"Has it ever occurred to you, Euthydemus, ... that though pleasure is the one and only goal to which incontinence is thought to lead men, she herself cannot bring them to it, whereas nothing produces pleasure so surely as self-control?”“How so?”"Incontinence will not let them endure hunger or thirst or desire or lack of sleep, which are the sole causes of pleasure in eating and drinking and sexual indulgence, and in resting and sleeping, after a time of waiting and resistance until the moment comes when these will give the greatest possible satisfaction; and thus she prevents them from experiencing any pleasure worthy to be mentioned in the most elementary and recurrent forms of enjoyment. But self-control alone causes them to endure the sufferings I have named, and therefore she alone causes them to experience any pleasure worth mentioning in such enjoyments."
