Thomas Aquinas's Epistemology and the Role of God In it

Philosophical texts are full of extensive discussions on epistemology. The present paper tries to expound epistemology from Thomas Aquinas's viewpoint and show the position of God in this intellectual system. Therefore, the subject of the position of reason and faith is one of the main issues of this paper. Referring to the Aquinas's works and what has been written about him, it holds that in Aquinas's thought religious propositions have a higher degree of certainty than that which rational ones have. According to him, man cannot learn the truth without referring to revelation.It can be concluded that in Aquinas's thought the belief in God has significance from three aspects: 1.God as the main element of faith. 2. God as the object of knowledge. 3. God as the end of all fields of human knowledge.
