Abstract

Saint Thomas Aquinas explains how is it that there must be among sciences one which is the most perfect and orders all of them, and that may be therefore trully called wisdom. This science has for its object the common entity and studies simultaneously the first causes, the most universal principles and the separated substances. Aquinas sustains that this science receives three different names: theology or divine science, for it treats separated substances; metaphysics, for it studies the entity and the transphysical things that follow it; and first philosophy, for it studies the first causes of things.
