The biological development of consciousness is, in my opinion, still a good avenue for research; but I don't pretend to know any answers there. I may have something to say about the "free will" issue, if time permits (and if I'm not predetermined to ignore it).
I'm dazzled by the effort you've put into this. [Enthusiastic smooches!]
(Now ... where did I put those stackers???)
I got into the Plato/Aristotle debate because, laying the Intelligent Design Movement aside, IMHO it lies at the root of what the mathematicians and physicists are bringing to "the table."
As to the beginnings, well, I guess you are right - I am philosophically audacious - but it seemed appropriate to connect the thoughts.
