In this paper, we approach "war and peace" in terms of the philosophy of war from the perspective of soldiers' life experience. And we look at one's experience in terms of the three fundamental principles-cultivating wisdom, finding the truth and validating the value-in order to generalize all the ideas about war and peace that we understand. First, we basically see war as "necessary evil." Then the writer makes norms about war and sorts out more than thirty years of learning and understanding in war consciousness to state military attributes, fundamental beliefs, codes of conduct, and military ethics. Besides, the writer combines the war consciousness with the rapid-developing knowledge-based military-rationalization, globalization, education, informationalization-so as to be connected to soldier's basic concept "prepare for war to stop war and understand war to maintain peace." Then we return to the one and only war philosophy that argues for the cease of war-Chinese war philosophy. Starting with the military principle of "Dao," the spirit of Tai-Chi, military science, we further focus on the source of Chinese military thoughts, "Ji," as the counterpart of the western technology-based thoughts about war. We look at the "judgment about consciousness and military conditions," analyze the implications of "Ji," point out its relation with the military command, in wishes to show that war commanders are still non-instrumental. We conclude that non-Ji war means exactly nonsense.
