Aristotle, Eudemian Ethics 1247b
“If certain people are good natured—just as some musical people who do not know how to sing yet are still born for it—and without any logical training are inclined towards basic nature and desire what is right in the time and way that is right, such people will find success even if they are really irrational fools just as some people may sing well even though they don’t know how to teach it. People who are generally successful without thinking about it are lucky like this. Based on this, we can say they are lucky by nature.”
εἰ δή τινές εἰσιν εὐφυεῖς (ὥσπερ οἱ ᾠδικοὶ οὐκ ἐπιστάμενοι ᾄδειν οὕτως εὖ πεφύκασι) καὶ ἄνευ λόγου ὁρμῶσιν ᾗ ἡ φύσις πέφυκε καὶ ἐπιθυμοῦσι καὶ τούτου καὶ τότε καὶ οὕτως ὡς δεῖ καὶ οὗ δεῖ καὶ ὅτε, οὗτοι κατορθώσουσι κἂν τύχωσιν ἄφρονες ὄντες καὶ ἄλογοι, ὥσπερ καὶ εὖ ᾄσονται οὐ διδασκαλικοὶ ὄντες. οἱ δέ γε τοιοῦτοι εὐτυχεῖς, ὅσοι ἄνευ λόγου κατορθοῦσιν ὡς ἐπὶ τὸ πολύ. φύσει ἄρα οἱ εὐτυχεῖς εἶεν ἄν.
