Le Dieu de l’Opus Postumum entre Zoroastre et le Démiurge platonicien

The conception of the Christian God, as it appears in Kant’s Opus Postumum, is developed between two boundaries, where unique supreme beings pre-Christian can be found, whose representation was significantly influenced by the moral principle: one is Zoroaster, and the other is the Platonic Demiurge. Between these two boundaries, the Christian God of transcendental philosophy evolved through the idea of moral practical reason, because it has the capacity for self-determination, which it uses in evaluating actions according to a principle. Zoroaster influenced the concept of the Christian God through the moral ideal of the unique being, and the Demiurge provided Him with a faculty of knowledge; however, Kant’s transcendental idealism took these suggestions further by placing God within the human soul, thereby creating a foundation for His duties. By highlighting the Platonic influence, I argue for the enrichment of transcendental theology as presented in the Critique of Pure Reason, reaching a cosmo-theology.
