Those experienced in work must take up the study of theory and must read seriously; only then will they be able to systematize and synthesize their experience and raise it to the level of theory, only then will they not mistake their partial experience for universal truth and not commit empiricist errors.
Mao ZedongTaken as a whole, the Chinese revolutionary movement led by the Communist Party embraces the two stages, i.e., the democratic and the socialist revolutions, which are two essentially different revolutionary processes, and the second process can be carried through only after the first has been completed. The democratic revolution is the necessary preparation for the socialist revolution, and the socialist revolution is the inevitable sequel to the democratic revolution. The ultimate aim for which all communists strive is to bring about a socialist and communist society.
Mao ZedongAt certain times in the revolutionary struggle, the difficulties outweigh the favorable conditions and so constitute the principal aspect of the contradiction and the favorable conditions constitute the secondary aspect. But through their efforts the revolutionaries can overcome the difficulties step by step and open up a favorable new situation, thus a difficult situation yields place to a favorable one.
Mao ZedongSome people have read a few Marxist books and think themselves quite learned but what they have read has not penetrated, has not struck root in their minds, so that they do not know how to use it and their class feelings remain as of old. Others are very conceited and having learned some book-phrases, think them terrific and are very cocky; but whenever a storm blows up, they take a stand very different from that of the workers and the majority of the peasants. They waver while the latter stand firm, they equivocate while the latter are forthright.
