A Communist should have largeness of mind and he should be staunch and active, looking upon the interests of the revolution as his very life and subordinating his personal interests to those of the revolution; always and everywhere he should adhere to principle and wage a tireless struggle against all incorrect ideas and actions, so as to consolidate the collective life of the Party and strengthen the ties between the Party and the masses; he should be more concerned about the Party and the masses than about any private person, and more concerned about others than about himself. Only thus can he be considered a Communist.
Nelson Rockefeller, heir to a global economic empire, had commissioned Rivera to paint the mural, insisting in the fine print that “no controversial figures” be included. Rivera defied the capitalist, including the faces of Marx, Lenin and Trotsky and refusing to paint over them.
Rockefeller had the mural covered, then destroyed in early 1934. Rivera recreated a smaller version, “Man, Controller of the Universe,” in Mexico City.
