“The knowledge of facts is widely dispersed. We want to make use of knowledge possessed by millions of individual people, which they can only use if they are fed signals about the general situation. You can't reverse it you can't possibly concentrate this knowledge. The whole order of international cooperation has been built on such a signalling system, where signals tell you about facts which nobody knows concrete in their totality, and I may add such signals you cannot correct - you can not correct signals which inform you about circumstances you don't know.”
