Discussion: Philosophy an Art form rather than science

I don’t make this stuff up. This is directly gleaned from Stuart Hameroff who is a practicing anesthesiologist and ought to know what he is talking about.
I really recommend you revisit Hameroff’s short lecture where he describes an abbreviated explanation of how anesthesia works.

Note that anesthetics bind directly to microtubules and cause unconsciousness while leaving brain function unimpaired.

If that does not suggest a direct connection between microtubules and consciousness, I can’t begin to imagine a better argument.
