The Ontological Argument Flashcards
(40 cards)
Who created the Ontological argument?
Saint Anselm
Who was Saint Anselm?
He was a monk and then the Archbishop of Canterbury from 1093
What was the name of Anselm’s book?
Proslogion (Discourse on the existence of God)
What does the word “Ontos” mean?
Essence, existence or being
What type of argument is Anselm’s Ontological argument?
Deductive
A priori
What is meant by a deductive argument?
Argument where if the premises are true, then the conclusion must be true.
What is meant by a priori argument?
Argument which relies on logical deduction and not on sense experience
What is P1 of the Ontological argument?
God (by definition) is the greatest conceivable being meaning there is no one in the world better than him.
Why does Anselm believe the first premise is true?
Anselm believes this is just the common sense view of God:
““This is a definition which even a fool understands in his mind, even though he does not understand God to exist in reality.” - The Proslogion
Also can be backed up by the biblical verse “Great is the Lord, and greatly to be praised”
Also it seems fair that people get to create their own definition of God
According to Anselm, something is great if it has great-making qualities.
What is the second premise of the Ontological argument?
It is greater to exist in reality than not to exist in reality implying that there is no point in it existing in imagination.
Why does Anselm believe the second premise is true?
Anselm believes that things that exist in our minds and reality are better than just things that exist in the mind.
Existing in reality is a great-making quality
What is the conclusion of the Ontological argument?
Therefore, as the greatest conceivable being, God must exist.
Why does Anselm believe the conclusion is true?
If the premises are true then so is the conclusion.
A non-existence being can never the greatest if it existed.
So the greatest being must exist and the greatest being is God that means God must exist.
If God didn’t exist, he wouldn’t be the greatest being and so that being wouldn’t be God
Who was the first to critize Anselm’s ontological argument?
A fellow monk, Gaunilo of
Marmoutiers.
Who was Gaunilo of Marmoutiers?
A christian who wrote directly to Anselm and believed you couldn’t come up with a priori argument for God’s existence
What was the name of the book Gaunilo wrote in response to Anselm?
“Reply to Anselm on Behalf of the Fool”
How did Anselm react to Gaunilo’s criticisms?
Anselm appears not to have minded the criticism, since it gave him the chance to emphasize a second stage of his argument in his Responsio; so from early on, Anselm arranged that the Proslogium should appear with Gaunilo’s criticisms attached.
How does Gaunilo structure his argument?
Gaunilo’s attack used a parody of Anselm’s argument. He gave an Ontological Argument for the existence of a ‘perfect lost island’
What is the first premise of Gaunilo’s criticism?
It is possible to conceive of the most perfect and real lost island.
What is the second premise of Gaunilo’s criticism?
It is greater to exist in reality than to exist only in the mind.
What is the conclusion of Gaunilo’s criticism?
Therefore the most perfect and real lost island must exist in reality. (but it doesn’t)
What method of argument is Gaunilo using?
“Reductio ad Absurdum” (Reduces to Absurdity)
What is “Reductio ad Absurdum”?
An argument’s conclusion is so absurd that the argument must be wrong.
What is Gaunilo suggesting by his argument?
He is suggesting in effect that Anselm’s argument can be used to prove the existence of an endless number of perfect objects and so the real fool would be anybody who argued in this way. We can show that a perfect island does not exist, so Anslem’s argument does not work.
