Plato's similie of the sun + others

Source: tamu.edu

 

Plato's simile of the sun, image of the divided line, and allegory of the cave are intended to clarify exactly how the things we experience in the sensible, ordinary world (e.g., chairs, drawn triangles) are less real than the ideal models (Forms) on which they rely for their existence and in terms of which they are intelligible.
