  Returning to the core point, one can maintain that quantum objects are individuals, even granted the implications of quantum statistics. And one can either take that individuality to be ungrounded and ‘primitive’ or ground it in some form of primitive thisness or, more plausibly for many, in the associated properties via an updated and extended form of PII (criticisms and concerns notwithstanding). However, there is also the alternative, articulated during the throes of the quantum revolution itself, as noted above, which is to take quantum objects to be non-individuals in some sense. Of course, if this alternative metaphysical ‘package’ is adopted then Leibniz’s Principle simply does not apply. But now the obvious question arises: what sense can we make of this notion of ‘non-individuality’?
