What kind of spirit is this that makes a foreigner selflessly adopt the cause of the Chinese people's liberation as his own? It is the spirit of internationalism, the spirit of communism, from which every Chinese Communist must learn…. We must unite with the proletariat of all the capitalist countries, with the proletariat of Japan, Britain, the United States, Germany, Italy and all other capitalist countries, before it is possible to overthrow imperialism, to liberate our nation and people, and to liberate the other nations and peoples of the world. This is our internationalism, the internationalism with which we oppose both narrow nationalism and narrow patriotism.
A communist must be selfless, with the interests of the masses at heart. He must also possess a largeness of mind, as well as a practical, far-sighted mindset.
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 impetu for the suppression of the old society by the new.
Every Communist working in the mass movements should be a friend of the masses and not a boss over them, an indefatigable teacher and not a bureaucratic politician.
