Abstract

Banez’ commentary on I, q. 3, art. 3, is justly well-known for the criticism of earlier Thomists and for its metaphysical acuity. But Banez’ skill is best seen when we read not only his commentary, but the other texts which he himself was reading, such as the works of Capreolus, Soncinas, and Cajetan. In particular, he connects three issues which at first glance might seem unrelated, namely the view that esse is the ultimate act, that it is reduced to the categories, and that it is less perfect than essence. The view that esse is the ultimate act implies that it can be reduced to the category of what is prior to it as the imperfect to the perfect. The position that essence on its own is prior and belongs to a category can lead to the view that essence is more perfect than esse.
