§11.5.1Τίς σου ἡ τέχνη;
What is your art?
ἀγαθὸν εἶναι.
To be good.
τοῦτο δὲ πῶς καλῶς γίνεται ὴ ἐκ θεωρημάτων, τῶν μὲν περὶ τῆς τοῦ ὅλου φύσεως, τῶν δὲ περὶ τῆς ἰδίας τοῦ ἀνθρώπου κατασκευῆς.
And how is this well done except from principles, some concerning the nature of the whole, and others concerning the specific constitution of man?
