马克思主义的哲学辩证唯物论有两个最显著的特点：一个是它的阶级性，公然申明辩证唯物论是为无产阶级服务的；再一个是它的实践性，强调理论对于实践的依赖关系，理论的基础是实践，又转过来为实践服务。判定认识或理论之是否真理，不是依主观上觉得如何而定，而是依客观上社会实践的结果如何而定。真理的标准只能是社会的… - Mao Zedong

China's protracted war has exacted and will continue to exact great sacrifices from the Chinese people, but at the same time this very war has tempered them. It has awakened and united the Chinese people to a greater degree than all their great struggles in the last hundred years. The Chinese people face not only a formidable national enemy but also powerful domestic reactionary forces which are in fact helping the enemy; this is one side of the picture. But the other side is that the Chinese people are not only more politically conscious than ever before but have built powerful Liberated Areas and a nation-wide democratic movement that is growing day by day. These constitute favourable domestic conditions. If the defeats and setbacks in the Chinese people's struggles of the last hundred years were due to the absence of certain necessary international and domestic conditions, then today the situation is different--all the necessary conditions are present. There is every possibility of avoiding defeat and winning victory. We shall be victorious if we can unite the whole people in resolute struggle and give them proper leadership.

对民主人士，我们要让他们唱对台戏，放手让他们批评。如果我们不这样做，就有点象国民党了。国民党很怕批评，每次开参政会就诚惶诚恐。民主人士的批评也无非是两种：一种是错的，一种是不错的。不错的可以补足我们的短处；错的要反驳。至于梁漱溟、彭一湖、章乃器那一类人，他们有屁就让他们放，放出来有利，让大家闻一闻，是香的还是臭的，经过讨论，争取多数，使他们孤立起来。他们要闹，就让他们闹够。

In seeking victory, those who direct a war cannot overstep the limitations imposed by the objective conditions. Within these limitations, however, they can and must play a dynamic role in striving for victory. The stage of action for commanders in a war must be built upon objective possibilities, but on that stage they can direct the performance of many a drama, full of sound and color, power and grandeur.
