What are ontological arguments?
arguments about the existence of God based on the definition or qualities of who God is
St Anselm’s Proslogion
What is chapter two’s argument?
- God is the most perfect being
- uses the analogy of a painter - you can imagine painting but unless you paint it you are not a painter - the painting is only valuable if it is real
St Anselm’s Proslogion
What is chapter three’s argument?
- God is a necessary being - God must exist because he cannot not exist
- everthing that we come to think of goes into one of four categories:
1. possible to be
2. possible not to be
3. not possible to be
4. not possible not to be - God is the greatest concievable
- you cannot concieve of God not existing
What is Gaunilo’s ‘perfect lost island’?
- instead of God he asks us to imagine a perfect lost island, one that is completely perfect in every way
- the island must posses the quality of existence, because as Anselm argued his makes something greater than something existing only in thought
- however we know it doesn’t exist as we cannot think something into existence like Anselm tries to do
- God connot be thought into existence so Anselms argument does not prove that God exists
How did Anselm respond to Gaunilo’s perfect lost island criticism?
- God is not contingent on the existence of anything else and therefore Anselm’s argument is only applicable to God
- the concept of an island itself is not perfect or greatest whereas the concept of God itself is
What does Anselm say God is?
‘God is the greatest conceivable being’
What does Descartes say God is?
‘God is a supremely perfect being’
What are Kant’s two arguments?
- existence is not a predicate - predicates add to our understanding of what something is or what is doing
- accepting the definition of God as being either supremely perfect or greatest being does not mean God actually has to exist
What does Descartes say existence is?
a defining predicate
What is something necessary?
A proposition that could not possibly be false
What is something contingent?
A proposition that happens to be true but might have been otherwise false
What is an analytic statement?
A statement that is true by the meaning of the words used
What are synthetic statements?
Statements whose truth or falsity are determined by sense experience
Are ontological arguments a-posteriori or a-priori?
A-priori
