Enchiridion · §45

ταχέως λούεταί τις; μὴ λέγε ὅτι κακῶς, ἀλλ᾽ ὅτι ταχέως. πολὺ πίνει τις; μὴ λέγε ὅτι κακῶς, ἀλλ᾽ ὅτι πολύ. πρὶν γὰρ διαγνῶναι τὸ δόγμα, πόθεν οἶδας εἰ κακῶς; οὕτως οὐ συμβήσεταί σοι ἄλλων μὲν φαντασίας καταλαμβάνειν, ἄλλοις δὲ συγκατατίθεσθαι.

tacheōs louetai tis? mē lege hoti kakōs, all' hoti tacheōs. polu pinei tis? mē lege hoti kakōs, all' hoti polu. prin gar diagnōnai to dogma, pothen oidas ei kakōs?

Does someone bathe quickly? Do not say they bathe badly — say they bathe quickly. Does someone drink a lot? Do not say they drink badly — say they drink a lot. Until you understand their judgment, how can you know whether it is bad? In this way you will not find yourself perceiving impressions of others falsely while assenting to them as if they were true.
