 Without a strong military to defend the just, he believed that Confucian virtues would disappear, and evil would dominate the world.Because of his emphasis on the importance of the military for safeguarding civil rights and liberty, the author of the "Wuzi" states that commanders must be selected carefully, ideally from those possessing courage and who excelled in military arts, but who also possessed good civil administration skills, and who displayed Confucian virtues, particularly those of wisdom and self-control.Because armies in the Warring States were heavily dependent on the horse, both for transportation and for the power of the chariot, the "Wuzi" places a greater importance and focus on raising and maintaining a force of cavalry more than on maintaining infantry in its discussions of logistics.
