Military Science of Sun Tzu and the Development of Military Ethics in the period of Pre-Qin Dynasty

Although Military Science of Sima was completed a bit late,some contents concerning retrospecting and studying military science of Sima Rangju in the sight of the existing books on military science present the humanitarianism in ancient military domain.In light of rational ideological trend,Military Science of Sun Tzu held that soldiers should seek to stabilize his kingdom and bring benefits to his King,benefit should be basic and prior value in the war and actions should be taken in favorable condition and stopped in unfavorable situation.Military Science of Sun Tzu can not reflect ancient benevolent doctrine.Its standpoint is different from the Confucian's and belongs to sovereign or kingdom standard.The development of military ethics in the period of pre-Qin Dynasty experienced a gradual U-typed progress,such as the development from Military Science of Sima to Military of Sun Tzu is from the top down and from Military Science of Sun Tzu to Military Science of Wei Liao Zi is rising to emphasize military ethics again.Military Science of Sun Tzu should not be depreciated in ethics,because Sun Tzu is not a politician and social theorist and military science and ethics belongs to different domains with different research objects.Since the ethical confusion can be setting aside in Military Science of Sun Tzu,a brilliant military science system with eastern characteristics can be created.
