Abstract

This study examines the essence of philosophy by Fray Tomas from the distinction between philosophy, physics and theology like has been shown in the book 1, q. 1 a. 1 of Commentary on the Peter Lombard’ Sentences. That distinction intends to define the boundaries between those different disciplines. In this task to specify the limits and distinctions between sciences, it’s become manifest the interrelationship between rational thinking and lighting by faith, from which it seems that the philosophy can be affected by the tension between their two modes of knowing.
