The Aquinas’s paths of thinking about predestination in the Summa Theologiae

In this paper the method of investigation of paths of thinking is applied to analyse St. Thomas Aquinas’s question 23 on predestination from his Summa Theologiae to show how he reached his conclusions, what influenced his thought and what is the status of his statements. It reveals before all that, despite following the lines of St. Augustine (what can be said about the main conclusions), he designed original paths of thinking, often based on logically correct deductive reasonings, starting from carefully chosen statements (sometimes axioms) and creating together a logically combined network.
