He who is gracious to his lover under the impression that he is rich, and is disappointed of his gains because he turns out to be poor, is disgraced all the same: for he has done his best to show that he would give himself up to any one's "uses base" for the sake of money; but this is not honourable.
PlatoWhen there is an income tax, the just man will pay more and the unjust less on the same amount of income.
PlatoTrue opinions are a fine thing and do all sorts of good so long as they stay in their place; but they will not stay long. They run away from a man's mind, so they are not worth much until you tether them by working out the reason. Once they are tied down, they become knowledge, and are stable.
Plato
