The Dexterity Symbolism Circuit | III
This third brain was formed when hominid types began to differentiate from other primate stock (circa 4-5 million B.C.) and is activated for the linear left-lobe functions of the brain, determines our normal modes of artifact-manufacture and conceptual thought, i.e., third circuit 'mind.'
It is no accident, then, that our logic (and our computer-design) follows either-or, binary structure of these circuits.
Nor is it an accident that our geometry, until the last century, has been Euclidean. Euclid's geometry, Aristotle's logic and Newton's physics are meta-programs synthesizing and generalizing first brain forward-back, second brain up-down and third brain right-left programs.
