From the BBC:
"I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem." The American physicist Richard Feynman said this about the notorious puzzles and paradoxes of quantum mechanics, the theory physicists use to describe the tiniest objects in the Universe. But he might as well have been talking about the equally knotty problem of consciousness. Some scientists think we already understand what consciousness is, or that it is a mere illusion. But many others feel we have not grasped where consciousness comes from at all.
Here is the article from which this is the opening paragraph: http://www.bbc.com/earth/story/20170215-the-strange-link-between-the-human-mind-and-quantum-physics
Would anyone like to contribute comments on this?
