[37] Then Cyrus asked, "And are these the only cases where one can apply the great principle of greed, or are there others?" "Oh, yes, there are many more; indeed in these simple cases any general will be sure to keep good watch, knowing how necessary it is. But your true cheat and prince of swindlers is he who can lure the enemy on and throw him off his guard, suffer himself to be pursued and get the pursuers into disorder, lead the foe into difficult ground and then attack him there. [38] Indeed, as an ardent student, you must not confine yourself to the lessons you have learnt; you must show yourself a creator and discoverer, you must invent stratagems against the foe; just as a real musician is not content with the mere elements of his art, but sets himself to compose new themes. And if in music it is the novel melody, the flower-like freshness, that wins popularity, still more in military matters it is the newest contrivance that stands the highest, for the simple reason that such will give you the best chance of outwitting your opponent. [39] And yet, my son, I must say that if you did no more than apply against human beings the devices you learnt to use against the smallest game, you would have made considerable progress in this art of overreaching. Do you not think so yourself? Why, to snare birds you would get up by night in the depth of winter and tramp off in the cold; your nets were laid before the creatures were astir, and your tracks completely covered and you actually had birds of your own, trained to serve you and decoy their kith and kin, while you yourself lay in some hiding-place, seeing yet unseen, and you had learnt by long practice to jerk in the net before the birds could fly away. [40] Or you might be out after hares, and for a hare you had two breeds of dogs, one to track her out by scent, because she feeds in the dusk and takes to her form by day, and another to cut off her escape and run her down, because she is so swift. And even if she escaped these, she did not escape you; you had all her runs by heart and knew all her hiding-places, and there you would spread your nets, so that they were scarcely to be seen, and the very haste of her flight would fling her into the snare. And to make sure of her you had men placed on the spot to keep a look-out, and pounce on her at once. And there were you at her heels, shouting and scaring her out of her wits, so that she was caught from sheer terror, and there lay your men, as you had taught them, silent and motionless in their ambuscade. [41] I say, therefore, that if you chose to act like this against human beings, you would soon have no enemies left to fight, or I am much mistaken. And even if, as well may be, the necessity should arise for you to do battle on equal terms in open field, even so, my son, there will still be power in those arts which you have studied so long and which teach you to out-villain villainy.
