Entry 0251: God's Existence versus God's Actus Essendi
It is well known that the question “Does God exist?” had an affirmative answer before the time of Saint Thomas Aquinas. The discovery of the notion of actus essendi was not needed to put to rest the issue of God’s existence. The historical path of the philosophical demonstration of the existence of God is the historical path of a judgment of existence applied to God.
The issue of the definition of the essence of God in terms of the metaphysical principle of actus essendi, on the other hand, is not only an issue different from the issue of God’s existence, it is also an issue that took a different historical path in its development. Aquinas was indeed able to express the human intellect’s awareness of the real in the technical terminology of the actus essendi, but there is no question that before the discovery of the notion of actus essendi, answers to the question “Does God exist?” had been given in terms of a judgment of existence.
