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.

Since I don't believe in externalism, I don't think it can explain consciousness!

Naturalism is a methodological rather than a metaphysical view. It's because I am a naturalist, actually, that I am sceptical about physicalism.

Catholicism is the most philosophical branch of Christianity.

Science will always raise philosophical questions like, is any scientific theory or model correct? How do we know? Are unobserved things real? etc. and it seems to me of great importance that these questions are not just left to scientists, but that there are thinkers who make it their business to think as clearly and slowly about these questions as it is possible to. Great scientists do not always make the best philosophers.

The thing I think I have learned from Wittgenstein is the importance of not making things up: philosophers should not invent problems, and they should also be conscious of the risk of inventing pointless 'technical' machinery which do not offer real explanations, but often just re-state the known facts in a more complex way.

I have a general moral: great philosophers may be great, but that is not a reason to follow them. Don't be a follower. Work it out for yourself.
