 The Transcendental Dialectic’s “Ideal of Reason” contains the best known and most frequently anthologized components of Kant’s philosophy of religion. In addition to its portrayal of the ens realissimum, one finds within it Kant’s objections to the Ontological, Cosmological and Physico-theological (Design) arguments. It is thus the text most central to the negative elements of Kant’s philosophy of religion and is integral to the widely held view that Kant is hostile to religion.
