Here then we have two distinct regions or genera; one, the conceivable or intelligible, ruled by the Idea of Good--the other the visible, ruled by the Sun, which is the offspring of Good. Now let us subdivide each of these regions or genera, into two portions. The two portions of the visible will be--first, real objects, visible such as animals, plants, works of art, &c.--second, the images or representations of these, such as shadows, reflexions in water or in mirrors, &c. The first of these two subdivisions will be greatly superior in clearness to the second: it will be distinguished from the second as truth is distinguished from not-truth.[199] Matter of knowledge is in the same relation to matter of opinion, as an original to its copy. Next, the conceivable or intelligible region must be subdivided into two portions, similarly related one to the other: the first of these portions will be analogous to the real objects of vision, the second to the images or representations of these objects: the first will thus be the Forms, Ideas, or Realities of Conception or Intellect--the second will be particular images or embodiments thereof.[200] [Footnote 199: Plato, Republic, vi. pp. 509-510. 510 A: [Greek: diê|rê=sthai a)lêthei/a| te kai\ mê/, ô(s to\ doxasto\n pro\s to\ gnôsto/n, ou)/tô to\ o(moiôthe\n pro\s to\ ô(=| ô(moiô/thê.]] [Footnote 200: Plato, Republic, vi. p. 510 B.] [Side-note: To the intelligible world there are applicable two distinct modes of procedure--the Geometrical--the Dialectic. Geometrical procedure assumes diagrams.]
