Scientists are constantly doing research, and if you ask them what they are doing, they say, "Oh, it is for the next generation, for the future." But I say, "What about you? What about your skyscraper? If in your next life you are going to be a tree, what will you do with your next generation then?" But he is an ass. He does not know that he is going to stand before his skyscraper for ten thousand years. And what about the next generation? If there is no petrol, what will the next generation do? And how will the next generation help him if he is going to be a cat, a dog or a tree?
