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.

There are no a priori obstacles to the scientific knowledge of the mind, but the scientific knowledge of the mind is not all the knowledge of the mind that there is. This is not an objection to science, it is just a distinction between different kinds of knowledge.

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.

Catholicism is the most philosophical branch of Christianity.

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

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.
