The levels supervening upon elementary particles are not at all emergent or comlex levels of particles.There is no ontological emergence or complexity. Particles remain particles remain particles. Therefore the Space Kaspar Hauser knows everything about every particle but he doesn't know anything else. Dropping down on a planet he realizes there is an (alien) spatial bat and a "What it's like to be a bat" and elementary particles. The particles, the spatial bat, the"What it's like to be a bat" seem to transcend ontologically the cognitive capacities of the Space Kaspar Hauser. 
This guy got the matter-mind supervening upon elementary particles problem...
The levels supervening upon fundamental physics are Kaspar Hauser levels which develop by leaving the dark, empty space capsule far away from the next solar system.
