Roger Penrose On Why Consciousness Does Not Compute
The emperor of physics defends his controversial theory of mind.

by Steve Paulson

Quote:He was also jolted by a series of lectures on quantum mechanics by the great physicist Paul Dirac. Like many others, Penrose struggled with the weirdness of quantum theory. “As Schrödinger clearly pointed out with his poor cat, which was dead and alive at the same time, he made this point deliberately to show why his own equation can’t be the whole truth. He was more or less saying, ‘That’s nonsense.’ ” To Penrose, the takeaway was that something didn’t add up in quantum theory: “Schrödinger was very upset by this, as were Dirac and Einstein. Some of the major figures in quantum mechanics were probably more upset than I was.”

But what, I asked, does any of this have to do with consciousness? “You see, my argument is very roundabout. I think this is why people don’t tend to follow me. They’ll pick up on it later, or they reject it later, but they don’t follow argument.” Penrose then launched into his critique of why computers, for all their brute calculating power, lack any understanding of what they’re doing. “What I’m saying—and this is my leap of imagination which people boggle at—I’m saying what’s going on in the brain must be taking advantage not just of quantum mechanics, but where it goes wrong,” he said. “It’s where quantum mechanics needs to be superseded.” So we need a new science that doesn’t yet exist? “That’s right. Exactly.”

Reminds me of something Pauli once said:

"It is my personal opinion that in the science of the future reality will neither be “psychic” nor “physical” but somehow both and somehow neither."
'Historically, we may regard materialism as a system of dogma set up to combat orthodox dogma...Accordingly we find that, as ancient orthodoxies disintegrate, materialism more and more gives way to scepticism.'

I don't think that quantum mechanics  are able to explain "first person" and the problem with consciousness. The fact alone that we can think over our thoughts seems just too much for it.

Could you explain this?

It's just my idea, but I think consciousness is something different from quantum effects. Supernatural? I don't know, but i think we are very far from even grasping a hint of it.
