Summary |
With respect to rational (or natural) theology, Kant is best known for his criticism of the ontological proof for God's existence in the Ideal of Pure Reason (though he had already formulated this counter-argument in the pre-Critical period). While Kant also offers criticisms of cosmological and physico-theological (i.e., from design) proofs for God's existence, the notion of a supreme being, whether as an ens realissimum or as a practical postulate, plays an important role in Kant's mature thought. |
