Xenophon on the Use of Force

Compulsion is not the method of him who makes wisdom his study, but of him who wields power untempered by reflection. Once more: the man who ventures on violence needs the support of many to fight his battles, while he whose strength lies in persuasiveness triumphs single-handed, for he is conscious of a cunning to compel consent unaided. And what has such a one to do with the spilling of blood? since how ridiculous it were to do men to death rather than turn to account the trusty service of the living.
