far less consensus. Among those who trade in phenomenal concepts, some take them to be sui generis (Tye, 2003, Chalmers, 2003), while others have variously likened them to recognitional concepts (Loar, 1990), to demonstratives (Horgan 1984, Papineau 1993, Perry 2001), or to quotational terms (Papineau 2002, Balog forthcoming). In my Thinking about Consciousness (2002), I developed a ‘quotational-indexical’ of phenomenal concepts account on roughly the following lines. To have a phenomenal concept of some experience, you must be able introspectively to focus on it when you have it, and to....

The main puzzle about theoretical definitions is that nothing seems to decide which assumptions contribute to such definitions and which do not. I argue that theoretical definitions are indeed imprecise, but that this does not normally matter, since the definitional imprecision does not normally produce indeterminacy of referential value. Sometimes, however, the definitional imprecision is less benign, and does generate referential indeterminacy. In these special cases, but not otherwise, it is necessary to refine the term's definition

It is widely supposed that the Everettian account of quantum mechanics has difficulties with probability. In this paper I shall argue that those who argue against the Everettian interpretation on this basis are employing a double standard. It is certainly true that there are philosophical puzzles about probability within the Everettian theory. But I shall show that orthodox metaphysics has even worse problems with probability than Everettianism. From this perspective, orthodox metaphysicians who criticise Everettians about probability are a classic case of a pot calling the kettle black.

This paper defends scientific realism from the pessimistic meta-induction from past reference failure. It allows that a descriptive theory of reference implies that scientific terms characteristically fail of determinate reference. But it argues that a descriptive theory of reference also implies an equivalence between scientific theories and quantificational claims in the style of Ramsey. Since these quantificational claims do not use any of the referentially suspect scientific terms, they can be approximately true even when those terms fail to refer determinately.Keywords: Science; Realism; Ramsey sentences; Approximate truth; Reference.

To begin with the former, representation is as familiar as it is puzzling. The English sentence ‘ Santiago is east of Sacramento’ represents the world as being a certain way. So does my belief that Santiago is east of Sacramento. In these examples, one item—a sentence or a belief—lays claim to something else, a state of affairs, which may be far removed in space and time. This is the phenomenon that naturalist theories of meaning aim to explain. How is it possible for one thing to stand for something else in this way?

According to an influential view in contemporary cognitive science, many human cognitive capacities are innate. The primary support for this view comes from ‘poverty of stimulus’ arguments. In general outline, such arguments contrast the meagre informational input to cognitive development with its rich informational output. Consider the ease with which humans acquire languages, become facile at attributing psychological states (‘folk psychology’), gain knowledge of biological kinds (‘folk biology’), or come to understand basic physical processes (‘folk physics’). In all these cases, the evidence available to a growing child is far too thin and noisy for it to be plausible that the underlying principles involved are derived from general learning mechanisms. This only alternative hypothesis seems to be that the child’s grasp of these principles is innate. (Cf. Laurence and Margolis, 2001.).

What does it mean for someone to exist? What is truth? Are we free to choose to think or act? What is consciousness? Is human cloning justifiable? These are just some of the questions philosophers have attempted to answer, striking right at the heart of what it means to be human. This important new books shows that philosophy need not be dry or intimidating. Its highly original treatment, combining philosophical analysis, historical and biographical background and thought-provoking illustrations, simultaneously informs and stimulates the reader. Western Philosophy: An Illustrated Guide is structured thematically, in terms of major issues, with chapters on World, Mind and Body, Knowledge, Faith, Ethics and Aesthetics, and Society. Cutting across this organization by theme is a parallel organization that focuses on the great thinkers and their influence, as well as the schools or "-isms" to which they subscribed. A highly accessible introduction to the subject, founded upon impeccable academic scholarship, Western Philosophy: An Illustrated Guide offers life-changing perspectives on what really matters.

Galen Strawson (2006) thinks it is 'obviously' false that 'the terms of physics can fully capture the nature or essence of experience' (p. 4). He also describes this view as 'crazy' (p. 7). I think that he has been carried away by first impressions. It is certainly true that 'physicSalism', as he dubs this view, is strongly counterintuitive. But at the same time there are compelling arguments in its favour. I think that these arguments are sound and that the contrary intuitions are misbegotten. In the first two sections of my remarks I would like to spend a little time defending physicSalism, or 'straightforward' physicalism, as I shall call it ('S' for 'straightforward', if you like). I realize that the main topic of Strawson's paper is panpsychism rather than his rejection of straightforward physicalism. But the latter is relevant as his arguments for panpsychism depend on his rejection of straightforward physicalism, in ways I shall explain below.

My first university was in my home town, Durban, in the mid-1960s. I was doing a mathematics degree but most of my friends were doing arts subjects. Sartre and Marx were the thinkers of the moment and my friends would press their (mostly illegal) writings on me. Ideologically I was entirely sympathetic, but intellectually they didn’t do much for me—too obscure, too difficult, too dogmatic. In my final year I chanced on Ayer’s The Problem of Knowledge. It wasn’t exactly relevant to apartheid South Africa, but I consumed it eagerly. Through Ayer I was led to Russell’s logical atomism. What appealed to me in both these authors was the sense of solving fundamental problems through careful logical analysis. Of course, in retrospect we can see that their limpid style concealed many doubtful assumptions. Yet you could always see exactly what they were claiming and how the argument was supposed to go. I still think that this is the best way to do philosophy.
