Anselm provided the first ontological argument for the existence of god in the late 11th century in his proslogion, arguing that god must exist if we can conceive of him in the mid-17th century rene descartes provided his own version of the ontological argument in meditation 5. Criticisms of anselm's ontological argument anselm of canterbury is most famous for his ontological argument for the existence of god, which is that god is the greatest necessary being that which may be thought of (paraphrase. Anselm's argument is circular and is based on assumptions his argument began with an assumption that god exists when the whole point of the argument was to prove god's existence in the first place. Anselm is the most important christian theologian in the west between augustine and thomas aquinashis two great accomplishments are his proslogium (in which he undertakes to show that reason requires that men should believe in god), and his cur deus homo. Surely we must concede, that the existence and non-existence of an object is a qualitative measure of primary importance, and thus, anselm's distinction between an infinitely perfect god that exists as an idea and an infinitely perfect god that exists as reality stands.
One problem with anselm s ontological argument for the existence of god is that it invites parody parallel arguments purporting to prove the existence of any perfect thing at all can be constructed. God is a being with every quality of perfection, including existence because existence is perfection anselm's primary argument is that if one believes a perfect being, god, to exist in the mind, that perfect being must also exist in reality. Anselm's ontological argument purports to be an a priori proof of god's existence anselm starts with premises that do not depend on experience for their justification and then proceeds by purely logical means to the conclusion that god exists. Anselm's existence of god refuted anselm's existence of god refuted if the only proofs for the existence of god were aquinas's five ways and anselm's ontological argument, in my opinion, anselm provides the best reasoning.
This is because the original ontological argument put forward by st anselm and philosophers like rene descartes was refuted by philosophers like david hume and immanuel kant since the original argument assumed that existence was a property. Anselm's ontological argument purports to be an a priori proof of god's existence anselm starts with premises that do not depend on experience for their justification and then proceeds by purely logical means to the conclusion that god exists his aim is to refute the fool who says in his heart. Published: mon, 5 dec 2016 in this paper i will argue that anselm's ontological argument for the existence of god is indeed adequate for establishing the necessary existence of the greatest conceivable being.
Anselm might even view such an axiom as a valid argument that god is therefore infinitely great, and since he is infinitely great than he could only be god which is proof of his existence wretchedly circular reasoning, if i have it pegged correctly. For anselm does not contingently add existence as a property to god and define him into existence naturally these objections are contentious, which adds to the intrigue of the ontological argument previous index next. Anselm formulates 2 ontological arguments for the existence of god anselm's first argument is based on three premises followed by a conclusion the first premise is that god is the greatest conceivable being.
Although anselm's argument for god's existence presented in this article is based on predominately on reason, anselm presents the argument as clariﬁcation christian faith. God's existence contradicts god's non-existence and thus kant's objection fails alvin plantinga restates the argument to demonstrate that nothing is attacked by kant's objection:  1) there is a possible world in which maximal greatness is instantiated. Anselm's ontological argument abstract: anselms's ontological argument is stated, and a few standard objections to his argument are listed st anselm of canterbury (1033-1109) was a neoplatonic realist and was often called the second augustine. Anselm's reply was that it was a mistake to apply his reasoning to argue for the existence of anything other than god, says harwood murdoch applies a modern, more psychological approach: anselm's proof has interested thinkers because it seem so concise and logical. Anselm of canterbury (1033-1109 ad) was a medieval philosopher and theologian, who put forward the celebrated ontological argument for the existence of god.
Therefore anselm believed god's existence to be self-evident, and his ontological argument was the means to prove just that according to aquinas, however, god's existence was not self-evident, and must be proved empirically. It doesn't work kant refuted it you can't argue from an idea to the existence of an idea, since existence is not a predicate anselm says we have an idea of a perfect being and since an idea that exists is better than an idea that doesn't the idea must exist this also stumbles on. During point two anselm uses a definition consistent with, a conceptual god who exists only in the mind, but in point 5 he uses a definition consistent with, a god who exists in reality.
In that anselm builds his argument on the necessary existence of god as the unsurpassable being, the import of the argument is to refute the claim that one can know 2 norman malcolm argues that the argument in proslogion , chapter 2, is a different logical argument from the one in. Perhaps, then, anselm's comparison between a god that exists and a god that does not is possible, and the ontological argument survives kant's criticism whatever you make of the ontological argument, the other arguments for the existence of god are independent of it. Philosophical proofs on the existence of god if you remain in my word, you will truly be my disciples, and you will know the truth and the truth shall set you free —gospel according to st john 8:31-32.
