There has not been any great talent without an element of madness. -Nullum magnum ingenium sine mixtura dementiae fuit
Seneca the YoungerThe sovereign good of man is a mind that subjects all things to itself and is itself subject to nothing; such a man's pleasures are modest and reserved, and it may be a question whether he goes to heaven, or heaven comes to him; for a good man is influenced by God Himself, and has a kind of divinity within him.
