I fast for greater physical and mental efficiency

Do not expect justice where might is right.

This world is indeed a living being endowed with a soul and intelligence ... a single visible living entity containing all other living entities, which by their nature are all related.

Wealth and poverty; one is the parent of luxury and indolence, and the other of meanness and viciousness, and both of discontent.

All well bred men should have mastered the art of singing and dancing.

Writing is the geometry of the soul.

All soul is immortal. For that which is always in movement is immortal; that which moves something else, and is moved by something else, in ceasing from movement ceases from living. So only that which moves itself, because it does not abandon itself, never stops moving. But it is also source and first principle of movement for the other things which move.
