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.

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

Taken as hypotheses, religious claims do very badly. Yet the striking fact is that this does not worry Christians.

There's that great Irish joke: a man is lost in the countryside, stops a passer-by: 'how do I get to Dublin?'. The passer-by says 'well, I wouldn't start from here'. Rather than starting by talking in the abstract about materialism, dualism, 'material stuff' and things like that in regard to the mind, I would rather start from somewhere else.

If I was going to sum up my approach to this whole mind issue, I would say this: the question is often formulated in a very bad way - for example, by posing the question in terms of stuff. It's better to start with the things we do know: for example, that there are people and other thinking creatures, who have mental capacities. Our next step should be to say something about these capacities.

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.

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.
