Aristotle, Nicomachean Ethics 7.7-9
“Certainly those who are overcome by emotions are predisposed in this way. For their rages and desires for sex and other types of enticements obviously transform the body too and creates madness in some. Hence, we must call those who are like this the same as those who are uncontrolled.
For being about to speak words is not at all a sign of understanding. For people who are in these states of mind often recite proofs and the verses of Empedocles. But people who have just learned something will repeat the words when they don’t yet understand them. For knowledge needs to be integrated and this requires time. So, those who talk when they are uncontrolled must be considered as if they were actors reciting their lines.”
ἀλλὰ μὴν οὕτω διατίθενται οἱ ἐν τοῖς πάθεσιν ὄντες· θυμοὶ γὰρ καὶ ἐπιθυμίαι ἀφροδισίων καὶ ἔνια τῶν τοιούτων ἐπιδήλως καὶ τὸ σῶμα μεθιστᾶσιν, ἐνίοις δὲ καὶ μανίας ποιοῦσιν. δῆλον οὖν ὅτι ὁμοίως ἔχειν λεκτέον τοὺς ἀκρατεῖς τούτοις. τὸ δὲ λέγειν τοὺς λόγους τοὺς ἀπὸ τῆς ἐπιστήμης οὐδὲν σημεῖον· καὶ γὰρ οἱ ἐν τοῖς πάθεσι τούτοις ὄντες ἀποδείξεις καὶ ἔπη λέγουσιν Ἐμπεδοκλέους, καὶ οἱ πρῶτον μαθόντες συνείρουσι μὲν τοὺς λόγους, ἴσασι δ᾿ οὔπω· δεῖ γὰρ συμφυῆναι, τοῦτο δὲ χρόνου δεῖται· ὥστε καθάπερ τοὺς ὑποκρινομένους, οὕτως ὑποληπτέον λέγειν καὶ τοὺς ἀκρατευομένους.
