Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.

Music is one of my big interests - I once had a rather fanciful ambition to be a singer - and of course music is philosophically fascinating. What it is for music to express emotion strikes me as one of the most difficult questions - it's hard to say what it precisely means, although it plainly does mean something. But whenever I have tried to say something about this, it has come out as either banal or pretentious or both.

One philosophically fascinating aspect of Catholicism is the very strange conception of reality it presents (the incarnation, the eucharist, judgement day etc.).

I do not claim to have any developed or sophisticated views in political philosophy, but I think that one of the lessons of the last few hundred years of history is that the greatest threat to human prosperity and well-being is fanaticism and intolerance, even in the name of apparently laudable goals.

Unlike art which contains a message, wine conveys nothing, it has no intellectual or cognitive content

Would it be better if religions were to disappear? I have no idea. Since I do not have any confidence in the association of truth with virtue, I am not sure if the world would be a better place if people believed more true things. But what is undeniable is that we cannot understand our own culture unless we recognise that it was formed, for good or bad, as a Christian culture. It's an illusion that we could somehow recover a human essence which is independent of the way it was created by culture.

A lot of humanists treat religion as if it were simply a kind of rival cosmological hypothesis, and that this is all it is. My view is that to the extent that religions are cosmological hypotheses, this is not the only important thing about them, and we - atheists- will never get a proper understanding of what religion is if we focus too much on the cosmology.
