In this paper, we intend to present an interpretation of Thomas Aquinas's theory of judgment (statement), examining semantical, epistemological and ontological aspects of this theory. Elements of judgment such as concepts, phantasms, predication (combination and division), reflection, affirmation, truth and falsity are explained. The article shows that this interpretation of Aquinas's theory of judgment may contribute to clarify fundamental distinctions (as the distinctions between being, essence and existence) of Aquinas's metaphysics.
