Abstract

In addition to the above Aquinas notes that there are other objects of theoretical knowledge that do not depend on matter for their being, since they can exist apart from matter. Some of these are never found in matter, such as God or an angel. Others, such as substance, quality, being, potency, act, the one and the many, etc., exist in matter in certain cases although not in others. The fact that such objects exist without matter in certain instances suffices to establish Thomas’ point here, that they do not depend on matter in order to exist. Such objects, therefore, those that do not depend on matter for their being, will be treated by a third theoretical science, sometimes known as theology or divine science, sometimes as metaphysics, and sometimes as first philosophy.
