[48] 14. But as the classification of discourse is a twofold ¹ one—conversation, on the one side; oratory, on the other—there can be no doubt that of the two this debating power (for that is what we mean by eloquence) counts for more toward the attainment of glory; and yet, it is not easy to say how far an affable and courteous manner in conversation may go toward winning the affections. We have, for instance, the letters of Philip to Alexander, of Antipater to Cassander, and of Antigonus to Philip the Younger. The authors of these letters were, as we are informed, three of the wisest men in history; and in them they instruct their sons to woo the hearts of the populace to affection by words of kindness and to keep their soldiers loyal by a winning address. But the speech that is delivered in a debate before an assembly often stirs the hearts of thousands at once; for the eloquent and judicious speaker is received with high admiration, and his hearers think [p. 219] him understanding and wise beyond all others. And, if his speech have also dignity combined with moderation, he will be admired beyond all measure, especially if these qualities are found in a young man.
