Is this, your understanding of HCT, still the case @Constance?
"In the earliest awakenings of consciousness in the primordial organism, it feels that it is ‘there’ without understanding what or where ‘there’ is. That is a kind of yet-inchoate knowledge that we have yet to recognize as real and productive in the development of consciousness and mind."
Yes. As I've said all along in commenting on versions of your HCT theory expressed in the series of papers you've linked, your theory fails to account for the prereflective experience {protoconsciousness} recognized in phenomenological philosophy. As Steve has indicated in his last several posts we have Jaak Panksepp and his Affective Neuroscience research to thank for biological and evolutionary insight into prereflective experience as understood in phenomenology. Consciousness proper develops from that which grounds it in protoconscious prereflective experience in the world. Maturana and Varela's profoundly significant biological discovery of autopoesis in the primordial single-celled organism became possible on the basis of their reading phenomenological philosophy, particularly the works of Merleau-Ponty. One needs to read Maturana, Varela, Panksepp, and the phenomenological philosophers in order to comprehend what prereflective 'knowing' is, exemplified both in the evolution of species and in the developmental nature of experienced being and consciousness in human infants and children.
A final comment, which might seem harsh but is valid: the interdisciplinary field of Consciousness Studies has been spearheaded by philosophers of two different schools, analytical (sharing the materialist/objectivist presuppositions of the still-dominant scientific paradigm) and phenomenologists, who examine experience more deeply. To attempt to make contributions to the understanding of consciousness, one needs to be familiar with both schools or else one is playing with only half a deck.
