> Why not just say, "Human consciousness is ontologically axiomatic," and leave it at that?
I have no need of that hypothesis.
Do you not think humans are conscious?
I think consciousness is a redundant magical word for a bag of things that most mammals do to varying degree.
What's magical about subjective experience? We all have them, they're the basis for having any empirical descriptions of the world.
What does subjective experience mean in this context?
Your own experiences. Nobody else has direct access to them.
That sounds like a measurement problem.
