进步和进步的缓慢是目前时局的两个特点，后一个特点和战争的迫切要求很不相称，这就是使得爱国志士们大为发愁的地方。然而我们是在革命战争中，革命战争是一种抗毒素，它不但将排除敌人的毒焰，也将清洗自己的污浊。凡属正义的革命的战争，其力量是很大的，它能改造很多事物，或为改造事物开辟道路。中日战争将改造中日两… - Mao Zedong

The culture of New Democracy should likewise be "shared by all the common people", that is, it should be a national, scientific and mass culture, and must under no circumstances be a culture "privately owned by the few".
Such is the general or fundamental programme which we Communists advocate for the present stage, the entire stage of the bourgeois-democratic revolution. This is our minimum programme as against our future or maximum programme of socialism and communism. Its realization will carry the Chinese state and Chinese society a step forward, from a colonial, semi-colonial and semi-feudal to a new-democratic state and society.
The political leadership of the proletariat and the proletarian-led state and co-operative sectors of the economy required by our programme are socialist factors. Yet the fulfilment of this programme will not turn China into a socialist society.
We Communists do not conceal our political views. Definitely and beyond all doubt, our future or maximum programme is to carry China forward to socialism and communism. Both the name of our Party and our Marxist world outlook unequivocally point to this supreme ideal of the future, a future of incomparable brightness and splendour. On joining the Party, every Communist has two clearly-defined objectives at heart, the new-democratic revolution now and socialism and communism in the future, and for these he will fight despite the animosity of the enemies of communism and their vulgar and ignorant calumny, abuse and ridicule, which we must firmly combat. As for the well-meaning sceptics, we should explain things to them with goodwill and patience and not attack them. All this is very clear, definite and unequivocal.

The Marxist philosophy of dialectical materialism has two outstanding characteristics. One is its class nature: it openly avows that dialectical materialism is in the service of the proletariat. The other is its practicality: it emphasizes the dependence of theory on practice, emphasizes that theory is based on practice and in turn serves practice. The truth of any knowledge or theory is determined not by subjective feelings, but by objective results in social practice. Only social practice can be the criterion of truth. The standpoint of practice is the primary and basic standpoint in the dialectical materialist theory of knowledge.

一个人从那样的小学一直读到那样的大学，毕业了，算有知识了。但是他有的只是书本上的知识，还没有参加任何实际活动，还没有把自己学得的知识应用到生活的任何部门里去。像这样的人是否可以算得一个完全的知识分子呢？我以为很难，因为他的知识还不完全。什么是比较完全的知识呢？一切比较完全的知识都是由两个阶段构成的：第一阶段是感性知识，第二阶段是理性知识，理性知识是感性知识的高级发展阶段。学生们的书本知识是什么知识呢？假定他们的知识都是真理，也是他们的前人总结生产斗争和阶级斗争的经验写成的理论，不是他们自己亲身得来的知识。他们接受这种知识是完全必要的，但是必须知道，就一定的情况说来，这种知识对于他们还是片面性的，这种知识是人家证明了，而在他们则还没有证明的。最重要的，是善于将这些知识应用到生活和实际中去。所以我劝那些只有书本知识但还没有接触实际的人，或者实际经验尚少的人，应该明白自己的缺点，将自己的态度放谦虚一些。
