Streszczenie:
In regard to the cognizability of God two divergent positions are confronted. On the one hand the position of the Catholic Church which teaches that God can by the natural light of human reason be known with certainty from created things. On the other hand the position of postmodern philosophy (basing on the paper of G. Boniolo) which, following Kantian arguments, denies this possibility as transcending the limits of natural reason. It is argued that antifundational claims of the proponents of postmodern philosophy lack their own foundation. Moreover, their criticism of traditional arguments (like those by Saint Thomas Aquinas for the existence of God) does not take into account the historical background of their formulation. For sim ilar reasons it does not harm any present attempt to argue for the existence of God.
