“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 closely and 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; 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.”
