Book 1
6.27
But, father, what would be the best way to gain an advantage over the enemy? By Zeus, said he, this is no easy or simple question that you ask now, my son; but, let me tell you, the man who proposes to do that must be designing and cunning, wily and deceitful, a thief and a robber, overreaching the enemy at every point. O Heracles, father, said Cyrus with a laugh, what a man you say I must become! Such, my son, he said, that you would be at the same time the most righteous and law-abiding man in the world.
6.28
Why then, pray, did you use to teach us the opposite of this when we were boys and youths? Aye, by Zeus, said he; and so we would have you still towards your friends and fellow-citizens; but, that you might be able to hurt your enemies, do you not know that you all were learning many villainies? No, indeed, father, said he; not I, at any rate. Why said he, did you learn to shoot, and why to throw the spear? Why did you learn to ensnare wild boars with nets and pitfalls, and deer with traps and toils? And why were you not used to confront lions and bears and leopards in a fair fight face to face instead of always trying to contend against them with some advantage on your side? Why, do you not know that all this is villainy and deceit and trickery and taking unfair advantage?
