> You lose [consciousness] when you’re under general anesthesia or in dreamless sleep. How does he know that? Seems like a petty thing to argue about. But musing about consciousness is so subtle and evasive that you really have to be careful about how you think about it. And this seems like sloppy reasoning to me. Of course you could introduce that as an axiom. But then you still have to either strictly stay in a philosophical domain or you have to map this axiom to something you can measure and identify in reality. And I don't think you can look at an MRI or sth like that and say - see this is the specific measurement I interpret as "not being conscious". I firmly believe there is no point in even trying to figure out consciousness without having significant experience in zen meditation.
