Remarks on quantum ontology

Despite the discrepancies between quantum objects and `classical' ones, mai nly with regard to the fact that the latter may be thought of as `individua ls', contrary to the former, we still regard the quanta as `things' in our ordinary discourse as well as in the logico-mathematical basis of quantum t heories. This paper considers some possibilities for accomodating the logic o-mathematical framework of the theories which deal with such a strange ont ology where the inhabitants are things devoid of identity and both having a nd not having certain properties.
