Since, however, human knowledge begins with the outside of things as it were, it is evident that the stronger the light of the understanding, the further can it penetrate into the heart of things. Now the natural light of our understanding is of finite power; wherefore it can reach to a certain fixed point. Consequently man needs a supernatural light in order to penetrate further still so as to know what it cannot know by its natural light: and this supernatural light which is bestowed on man is called the gift of understanding.

Reply Obj. 1: The natural light instilled within us, manifests only certain general principles, which are known naturally. But since man is ordained to supernatural happiness, as stated above (Q. 2, A. 3; I-II, Q. 3, A. 8), man needs to reach to certain higher truths, for which he requires the gift of understanding.

Reply Obj. 2: The discourse of reason always begins from an understanding and ends at an understanding; because we reason by proceeding from certain understood principles, and the discourse of reason is perfected when we come to understand what hitherto we ignored. Hence the act of reasoning proceeds from something previously understood. Now a gift of grace does not proceed from the light of nature, but is added thereto as perfecting it. Wherefore this addition is not called "reason" but "understanding," since the additional light is in comparison with what we know supernaturally, what the natural light is in regard to those things which we know from the first.
