//@lhsw:我想起了伯特兰罗素勋爵留给后人说过的忠告：在理智层面我的建议是：当你在做任何具体研究或哲学思考时，一定要问问自己：事实到底是什么，事实所支持的真相又是什么？。专注于事实，并且只能专注于事实，永远不要让被自己主观臆想的观念所左右，或者仅仅为了获得更好的社交目的而妥协自己的信念。关于理智层面，这就是我想提醒各位的。
The intellectual thing I should want to say to them is this: When you are studying any matter or considering any philosophy, ask yourself only what are the facts and what is the truth that the facts bear out. Never let yourself be diverted either by what you wish to believe or by what you think would have beneficent social effects if it were believed, but look only and solely at what are the facts. That is the intellectual thing that I should wish to say.

The moral thing I should wish to say to them is very simple. I should say: Love is wise, hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other. We have to learn to put up with the fact that some people say things that we don’t like. We can only live together in that way, and if we are to live together and not die together we must learn a kind of charity and a kind of tolerance which is absolutely vital to the continuation of human life on this planet.
