Problems come and go over time, and to understand why is a difficult historical task. If one wanted to find the origin of a problem, historical research and close attention to texts is what is needed, not unconstrained speculation about the 'pictures' that philosophers must be in the grip of.

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.

I do think that if you are trying to think empirically about the relationship between conscious experience and the underlying physical reality, wine provides an excellent practical example. Winemakers manipulate the chemicals they are dealing with in a way that is very sensitive to the kinds of effects it will have on the subjective experience of tasters - this is not an accident.

I like to think of myself as a naturalist - insofar as that term is at all clear.

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.

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.
