I read a sci-fi series by Peter F. Hamilton that had a hyper advanced race of aliens called the Silfen that basically treated reality and physics as their play thing. I remember at the end a character asks one where consciousness comes from and the Silfen replied “beats me”. It’s one of those weird things where the physical smashes into the metaphysical. We can poke around with the brain and see how it affects consciousness but I’m not sure if we’ll ever know how a bunch of electric meat can make a feeling like love or a raw quaila such as the color blue.
