We are a skeptical lot and with good reason.
When you first introduced HCT, I recall reading through that first paper with great interest and hope. Only to find that you hadn't addressed (phenomenal) consciousness at all.
When this was brought to your attention, I recall you commenting that you would "shred Chalmers."
You
seem to have moved on from that stance and now embrace Strong Emergentism. I say seem to have because as I read your arguments, I find that the how, why, and when of phenomenal consciousness still has not been addressed.
You have a clever, compelling story about organisms/species evolving "subjective" relationships with the environment.
You describe these organisms and their relationships using terms such as "qualitative" and "meaningful" and "subjective" but you haven't established a case for how, why, and when
the organisms themselves might come to possess a phenomenal, unified, mental perspective of the world. (Which is why I claim that you are using the intentional stance.)
Any theory, such as yours, which begins with the assumption of an insentient background, will be at pains to resolve the following problems:
The emergence of sentience from insentience (mental from matter)
Overdetermination
Downward causation
The unity of subjective experience
Also, regarding skepticism, when I have argued for non-materialist physicalism,
@smcder and
@Constance have asked me to address all the same problems that smcder and I have asked you/HCT to address.
Sometimes I ask questions seeking to understand how HCT addresses one of the above problems; sometimes I ask to point out that HCT fails to address the above problems.
