I finished reading Velmas's "Evolution of Consciousness" and found it very helpful. In particular, his description of continuous and discontinuous approaches to consciousness was very helpful. I wonder how
@Pharoah would categorize HCT?
This description of the continuous approach (which is compatible with a dual-aspect/property metaphysics) is interesting:
The co-evolution of conscious experiences with their associated material forms
Continuity theorists do not face this problem for the simple reason that they do not believe that consciousness suddenly emerged at any stage of evolution. Rather, as Sherrington suggests above, consciousness is a “development of mind from unrecognisable intorecognisable.” On this panpsychist or panexperientialist view, all forms of matter have anassociated form of consciousness (see Skrbina, 2005a, b; De Quincy, 2002; Weber & Desmond,2008; Seager, 2012; Weekes, 2012). In the cosmic explosion that gave birth to the universe,consciousness co-emerged with matter and co-evolves with it. As matter became moredifferentiated and developed in complexity, consciousness became correspondinglydifferentiated and complex. The emergence of carbon-based life forms developed into creatures with sensory systems that had associated sensory “qualia.” The development of representation was accompanied by the development of consciousness that is of something.The development of self-representation was accompanied by the dawn of differentiated self-consciousness and so on. On this view, evolutionary theory can in principle account for the different forms that consciousness takes. But, consciousness, in some primal form, didnot emerge at any particular stage of evolution. Rather, it was there from the beginning. Its emergence, with the birth of the universe is neither more nor less mysterious than the emergence of matter and energy.
This approach continues to have a lot of appeal to me; it manages to address/avoid the hard problem, and it explains why experience is correlated with physical forms/processes.
It brings me back to the concept of Unbound Telesis and the Unus Mundus. And I think
@Pharoah HTC addresses this as well.
Why does energy/matter differentiate into the particular forms in which it does? (I'm in no way qualified to discuss the concept, but I think codependent origination fits here too.) Why does experience differentiate into the particular forms (qualities) which it does?
I've BSd about this as well: the forms that arise and persist in nature do so because they are self-persisting. But no form is truly self dependent; all forms are causally interconnected — or as Pharoah's might say, informed.
At its most primal level, nature has two aspects: an object, physical aspect and a subjective, experiential aspect.
As nature differentiates various physical and experiential qualities emerge.
Interestingly, this approach leads me to the noumenal problem. If phenomenal qualities co-evolve with physical qualities, a problem arises.
The boundaries between differentiated physical forms are not firm as I understand it. I could be wrong on this; however, it seems to me that physically speaking, everything in nature is really one physical process.
If phenomenal forms/qualities co-evolve with physical forms/qualities, then it would follow that boundaries between phenomenal qualities would be blurred as well. So the combination problem enters here, I think. For example, why don't my feet and brain all have minds?
If there is a continuity of experience in physical forms, why doesn't a human body—composed of billions of physical forms—have billions of minds?
How do differentiated physical forms with co-evolved/differentiated qualitative forms combine to create one unified phenomenal point of view.
I don't think this problem is insurmountable and sees easier then Chalmers hard problem.
Another thing that this approach addressed that I like, as noted in the quoted paragraph, is that experience is fundamental in nature; but the question then becomes how experience differentiates and evolves along with physical forms. This is the question I am most interested in, even more than the hard problem.
So, how does nature evolve from differentiating into the experience "green" to the experience "I am seeing green." That is, as Velman's notes above: the evolution from representation to self-representation. This I have referred to as experience and meta-experience.
