Rosmini e Heidegger. Trascendentalità dell'essere e differenza ontologica

A comparison between Rosmini and Heidegger is apparently bizarre, since the two thinkers had no direct or indirect link. Notwithstanding, it is appropriate and meaningful to point out that in Rosmini's ontology- even though so different from Heideggerian ontology with respect to the metaphysical structure it outlines - there is an explicit attestation of the figure of "ontological difference" ["differenza ontologica"]. By highlighting analogies and differences in the approach of this issue and in the characterization of this notion, this paper will try to outline the main traits of the two proposed ontological models. We will thus be able to compare the essential features of Rosmini's ontological investigation (as a paradigmatic model of metaphysics of transcendence), not only with Heidegger's different ontological model but also with his interpretation of tradition as "ontotheology".
