ON PLATO’S DIVIDED LINE ANALOGY AND OPTICS
Abstract
Plato, in his discussion about the education of philosophers that will govern the Polis in the last section of Republic Book VI, in order to illustrate that ‘good’ belongs to the intelligible world, divides the world into two pieces as the sensible world and the conceivable world. In this analogy known as the Divided Line Analogy, these pieces should be in different lengths. Afterwards these pieces at hand are divided in the same ratio so that four pieces are formed on the line. These pieces, from smallest to the largest, are called as eikasia, pistis, dianoia and noesis respectively. Divided Line Analogy, on the one hand, displays the (ontological) hierarchy that Plato demands to construct among the beings, on the other hand displays the (epistemic) distinction made between the various kinds and degrees of knowledge that are adequate to this hierarchy. Certain ratios that are expressed in dividing the line contributes to this hierarchy. These ratios imply that knowledge of mathematics or geometry has been considered in description of the analogy. Especially, two pieces at the middle of the line are necessarily equal in length mathematically. In this paper, the meanings of this equality will be discussed by emphasizing a comment about optics.
