Abstract
.
Sortal predicates have been associated to a counting process, wich acts as a criterion of identity for the individuals they correctly apply to. We discuss in what sense certain types of predicates suggested by quantum physics deserve the title of ‘sortal’ as well, although they do not characterize neither a process of counting nor a criterion of identity for the entities that falls under them. We call such predicates ‘quantum-sortal’ predicates, and instead of a process of counting, we associate to them a ‘criterion of cardinality’. Then it is discussed how they can be formally characterized.
