In the history of the reception and interpretation of the metaphysics or the “First Philosophy” according to Aristotle, the contribution of authors like Thomas Aquinas and John Duns Scotus is nowadays well known. However, in those conceptions which tend to conceive metaphysics as or to ground it on a theory of transcendental concepts, understanding that discipline then either as onto-theology or as ontology, the contributions of Henry of Ghent and Master Eckhart are still little known. The present study focuses on (...) the doctrine of transcendentals of these two authors, with a particular interest on the influence of Henry of Ghent over Duns Scotus. KEY WORDS – Henry of Ghent. Master Eckhart. John Duns Scotus. Metaphysics. Object of Metaphysics. Transcendentals. Knowledge of God. (shrink)
