革命不是請客吃飯，不是做文章，不是繪畫繡花，不能那樣雅致，那樣從容不迫，文質彬彬，那樣溫良恭儉讓。革命是暴動，是一個階級推翻一個階級的暴烈的行動。 - Mao Zedong

Opposition and struggle between ideas of different kinds constantly occur within the Party; this is a reflection within the Party of contradictions between classes and between the new and the old in society. If there were no contradictions in the Party and no ideological struggles to resolve them, the Party's life would come to an end.

Our educational policy must enable everyone who receives an education to develop morally, intellectually and physically and become a worker with both socialist consciousness and culture. We must spread the idea of building our country through diligence and thrift. We must help all our young people to understand that ours is still a very poor country, that we cannot change this situation radically in a short time, and that only through decades of united effort by our younger generation and all our people, working with their own hands, can China be made prosperous and strong.

Our agrarian revolution has been a process in which the landlord class owning the land is transformed into a class that has lost its land, while the peasants who once lost their land are transformed into small holders who have acquired land, and it will be such a process once again. In given conditions having and not having, acquiring and losing, are interconnected; there is identity of the two sides. Under socialism, private peasant ownership is transformed into the public ownership of socialist agriculture; this has already taken place in the Soviet Union, as it will take place everywhere else. There is a bridge leading from private property to public property, which in philosophy is called identity, or transformation into each other, or interpenetration.
