Idealism is more Rational than Materialism

[Chas]

It's the thing you lose when you are in a deep coma.

it is apparently lost, though not necessarily. when you look outside in the daytime, you can see the sunlight. you also receive light from stars, but you do not notice it because it is being glared by the sun. similarly in a state of what we call unconsciousness, we still have consciousness but it is being glared making it appear that it is not there. just because something apparently is not there doesn't mean it truly isn't.

That is meaning tortured beyond recognition.

Whatever it is that you're describing, it isn't consciousness.
