The boys were also taught to use a discourse which combined pungency with grace, and condensed much observation into a few words. His iron money, indeed, Lycurgus made of large weight and small value, as I have observed, Chapter ix. 1. but the current coin of discourse he adapted to the expression of deep and abundant meaning with simple and brief diction, by contriving that the general habit of silence should make the boys sententious and correct in their answers. For as sexual incontinence generally produces unfruitfulness and sterility, so intemperance in talking makes discourse empty and vapid. King Agis, accordingly, when a certain Athenian decried the Spartan swords for being so short, and said that jugglers on the stage easily swallowed them, replied: And yet we certainly reach our enemies with these daggers. And I observe that although the speech also of the Spartans seems short, yet it certainly reaches the point, and arrests the thought of the listener.
