Epictetus, Encheiridion, 48
“The state and character of an ‘idiot’ is this: he never expects harm or help from himself, but he always looks elsewhere. This is the state and character of a philosopher: he expects all help and harm to come from himself
These are signs of someone making progress: he blames no one; praises no one; criticizes no one; impugns no one; and says nothing about himself as if he were someone or knew something. Whenever he meets an obstacle or is held back, he takes the blame. Whenever anyone praises him, he chuckles to himself while they praise. If someone criticizes him, he offers no defense. He proceeds just like the feeble, taking care not to disturb anything he is developing before it grows firm.
He has banished every desire from himself and he has admitted to disinclination only those aspects of nature which are under our control, He applies a disinterested impulse toward all things. Should he seem to be simple or unlearned, he doesn’t care. In sum, he guards against himself as if he were an enemy conspirator.”
48. Ἰδιώτου στάσις καὶ χαρακτήρ· οὐδέποτε ἐξ ἑαυτοῦ προσδοκᾷ ὠφέλειαν ἢ βλάβην, ἀλλ᾿ ἀπὸ τῶν ἔξω. φιλοσόφου στάσις καὶ χαρακτήρ· πᾶσαν ὠφέλειαν καὶ βλάβην ἐξ ἑαυτοῦ προσδοκᾷ.
Σημεῖα προκόπτοντος· οὐδένα ψέγει, οὐδένα ἐπαινεῖ, οὐδένα μέμφεται, οὐδενὶ ἐγκαλεῖ, οὐδὲν περὶ ἑαυτοῦ λέγει ὡς ὄντος τινὸς ἢ εἰδότος τι. ὅταν ἐμποδισθῇ τι ἢ κωλυθῇ, ἑαυτῷ ἐγκαλεῖ. κἄν τις αὐτὸν ἐπαινῇ, καταγελᾷ τοῦ ἐπαινοῦντος αὐτὸς παρ᾿ ἑαυτῷ· κἂν ψέγῃ, οὐκ ἀπολογεῖται. περίεισι δὲ καθάπερ οἱ ἄρρωστοι, εὐλαβούμενός τι κινῆσαι τῶν καθισταμένων, πρὶν πῆξιν λαβεῖν.
ὄρεξιν ἅπασαν ἦρκεν ἐξ ἑαυτοῦ· τὴν δ᾿ ἔκκλισιν εἰς μόνα τὰ παρὰ φύσιν τῶν ἐφ᾿ ἡμῖν μετατέθεικεν. ὁρμῇ πρὸς ἅπαντα ἀνειμένῃ χρῆται. ἂν ἠλίθιος ἢ ἀμαθὴς δοκῇ, οὐ πεφρόντικεν. ἑνί τε λόγῳ, ὡς ἐχθρὸν ἑαυτὸν παραφυλάσσει καὶ ἐπίβουλον.
