"While we recognize that in the general development of history the material determines the mental and social being determines social consciousness, we also - and indeed must - recognize the reaction of mental on material things, of social consciousness on social being and of the superstructure on the economic base. This does not go against materialism; on the contrary, it avoids mechanical materialism and firmly upholds dialectical materialism."

“The fundamental cause of the development of a thing is not external but internal; it lies in the contradictoriness within the thing. This internal contradiction exists in every single thing, hence its motion and development. Contradictoriness within a thing is the fundamental cause of its development, while its interrelations and interactions with other things are secondary causes.”

“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.”

“In the twenty-four years since its birth in 1921, the Communist Party of China has gone through three great struggles--the Northern Expedition, the Agrarian Revolutionary War and the War of Resistance Against Japan which is still going on. From its very beginning our Party has based itself on the theory of Marxism-Leninism, for Marxism-Leninism is the crystallization of the most correct and most revolutionary scientific thought of the world proletariat. When the universal truth of Marxism-Leninism began to be integrated with the concrete practice of the Chinese revolution, the Chinese revolution took on an entirely new complexion and the entire historical stage of New Democracy emerged. Armed with Marxist-Leninist theory, the Communist Party of China has brought a new style of work to the Chinese people, a style of work which essentially entails integrating theory with practice, forging close links with the masses and practicing self-criticism.”

“Do not stop half way and do not ever go backward. There is no way behind you.”

“Enterprises, such as banks, railways and airlines, whether Chinese-owned or foreign-owned, which are either monopolistic in character or too big for private management, shall be operated and administered by the state, so that private capital cannot dominate the livelihood of the people: this is the main principle of the regulation of capital.”

“New things always have to experience difficulties and setbacks as they grow. It is sheer fantasy to imagine that the cause of socialism is all plain sailing and easy success, without difficulties and setbacks or the exertion of tremendous efforts.”
