M. Tullius Cicero Cum Senatui Gratias Egit 14

[14] You would think it made no difference whether you were standing in the forum with this man, or with a barbarian from Aethiopia; there he was, in that sense, without flavour, a mute, slow, uncivilized piece of goods. You would be apt to suppose him a Cappadocian just escaped out of a lot of slaves for sale. Then, again, how lustful was he at home,—how impure, how intemperate. He was not like a front-door, open for the reception of legitimate pleasures, but when he began to devote himself to literature, and, beastly rather a postern for all sorts of secret gratification. And glutton that he was, to learn philosophy with the Greeks, then he became an Epicurean, not because he was really much devoted to that sect such as it is, but because he was caught by that one expression about pleasure. And he has masters, none of those foolish fellows who go on for whole days discussing duty and virtue,—who exhort men to labour, to industry, to encounter dangers for the sake of their country, but men who argue that no hour ought to be unoccupied by pleasure; that in every part of the body there ought always to be some joy and delight to be perceived.
