“One may be tempted to assume that whenever we ask questions of nature, of the world there outside, there is reality existing independently of what can be said about it. We will now claim that such a position is void of any meaning. It is obvious that any property or feature of reality ‘out there’ can only be based on information we receive. There cannot be any statement whatsoever about the world or about reality that is not based on such information.
It therefore follows that the concept of a reality without at least the ability in principle to make statements about it to obtain information about its features is devoid of any possibility of confirmation or proof. This implies that the distinction between information, that is knowledge, and reality is devoid of any meaning." Anton Zeilinger (Quantum Physicist)
