L’originario e la dialetticità del pensiero. Sulla possibilità di un «ritorno a Parmenide» a partire dall’attualismo

The Giovanni Romano Bacchin’s thought, heir to the Paduan metaphysical school started by Marino Gentile, stands as a radical critique of the concept of “immediacy of Being”. The occasion of the comparison with Emanuele Severino’s thought – who instead of this speculative figure intended to be a re-proposition – reveals the need to affirm Being only “dialectically”, with the consequent impossibility of its semantization by opposition to Noth- ing. Finally, the recovery of a (different) form of ontological Parmenidism is constituted through a specific interpretation of actualism, in particular of the dialectic between abstract and concrete logic. This paper indicates the as- sumption that governs Bacchin’s criticism of immediacy, thus restoring the possibility of a discourse about Being (and Nothing).
