如果有了正确的理论，只是把它空谈一阵，束之高阁，并不实行，那末，这种理论再好也是没有意义的。认识从实践始，经过实践得到了理论的认识，还须再回到实践去。认识的能动作用，不但表现于从感性的认识到理性的认识之能动的飞跃，更重要的还须表现于从理性的认识到革命的实践这一个飞跃。抓着了世界的规律性的认识，必须… - Mao Zedong

我们的同志必须明白，我们学马克思列宁主义不是为着好看，也不是因为它有什么神秘，只是因为它是领导无产阶级革命事业走向胜利的科学。直到现在，还有不少的人，把马克思列宁主义书本上的某些个别字句看作现成的灵丹圣药，似乎只要得了它，就可以不费气力地包医百病。这是一种幼稚者的蒙昧，我们对这些人应该作启蒙运动。那些将马克思列宁主义当宗教教条看待的人，就是这种蒙昧无知的人。对于这种人，应该老实地对他说，你的教条一点什么用处也没有。马克思、恩格斯、列宁、斯大林曾经反复地讲，我们的学说不是教条而是行动的指南。这些人偏偏忘记这句最重要最重要的话。

In approaching a problem a Marxist should see the whole as well as the parts. A frog in a well says, "The sky is no bigger than the mouth of the well." That is untrue, for the sky is not just the size of the mouth of the well. If it said, "A part of the sky is the size of the mouth of a well", that would be true, for it tallies with the facts. What we say is that in one respect the Red Army has failed (i.e., failed to maintain its original positions), but in another respect it has won a victory (i.e., in executing the plan of the Long March). In one respect the enemy won a victory (i.e., in occupying our original positions), but in another respect he has failed (i.e., failed to execute his plan of “encirclement ant suppression” and of “pursuit and suppression”). That is the only appropriate formulation, for we have completed the Long March.

不但要关心党的干部，还要关心非党的干部。党外存在着很多的人材，共产党不能把他们置之度外。去掉孤傲习气，善于和非党干部共事，真心诚意地帮助他们，用热烈的同志的态度对待他们，把他们的积极性组织到抗日和建国的伟大事业中去，这是每一个共产党员的责任。
