一切矛盾着的东西，互相联系着，不但在一定条件之下共处于一个统一体中，而且在一定条件之下互相转化，这就是矛盾的同一性的全部意义。列宁所谓“怎样成为同一的（怎样变成同一的），——在怎样的条件之下它们互相转化，成为同一的”，就是这个意思。 - Mao Zedong

中国人把结婚叫红喜事，死人叫做白喜事，合起来叫红白喜事，我看很有道理。中国人是懂得辩证法的。结婚可以生小孩，母亲分裂出孩子来．是个突变，是喜事。一个母亲分数出三个、两个，一个小人出来。多子女的分裂出六个、七个，七个、八个，甚至十个，像航空母舰一样。我不是不赞成节育，我是讲辩证法，是说新事物的发生，人的生产，这是喜事，是变化，一个变两个，两个变四个。至于死亡，老百姓也叫喜事。一方面并追悼会，哭鼻子，要送葬，人之常情。另一方面是喜事。也确实是喜事。你们设想，如果孔夫子还在，也在怀仁堂开会，他二千多岁了，就很不妙。讲辩证法而又不赞成灭亡，是形而上学。有灾难，是社会现象。灾变，是宇宙根本的规律。生是突变，死也是突变。由生到死几十年的渐变。假如蒋介石死了。我们都会鼓掌。杜勒斯死了，我们没有掉眼泪。这是因为旧社会事物的灭亡是好事，大家都希望。新事物的产生是好事，新事物的灭亡当然不好。如一九零五举俄国革命的失败。南方我们根据地的丢失，等于现在的苗子被雹子和暴雨打掉，这当然不好，这就发生补苗问题。

Modern warfare is not a matter in which armies alone can determine victory or defeat. Especially in guerrilla combat, we must rely on the force of the popular masses, for it is only thus that we can have a guarantee of success. The support of the masses offers us great advantages as regards transport, assistance to wounded, intelligence, disruption of the enemy’s position, etc. At the same time, the enemy can be put into an isolated position, thus further increasing our advantages. If, by misfortune, we are defeated, it will also be possible to escape or to find concealment. Consequently, we must not lightly give battle in places where the masses are not organized and linked to us.

When talking of responsibility, XX and XX both have some responsibility, as does XX of the Ministry of Agriculture. But one with the most responsibility is me. Old Ke, does any responsibility rest on you for your invention? [Old Ke said: “yes.”] Was it lighter than mine? Yours is a question of ideology, mine of 10,700,000 tons and ninety million people going into battle. The chaos caused was on a grand scale and I take responsibility. Comrades, you must all analyze your own responsibility. If you have to shit, shit! If you have to fart, fart! You will feel much better for it.
