美国垄断资本集团如果坚持推行它的侵略政策和战争政策，势必有一天要被全世界人民处以刑。其他美国帮凶也将是这样。 - Mao Zedong

我欢迎尼克松上台。为什么呢?他的欺骗性也有，但比较地少一点，你信不信?他跟你来硬的多，来软的也有。他如果想到北京来，你就捎个信，叫他偷偷地，不要公开，坐上一架飞机就可以来嘛。谈不成也可以，谈得成也可以嘛。何必那么僵着?但是你们美国是没有秘密的，一个总统出国是不可能秘密的。他要到中国来，一定会大吹大擂，就会说其目的就是要拉中国整苏联，所以他现在还不敢这样做。整苏联，现在对美国不利；整中国，对于美国也不利。

There is an ancient Chinese fable called "The Foolish Old Man Who Removed the Mountains". It tells of an old man who lived in northern China long, long ago and was known as the Foolish Old Man of North Mountain. His house faced south and beyond his doorway stood the two great peaks, Taihang and Wangwu, obstructing the way. He called his sons, and hoe in hand they began to dig up these mountains with great determination. Another graybeard, known as the Wise Old Man, saw them and said derisively, "How silly of you to do this! It is quite impossible for you few to dig up those two huge mountains." The Foolish Old Man replied, "When I die, my sons will carry on; when they die, there will be my grandsons, and then their sons and grandsons, and so on to infinity. High as they are, the mountains cannot grow any higher and with every bit we dig, they will be that much lower. Why can't we clear them away?" Having refuted the Wise Old Man's wrong view, he went on digging every day, unshaken in his conviction. God was moved by this, and he sent down two angels, who carried the mountains away on their backs. Today, two big mountains lie like a dead weight on the Chinese people. One is imperialism, the other is feudalism. The Chinese Communist Party has long made up its mind to dig them up. We must persevere and work unceasingly, and we, too, will touch God's heart. Our God is none other than the masses of the Chinese people. If they stand up and dig together with us, why can't these two mountains be cleared away?

人们要想得到工作的胜利即得到预想的结果，一定要使自己的思想合于客观外界的规律性，如果不合，就会在实践中失败。人们经过失败之后，也就从失败取得教训，改正自己的思想使之适合于外界的规律性，人们就能变失败为胜利，所谓“失败者成功之母”，“吃一堑长一智”，就是这个道理。
