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.
Today in history: February 21, 1848 - On the eve of the French and German revolutions of 1848, Karl Marx and Friedrich Engels published the Manifesto of the Communist Party, commonly referred to as the Communist Manifesto, in London.

“The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win.”
