Epictetus, Treatises Collected by Arrian, 2.15: To those who cling to any judgments they have made tenaciously
“Whenever some men hear these words—that it is right to be consistent, that the moral man is free by nature and never compelled, while everything else may be hindered, forced, enslaved, subjected to others—they imagine that it is right that they maintain every judgment they have made without compromising at all. But the first issue is that the judgment should be a good one. For, if I wish to maintain the state of my body, it should be when it is healthy, well-exercised. If you show me that you have the tone of a crazy person and brag about it, I will say ‘Man, look for a therapist. This is not health, but sickness.’ “
ιε′. Πρὸς τοὺς σκληρῶς τισιν ὧν ἔκριναν ἐμμένοντας.
῞Οταν ἀκούσωσί τινες τούτων τῶν λόγων, ὅτι βέβαιον εἶναι δεῖ καὶ ἡ μὲν προαίρεσις ἐλεύθερον φύσει καὶ ἀνανάγκαστον, τὰ δ’ ἄλλα κωλυτά, ἀναγκαστά, δοῦλα, ἀλλότρια, φαντάζονται ὅτι δεῖ παντὶ τῷ κριθέντι ὑπ’ αὐτῶν ἀπαραβάτως ἐμμένειν. ἀλλὰ πρῶτον ὑγιὲς εἶναι δεῖ τὸ κεκριμένον. θέλω γὰρ εἶναι τόνους ἐν σώματι, ἀλλ’ ὡς ὑγιαίνοντι, ὡς ἀθλοῦντι· ἂν δέ μοι φρενιτικοῦ τόνους ἔχων ἐνδεικνύῃ[ς] καὶ ἀλαζονεύῃ ἐπ’ αὐτοῖς, ἐρῶ σοι ὅτι ‘ἄνθρωπε, ζήτει τὸν θεραπεύσοντα. τοῦτο οὐκ εἰσὶ τόνοι, ἀλλ’ ἀτονία’.
