Abstract

The concept of matter as it is treated in the philosophical systems of Aristotle, Thomas Aquinas, and John Duns Scotus is examined, partly to ascertain the influence which the original Aristotelian concept of matter had on the two medieval thinkers, and partly to determine which of these two thinkers remained more faithful to the original Aristotelian concept. An analysis is carried out of the views of the three philosophers regarding the ontological status of matter; the intelligibility of matter; the issue of the real distinction between matter and form; the role played by matter in individuating composite substances; and its role in defining composite substances and determining their essences. Finally, the views of Aquinas and Scotus regarding the theory of universal hylomorphism and the theory of the plurality of forms are discussed and compared. It is shown that, while most of the Franciscan philosophical tradition up to Scotus's time was far more influenced by Platonist than by Aristotelian principles, Scotus, though a Franciscan, was much closer to Aristotle than to Plato in his views regarding matter. In fact, the few deviations from the original Aristotelian concept found in Scotus's theory can be ascribed to theological concerns. It is argued, furthermore, that Scotus's views on the concept of matter are far closer to the original Aristotelian theory than our analysis shows Aquinas himself to be
