Epictetus
Enchiridion 45
Somebody is hasty about bathing; do not say that he bathes badly, but that he is hasty about bathing. Somebody drinks a good deal of wine; do not say that he drinks badly, but that he drinks a good deal. For until you have decided what judgement prompts him, how do you know that what he is doing is bad? And thus the final result will not be that you receive convincing sense-impressions of some things, but give your assent to others.
Epictetus, Enchiridion 45, translated by W. A. Oldfather
Does a man bathe quickly (early)? do not say that he bathes badly, but that he bathes quickly. Does a man drink much wine? do not say that he does this badly, but say that he drinks much. For before you shall have determined the opinion, how do you know whether he is acting wrong? Thus it will not happen to you to comprehend some appearances which are capable of being comprehended, but to assent to others.
Epictetus, Enchiridion 45, translated by George Long
If a man wash quickly, do not say that he washes badly, but that he washes quickly. If a man drink much wine, do not say that he drinks badly, but that he drinks much. For till you have decided what judgement prompts him, how do you know that he acts badly? If you do as I say, you will assent to your apprehensive impressions and to none other.
Epictetus, Enchiridion 45, translated by P. E. Matheson
