Perfect friendship is the friendship of men who are good, and alike in excellence; for these wish well alike to each other qua good, and they are good in themselves.
A state is an association of similar persons whose aim is the best life possible. What is best is happiness, and to be happy is an active exercise of virtue and a complete employment of it.
Humor is the only test of gravity, and gravity of humor; for a subject which will not bear raillery is suspicious, and a jest which will not bear serious examination is false wit.
Every effort therefore must be made to perpetuate prosperity. And, since that is to the advantage of the rich as well as the poor, all that accrues from the revenues should be collected into a single fund and distributed in block grants to those in need, if possible in lump sums large enough for the acquisition of a small piece of land, but if not, enough to start a business, or work in agriculture. And if that cannot be done for all, the distribution might be by tribes or some other division each in turn.

Since the whole city has one end, it is manifest that education should be one and the same for all, and that it should be public, and not private - not as at present, when every one looks after his own children separately, and gives them separate instruction of the sort which he thinks best; the training in things which are of common interest should be the same for all.

And it is clear that the rule of the soul over the body, and of the mind and the rational element over the passionate, is natural and expedient; whereas the equality of the two or the rule of the inferior is always hurtful.
