"Policy is the starting-point of all the practical actions of a revolutionary party and manifests itself in the process and the end-result of that party's actions. A revolutionary party is carrying out a policy whenever it takes any action. If it is not carrying out a correct policy, it is carrying out a wrong policy; if it is not carrying out a given policy consciously, it is doing so blindly. What we call experience is the process and the end-result of carrying out a policy. Only through the practice of the people, that is, through experience, can we verify whether a policy is correct or wrong and determine to what extent it is correct or wrong. However, people's practice, especially the practice of a revolutionary party and the revolutionary masses, cannot but be bound up with one policy or another. Therefore, before any action is taken, we must explain the policy, which we have formulated in the light of the given circumstances, to Party members and to the masses. Otherwise, Party members and the masses will depart from the guidance of our policy, act blindly and carry out a wrong policy."
"Unquestionably, victory or defeat in war is determined mainly by the military, political, economic and natural conditions on both sides. However, not by these alone. It is also determined by each side's subjective ability in directing the war. In his endeavor to win a war, a military strategist cannot overstep the limitations imposed by the material conditions; within these limitations, however, he can and must strive for victory. The stage of action for a military strategist is built upon objective material conditions,
but on that stage, he can direct the performance of many a drama, full of sound and color, power and grandeur."
Um, yeah. Beta.
Lots more lengthy quotations from his 'Little Red Book'.
