Deck 11: William Rowe: an Analysis of the Ontological Argument

Question 1

In this reading we encounter St. Anselm's ontological argument for the existence of God and Gaunilo's reply. The argument goes like this: God is by definition "a being than which nothing greater can be conceived." If God, the greatest being that can be conceived, exists only in our minds, then there must be a being greater than God-that is, a God that exists in reality (an existing being is greater than an imaginary one). But this leads to a contradiction: A being greater than God is impossible. Therefore, God must exist in reality (as well as in the mind). Gaunilo replies that if Anselm's reasoning were sound, we could prove something ridiculous-namely, that the greatest island possible exists in reality.
-According to Rowe, Gaunilo's "greatest island" argument

A) refutes Anselm's argument.
B) seems to be no threat to Anselm's argument.
C) makes a strong case for atheism.
D) proves theism.

Answer 1

B

Question 2

Gaunilo replies that if Anselm's reasoning were sound, we could prove something ridiculous-namely, that the greatest island possible exists in reality.

A) to be a conclusive refutation.
B) incoherent.
C) not to be a conclusive refutation.
D) sound.
