Abstract
This article investigates an aporia in the metaphysical thought of John Duns Scotus. On the one hand, there are strong textual grounds for saying that according to Scotus the subject matter of metaphysics excludes logical being. On this reading, metaphysics would be a transcendental, but not a supertranscendental, science. On the other hand, there are strong textual grounds for saying that according to Scotus the subject matter of metaphysics includes logical being. On this reading, metaphysics would be a supertranscendental, and not just a transcendental, science. Two possible paths for resolving this aporia are considered and subsequently problematized. The aporia seems to be genuine, and recognition of this fact brings into sharper focus the position of Scotus’s metaphysics in the development of supertranscendental thought.
