Be careful to leave your sons well instructed rather than rich, for the hopes of the instructed are better than the wealth of the ignorant - Epictetus

These reasonings do not cohere: I am richer than you, therefore I am better than you; I am more eloquent than you, therefore I am better than you. On the contrary these rather cohere, I am richer than you, therefore my possessions are greater than yours: I am more eloquent than you, therefore my speech is superior to yours. But you are neither possession nor speech.
