What is Gaunilo’s argument on gossip as a way of criticising Anselm?
Gossip is unreliable and just because you have it in the mind does not mean it is true in reality
What is Gaunilo’s argument on not being able to define things into existence as a way of criticising Anselm?
You cannot demonstrate the existence of something just by having an idea about it
What is Gaunilo’s island analogy as a way of criticising Anselm?
anyone can think of a most perfect paradise island but this does not mean it exists in reality
How did Anselm respond to Gaunilo?
By claiming that God’s existence is necessary as God is a necessary being
Explain this strength of the OA: it is deductive
if it succeeds it provides 100% proof of the existence of God
