The cosmological proof considers the concept of an absolutely necessary Being and concludes that it has the most reality. In this way, the cosmological proof is merely the converse of the ontological proof. Yet the cosmological proof purports to start from sense experience. It says, "If anything exists in the cosmos, then there must be an absolutely necessary Being. " It then claims, on Kant's interpretation, that there is only one concept of an absolutely necessary object. That is the concept of a Supreme Being who has maximum reality. Only such a supremely real being would be necessary and independently existent, but, according to Kant, this is the Ontological Proof again, which was asserted "a priori" without sense experience.
