§19.1περὶ μὲν οὖν τῶν ἄλλων εἰδῶν εἴρηται, λοιπὸν δὲ περὶ λέξεως καὶ διανοίας εἰπεῖν. §19.2τὰ μὲν οὖν περὶ τὴν διάνοιαν ἐν τοῖς περὶ ῥητορικῆς κείσθω· τοῦτο γὰρ ἴδιον μᾶλλον ἐκείνης τῆς μεθόδου. §19.3ἔστι δὲ κατὰ τὴν διάνοιαν ταῦτα, ὅσα ὑπὸ τοῦ λόγου δεῖ παρασκευασθῆναι. §19.4μέρη δὲ τούτων τό τε ἀποδεικνύναι καὶ τὸ λύειν καὶ τὸ πάθη παρασκευάζειν (οἷον ἔλεον ἢ φόβον ἢ ὀργὴν καὶ ὅσα τοιαῦτα) καὶ ἔτι μέγεθος καὶ μικρότητας. §19.5δῆλον δὲ ὅτι καὶ ἐν τοῖς πράγμασιν ἀπὸ τῶν αὐτῶν ἰδεῶν δεῖ χρῆσθαι ὅταν ἢ ἐλεεινὰ ἢ δεινὰ ἢ μεγάλα ἢ εἰκότα δέῃ παρασκευάζειν· §19.6πλὴν τοσοῦτον διαφέρει, ὅτι τὰ μὲν δεῖ φαίνεσθαι ἄνευ διδασκαλίας, τὰ δὲ ἐν τῷ λόγῳ ὑπὸ τοῦ λέγοντος παρασκευάζεσθαι καὶ παρὰ τὸν λόγον γίγνεσθαι.
Now concerning the other kinds enough has been said; it remains to speak of diction and thought. Let the matters concerning thought, then, be laid down in the treatise on Rhetoric; for this is indeed more proper to that inquiry. And under thought fall all those effects that must be produced by speech. The parts of these are demonstration, refutation, the producing of emotions (such as pity, fear, anger, and the like), and further, exaggeration and depreciation. It is evident that in the dramatic actions as well, one must use the same forms of thought whenever it is necessary to produce effects of pity, terror, importance, or probability. There is only this much difference, that the actions must appear to have these qualities without explicit explanation, whereas the latter must be produced in the speech by the speaker and arise from the speech.
τί γὰρ ἂν εἴη τοῦ λέγοντος ἔργον, εἰ φαίνοιτο ᾗ δέοι καὶ μὴ διὰ τὸν λόγον; §19.7τῶν δὲ περὶ τὴν λέξιν ἓν μέν ἐστιν εἶδος θεωρίας τὰ σχήματα τῆς λέξεως, ἅ ἐστιν εἰδέναι τῆς ὑποκριτικῆς καὶ τοῦ τὴν τοιαύτην ἔχοντος ἀρχιτεκτονικήν, οἷον τί ἐντολὴ καὶ τί εὐχὴ καὶ διήγησις καὶ ἀπειλὴ καὶ ἐρώτησις καὶ ἀπόκρισις καὶ εἴ τι ἄλλο τοιοῦτον.
For what would be the function of the speaker if things should appear in the required light even without the speech? As regards diction, one subject of inquiry is the modes of expression, the knowledge of which belongs to the art of delivery and to him who possesses this master-art—such as, what is a command, a prayer, a narrative, a threat, a question, an answer, and so forth. For no criticism is brought against the poetic art based on the knowledge or ignorance of these things that is at all worthy of serious attention.
§19.8παρὰ γὰρ τὴν τούτων γνῶσιν ἢ ἄγνοιαν οὐδὲν εἰς τὴν ποιητικὴν ἐπιτίμημα φέρεται ὅ τι καὶ ἄξιον σπουδῆς. τί γὰρ ἄν τις ὑπολάβοι ἡμαρτῆσθαι ἃ Πρωταγόρας ἐπιτιμᾷ, ὅτι εὔχεσθαι οἰόμενος ἐπιτάττει εἰπὼν
μῆνιν ἄειδε θεά;
For why should anyone regard as an error what Protagoras criticizes—that, thinking to pray, he actually commands when he says, 'Sing, goddess, the wrath'?
τὸ γὰρ κελεῦσαι, φησίν, ποιεῖν τι ἢ μὴ ἐπίταξίς ἐστιν. §19.9διὸ παρείσθω ὡς ἄλλης καὶ οὐ τῆς ποιητικῆς ὂν θεώρημα.
For to order someone to do or not to do something, he says, is a command. Therefore, let this subject be passed over as belonging to another art and not to poetics.
