Graham Oppy, who elsewhere expressed that he "see[s] no urgent reason" to depart from the traditional definition,[2] defined ontological arguments as those which begin with "nothing but analytic, a priori and necessary premises" and conclude that God exists. Craig argues that an argument can be classified as ontological if it attempts to deduce the existence of God, along with other necessary truths, from his definition. In Chapter 2 of the Proslogion, Anselm defines God as a "being than which no greater can be conceived."[1] While Anselm has often been credited as the first to understand God as the greatest possible being, this perception was actually widely described among ancient Greek philosophers and early Christian writers.[19][20] He suggests that even "the fool" can understand this concept, and this understanding itself means that the being must exist in the mind.
