The Problem of the Beginning of the World in the Interpretation of Saint Thomas Aquinas

This paper deals with Saint Thomas’s view of the problem of the world’s beginning, which consists in an alleged contradiction between religious truth about the creation of the world by God and Aristotle’s concept of the eternal existence of the world. According to Aquinas, such a contradiction is apparent, because the idea of creation is fundamentally different from the idea of beginning. The discussion of this issue is divided into three parts. At first, the historical background of the whole problem is presented. Then, Saint Thomas’s solution of the difficulty – included in his book De aeternitate mundi – is briefly discussed. Finally, it is argued that this solution can be inspiring for contemporary theologians.
