The positions of Christian Wolff and Im­manuel Kant on the possibility of proving the existence of God require some examination. Wolff’s critique of the physical-theological proof and his proposed ways of improving it are here analysed. God is central to Wolff’s philosophical system and the fundamental prerequisite of his theoretical and practical philosophy. Although Wolff insists that the natural law is inherent in human nature and can therefore be comprehended by human reason without turning to divine revelation, in reality God (...) is the creator of this natural law and the cause of its perfection. Accordingly, faith in the true God in Wolff’s philosophy is obligatory for achieving the supreme degree of virtue, whereas pagans and atheists can achieve only its lowest degree. Kant criticises traditional proofs of the existence of God both in his pre-critical and critical periods. The author looks at the role God plays in Kant’s practical philosophy. Comparing the positions of Kant and Wolff, the author finds many similarities between them. Chief of them is that although both thinkers saw the moral/natural law as universal and obligating regardless of a person’s faith in God, in fact faith in God turned out to be an inevitable consequence of the true moral attitude of the individual.
