I consider that we are still monkeys; we just came down from the trees rather recently, and it’s astonishing how well we can do. The fact that we can even write down partial differential equations, let alone solve them, to me is a miracle. The fact that we ourselves at the moment have very limited understanding of things doesn’t surprise me at all. […] If you go far enough in the future, we’ll be asking totally different questions. We’ll be thinking thoughts which at the moment we can’t even imagine. So I think to say that a question is unanswerable is ludicrous. All you can say is that it’s not going to be answered in the next hundred years, or the next two hundred years… To say there are unanswerable questions makes no sense. But if history comes to a stop, if we descend into barbarism or if we become extinct, then the questions won’t be answered. But to me that’s just a historical accident.
