Il vero baratro della ragione: la questione dell'assolutamente necessario in Kant

The paper discusses the Kantian question of the impossibility to determine the necessary being. The aim is to sketch the proper performance of the proofs of God’s existence on reason itself by focusing on the «true abyss» experienced in the absolutely necessary. Their achievement is first shown in the irreducibility of the idea of absolutely necessary to the transcendental concept of God, i.e. the idea of the supreme being; secondly, it is exhibited in the resistance of this idea to being translated on the regulatory side, according to which all three ideas of reason, that is, soul, world and God, have an immanent use.
