First of all, I agree that there remains much to be explained. More than we know.
>> Why are physical processes ever accompanied by experience?
My approach is perhaps a bit "stronger" than Strawson's. In response to the question above, I say physical processes just are experience.
I know that you don't see how that can be. We've rightly so hagglers over the term 'experience.' Do there need to be subjects for there to be experience, etc.
(Think of the relationship between
perception and
hallucination; they are both the 'same' from one perspective, but also different from another.)
I've tried many different ways to express my thoughts to no avail. Suffice it to say that a physical process that we would call experiential is not ontologically distinct from a physical process that is non-experiential. Both processes consist of exactly the same thing.
In my way of thinking, the fact that some physical processes are 'experiential' has to do with their phenomenal character. It's akin to the adverbial approach to perception.
Why do the physical processes of organism have the phenomenal character that they do? My thinking is along the lines of
@Pharoah 's HCT here. Although we differ on which stage phenomenal consciousness enters the picture, of course. I'm arguing that it just is physical processes, he seems to believe that it emerges from/with brain processes.
My position said differently, I would say all physical processes are phenomenal, but not all are experiential.
Why red and not green. I'm not sure. Yes, needs explaining. I'm fascinated by this question.
