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.

Original: (zh-CN) 不但要关心党的干部,还要关心非党的干部。党外存在着很多的人材,共产党不能把他们置之度外。去掉孤傲习气,善于和非党干部共事,真心诚意地帮助他们,用热烈的同志的态度对待他们,把他们的积极性组织到抗日和建国的伟大事业中去,这是每一个共产党员的责任。

If we were not complacent we could not bear to live in a world in which these events were happening, these people were dying in the midst of plenty. We would not allow it to happen if we were not complacent. This is something which we need to remember... because this is the root of all the troubles in the world. It is a sign of our separateness. Complacency results from separation — the sense that we are separate and that by competition we become superior — and that superiority allows us to live what we call ‘well’. But we cannot live ‘well’ when two-thirds of the world are living and dying in absolute poverty. It is not possible to do so with impunity, and we do not. The result is crime. The result is catastrophe of one kind or another — governments which create wars for oil, for example. That is a catastrophe, and it is only possible because we are complacent, because we do not acknowledge the needs of millions of people who cannot take for granted what we take for granted: regular food, leisure, education and healthcare.
