Everything that is in that paragraph is equally relevant to consciousness itself….which Carroll assumes is a direct function of the physics of bio-chemical activity.
…notice the word ‘assumes’. Nobody has a clue as to the phenomenology of consciousness (or even if it has a distinct phenomenology). There are some…such as Cristof Koch…who believe ‘consciousness’ occurs as some manner of fundamental feature of reality. Nor does anyone have a clue as to the direct relationship between the physical activity of the brain and cognitive activity.
I don't think the word or concept called "phenomenology" should be what any of us are talking about if the question is whether evidence from scientific studies supports claims that human conciousness exists independently of the brain.
What Carroll is saying is only what all genuine scientists should say (and it's what Novella also said repeatedly in that debate) - what Carroll "assumes" is that scientifically valid and properly gathered and examined material evidence, is the most reliable method we currently have for determining what is likely to be true vs. what is unlikely to be true.
As Carroll says in the film;- if you reject that scientific procedure and claim to have some better and more reliable way of finding the most likely explanations for any real material event in this universe, then (a) science has shown that you are wrong, and it's shown that literally billions of times over, and (b) you must as your alternative tell us what this other method of "knowing" actually is, and show by proper evidential explanation that your method works better than science.
So what is your un-scientific method for determining what is most likely to be right about such questions as whether the mind functions in the absence of any brain?
