Abstract

Recently, Simon Saunders has applied Quine's account of discernibility to the theory of identical particles, ultimately to argue (with Muller) that quanta (bosons and fermions) can be weakly discernible. I want to expand on this work along two axes. First, to explain how the results apply to higher kinds of statistics -- 'quarticles'. Second, to dispute the claim that quanta are weakly discernible: I question whether the operators used to discern the particles do not represent the properties that they are claimed to.
