If these things are true; and if we are not stupid or insincere when we say that the good or ill of man lies within his own will, and that all beside is nothing to us, why are we still troubled? Why do we still fear?
Εἰ ταῦτα ἀληθῆ ἐστι καὶ μὴ βλακεύομεν μηδ᾿ ὑποκρινόμεθα ὅτι τὸ ἀγαθὸν τοῦ ἀνθρώπου ἐν προαιρέσει καὶ τὸ κακόν, τὰ δ᾿ ἄλλα πάντα οὐδὲν πρὸς ἡμᾶς, τί ἔτι ταρασσόμεθα, τί ἔτι φοβούμεθα
