Paranormal Adept
I'm not sure about this, actually. As I noted in a past post, I think qualia can actually be arbitrary. That is, you could perceive an apple pie as green velveeta so long as you always perceived it that way.if you have property dualism you have to account for both sides of the puzzle, as the neurons are put together into a brain, phenomenal experience (carried as a property of the primal stuff the neurons themselves are made of) has to also be put together and in a coherent way so that our subjective impression of the world is accurate ... so subjective experience, the mental, constrains the formation of the nervous system as much as vice versa and both have to be functional and point to the same thing, I won't survive if I perceive that apple pie as green velveeta.
This may be an area ripe for phenomenological study, but it seems that many qualia (at first blush) could be arbitrary: taste, color, sound, even feelings. Why couldn't pain by pleasure and pleasure be pain.
On the other hand, at first blush, certain qualia strike me as being essential such as size and distance. Meaning, it wouldn't matter if a tiger was purple and smelled like roses, but if we perceived it as being far away when it was actually close, that might be a problem. (On second thought, we would just "learn" that when a tiger was "far away," that meant danger...)
Again, I haven't devoted much thought to this, but I'm not sure how much phenomenal experience constrains the material side of the coin, at least a priori (if I'm using that correctly).
However, once the physical puzzle started to come together - producing the subjective puzzle - the subjective puzzle couldn't all of the sudden go higgly piggly. If the subjective puzzle went bonkers, that would indicate that the physical puzzle was going bonkers too.
