We, through our senses perceive a world. This world we try to understand using physics. But these perceptions itself stands on top of consciousness. So consciousness is at least, as real as the world that physics conventionally tries to reason about. It could be even more fundamental, because you can have only consciousness in this universe, but still could sense a whole universe with "things" inside it. But without consciousness, and just a universe with "things", there is no "sensing"...
Point is, physics should include study of consciousness...
There's a difference between making and testing hypotheses, and desperately scrambling to find proof to justify a conclusion made in advance in the face of mounting evidence that said conclusion is false, which is what Penrose is doing regarding quantum consciousness.
Grossly simplifying: he is a dualist, he wants to reconcile his belief in the soul and his physicist's materialist view of biology, so he resorts to putting the source of consciousness in quantum phenomenas, and seeks to prove that they occur in the brain. I disagree that there's an immaterial soul, I disagree that it puppets the material universe through quantum phenomenas, and I disagree that there are important quantum phenomenas in the brain. Most physicists are with me on these.
>source of consciousness in quantum phenomenas, and seeks to prove that they occur in the brain
I think he should look for consciousness as the source of quantum phenomena. Not the other way around. But as he is a physicist, all nails looks like a physics problem.
It is the same situation where people might have struggled to explain the heavenly observation using an earth centric model. Once you invert the wrong premise that you consider as fundamental, the answer, previously so elusive, becomes trivial...
I'm with you regarding opinion on consciousness, but do you think it would be 'better' if there were no dualists and no dualist essays and ideas?
Because I hardly think so.
This is not like alternative medicine where there is harm for people who don't follow the mainstream. And I stress again that Penrose (in the interviews I saw) doesn't actually claim that he absolutely has to be right.
> do you think it would be 'better' if there were no dualists and no dualist essays and ideas?
No of course not, people should be free to discuss and believe in dualism. What I find regrettable, is how often Penrose's name is invoked in an appeal to authority, as if his past (and very valuable) contributions to physics were enough to make him right on everything, including this subject.
Ultimately, I believe dualism is wrong, and I believe I have good reasons to think so. My previous comment was simply my attempt at deconstructing Penrose's argument, participating in the ever-ongoing popular debate.

That may be so, but just the mention of Penrose's name in the context of something else caused you to start a whole subthread that had nothing to do with the subject.
It's statistics that emerges with very high probability due to the law of large numbers. If you calculate 1+1=2 with 100% probability, then quantum physics doesn't meaningfully participate in your reasoning, not more than brownian motion.
You know, I pooh poohed his theories. Still do in sum. But there’s a there there that’s building.
Damn Deepak Chopra and his ilk of idiots for making any conversation of quantum mechanics and biology tinged with pseudoscience. Hopefully we’ll keep getting experimental evidence as we go that it’s not at all absurd to consider quantum effects in biology.
That said, those effects are going to look nothing like sustained coherence for long periods of time.
If they were otherwise reasonable that might be a solution but their obsession with immigration is getting worse. In get the feeling they are turning into into Restore. Maybe next time they will accept a donation from Musk.
And if you thought the GitHub actions hybrid mix of JavaScript templates embedded in yaml was a nightmare, I have bad news for you with respect to ADO pipeline configuration documents...
Yeah I went through hell migrating everything from ADO to GH Actions a year or so ago and even after all this I'm not even slightly close to wanting to go back
I quite like the traingular-tiled graphic of buckminster fuller in the hero section, and that hover highlights the tiles. All very buckminster fuller-y!
