Omnipotent, omniscient etc

20

On behalf of the fool

21
Q

What analogy did Gaunilo use to criticise the OA?

A

The perfect lost island analogy

22
Q

Island analogy as a syllogism?

A

P1: It is possible to conceive of the most perfect and real lost island
P2: It is greater to exist in reality than to exist only in the mind
C: The most perfect and lost island must exist in reality

23
Q

What is reductio ad absurdum?

A

Argument to absurdity

24
Q

What is Gaunilo suggesting about Anselm’s argument?

A

His argument can be used to prove the existence of an endless number of perfect objects

25
Q

Finish the quote: God cannot be conceived not to exist …. That which can be conceived not to exist

A

is not God

26
Q

Criticisms of Island analogy?

A
  1. An island is a contingent thing
  2. It is impossible to quantify the idea of a perfect island
  3. Your conception of the perfect island may change over time
27
Q

Anselm’s second argument as a syllogism?

A

P1: God is that than which nothing greater can be conceived
P2: The greatest conceivable being cannot be conceived not to exist
C: God alone is a necessary being - God cannot not exist

28
Q

Whose version of the Ontological argument was Kant criticising?

A

Descartes

29
Q

What was Descartes’ definition of God?

A

God is ‘the supremely perfect being’

30
Q

Explain this quote: Existence can no more be separated from the essence of God than the fact that its three angles equal two right angles can be separated from the essence of a triangle

A

A triangle has 3 sides with 2 equal right angles cannot be disputed

In the same way God cannot be disputed

31
Q

Explain Kant’s first criticism: Existence is not a predicate

A

Real predicates give us new knowledge of a subject. Exists tells you nothing of the existence of ‘it’

32
Q

Kant’s first criticism: Existence is not a predicate - what example did he use?

A

Thalers - a coin used during Kant’s time. Real predicates would be ‘bronze, round, metallic’

33
Q

Kant’s second criticism: God exists necessarily - explain

A

God exists necessarily is logically true but doesn’t mean that God actually exists in reality

34
Q

How can we fix the Ontological argument?

A

By adding the word ‘if’ - ‘if’ there is a God then God exists necessarily

35
Q

Strength: Deductive argument

A

Deductive arguments are 100% true if the premises are true

36
Q

Strength: Does not rely on empirical experience

A

Empirical evidence can be flawed/can change and is not always reliable

37
Q

Strength: Aide to faith

A

Karl Barth: OA can help people express their faith

38
Q

Proof: Deductive argument?

A

Deductive arguments are 100% true if the premise is true

39
Q

Proof: A priori?

A

True by definition rather than relying on empirical evidence
