...the understanding of any person is an exercise in genealogy. A man is not a static organism to be taken apart and analyzed and classified. A man is movement, motion, a continuum. There is no beginning to him. He runs through his ancestors, and the only beginning is the primal beginning of the single cell in the slime. The proper study of mankind is man, but man is an endless curve on the eternal graph paper, and who can see the whole curve?
