指导战争的人们不能超越客观条件许可的限度期求战争的胜利，然而可以而且必须在客观条件的限度之内，能动地争取战争的胜利。战争指挥员活动的舞台，必须建筑在客观条件的许可之上，然而他们凭借这个舞台，却可以导演出很多有声有色、威武雄壮的戏剧来。 - Mao Zedong

What should our policy be towards non-Marxist ideas? As far as unmistakable counter-revolutionaries and saboteurs of the socialist cause are concerned, the matter is easy, we simply deprive them of their freedom of speech. But incorrect ideas among the people are quite a different matter. Will it do to ban such ideas and deny them any opportunity for expression? Certainly not. It is not only futile but very harmful to use crude methods in dealing with ideological questions among the people, with questions about man's mental world. You may ban the expression of wrong ideas, but the ideas will still be there. On the other hand, if correct ideas are pampered in hothouses and never exposed to the elements and immunized against disease, they will not win out against erroneous ones. Therefore, it is only by employing the method of discussion, criticism and reasoning that we can really foster correct ideas and overcome wrong ones, and that we can really settle issues.

Now there are two different attitudes towards learning from others. One is the dogmatic attitude of transplanting everything, whether or not it is suited to our conditions. This is no good. The other attitude is to use our heads and learn those things that suit our conditions, that is, to absorb whatever experience is useful to us. That is the attitude we should adopt.

It is difficult to avoid mistakes, the point is to correct them honestly. Too many people have been arrested in Szechwan and many mass organizations are branded as reactionary. All these are wrong, but they have been quickly rectified.
