Sum against the pagans is the second large systematic work of St. Thomas Aquinas, an outstanding theologian and philosopher of the medieval West. In total, Aquinat wrote three works of this kind. His first systematic exposition of the Christian doctrine of God and the world can be considered preliminary: these were the Commentaries on the Maxims of Peter of Lombard. The third, most developed system, remained unfinished: The Sum of Theology. The four volumes of Summa against the pagans are a complete, complete and visible exposition of the entire system of theology and philosophy of Aquinatus. The first volume, now offered to the reader, contains the doctrine of God. In the second - the doctrine of creation: about the world and man.
