§5.9.1Μὴ σικχαίνειν μηδὲ ἀπαυδᾶν μηδὲ ἀποδυσπετεῖν, εἰ μὴ καταπυκνοῦταί σοι τὸ ἀπὸ δογμάτων ὀρθῶν ἕκαστα πράσσειν, ἀλλὰ ἐκκρουσθέντα πάλιν ἐπανιέναι καὶ ἀσμενίζειν, εἰ τὰ πλείω ἀνθρωπικώτερα, καὶ φιλεῖν τοῦτο, ἐφ̓ ὃ ἐπανέρχῃ, καὶ μὴ ὡς πρὸς παιδαγωγὸν τὴν φιλοσοφίαν ἐπανιέναι, ἀλλ’ ὡς οἱ ὀφθαλμιῶντες πρὸς τὸ σπογγάριον καὶ τὸ ᾠόν, ὡς ἄλλος πρὸς κατάπλασμα, ὡς πρὸς καταιόνησιν.
Do not feel disgust, nor give up, nor despond, if it does not constantly happen to you to act in each thing from right principles; but when you have been repulsed, return again, and be content if the majority of your actions are more suited to a human being, and love this to which you return, and do not return to philosophy as to a schoolmaster, but as those with sore eyes return to the sponge and the egg, or as another to a plaster, or to a poultice.
οὕτως γὰρ οὐδὲν ἐπιδείξῃ τὸ πειθαρχεῖν τῷ λόγῳ, ἀλλὰ προσαναπαύσῃ αὐτῷ.
For in this way you will not display your obedience to reason as a show, but you will find rest in it.
μέμνησο δὲ ὅτι φιλοσοφία μόνα θέλει ἃ ἡ φύσις σου θέλει· σὺ δὲ ἄλλο ἤθελες οὐ κατὰ φύσιν.
And remember that philosophy wills only what your nature wills; but you willed something else not in accordance with nature.
τί γὰρ τούτων προσηνέστερον;
For what is more agreeable than these things?
ἡ γὰρ ἡδονὴ οὐχὶ διὰ τοῦτο σφάλλει;
For does not pleasure deceive us for this very reason?
ἀλλὰ θέασαι, εἰ προσηνέστερον μεγαλοψυχία, ἐλευθερία, ἁπλότης, εὐγνωμοσύνη, ὁσιότης, αὐτῆς γὰρ φρονήσεως τί προσηνέστερον, ὅταν τὸ ἄπταιστον καὶ εὔρουν ἐν πᾶσι τῆς παρακολουθητικῆς καὶ ἐπιστημονικῆς δυνάμεως ἐνθυμηθῇς;
But see if magnanimity, freedom, simplicity, equanimity, and holiness are not more agreeable. For what is more agreeable than wisdom itself, when you consider the unerring and prosperous course in all things of the faculty of understanding and knowledge?
