Below is the conclusion to Plutarch’s On Listening. The text and translation are from the Loeb edition – Moralia v.1 pg.259 – but I think the translation rather dilutes the point.
Finally, if there be need of any other instruction in regard to listening to a lecture, it is that it is necessary to keep in mind what has here been said, and to cultivate independent thinking along with our learning, so that we may acquire a habit of mind that is not sophistic or bent on acquiring mere information, but one that is deeply ingrained and philosophic, as we may do if we believe that right listening is the beginning of right living.
Εἰ δεῖ τινος οὖν πρὸς ἀκρόασιν ἑτέρου παραγγέλματος, δεῖ καὶ τοῦ νῦν εἰρημένου μνημονεύοντας ἀσκεῖν ἅμα τῇ μαθήσει τὴν εὕρεσιν, ἵνα μὴ σοφιστικὴν ἕξιν μηδ᾿ ἱστορικὴν ἀλλ᾿ ἐνδιάθετον καὶ φιλόσοφον λαμβάνωμεν, ἀρχὴν τοῦ καλῶς βιῶναι τὸ καλῶς ἀκοῦσαι νομίζοντες.
The bolded phrase could get 20+ pages of comparanda and discussion without coming any closer to a satisfying rendering. My sense would be “so that we may acquire a mental disposition oriented not toward hair-splitting or pedantism but focused on our inner selves and in love with true wisdom.” The directive, as I read it, is to avoid the distractions of externally-oriented mental activity – wasting energy on the squabbling style of sophists and the small-minded detail focus of data inquiry – and instead turn inward for more Platonic self-cultivation.
But – because it’s never good to be too sure – here are the relevant LSJ entries (borrowed from Perseus) to offer confounding alternatives.
