我们需要的是热烈而镇定的情绪，紧张而有秩序的工作。 - Mao Zedong

Racial discrimination in the United States is a product of the colonialist and imperialist system. The contradiction between the Black masses in the United States and the U.S. ruling circles is a class contradiction. Only by overthrowing the reactionary rule of the U.S. monopoly capitalist class and destroying the colonialist and imperialist system can the Black people in the United States win complete emancipation. The Black masses and the masses of white working people in the United States have common interests and common objectives to struggle for. Therefore, the Afro-American struggle is winning sympathy and support from increasing numbers of white working people and progressives in the United States. The struggle of the Black people in the United States is bound to merge with the American workers' movement, and this will eventually end the criminal rule of the U.S. monopoly capitalist class.

主观主义、宗派主义、党八股，现在已不是占统治地位的作风了，这不过是一股逆风，一股歪风，是从防空洞里跑出来的。

According to materialist dialectics, changes in nature are due chiefly to the development of the internal contradictions in nature. Changes in society are due chiefly to the development of the internal contradictions in society, that is, the contradiction between the productive forces and the relations of production, the contradiction between classes and the contradiction between the old and the new; it is the development of these contradictions that pushes society forward and gives the impetus for the supersession of the old society by the new. Does materialist dialectics exclude external causes? Not at all. It holds that external causes are the condition of change and internal causes are the basis of change, and that external causes become operative through internal causes. In a suitable temperature an egg changes into a chicken, but no temperature can change a stone into a chicken, because each has a different basis. There is constant interaction between the peoples of different countries. In the era of capitalism, and especially in the era of imperialism and proletarian revolution, the interaction and mutual impact of different countries in the political, economic and cultural spheres are extremely great. The October Socialist Revolution ushered in a new epoch in world history as well as in Russian history. It exerted influence on internal changes in the other countries in the world and, similarly and in a particularly profound way, on internal changes in China. These changes, however, were effected through the inner laws of development of these countries, China included. In battle, one army is victorious and the other is defeated, both the victory and the defeat are determined by internal causes.
