Stalin made mistakes. He made mistakes towards us, for example, in 1927. He made mistakes towards the Yugoslavs too. One cannot advance without mista… - Mao Zedong

However, we must make a concrete study of the circumstances of each specific struggle of opposites and should not arbitrarily apply the formula discussed above to everything. Contradiction and struggle are universal and absolute, but the methods of resolving contradictions, that is, the forms of struggle, differ according to the differences in the nature of the contradictions. Some contradictions are characterized by open antagonism, others are not. In accordance with the concrete development of things, some contradictions which were originally non-antagonistic develop into antagonistic ones, while others which were originally antagonistic develop into non-antagonistic ones.

认识这种情形，极为重要。它使我们懂得，在阶级社会中，革命和革命战争是不可避免的，舍此不能完成社会发展的飞跃，不能推翻反动的统治阶级，而使人民获得政权。共产党人必须揭露反动派所谓社会革命是不必要的和不可能的等等欺骗的宣传，坚持马克思列宁主义的社会革命论，使人民懂得，这不但是完全必要的，而且是完全可能的，整个人类的历史和苏联的胜利，都证明了这个科学的真理。

这种人闹什么东西呢？闹名誉，闹地位，闹出风头。在他们掌管一部分事业的时候，就要闹独立性。为了这些，就要拉拢一些人，排挤一些人，在同志中吹吹拍拍，拉拉扯扯，把资产阶级政党的庸俗作风也搬进共产党里来了。这种人的吃亏在于不老实。我想，我们应该是老老实实地办事；在世界上要办成几件事，没有老实态度是根本不行的。什么人是老实人？马克思、恩格斯、列宁、斯大林是老实人，科学家是老实人。什么人是不老实的人？托洛茨基、布哈林、陈独秀、张国焘是大不老实的人，为个人利益为局部利益闹独立性的人也是不老实的人。一切狡猾的人，不照科学态度办事的人，自以为得计，自以为很聪明，其实都是最蠢的，都是没有好结果的。我们党校的学生一定要注意这个问题。我们一定要建设一个集中的统一的党，一切无原则的派别斗争，都要清除干净。要使我们全党的步调整齐一致，为一个共同目标而奋斗，我们一定要反对个人主义和宗派主义。
