Thomism: Philosophical views inspired by Thomas Aquinas, who synthesized Christian thought with Aristotelian philosophy. Thomism is strongest among Roman Catholic thinkers and is characterized by a confidence in natural theology, though it also includes a strong affirmation that some Christian truths can only be believed on the basis of faith in a special revelation. In general the Thomistic tradition believes that "grace presupposes nature and perfects it."1
