Deus atque id quod fieri potest

Abstract

A-priori reasonings for God's existence by Leibniz are compared to a non-modal argument by G. Mavrodes and to recent modal reformulations of St. Anselm's ontological approach, Leibniz's principle that “if the necessary can be, then it is” and St, Bonaventure's “necessity of contingency” are examined with Kant's pre-critical “foundation of possibility” proof Traditional exemplarism (as in St. Augustine), it is suggested, grounds current and scholastic modal theory, and reflects an integrated world-view at once Christian and philosophical.
