Holton, we acknowledge, has given a good counter-example to a theory, and that theory is interesting and worth refuting. The theory we have in mind is like Smith's, but is more reductionist in spirit. It is a theory that ties value to Reason and to processes of reasoning, or inference - not to the recognition of reasons and acting on reasons. Such a theory overestimates the importance of logic, truth, inference, and thinking things through for yourself independently of any ideas about where you might end up. Now it might well be thought that any Kantian theory of value would need to be tied to just such a conception of Reason. But while the theory behind The Moral Problem is Kantian in some very salient respects, the survival of Smith's analysis of value in the face of Holton's argument is very instructive. It teaches us a memorable moral: that a Kantian theory like Smith' s does not need to be tied - even loosely - to an overly intellectualised, logocentric conception of Reason.

According to the new family of theories that emerged around the second half of the nineteenth century, time is more similar to space than it had been construed to be under the previous family of theories. These new theories of time treat time as being a “fourth dimension” that is much more like the three spatial dimensions than it was imagined to be under the older rival theories. Over the two centuries following Newton, the key concepts of graphs and the differential and integral calculus, trickled out into a wide intellectual community. Mc Taggart's theorem purports to be a disproof of all the old theories of time – on the grounds that they are logically inconsistent. It also purports to be a disproof of all the new theories of time – on the grounds that what they describe as “time” is simply not time, properly so‐called.

Frank Jackson argued, in an astronomically frequently cited paper on 'Epiphenomenal qualia '[Jackson 1982 that materialism must be mistaken. His argument is called the knowledge argument. Over the years since he published that paper, he gradually came to the conviction that the conclusion of the knowledge argument must be mistaken. Yet he long remained totally unconvinced by any of the very numerous published attempts to explain where his knowledge argument had gone astray. Eventually, Jackson did publish a diagnosis of the reasons why, he now thinks, his knowledge argument against materialism fails to prove the falsity of materialism [Jackson 2005. He argues that you can block the knowledge argument against materialism - but only if you tie yourself to a dubious doctrine called representationalism. We argue that the knowledge argument fails as a refutation of either representational or nonrepresentational materialism. It does, however, furnish both materialists and dualists with a successful argument for the existence of distinctively first-person modes of acquaintance with mental states. Jackson's argument does not refute materialism: but it does bring to the surface significant features of thought and experience, which many dualists have sensed, and most materialists have missed.

This paper concerns the semantics of belief-sentences. I pass over ontologically lavish theories which appeal to impossible worlds, or other points of reference which contain more than possible worlds. I then refute ontologically stingy, quotational theories. My own theory employs the techniques of possible worlds semantics to elaborate a Fregean analysis of belief-sentences. In a belief-sentence, the embedded clause does not have its usual reference, but refers rather to its own semantic structure. I show how this theory can accommodate quantification into belief-contexts. I close with skirmishes against the threat posed by the Liar Paradox.

I. Logic, rationality and ideology Herbert Marcuse once claimed that the ‘“rational” is a mode of thought and action which is geared to reduce ignorance, destruction, brutality, and oppression.’ He echoed a widespread folk belief that a world in which people were rational would be a better world. This could be taken as an optimistic empirical conjecture: if people were more rational then probably the world would be a better place (a trust that ‘virtue will be rewarded’, so to speak). However, it is also worth considering a stronger hypothesis: that if something did not reduce ignorance, destruction, brutality, and oppression then it would not constitute rationality. On this view there is no mere correlation between rationality and a propensity toward reduction in ignorance and the rest, it is the propensity to reduce ignorance, destruction, brutality and oppression which in part constitutes rationality. Call this a broad conception of rationality, because it expands beyond the epistemic goal of reducing ignorance, and reaches out to moral concerns like oppression.

What makes the words we speak mean what they do? Possible-worlds semantics articulates the view that the meanings of words contribute to determining, for each sentence, which possible worlds would make the sentence true, and which would make it false. M. J. Cresswell argues that the non-semantic facts on which such semantic facts supervene are facts about the causal interactions between the linguistic behaviour of speakers and the facts in the world that they are speaking about, and that the kind of causation involved is best analysed using David Lewis's account of causation in terms of counterfactuals. Although philosophers have worked on the question of the connection between meaning and linguistic behaviour, it has mostly been without regard to the work done in possible-worlds semantics, and Language in the world is the first book-length examination of this problem.
