Friendship is a single soul dwelling in two bodies.

- Aristotle -

Aristotle (384–322 BC) was Plato's student and Alexander the Great's tutor, and founded the Lyceum in Athens. His work spans logic, biology, ethics, politics, rhetoric and poetics — effectively the whole of the knowledge available to him. The Nicomachean Ethics, where he develops virtue as a mean between extremes, is still read as a living text.

About this theme: Friendship

Aristotle gave friendship two books of the Nicomachean Ethics, more than he gave justice, and distinguished three kinds: friendship for use, for pleasure, and for the friend's own sake. The first two last as long as the reason lasts; the third is rare and slow, and the only one he considered complete.
