Analysis of anselm s ontological argument and

If this is correct, then Anselm's second version of the argument also fails. The targets might be undergraduate philosophy students, and the goal might be to give them some sufficiently frustrating examples on which to cut their critical teeth.

Those who take themselves to have good independent reason to deny that there are any gods will take themselves to have good independent reason to deny that there are God-properties that form a non-trivial collection that is closed under entailment.

Conflating the concept with its object, this gives us the belief that than which no greater can be conceived possesses the property of existing in the understanding. If so, then a being cannot be perfectly just and perfectly merciful.

Anselms ontological argument for the existence of god quizlet

Suppose B is a being that instantiates all the perfections and suppose B doesn't exist in reality. This though, is an open debate in philosophy and it cannot be said for certain whether or not abstract objects exist. From this he concludes that the concept of a being that possesses all such qualities is consistent. However, he identified what he sees as the second ontological argument in Chapter 3 which is not susceptible to such criticism. C: Therefore God must exist in the mind and in reality. The argument in Chapter III is rather different, and in some ways more interesting. Hence Even the Fool believes that that than which no greater can be conceived exists in the understanding. Under suitable assumptions about the nature of accessibility relations between possible worlds, this argument is valid: from it is possible that it is necessary that p, one can infer that it is necessary that p. Broad expresses it: Let us suppose, e. The aim is to construct arguments which non-theists can reasonably claim to have no more reason to accept than the original Ontological Arguments themselves. If that thing than which there is no greater does not exist in reality , then there is in the understanding something which is greater than that thing than which there is no greater. Even among commentators who agree that St. Tomberlin ed.

Chambers, T. Premise Hence There is a being x existing in the actual world such that for no world w and being y does the greatness of y in w exceed the greatness of x in the actual world.

Hence God exists. Trying to support most of these claims merely in order to beat up on ontological arguments is like using a steamroller to crack a nut in circumstances in which one is unsure that one can get the steamroller to move! Malcolm goes on to claim that it is unreasonable to hold that a believer in the Ontological Argument is required to show that his conception of God is sound since, although he may respond to specific claims that the notion of a being than which no greater can be conceived is self-contradictory and defend his definition of God on that ground, it cannot be shown in general that the concept is not self-contradictory.

Descartes attempts to prove God's existence by arguing that there "must be some one thing that is supremely good, through which all good things have their goodness". Accordingly, the trick is to show that a maximally great being exists in some world W because it immediately follows from this claim that such a being exists in every world, including our own.
