Art of War 8.10
The Art of War (孫子兵法), Variation Of Tactics 九變篇
是故屈諸侯者以害役諸侯者以業趨諸侯者以利
Reduce the hostile chiefs by inflicting damage on them;
make trouble for them,
and keep them constantly engaged;
hold out specious allurements, and make them rush to any given point.
Lionel Giles's notes
Chia Lin enumerates several ways of inflicting this injury, some of which would only occur to the Oriental mind: — “Entice away the enemy’s best and wisest men, so that he may be left without counsellors. Introduce traitors into his country, that the government policy may be rendered futile. Foment intrigue and deceit, and thus sow dissension between the ruler and his ministers. By means of every artful contrivance, cause deterioration amongst his men and waste of his treasure. Corrupt his morals by insidious gifts leading him into excess. Disturb and unsettle his mind by presenting him with lovely women.” Chang Yü (after Wang Hsi) considers the 害 to be military chastisement: “Get the enemy,” he says, “into a position where he must suffer injury, and he will submit of his own accord.” Capt. Calthrop twists Sun Tzŭ’s words into an absurdly barbarous precept: “In reducing an enemy to submission, inflict all possible damage upon him.”
業 is defined by Ts‘ao Kung as 事, and his definition is generally adopted by the commentators. Tu Mu, however, seems to take it in the sense of “possessions,” or, as we might say, “assets,” which he considers to be 兵衆國富人和令行 “a large army, a rich exchequer, harmony amongst the soldiers, punctual fulfilment of commands.” These give us a whip-hand over the enemy.
役, literally, “make servants of them.” Tu Yu says 令不得安佚 “prevent them from having any rest.”
Mêng Shih’s note contains an excellent example of the idiomatic use of 變: 令忘變而速至 “cause them to forget pien (the reasons for acting otherwise than on their first impulse), and hasten in our direction.”
