The Ontological ArgumentThe Ontological Argument, expounded by Saint Anselm in his Proslogium, attempts to demonstrate the existence of God simply by the fact that we have a particular concept of God - that God it is "that than which nothing greater can be conceived." St. Anselm presents a compelling argument that many people consider the work of genius. It is also often considered a failure because, in the words of William L. Rowe, "By admitting that Anselm's God is a possible thing, we are in effect admitting that Anselm's God actually exists." In other words, it “presupposes the point it is supposed to prove,” primarily because it presupposes that existence is a quality that makes one great, and for God to be truly great, he must exist. I disagree with Rowe's point that Anselm's definition of God invalidates his argument because it later helps prove Anselm's argument. I agree with Anselm's assumption that existence is a quality that creates great things. Therefore, I believe Anselmo's argument is valid. There are so many things that help support an argument like Anselm's. You definitely have to consider epistemological questions, or “How do we know what we know?” requests. One must also consider how God should be defined, especially since the definition and concept of God is so central to Anselm's point. I am of the opinion that knowledge is a reasonably and logically supported belief. Knowledge approaches truth, or actuality, but is not necessarily true. I believe that knowledge is the closest thing to the truth that we can get with the information we have access to. Therefore, at the root of all knowledge is a belief supported by other information we believe. So, a belief can become knowledge... middle of paper... be true. Let's take the example of the Fountain of Youth for example. The Fountain of Youth would be bigger (or more powerful) than it would be if it existed. If existence is viewed in this way, then it can be applied to everything, including God. Therefore, if one understands the concept of "that than which nothing greater can be conceived", this is believed to be a definition/concept accurate about God, and accepts the claim that existence is a "great" quality, then one must admit that God exists. Furthermore, Rowe's point that Anselm's definition of God invalidates his argument, because it later helps prove Anselm's argument, is invalid because, as with the freedom example, it can be shown that for some things, the fact that we have particular concepts about them proves their existence. As a result, I continue to believe that St. Anselm has a valid point.
