We, the communists, do not want official positions; we want revolution. We must have a thoroughly revolutionary spirit and must be with the masses ev… - Mao Zedong

但是我们必须具体地研究各种矛盾斗争的情况，不应当将上面所说的公式不适当地套在一切事物的身上。矛盾和斗争是普遍的、绝对的，但是解决矛盾的方法，即斗争的形式，则因矛盾的性质不同而不相同。有些矛盾具有公开的对抗性，有些矛盾则不是这样。根据事物的具体发展，有些矛盾是由原来还非对抗性的，而发展成为对抗性的；也有些矛盾则由原来是对抗性的，而发展成为非对抗性的。

"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.

马克思主义的哲学认为，对立统一规律是宇宙的根本规律。这个规律，不论在自然界、人类社会和人们的思想中，都是普遍存在的。矛盾着的对立面又统一，又斗争，由此推动事物的运动和变化。矛盾是普遍存在的，不过按事物的性质不同，矛盾的性质也就不同。对于任何一个具体的事物说来，对立的统一是有条件的、暂时的、过渡的，因而是相对的，对立的斗争则是绝对的。
