Experience involves both structure and process. Too often theories of knowledge emphasize the nature of knowledge as primarily structural. But knowing is a part of living and living is essentially processual. The intention here is to give equal emphasis to structure and process, according to different claims : – intuition is essential to knowing because it is omnipresent in awareness of appearance; – mind is substantial, it remains through change and functions substantially in many mental ways; – mind and body are not merely interdependent but are also mutually immanent; – mind-body mutual immanence results from “ontogeny recapitulates phylogeny”; – all reasoning is analogical, strict logic is located at the sameness end of the sameness-difference range. – Chapter 1, Intuition : A.
