A common objection to the ontological argument is the fact that we can think of something does not prove that it exists. What would be Anselm's response to this objection?
B)How is Anselm's 1st ontological argument (given in chapter 2, last paragraph, page 149) different than his 2nd ontological argument (given in chapter 3, 2nd paragraph, pg. 150 of The Originals)?
