Aquinas' Concept of Form and Matter Are Co-Constitutive Principles

The Thomistic notion of form is merely an archaic philosophical idea that has no real relevancy in our modern scientific era. We are not asking the question here of whether immaterial realities exist. The medieval philosophers spoke of these categories of beings in terms of the quantitative figure or the locative position of a thing, but they did not confuse this with the formal nature of a given thing. It would be painfully naive on our part to think that either ancients like Aristotle or medievals like Aquinas could make the simple mistake of confusingform and reality.
