Knowledge which is acquired under compulsion has no hold on... - Plato

"Life must be lived as play."

"Philosophy is the highest music."

"The soul of him who has education is whole and perfect and escapes the worst disease, but, if a man's education be neglected, he walks lamely through life and returns good for nothing to the world below."

"Ideas are the source of all things"

"You should not honor men more than truth."
