Abstract
Aristotle and the biologists who follow him have led us down a primrose path for centuries. The biological possibility of classifying species led Aristotle to assume that logic and the human mind did or should move in the same way. All men are mortal; Socrates is a man; therefore Socrates is a mortal—is true. And the human mind can also follow the universal rules of genus and species. The problem is, however, that the world was so created that human value systems do not parallel this neat structure. Not all of anything is all of something else, other than biologically or logically. Where values are concerned, God evidently opted for a dual system, one where different orders operate according to different principles. Spinoza thought all possible orders were parallel in structure. This is the rationalist’s assumption, and it would be easier for us if it were true. But God opted for greater complexity, or so it seems.
