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.

不能把过程中所有的矛盾平均看待，必须把它们区别为主要的和次要的两类，着重于捉住主要的矛盾，已如上述。但是在各种矛盾之中，不论是主要的或次要的，矛盾着的两个方面，又是否可以平均看待呢？也是不可以的。无论什么矛盾，矛盾的诸方面，其发展是不平衡的。有时候似乎势均力敌，然而这只是暂时的和相对的情形，基本的形态则是不平衡。矛盾着的两方面中，必有一方面是主要的，他方面是次要的。其主要的方面，即所谓矛盾起主导作用的方面。事物的性质，主要地是由取得支配地位的矛盾的主要方面所规定的。

下定决心，不怕牺牲，排除万难，去争取胜利。
