Rhetoric Section 1

ἐκ τίνων μὲν οὖν δεῖ καὶ προτρέπειν καὶ ἀποτρέπειν, καὶ ἐπαινεῖν καὶ ψέγειν, καὶ κατηγορεῖν καὶ ἀπολογεῖσθαι, καὶ ποῖαι δόξαι καὶ προτάσεις χρήσιμοι πρὸς τὰς τούτων πίστεις, ταῦτʼ ἐστίν· περὶ γὰρ τούτων καὶ ἐκ τούτων τὰ ἐνθυμήματα, ὡς περὶ ἕκαστον εἰπεῖν ἰδίᾳ τὸ γένος τῶν λόγων.

Such then are the materials which we must employ in exhorting and dissuading, praising and blaming, accusing and defending, and such are the opinions and propositions that are useful to produce conviction in these circumstances; for they are the subject and source of enthymemes, which are specially suitable to each class (so to say) of speeches.

Telles sont donc les matières que nous devons employer pour exhorter et dissuader, louer et blâmer, accuser et défendre ; telles sont aussi les opinions et les propositions utiles pour produire la conviction dans ces circonstances. Car elles constituent le sujet et la source des enthymèmes qui conviennent spécialement à chaque classe, pour ainsi dire, de discours.
