Form I

Man cannot touch solidity. He cannot drink liquidity. To call something a solid or liquid, though, is certainly saying something both real and true of the things we experience through sensation. Notice that they have to be said of things. We must account for what we sense by using things which cannot be sensed. Not all things which exist are material.

The Heart of Plato

Plato is in many ways the father of Western philosophy. What is the most important lesson that this father has for his children?

We cannot rationally account for what the eye sees or what the hand touches without that which can neither be seen nor touched.

This is the genesis of Platonism. This is the genesis of the philosophia perennis.
