There may be thousands of principles of Marxism, but in the final analysis they can be summed up in one sentence: Rebellion is justified.
Mao ZedongThe theory of Marx, Engels, Lenin and Stalin is universally applicable. We should regard it not as a dogma, but as a guide to action. Studying it is not merely a matter of learning terms and phrases but of learning Marxism-Leninism as the science of revolution. It is not just a matter of understanding the general laws derived by Marx, Engels, Lenin and Stalin from their extensive study of real life and revolutionary experience, but of studying their standpoint and method in examining and solving problems.
Mao ZedongIt is up to us to organize the people. As for the reactionaries in China, it is up to us to organize the people to overthrow them. Everything reactionary is the same; if you do not hit it, it will not fall. This is also like sweeping the floor; as a rule, where the broom does not reach, the dust will not vanish of itself.
Mao ZedongWe should never pretend to know what we don't know, we should not feel ashamed to ask and learn from people below, and we should listen carefully to the views of the cadres at the lowest levels. Be a pupil before you become a teacher; learn from the cadres at the lower levels before you issue orders.
