Plutarch, On The Tranquility of Mind, 467 C-D
“Thoughtful men–just a bees have find honey in thyme, the most bitter and driest plants–extract something fitting and useful to themselves even from the most adverse situations.
It is necessary that we practice and take care of this first, like the man who missed a dog with a stone but struck his step-mother instead and said “That’s not so bad”. For it is possible to change our reception of chance from undesired outcomes. Diogenes was sent into exile? “That’s not so bad!” For he began to become a philosopher after his exile.”
οἱ δὲ φρόνιμοι, καθάπερ ταῖς μελίτταις μέλι φέρει τὸ δριμύτατον καὶ ξηρότατον ὁ θύμος, οὕτως ἀπὸ τῶν δυσχερεστάτων πολλάκις πραγμάτων οἰκεῖόν τι καὶ χρήσιμον αὑτοῖς λαμβάνουσι.
Τοῦτ’ οὖν δεῖ πρῶτον ἀσκεῖν καὶ μελετᾶν, ὥσπερ ὁ τῆς κυνὸς ἁμαρτὼν τῷ λίθῳ καὶ τὴν μητρυιὰν πατάξας ‘οὐδ’ οὕτως’ ἔφη ‘κακῶς•’ ἔξεστι γὰρ μεθιστάναι τὴν τύχην ἐκ τῶν ἀβουλήτων. ἐφυγαδεύθη Διογένης• ‘οὐδ’ οὕτως κακῶς’• ἤρξατο γὰρ φιλοσοφεῖν μετὰ τὴν φυγήν.
