As regards the sequence in the movement of man's knowledge, there is always a gradual growth from the knowledge of individual and particular things t… - Mao Zedong

According to materialist dialectics, changes in nature are due chiefly to the development of the internal contradictions in nature. Changes in society are due chiefly to the development of the internal contradictions in society, that is, the contradiction between the productive forces and the relations of production, the contradiction between classes and the contradiction between the old and the new; it is the development of these contradictions that pushes society forward and gives the impetus for the supersession of the old society by the new. Does materialist dialectics exclude external causes? Not at all. It holds that external causes are the condition of change and internal causes are the basis of change, and that external causes become operative through internal causes. In a suitable temperature an egg changes into a chicken, but no temperature can change a stone into a chicken, because each has a different basis. There is constant interaction between the peoples of different countries. In the era of capitalism, and especially in the era of imperialism and proletarian revolution, the interaction and mutual impact of different countries in the political, economic and cultural spheres are extremely great. The October Socialist Revolution ushered in a new epoch in world history as well as in Russian history. It exerted influence on internal changes in the other countries in the world and, similarly and in a particularly profound way, on internal changes in China. These changes, however, were effected through the inner laws of development of these countries, China included. In battle, one army is victorious and the other is defeated, both the victory and the defeat are determined by internal causes.

在上海时，一个中央分裂为两个中央，在长征中与张国焘分裂，高饶事件是部分分裂。部分的分裂是经常的。去年以来。全国有一半的省份在领导集团内发生了分裂。人身上海天都要脱发、脱皮，这就是灭亡一部分细胞。从小孩起就要灭亡一部分细胞，这才有利于生长。如果没有灭亡，人就不能生存。自从孔夫子以来，人要不灭亡那不得了。灭亡有好处，可以做肥料，你说不做，实际做了。精神上要有准备。部分的分裂每天都存在。分裂灭亡总会有的。没有分裂．不利于发展。整个的灭亡，也是历史的必然。整个讲，作为阶级斗争工具的党和国家，是要灭亡的。但在它的历史任务未完成前，是要巩固它，不希望分裂，但要准备分裂。没有准备，就要分裂。有准备。就可避免大分裂。大型、中型的分裂是暂时的。匈牙利事件是大型的，高饶事件、莫洛托失事件是中型的。每个支部都在起变化，有些开除，有些进来，有些工作很好，有些犯错误。永远不起变化是不可能的。列宁经常说：国家总有两种可能。或者胜利，或者灭亡。我们中华人为共和国也有两种可能，胜利下去，或者灭亡。列宁是不隐讳灭亡这种可能性的，我们人民共和国也有两种可能性，不要否定这种可能性。我们手里没有原子弹，打起来，三十六计，走为上计，他占北京、上海、武汉，我们打游击，倒退十几年，二十年，回到延安时代。所以一方面我们要积极准备，大搞钢铁，搞机器，搞铁路，争取三四年内搞几千万吨钢，建立起工业基础，使我们比现在更巩固。

We should allow democratic personages to challenge us with opposing views and give them a free hand to criticize us. Otherwise we would be a little like the Kuomintang. The Kuomintang was mortally afraid of criticism and went in fear and trepidation each time the Political Council was in session. Criticisms from democratic personages can be of only two kinds, those that are wrong and those that are not. Criticisms that are not wrong can help remedy our shortcomings while wrong ones must be refuted. As for such types as Liang Shu-ming, Peng Yi-hu and Chang Nai-chi, if they want to fart, let them. That will be to our advantage, for everybody can judge whether the smell is good or foul, and through discussion the majority can be won over and these types isolated. If they want to create trouble, let them have their fill of it.
