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… - Mao Zedong

Armed with Marxist-Leninist theory and ideology, the Communist Party of China has brought a new style of work to the Chinese people, a style of work that essentially entails integrating theory with practice, forging close links with the masses and practicing self-criticism.

As opposed to the metaphysical world outlook, the world outlook of materialist dialectics holds that in order to understand the development of a thing we should study it internally and in its relations with other things; in other words, the development of things should be seen as their internal and necessary self-movement, while each thing in its movement is interrelated with and interacts on the things around it. The fundamental cause of the development of a thing is not external but internal; it lies in the contradictoriness within the thing. There is internal contradiction 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. Thus materialist dialectics effectively combats the theory of external causes, or of an external motive force, advanced by metaphysical mechanical materialism and vulgar evolutionism. It is evident that purely external causes can only give rise to mechanical motion, that is, to changes in scale or quantity, but cannot explain why things differ qualitatively in thousands of ways and why one thing changes into another.

The culture of New Democracy should likewise be "shared by all the common people", that is, it should be a national, scientific and mass culture, and must under no circumstances be a culture "privately owned by the few".
Such is the general or fundamental programme which we Communists advocate for the present stage, the entire stage of the bourgeois-democratic revolution. This is our minimum programme as against our future or maximum programme of socialism and communism. Its realization will carry the Chinese state and Chinese society a step forward, from a colonial, semi-colonial and semi-feudal to a new-democratic state and society.
The political leadership of the proletariat and the proletarian-led state and co-operative sectors of the economy required by our programme are socialist factors. Yet the fulfilment of this programme will not turn China into a socialist society.
We Communists do not conceal our political views. Definitely and beyond all doubt, our future or maximum programme is to carry China forward to socialism and communism. Both the name of our Party and our Marxist world outlook unequivocally point to this supreme ideal of the future, a future of incomparable brightness and splendour. On joining the Party, every Communist has two clearly-defined objectives at heart, the new-democratic revolution now and socialism and communism in the future, and for these he will fight despite the animosity of the enemies of communism and their vulgar and ignorant calumny, abuse and ridicule, which we must firmly combat. As for the well-meaning sceptics, we should explain things to them with goodwill and patience and not attack them. All this is very clear, definite and unequivocal.
