The Republic

Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.

let me tell you, that the more the pleasures of the body fade away, the greater to me is the pleasure and charm of conversation.

justice is based on the idea of good, which is the harmony of the world, and is reflected both in the institutions of States and in motions of the heavenly bodies.
