As for the members of the reactionary classes and individual reactionaries, so long as they do not rebel, sabotage or create trouble after their poli… - Mao Zedong

"I am not sure I can handle it." We often hear this remark when a comrade hesitates to accept an assignment. Why is he unsure of himself? Because he has no systematic understanding of the content and circumstances of the assignment, or because he has had little or no contact with such work, and so the laws governing it are beyond him. After a detailed analysis of the nature and circumstances of the assignment, he will feel more sure of himself and do it willingly. If he spends some time at the job and gains experience and if he is a person who is willing to look into matters with an open mind and not one who approaches problems subjectively, one-sidedly and superficially, then he can draw conclusions for himself as to how to go about the job and do it with much more courage. Only those who are subjective, one-sided and superficial in their approach to problems will smugly issue orders or directives the moment they arrive on the scene, without considering the circumstances, without viewing things in their totality (their history and their present state as a whole) and without getting to the essence of things (their nature and the internal relations between one thing and another). Such people are bound to trip and fall.

和形而上学的宇宙观相反，唯物辩证法的宇宙观主张从事物的内部、从一事物对他事物的关系去研究事物的发展，即把事物的发展看做是事物内部的必然的自己的运动，而每一事物的运动都和它的周围其它事物互相联系着和互相影响着。事物发展的根本原因，不是在事物的外部而是在事物的内部，在于事物内部的矛盾性。任何事物内部都有这种矛盾性，因此引起了事物的运动和发展。事物内部的这种矛盾性是事物发展的根本原因，一事物和他事物的互相联系和互相影响则是事物发展的第二位的原因。这样，唯物辩证法就有力地反对了形而上学的机械唯物论和庸俗进化论的外因论或被动论。这是清楚的，单纯的外部原因只能引起事物的机械的运动，即范围的大小，数量的增减，不能说明事物何以有性质上的千差万别及其互相变化。

The tactics we have derived from the struggle of the past three years are indeed different from any other tactics, ancient or modern, Chinese or foreign. With our tactics, the masses can be aroused for struggle on an ever-broadening scale, and no enemy, however powerful, can cope with us. Ours are guerrilla tactics. They consist mainly of the following points:
“Divide our forces to arouse the masses, concentrate our forces to deal with the enemy.”
“The enemy advances, we retreat; the enemy camps, we harass; the enemy tires, we attack; the enemy retreats, we pursue.”
“To extend stable base areas, employ the policy of advancing in waves; when pursued by a powerful enemy, employ the policy of circling around.”
“Arouse the largest numbers of the masses in the shortest possible time and by the best possible methods.”
These tactics are just like casting a net; at any moment we should be able to cast it or draw it in. We cast it wide to win over the masses and draw it in to deal with the enemy. Such are the tactics we have used for the past three years.
