Hidden matters

[dmm]

Rovelli and Vidotto seem to be saying that it might be that dark matter is simply "Plank sized while holes". I wonder if this would also provide a good enough explanation of dark energy (white holes if they exist would be wonderful sources of all kinds of things, and Plank-sized ones would create this feel that those things "just appear from nowhere", which seems like a nice setup for dark energy).

"Hard problem of qualia". The qualia-related part of the "hard problem of consciousness" is certainly hard. If one can factor out the "qualia problem", I am no so sure that the remaining part of the problem of consciousness is "hard" in the Chalmers-introduced sense of "hard".

So far, almost all provisional "theories of consciousness" just ignore the "hard problem of qualia" (which is why I quite skeptical of them).

The only approaches which seem to make sense are of "provisional dualism" (one provisionally introduces qualia as additional primitives
and build one's theories on top of that; if one admits qualia as primitives, the remaining part might be tractable). I just learned a couple of days ago that Johannes Kleiner made some rather nice progress in that direction in 2019.

Imho, viewing qualia as something magical and not of natural origin contradicts both Darwin's theory and the fact that we grow out of a single cell.
