It absolutely assumes a unitary conscious experience versus what increasingly seems to be the case, a bunch of narratives our brains thread into a cohesive story ex post facto.

Put another way, there very well may be hard limits to how much a human-like consciousness can understand itself.

That is exactly the reality I am asserting, whether or not they actually describe an "external" reality

[JumpCrisscross]

I guess my argument is you can’t be absolutely certain about what your internal reality is. Perception, as a measure, even when pointed entirely internally, is fundamentally fuzzy.

My internal reality I hope tracks external reality.

And what I can be certain about is what my internal reality is.

And if you think I cannot be sure of that, I think I can be certain about I think my internal reality is.

And if you think I cannot be sure of even that, I think I can be certain about I think what I think my internal reality is.

It's perception all the way down, recursively. The reality is result of this taken to infinity.
