Ontologie neofreghiane: le origini e gli sviluppi più recenti

Résumé

In the present contribution I would like to examine some theories of the ontology of abstract entities that take inspiration from the deep insights of Gottlob Frege.These theories develop in full details some ideas explicitly or implicitly articulated in Frege’s works and try to defend a sophisticated version of Platonism about abstract entities. The review of such theories should allow us to cast light on their merits and their possible flaws and, moreover, to determine which of them is the more promising justification of such Platonism.
