Platonism

Overview

The physical world is an imperfect shadow of a higher, unchanging reality of Forms. A just life is one that turns toward those Forms.

Plato treats the things you can see and touch as unsteady. A beautiful object fades, a just act can be botched, a circle drawn in the sand is never the circle itself. Behind those changing cases he places Forms: stable patterns that the cases share. Learning, on this picture, is a turning. You stop taking the shadow for the thing.
