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

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....

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?

When I woke up a few days ago, the following thoughts ran through my mind. ‘I need a haircut. If I don't get it first thing this morning, I won't have another chance for two weeks. But if I go to the barber down the road, he'll want to talk to me about philosophy. So I'd better go to the one in Camden Town. The tube will be very crowded, though. Still, it's a nice day. Why don't I just walk there? It will only take twenty minutes. So I'd better put on these shoes now, have breakfast straight away, and then set out for Camden.’

Russell’s place in the public eye was maintained by a steady stream of writing for the general reader. He no longer held any academic position, and needed to support himself and his family by his pen. While he continued to do some technical work in philosophy, more of his energies were devoted to journalism and other popular writings. He was in great demand. His distinctive prose and dry wit enabled him to puncture the fusty assumptions of contemporary thinking, and his rationalist alternatives struck many readers as a liberating antidote to conventional morality.

This paper defends the view that the asymmetry of causation can be explained in terms of probabilistic relationships between event types. Papineau first explores three different versions of the "fork asymmetry", namely David Lewis' asymmetry of overdetermination, the screening-off property of common causes, and Spirtes', Glymour's and Scheines' analysis of probabilistic graphs. He then argues that this fork asymmetry is both a genuine phenomenon and a satisfactory metaphysical reduction of causal asymmetry. In his final section he shows how this reduction can account for the relevance of causal direction to human agency, and in particular for the fact that we can manipulate causes to influence their effects, but not vice versa

The newest addition to the successful Oxford Readings in Philosophy series, this collection contains the most important contributions to the recent debate on the philosophy of science.
