Note (return) — Chapter X

According to the scheme of Plato, these two general divisions of the mental powers are capable of a further subdivision. He says: Consider that there are two kinds of things, the intelligible and the visible; two different regions, the intelligible world and the sensible world. Now take a line divided into two equal segments to represent these two regions, and again divide each segment in the same ratio--both that of the visible and that of the intelligible species. The parts of each segment are to represent differences of clearness and indistinctness. In the visible world the parts are things and images. By images I mean shadows, 530 reflections in water and in polished bodies, and all such like representations; and by things I mean that of which images are resemblances, as animals, plants, and things made by man.
