QM mechanics solves mathematically the white rabbit problem. I do
agree with this, but to say it does this by invoking primitive matter
does not follow. On the contrary QM amplitude makes primitive matter
still more hard to figure out. Primitive matter is, up to now, a
metaphysical notion. Darwinian evolution can justify why we take
seriously the consistency of our neighborhood, and why we extrapolate
that consistency, but physicists does not, in their theories, ever
postulate *primitive* matter.

Are you defending Bohm's Quantum Mechanics? The wave without particles
still act physically, indeed they have to do that for the quantum
disappearance of the white rabbits.
