Consciousness has suddenly become an extremely fashionable topic in certain scientific circles. Many thinkers are now touting consciousness as the last unconquered region of science, and theorists from many different disciplines are racing to find a "theory of consciousness" which will unlock this final secret of nature. I am suspicious about all this enthusiasm. I think that much of the brouhaha is generated by philosophical confusion. In the end, I fear, there is no special secret of consciousness, and no special key needed to unlock it.

Sometimes I despair of my philosophical colleagues. They are so conservative. I don’t mean this in a political sense. In conventional party-political terms, most professional philosophers are probably well to the left of centre. As a group, they have a strong sense of fairness and little commitment to the social status quo. But this political openmindedness doesn’t normally carry over to their day jobs. When it comes to philosophical ideas, they are congenitally suspicious of intellectual innovation. In their eyes, a good philosophical theory is one that agrees with the views found on the Clapham omnibus. Few philosophers, in the English-speaking world at least, think of philosophy as a source of radical new ideas. Rather they view it as way of systematising the everyday reactions of ordinary people.

A number of recent writers have argued that we should explain mental representation teleologically, in terms of the biological purposes of beliefs and other mental states.A rather older idea is that the truth condition of a belief is that condition which guarantees that actions based on that belief will succeed.What I want to show in this paper is that these two ideas complement each other. The teleological theory is inadequate unless it incorporates the thesis that truth is the guarantee of successful action. Conversely, the success-guaranteeing account of truth conditions is incomplete until it is placed in a teleological context.

Functionalism faces a problem in accounting for the semantic powers of beliefs and other mental states. Simple causal considerations will not solve this problem, nor will any appeal to the social utility of semantic interpretations. The correct analysis of semantic representation is a teleological one, in terms of the biological purposes of mental states: whereas functionalism focuses, so to speak, only on the structure of the cognitive mechanism, the semantic perspective requires in addition that we consider the purposes of the cognitive mechanism's parts

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
