CRITICISMS + RESPONSES for ontological arguments Flashcards
ALL CRITICISMS PROPOSED TO ONTOLOGICAL ARGUMENT
- Gaunilo’s ‘perfect island’ objection
- Empiricist objections to a priori arguments for existence
> Is it even an argument?
> “god doesn’t exist’ = isn’t a contradiction - Kant’s objection based on existence not being a predicate
- Impossibility of a necessary being
CRITICISM of Anselm’s first argument + explain
Gaunilo’s perfect island
- Guanilo argued you cannot define something into existence
He replaces ‘greatest possible being’ with ‘greatest possible island’ to show its absurdity:
- I can imagine an island ‘that than which no greater can be conceived’
- The concept of the Island exists in our own minds
- If the island ONLY existed in the mind, then one that existed in reality would be greater
- As this island is ‘that than which no greater to be conceived’, according to Anselm it therefore must exist in reality.
- Gaunilo is trying to argue that we can say this island may exist in possibility but it would be ridiculous to say it actually exists
- if Anselm were right we could define anything into existence “the perfect _”
How does Anselm COUNTER Gaunilo’s criticism of his first argument?
- He argues Gaunilo is comparing things of a like-kind which can always be bettered as they’re contingent.
- All objects in the world (e.g. an island) are contingent and so can’t exist necessarily
- God can have necessary existence
- So Anselm created his second argument to counter and display this issue (better to exist necessarily than contingently)
AQUINAS’ RESPONSE: to Anselms second argument
- People cannot know the nature of God and therefore cannot conceive of a God in the way Anselm proposed
- This argument would only be meaningful to someone who understands the essence of God completely
- Therefore his definition of God = unsupported and vague
List all the EMPIRICIST OBJECTIONS TO A PRIORI ARGUMENTS FOR GOD
- Is it even an argument?
- HUME: ‘God does not exist’ isn’t a contradiction
- HUME: the impossibility of a necessary being
EMPIRICIST OBJECTIONS TO A PRIORI ARGUMENTS FOR GOD:
CRITICISM = is it even an argument?
OBJECTION TO DESCARTES ONTOLOGICAL
- He wasn’t even using a form of deduction
- He merely states God’s existence is logically contained with the concept of God itself.
- This is actually an example of using rational intuition
(he’s assigned it to the wrong part of his Intuition and deduction thesis)
EMPIRICIST OBJECTIONS TO A PRIORI ARGUMENTS FOR GOD:
HUME’s CRITICISM: “God does not exist’ isn’t a contradiction
- Ontological arguments claim God must exist because of the definition of God alone
- Making ‘God exists’ an analytic truth
- For something to be an analytic truth it cannot be contradicted
- Somethings contradictory when it cannot be coherently conceived
- e.g. “a triangle has 3 sides” is an analytic truth as we cannot conceive of a triangle that has 4 sides
- Hume believes anything we can conceive of as existent we can also conceive of as non-existent
- THEREFORE, as “god doesn’t exist’ can be coherently conceived, it isn’t a contradiction
- If ‘God doesn’t exist’ isn’t a contradiction then ontological arguments fail to prove ‘god exists’ = an analytic truth (this is what the entire argument relies on)
EMPIRICIST OBJECTIONS TO A PRIORI ARGUMENTS FOR GOD:
HUME’s CRITICISM: Impossibility of a necessary being
HUME FORK:
- existence is something about the world known a posteriori, therefore it is always contingent
- The only necessary things are ones which are true by definition (analytic)
- However, these tell us nothing about the world, (unlike existence)
- Ontological arguments try to argue God’s necessary existence is a priori knowledge (due to the definition of God alone)
- As existence is a posteriori, and the only things that are necessary are analytic, necessary existence crosses the fork.
- THEREFORE according to Hume anything that crosses the fork cannot be considered knowledge and thus should be ‘committed to the flames’
CRITICISM of only Descartes ontological argument:
CLEAR AND DISTINCT IDEAS ARE CIRCULAR:
- Descartes forms a Cartesian circle
- Descartes claims are can be sure of C+D ideas as God wouldn’t allow me to perceive of something Cleary and distinctly if it wasn’t true, as he’s not a deceiver.
- HOWEVER, Descartes claims we can be sure of God’s existence in his onto argument as we have a clear and distinct idea of him
- This is circular reasoning
KANT’s issue with ontological arguments
EXISTENCE IS NOT A PREDICATE
- A predicate must add to the concept of something
- eg. saying ‘X is female’ or ‘X is tall’ (it tells you something about X)
- Existence wouldn’t add anything to the concept of X
- In the same way existence doesn’t add anything to the concept of God
- Saying “god exists” is the equivalent to saying “God is”
- IF IT WAS A PREDICATE the statement “God does not exist” would mean, “There is a God who has the property of non-existence” = this is illogical
- So existence cant be a predicate
- AS Anselm and Descartes both use it as a predicate of God, they don’t succeed in showing God necessarily exists.
RESPONSE to Kant’s argument that existence isn’t a predicate
MALCOLM’s ONTOLOGICAL ARGUMENT:
- Malcolm argued his argument escapes the problem with predicates
- His argument never once uses necessary existence as a predicate, instead he simply just shows why other forms of existence don’t make sense
- Therefore necessary existence is a ‘best fit’ option not a predicate
