As for Wisdom, the greatest blessing, does not incontinence exclude it and drive men to the opposite? Or don’t you think that incontinence prevents them from attending to useful things and understanding them, by drawing them away to things pleasant, and often so stuns their perception of good and evil that they choose the worse instead of the better?That does happen.

With Prudence, Euthydemus, who, shall we say, has less to do than the incontinent? For I presume that the actions prompted by prudence and incontinence are exact opposites?I agree with that too.To caring for what is right is there any stronger hindrance, do you think, than incontinence?Indeed I do not.And do you think there can be aught worse for a man than that which causes him to choose the harmful rather than the useful, and persuades him to care for the one and to be careless of the other, and forces him to do the opposite of what prudence dictates?Nothing.
