“It appears that all units of reality are comprised of two basic elements in an asymmetrical binary relationship in dynamic interaction…” (p.38) “As noted above, one of the basic ideas that underlies my thinking, one of the images I have in mind when I contemplate the universe, is that it is constructed upon a simple pattern of order that may be seen in any and all phenomena, no matter how complex. The simple pattern is that of a binary relationship, recognized in a binary system. The implication here is that everything in nature, everything in the universe, is composed of networks of two elements, or two parts in functional relationship to each other…”(p.39) “The most fundamental phenomenon in the universe is relationship.”(p.44)
