St Anselm's proof of God's existence by Ejezie Bernardino Ugoo



INTRODUCTION
The issue of God’s existence has been a controversial issue among philosophers and non-philosophers alike from the middle ages (scholastic epoch) to the contemporary period. Among those who deny God’s existence include the Atheists, Empiricists, et cetera. For the empiricists, “Esse est percepi”, meaning “To be is to be perceived”. For them, whatever is, must have been perceived by the senses, so, whatever is not perceived by the senses does not exist. Thus, since God for them, cannot be perceived through the senses, therefore, God does not exist.
Nevertheless, many other philosophers believe in God’s existence and some of them made meritorious attempt to prove it rationally. Among these philosophers were Saints Augustine, Anselm, Thomas Aquinas, Bonaventure, et cetera. These scholastics were outstanding in their philosophical and theological thoughts on the existence of God. Such thoughts include the teleological argument, cosmological argument, ontological argument, et cetera. Thus, this paper seeks to present and appraise Saint Anselm’s Ontological Argument for the existence of an all perfect God, its criticisms and his reply. Prior to that, we shall consider briefly his biography to give a clue to his ingenious personality.
SAINT ANSELM- LIFE AND WORK
Saint Anselm, a famous medieval philosopher and a renowned theologian, was born of a noble family at Aosta in Northern Italy in 1033. Against his father’s wishes, he decided to become a monk at the Benedictine Monastery. He eventually became the Abbot of the monastery and was later called to be the Archbishop of Canterbury. He died in 1109. Generally speaking, the thoughts of Anselm is said to belong to the Augustinian tradition. His philosophical goal is concerned with providing rational support (rationes necessariae) for the doctrines of Christianity, which he already accepted as a matter of faith. He holds that one should first of all believe certain truths by faith and then try to penetrate these mysteries of faith with reason. This gave rise to the saying, “Credo ut intelligiam” which means “I believe in order that I may understand”. Like his predecessor, the great African doctor, Saint Augustine, he was particularly concerned with using dialectical method to providing rational support to the doctrines of the Christianity and for defending the Church. Interestingly, this merited him the title “The father of Scholasticism” (Pater Sacrum).
Also, Saint Anselm’s popularity in the history of thought lies in his famous and celebrated Ontological Argument for the existence of God, which appears in his work entitled Proslogion. Prior to this work, he formulated three other arguments in an earlier work called Monologion. These three arguments show his overall philosophical orientation namely, his acceptance of Realism and his rejection of Nominalism. Stated briefly, his three early arguments are these;
People seek to enjoy what they consider good and they compare things to be good in relation to a Being which is good-in-itself and consequently, such is the supreme God.
Everything that is, exists either through something or by itself. Obviously, it cannot come out of nothing, for out of nothing comes nothing (ex nihilo nihil fit). Thus, there must therefore be one thing that alone is from itself and that, causes all other things to be and this is God.
There are various degrees or levels of being, whereby animals have a higher being than plants, and people have a higher being than animals. Using this line of reasoning, Anselm concluded that unless we continue to move up through an infinite number of levels, we must arrive at a highest and most perfect being, than which there is none more perfect.
The later work, Proslogion, contains the famous Ontological Argument for the existence of God, which he developed following the request of his contemporary Christian brethren. In proving the existence of God, Anselm distinguishes himself from other philosophers; in that, other philosophers argued from the creatures to God but Anselm argued from God to creatures.
THE ONTOLOGICAL ARGUMENT FOR THE EXISTENCE OF GOD
Saint Anselm’s Ontological proof for God’s existence proceeds from the idea of God as a reality or as existent. This argument attempts the method of a priori proof that uses intuition and reason alone which can be presented in a syllogistic form to prove God’s existence. Anselm starts with a definition of God, or necessary assumption about God’s nature. Thus, his argument states;

I have within my understanding, an idea of God,
This idea of God is the idea of a being that is the greatest that can be conceived.
A being is greater if it exists in reality than if it exists only in the understanding.
If God (the greatest conceivable being) exists in the understanding alone, then a greater being can be
  conceived, namely one that also exists in reality.
So if I have an idea of the greatest conceivable being, such a being must exists both in my
  understanding and in reality;
Therefore, God exists in reality.[1]
Now, we believe that God is that which no greater can be thought (aliquid que nihil maius cogitari posit). Thus, He is the greatest conceivable being. The question then is; does the greatest conceivable being really exist in reality?  However, if such a being does not exist in reality but only in ideas; we could conceive still, a greater being which does not exists simply mentally but in extramental reality. A being that exists in reality is greater than a being that exists only as an idea in the mind. But we cannot imagine something that is greater than God, for it is a contradiction to suppose that we can imagine a being greater, to the greatest possible being that can be imagined. If follows then, that the idea of God as absolute perfection is necessarily the idea of an existent being. Therefore, the Supreme Being greater than which it is impossible to think of any other, necessarily exists in reality.
Furthermore, Saint Anselm argues that it is not possible even to imagine God as not existing; for him, “one who denies God’s existence is guilty of plain contradiction”, it is only the fool (insipiens) who has said in his heart; there is no God above (cf. Psalms 14:1); for when the fool hears the words “the greatest conceivable being”, he understand what he hears, and what he understands can be said to be in his intellect. But it is one thing for something to be in the intellect; it is another to understand that something actually exists. A painter, for example, thinks in advance what he is about to portray. At this point, there is in his intellect an understanding of what he is about to make, though not an understanding that the portrait, which is still to be made, actually exists. But when he has finally painted it, he both has in his understanding and understands it to be in existence the portrait he has finally made. What this proves, according to Anselm is that something can be in our intellects even before we know it to exists. There is then, in the fool’s intellect an understanding of what is meant by the phrase “the greatest conceivable being”, even though the fool does not necessarily understand that this being does in fact exists. It is in his intellect because when the fool hears this phrase, he understands it, and whatever we understand is thereby in our understanding. Hence, even the fool knows that there is at least in his intellect a greatest conceivable being.
Therefore, Anselm asserts that “there exists beyond doubt something than which a greater cannot be thought, both in understanding and in reality”. Conclusively, Anselm thanks God because through His Divine Illumination, he now truly understood that, which through His generous gift, he formerly believed.
GAUNILO’S REBUTTAL
Even though Anselm’s Ontological Argument was considered a classic in his epoch, it was not devoid of criticism. The weirdest antagonist of the argument was a contemporary of Anselm, a Benedictine monk, by name; Gaunilo. He did not want to deny God’s existence but only intended to argue that Anselm had not constructed an adequate proof. Gaunilo in his work; “liber proinsipiente adversus Anselm rationcianationem”, came to the defence of the fool. He argued that the proof is impossible to achieve. It requires that there be in the understanding an idea of God, that upon hearing this word the fool is expected to have a conception of that than which there is no greater. But, Gaunilo says, the fool cannot form a concept of such a being since there is nothing among other realities he experiences from which this concept can be formed. Indeed, Anselm himself already argued that there is no reality like God. Actually, if the human mind could form such a concept, no “proof” would be necessary. To criticize Anselm’s argument, he introduces an idea of the greatest conceivable island we can think of, yet that would not imply that there is any such island in reality, outside the mind.                                               
ANSELM’S REPLY TO GAUNILO
Firstly, Anselm said that we, along with the fool, are able to form a concept of the greatest conceivable being. We do this whenever we compare different degrees of perfection in things and move upward to the maximum perfection; than which there is no more perfect. Secondly, he thought Gaunilo’s reference to a perfect Island showed that he had missed the point of the argument. Anselm replied that the two cases are not the same; the idea of the most beautiful Island does not necessarily imply its existence since it is not an absolutely perfect being. However, the idea of God, according to Anselm is one of an absolutely perfect being which involves existence, and in God alone is essence and existence Identical; since if He does exist, it would not be an absolutely perfect being. Hence, it is a contradiction to posit such argument. An Island does not have to be, it is a contingent kind of being. This would be similarly true of every finite thing. There is only one thing which everything else was, its being is not derived from anything else, but has its existence necessarily from itself; that thing such Being is God.
THOMAS AQUINAS' CRITICISM
While Saint Thomas Aquinas (1224-1274) believed that God’s existence is self-evident, he rejected the idea that it can be deduced from claims about the concept of God. Aquinas argued plausibly enough, that not everyone who hears this word ‘God’ understands it to signify something than which nothing greater can be thought, seeing that some have believed God to be a body. The idea here is that, since different people have different concepts of God, this argument works, if at all, only to convince those who define the notion of God in the same way. From my perspective, the problem with this criticism is that the Ontological Argument can be restated without defining God.
EVALUATION AND CONCLUSION     
From the foregoing, there is no doubt that Anselm’s Ontological Argument is a convincing one. The argument proposes to show that we can deduce God’s existence from the very definition of God; God is that than which no greater can be thought, consequently, He is the highest God, Who needs no other but is needed by all else.
Conclusively, though Gaunilo, Aquinas, Kant and other philosophers criticized Anselm’s argument; other philosophers like Bonaventure, Leibniz, and Descartes supported it. So, in the history of medieval philosophy, Anselm has attained a status quo by the fascinating and all time honored argument; and his ingenuity has earned him the title “the father of scholasticism”.
