Aristotle

Telle est donc la règle la meilleure, et tel est le critère le plus beau pour les biens extérieurs : qu’on soit empêché le moins possible par eux de servir et de contempler Dieu. This, therefore, is the end and the best limit regarding external things, so that the soul may be hindered as little as possible from the contemplation of God and His worship. Hic igitur finis sit et optimus terminus ad res externas respicienti, ut quam minime impediatur anima a contemplatione dei et cultu eius

For tragedy is an imitation, not of human beings, but of actions and of life.

Thus the virtues arise in us neither by nature nor against nature. Rather we are by nature able to acquire them, and reach our complete perfection through habit. p.673

And therefore, if the earlier forms of society are natural, so is the state, for it is the end of them, and the nature of a thing is its end. For what each thing is when fully developed, we call its nature, whether we are speaking of a man, a horse, or a family. Besides, the final cause and end of a thing is the best, and to be self-sufficing is the end and the best. Hence it is evident that the state is a creation of nature, and that man is by nature a political animal. (1252b30 - 1253a3)
