Any city, however small, is in fact divided into two, one the city of the poor, the other of the rich; these are at war with one another.
PlatoTime on its back bears all things far away - Full many a challenge is wrought by many a day - Shape, fortune, name, and nature all decay
PlatoAll 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.
Plato
