Abstract
The problem of the reality of God’s existence was a keynote of the history of Western philosophy. Anyway, the philosopher that could create his own philosophical system always touched upon the concept of God. It goes without saying that every historical period gave its own solution of the problem. The scholastics aimed to justify the provability of the reality of this concept and its deducibility from philosophical categories, while in The Age of Enlightenment, which included the Classical German philosophy, people tried to think of the question “Is there a God?” rationally. Immanuel Kant attempted to analyze the three proofs of God’s existence: ontological, cosmological and physico-theological. These proofs correspond to the specific cognitive abilities of a human. The subject of our article is the criticism of the proofs of God’s existence.
