A quote
“Who said this?” you ask, as if you were ignorant whom I am pressing into service; it is Epicurus. But this same watchword rings in your ears from every sect,—Peripatetic, Academic, Stoic, Cynic. For who that is pleased by virtue can please the crowd? It takes trickery to win popular approval; and you must needs make yourself like unto them; they will withhold their approval if they do not recognize you as one of themselves. However, what you think of yourself is much more to the point than what others think of you. The favour of ignoble men can be won only by ignoble means.
