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.
PlatoFor the man who makes everything that leads to happiness, or near to it, to depend upon himself, and not upon other men, on whose good or evil actions his own doings are compelled to hinge,--such a one, I say, has adopted the very best plan for living happily. This is the man of moderation; this is the man of manly character and of wisdom.
Plato
