Seneca

“ But come! let virtue lead the way: then every step will be safe. Too much pleasure is hurtful: but with virtue we need fear no excess of any kind, because moderation is contained in virtue herself. That which is injured by its own extent cannot be a good thing: besides, what better guide can there be than reason for beings endowed with a reasoning nature? ”

“ Whoever thinks that happiness consists in lazy sloth, and alternations of gluttony and profligacy, requires a good patron for a bad action, and when he has become an Epicurean, having been led to do so by the attractive name of that school, he follows, not the pleasure which he there hears spoken of, but that which he brought thither with him, and, having learned to think that his vices coincide with the maxims of that philosophy, he indulges in them no longer timidly and in dark corners, but boldly in the face of day. ”

“ He who ranges himself on the side of virtue gives thereby a proof of a noble disposition: he who follows pleasure appears to be weakly, worn out, degrading his manhood, likely to fall into infamous vices unless someone discriminates his pleasures for him, so that he may know which remain within the bounds of natural desire, which are frantic and boundless, and become all the more insatiable the more they are satisfied. ”
