I would rather excel in the knowledge of what is excellent than the extent of my power or possessions. - Plutarch

Democritus urges us to seek out labor, which is a source of great and glorious things for men.

Being about to pitch his camp in a likely place, and hearing there was no hay to be had for the cattle, "What a life," said he, "is ours, since we must live according to the convenience of asses!"

For there is no virtue, the honour and credit for which procures a man more odium than that of justice; and this, because more than any other, it acquires a man power and authority among the common people. For they only honour the valiant and admire the wise, while in addition they also love just men, and put entire trust and confidence in them. They fear the bold man, and mistrust the clever man, and moreover think them rather beholding to their natural complexion, than to any goodness of their will, for these excellences; they look upon valour as a certain natural strength of the mind, and wisdom as a constitutional acuteness; whereas a man has it in his power to be just, if he have but the will to be so, and therefore injustice is thought the most dishonourable, because it is least excusable.
