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.

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.

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!

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.

A real naturalistic approach, I would claim, should take the reality of mental representation as a natural fact. A lot can be said about this fact, but there is no need to say it all in terms of necessary and/or sufficient conditions which are stated in non-intentional terms. The idea that naturalism might require that all the truths should be stated in a particular kind of vocabulary now strikes me as a very peculiar one.
