我欢迎尼克松上台。为什么呢?他的欺骗性也有，但比较地少一点，你信不信?他跟你来硬的多，来软的也有。他如果想到北京来，你就捎个信，叫他偷偷地，不要公开，坐上一架飞机就可以来嘛。谈不成也可以，谈得成也可以嘛。何必那么僵着?但是你们美国是没有秘密的，一个总统出国是不可能秘密的。他要到中国来，一定会大吹大… - Mao Zedong

Our congress is being held in the following circumstances. A new situation has emerged after nearly eight years of resolute, heroic and indomitable struggle waged by the Chinese people with countless sacrifices and amid untold hardships against the Japanese aggressors; in the world as a whole, decisive victory has been gained in the just and sacred war against the fascist aggressors and the moment is near when the Japanese aggressors will be defeated by the Chinese people in co-ordination with the allied countries. But China remains disunited and is still confronted with a grave crisis. In these circumstances, what ought we to do? Beyond all doubt, the urgent need is to unite representatives of all political parties and groups and of people without any party affiliation and establish a provisional democratic coalition government for the purpose of instituting democratic reforms, surmounting the present crisis, mobilizing and unifying all the anti-Japanese forces in the country to fight in effective co-ordination with the allied countries for the defeat of the Japanese aggressors, and thus enabling the Chinese people to liberate themselves from the latter's clutches. After that it will be necessary to convene a national assembly on a broad democratic basis and set up a formally constituted democratic government, which will also be in the nature of a coalition and will have a still wider representation of people from all parties and groups or without any party affiliation, and which will lead the liberated people of the whole country in building an independent, free, democratic, united, prosperous and powerful new China. In short, we must take the line of unity and democracy, defeat the aggressors and build a new China.

马克思列宁主义认为：认识过程中两个阶段的特性，在低级阶段，认识表现为感性的，在高级阶段，认识表现为论理的，但任何阶段，都是统一的认识过程中的阶段。感性和理性二者的性质不同，但又不是互相分离的，它们在实践的基础上统一起来了。我们的实践证明：感觉到了的东西，我们不能立刻理解它，只有理解了的东西才更深刻地感觉它。感觉只解决现象问题，理论才解决本质问题。这些问题的解决，一点也不能离开实践。无论何人要认识什么事物，除了同那个事物接触，即生活于（实践于）那个事物的环境中，是没有法子解决的。不能在封建社会就预先认识资本主义社会的规律，因为资本主义还未出现，还无这种实践。马克思主义只能是资本主义社会的产物。马克思不能在自由资本主义时代就预先具体地认识帝国主义时代的某些特异的规律，因为帝国主义这个资本主义最后阶段还未到来，还无这种实践，只有列宁和斯大林才能担当此项任务。马克思、恩格斯、列宁、斯大林之所以能够作出他们的理论，除了他们的天才条件之外，主要地是他们亲自参加了当时的阶级斗争和科学实验的实践，没有这后一个条件，任何天才也是不能成功的。

人的概念的每一差异，都应把它看作是客观矛盾的反映。客观矛盾反映入主观的思想，组成了概念的矛盾运动，推动了思想的发展，不断地解决了人们的思想问题。
