> Agreed - mathematics is predicated on the idea that there are individual things, but as we are learning, through things like quantum field theory, there are no individual things, hence, no individuated 'things' to count.
Even setting aside the absurdities of reducing math to elementary arithmetic, and of reducing arithmetic to counting particular concrete things - claiming to have undermined math with quantum field theory is like writing an essay that argues against the existence of language. "There are no particles, only waves" is not QFT. It's a reasonable position for which QFT arguably offers some measure of support, but that's not even remotely the same thing. QFT is layer upon layer upon layer upon layer of deeply technical mathematics, with a bit of blind symbol-pushing to round out the rough patches.
