Offers the reader more aids, including notes and commentary, than any other translation; The subject of this treatise is the nature of being, in God and in creatures, a subject which turns out to embrace a wide range of central metaphysical questions, such as, according to Thomas Aquinas, the existence of God can be proven to be five in number, and these are his most famous Five Ways. The first way to prove that God exists is to consider the fact that natural things are in motion. According to Thomas Aquinas, there must be a prime mover. If the first engine does not exist, there would be no other engine and nothing would be present. He thinks that Aquinas is trying to show that the human intellect is our only substantial form, but Thomas actually rejects this view in a.77.1. Instead, Thomas argues that the human intellectual principle is our substantial form. He argues that this is our only substantial form a few questions later, in a.76.4. Thus, Gilson is correct in stating that Aquinas, moving from existence to essence, uses "evidence for the existence of God to form a notion of his essence." » p. 57 2002, p. 51 and thus correctly lists the proofs for the existence of God under the general heading “On the Essentiality of the Divine Substance” p. 52 2002, In other words, the human person is a concrete individual. Then, as a unique and concrete subject, he imbues his existence and every word, action and attitude with uniqueness. The human person as a unique and irreplaceable subject possesses and dominates himself. This understanding of the person highlighted the “concrete I”.
