Seneca

“ So, men are not encouraged by Epicurus to run riot, but the vicious hide their excesses in the lap of philosophy, and flock to the schools in which they hear the praises of pleasure. They do not consider how sober and temperate—for so, by Hercules, I believe it to be—that "pleasure" of Epicurus is, but they rush at his mere name, seeking to obtain some protection and cloak for their vices. They lose, therefore, the one virtue which their evil life possessed, that of being ashamed of doing wrong: for they praise what they used to blush at, and boast of their vices. ”

“ The pleasures of wise men, on the other hand, are mild, decorous, verging on dullness, kept under restraint and scarcely noticeable, and are neither invited to come nor received with honour when they come of their own accord, nor are they welcomed with any delight by those whom they visit, who mix them up with their lives and fill up empty spaces with them, like an amusing farce in the intervals of serious business. ”

“ Thus modesty can never reassert itself, when shameful idleness is dignified with an honourable name. The reason why that praise which your school lavishes upon pleasure is so hurtful, is because the honourable part of its teaching passes unnoticed, but the degrading part is seen by all. ”
