for a man does the opposite of what he judges, owing to incontinence, but judges what is good to be evil and something that he should not do, and consequence he will do what is good and not what is evil.

Context

“(for thought is bound fast when it will not rest because the conclusion does not satisfy it, and cannot advance because it cannot refute the argument) . There is an argument from which it follows that folly coupled with incontinence is virtue; for a man does the opposite of what he judges, owing to incontinence, but judges what is good to be evil and something that he should not do, and consequence he will do what is good and not what is evil. (5) Further, he who on conviction does and pursues and chooses what is pleasant would be thought to be better than one who does so as a result not of calculation but of incontinence; for he is easier to cure since he may be persuaded to change his mind.” source
