它有许多东西我们可以学。当然，是要学习先进经验，不是学习落后经验。我们历来提的口号是学习苏联先进经验，谁要你去学习落后经验呀?有一些人，不管三七二十一，连苏联人放的屁都是香的，那也是主观主义。苏联人自己都说是臭的嘛!所以，要加以分析。我们说过，对斯大林要三七开。他们的主要的、大量的东西，是好的，有用的；部分的东西是错误的。我们也有部分的东西是不好的，我们自己就要丢掉，更不要别国来学这些坏事。但是，坏事也算一种经验，也有很大的作用。我们就有陈独秀、李立三、王明、张国焘、高岗、饶漱石这些人，他们是我们的教员。此外，我们还有别的教员。在国内来说，最好的教员是蒋介石。我们说不服的人，蒋介石一教，就说得服了。蒋介石用什么办法来教呢?他是用机关枪、大炮、飞机来教。还有帝国主义这个教员，它教育了我们六亿人民。一百多年来，几个帝国主义强国压迫我们，教育了我们。所以，坏事有个教育作用，有个借鉴作用。

It is highly important to grasp this fact. It enables us to understand that revolutions and revolutionary wars are inevitable in class society and that without them, it is impossible to accomplish any leap in social development and to overthrow the reactionary ruling classes and therefore impossible for the people to win political power. Communists must expose the deceitful propaganda of the reactionaries, such as the assertion that social revolution is unnecessary and impossible. They must firmly uphold the Marxist-Leninist theory of social revolution and enable the people to understand that social revolution is not only entirely necessary but also entirely practicable, and that the whole history of mankind and the triumph of the Soviet Union have confirmed this scientific truth.

Without preparedness superiority is not real superiority and there can be no initiative either. Having grasped this point, a force which is inferior but prepared can often defeat a superior enemy by surprise attack. We say an enemy on the move is easy to attack precisely because he is then off guard, that is, unprepared.
