ἀγωνιστὰς...λόγ. ποιητάς ‘It cannot make them good debaters or masterly orators, but it can improve their natural power, and in many respects sharpen their insight’. — ἀγωνιστής, a combatant in real debate, opposed to a mere student or declaimer. Cleon's speech in Thuc. III. 37, 38 brings out this image of debate as an ἀγών: , I. 39.
