Abstract

The non-relativistic quantum mechanics offers us conditions to consider at least two possible metaphysical packages, but incompatible between themselves: metaphysics of individuals, and metaphysics of non-individuals. In addition, the standard formalism is compatible with both the ontologies, without the theory being decided for either of them. From this particular kind of situation, the thesis of the underdetermination of metaphysics by physics can be established. Actually, it can be found, among scientists and philosophers, defenders of one, or another ontology, as well as those who do not address the issue, given that theory on its own does not decide. This means that if we make a choice for one of these packages, it will be happing in a metaphysical field, increasing a lot the philosophical discussions about individuality of quantic objects in quantum physics. From a naturalized methodological view, we present the issues from those defend the individuality of quantic objects, and from those, include us, defend non-individuality, focusing two approaches: (i) the ontological one, in which the fail of IIP as individuation principle is discussed; and, (ii) the logical one, in which non-reflexive logics, as well as a quasi-set theory became more suitable for representing the non-individuals. In this paper we stand for the choice of non-individuals ontology becomes more plausible, and should be taken in account seriously, opening up possibilities for ontological pluralism.
