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.

I do think that philosophy and science are very different intellectual enterprises, but that does not mean that when we get knowledge from philosophy it is a different kind of knowledge.

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.

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.

One odd thing about the current debate between religious people and atheists is that the participants don't seem to care that they entirely fail to communicate with the other side. They therefore have no account of why the religious or the atheists believe what they do, except that they are stupid or deluded. I think philosophers should try and make sense of their disputes with their opponents as far as possible without treating them as idiots. This applies to the religious participants in the debate as much as to the atheists.

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

Many people like to think that their moral or political enemies are not just wicked or wrong - as if that were not enough - but stupid or idiotic too. We tend to find this attitude too in the contemporary religion debate. It might console those on each side of the debate to think of their opponents in these terms, but if we want to make real progress in understanding what is going on here, this approach cannot help.
