 Kant maintains that underlying all the traditional proofs for God’s existence is the concept of the ens realissimum, the most real being. Reason comes to the idea of this being through the principle that every individuated object is subject to the “principle of complete determination”. While the generality of concepts allows them to be less than fully determined (e.g., our concept of a horse extends over horses that are different colors, heights, etc.), individuated objects must be completely determined (e.g., an individual horse must have specific colors, a specific height, etc.).
