Eidos
What indeed does Socrates say when Cebes and Simmias ask him to provide them with a magician? He urges them to practice the philosophic dialogue and seek its most worthy object: the truth of the eidos as that which is identical to itself, always the same as itself and therefore simple, incomposite (asuntheon), undecomposable, invariable. The eidos is that which can always be repeated as the same.
