  The fundamental dimension of transcendental truth as an openness of being in its intelligibility to cognition, which Aquinas had identified in De ver., is also clearly expressed in Duns Scotus’ reflection on truth in his commentary on the sixth book of the Metaphysics. After having declared that all truth related to the divine intellect is studied by metaphysics, he continues to distinguish three senses in which the human mind is related to truth, of which only the first is studied by metaphysics: namely when a thing is said to be true because it is able to manifest itself to an intellect capable of perceiving it, of which Scotus explicitly says that it is convertible with being. The other senses, according to which a thing is true because it is assimilated to or known by the human intellect, fall outside the scope of metaphysics and belong to logic.
