(一)不是人们的意识决定人们的存在,相反,是人们的社会存在决定人们的意识。——马克思原则不是研究的出发点,而是它的最终结果;这些原则不是被应用于自然界和人类历史,而是从它们中抽象出来的;不是自然界和人类去适应原则,而是原则只有在适合于自然界和历史的情况下才是正确的。——恩格斯从物到感觉和思想呢,还是从思想和感觉到物?恩格斯主张第一条路线,即唯物主义的路线。马赫主张第二条路线,即唯心主义的路线。——列宁人的正确思想是从那里来的?是从天上掉下来的吗?不是。是自己头脑里固有的吗?不是。人的正确思想,只能从社会实践中来,只能从社会的生产斗争、阶级斗争和科学实验这三项实践中来。——毛主席 (1) It is not people's consciousness that determines the existence of people. On the contrary, people's social existence determines people's awareness. Marx's principle is not the starting point of the study but its end result; these principles are not applied to nature and human history but abstract from them; not the nature and the human being to adapt to the principle, In the case of nature and history is correct. - From Engels to feeling and thought, or from thoughts and feelings? Engels advocates the first line, that is, the materialist line. Maher advocates the second line, the idealist line. - Where did the correct thinking of the Lenin come from? Did it fall from heaven? Is it inherent in my mind? The correct thinking of man can only come from social practice and can only come from the three practices of social production struggle, class struggle and scientific experiment. - Chairman Mao
