If what the philosophers say be true,—that all men's actions proceed from one source; that as they assent from a persuasion that a thing is so, and dissent from a persuasion that it is not, and suspend their judgment from a persuasion that it is uncertain,—so likewise they seek a thing from a persuasion that it is for their advantage.
Εἰ ἀληθές ἐστι τὸ ὑπὸ τῶν φιλοσόφων λεγόμενον ὅτι πᾶσιν ἀνθρώποις μία ἀρχὴ καθάπερ τοῦ συγκαταθέσθαι τὸ παθεῖν ὅτι ὑπάρχει καὶ τοῦ ἀνανεῦσαι τὸ παθεῖν ὅτι οὐχ ὑπάρχει καὶ νὴ Δία τοῦ ἐπισχεῖν τὸ παθεῖν ὅτι ἄδηλόν ἐστιν, οὕτως καὶ τοῦ ὁρμῆσαι ἐπί ⟨τι⟩ τὸ παθεῖν ὅτι ἐμοὶ συμφέρει.
