We have no proper understanding of the relationship between conscious thought and conscious sensation. The various forms of thought and sensation are underpinned by very different neural mechanisms; so how can the neural correlate of their conscious natures be the same? I don't think we are yet in a position to make such speculations. To make progress, we have to have a good conception of the phenomenology of consciousness, among other things.

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.

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.

I do think it's important to distinguish between intentionalism about consciousness and externalism about consciousness. Intentionalism says that consciousness is a form of intentionality - the representation of things to the mind. Externalism says that these things have to exist in order for them to be represented, or presented. These are different views.

Although a lot of my work on the mind has been rather abstract and philosophical, I'm interested in psychology and neuroscience and I don't think there are any principled distinctions between the kind of knowledge we get from science and the knowledge we get from philosophy.

Catholicism is the most philosophical branch of Christianity.

I'm not a militant atheist, just an atheist. In fact, in a largely atheist country like the UK I think it's a bit silly to be a militant atheist.
