We must have faith in the masses and we must have faith in the Party. These are two cardinal principles. If we doubt these principles, we shall accom… - Mao Zedong

I said, now that I’m collaborating with the rightists, my reputation isn’t good. I said, in your [the Americans'] country there are two parties and it’s been said that the Democrats are more enlightened. As for the Republicans, they lean more to the right. I said there is nothing great about the Democrats. I neither admire nor am interested in them. I said, when you [Nixon] were running for President, I gave you my vote. You are still not aware of that. [...] This time round, we also gave you our vote [<nowiki/>Tanaka]. It’s exactly like you said. If the main player, which is the Liberal Democratic Party [of Japan], doesn’t come here, how can we resolve the issue? [...] I said, that communist party of yours in Japan, I’m not interested in them.

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.

大银行、大工业、大商业，归这个共和国的国家所有。“凡本国人及外国人之企业，或有独占的性质，或规模过大为私人之力所不能办者，如银行、铁道、航路之属，由国家经营管理之，使私有资本制度不能操纵国民之生计，此则节制资本之要旨也。”这也是国共合作的国民党的第一次全国代表大会宣言中的庄严的声明，这就是新民主主义共和国的经济构成的正确的方针。在无产阶级领导下的新民主主义共和国的国营经济是社会主义的性质，是整个国民经济的领导力量，但这个共和国并不没收其他资本主义的私有财产，并不禁止“不能操纵国民生计”的资本主义生产的发展，这是因为中国经济还十分落后的缘故。
