这种人闹什么东西呢？闹名誉，闹地位，闹出风头。在他们掌管一部分事业的时候，就要闹独立性。为了这些，就要拉拢一些人，排挤一些人，在同志中吹吹拍拍，拉拉扯扯，把资产阶级政党的庸俗作风也搬进共产党里来了。这种人的吃亏在于不老实。我想，我们应该是老老实实地办事；在世界上要办成几件事，没有老实态度是根本不行… - Mao Zedong

什么是知识？自从有阶级的社会存在以来，世界上的知识只有两门，一门叫做生产斗争知识，一门叫做阶级斗争知识。自然科学、社会科学，就是这两门知识的结晶，哲学则是关于自然知识和社会知识的概括和总结。

当着某一件事情（任何事情都是一样）要做，但是还没有方针、方法、计划或政策的时候，确定方针、方法、计划或政策，也就是主要的决定的东西。当着政治文化等等上层建筑阻碍着经济基础的发展的时候，对于政治上和文化上的革新就成为主要的决定的东西了。我们这样说，是否违反了唯物论呢？没有。因为我们承认总的历史发展中是物质的东西决定精神的东西，是社会的存在决定社会的意识；但是同时又承认而且必须承认精神的东西的反作用，社会意识对于社会存在的反作用，上层建筑对于经济基础的反作用。这不是违反唯物论，正是避免了机械唯物论，坚持了辩证唯物论。

Without democracy there cannot be any correct centralism because people’s ideas differ, and if their understanding of things lacks unity then centralism cannot be established. What is centralism? First of all it is a centralization of correct ideas, on the basis of which unity of understanding, policy, planning, command and action are achieved. This is called centralized unification. If people still do not understand problems, if they have ideas but have not expressed them, or are angry but still have not vented their anger, how can centralized unification be established? If there is no democracy we cannot possibly summarize experience correctly. If there is no democracy, if ideas are not coming from the masses, it is impossible to establish a good line, good general and specific policies and methods. Our leading organs merely play the role of a processing plant in the establishment of a good line and good general and specific policies and methods. Everyone knows that if a factory has no raw material it cannot do any processing. If the raw material is not adequate in quantity and quality it cannot produce good finished products. Without democracy, you have no understanding of what is happening down below; the situation will be unclear; you will be unable to collect sufficient opinions from all sides; there can be no communication between top and bottom; top-level organs of leadership will depend on one-sided and incorrect material to decide issues, thus you will find it difficult to avoid being subjectivist; it will be impossible to achieve unity of understanding and unity of action, and impossible to achieve true centralism. Is not the main item for discussion at this session of our conference opposition to dispersionism and the strengthening of centralized unification? If we fail to promote democracy in full measure, then will this centralism and this unification be true or false? Will it be real or empty? Will it be correct or incorrect? Of course it must be false, empty and incorrect.
