Existence of God Flashcards
put simply what is anselms ontological argument
- trying to conceive of a god that doesnt exist is self-contradictory
- the concept of god is a coherent one
outline anselms argment
p1- god is the greatest possible being
p2- it is greater to exist in the understadning of reality rather than in understandong alone
c1- therefore the greatest possibel bein god must exist in the understanding of reality
what is gaunilo’s perfect table example to the argument
- anselsm argument is invalid and can be used to justify absrd conclusions
- we can conceive of the greatest possible island
-and because it is greater to exist in reality and understanding as opposed to just understanding alone - the greatest conceivable island must exist
how does anselm respond to gaunilo
- says that it is a disanalogy
- as god is a unique case
- as he has exiswtence built into his defintion
- you have to add “perfect” to the island, whereas he is not adding anything to god
put simply how does anselm respond to gaunilo
island have no intrinsic maxima
- there is nothing maximal built into an iasland
- whereas in understanding the concept f god coherently, we also understand him to be the greatest conceivable being
what is gaunilo’s other objection (whihc anselm fails to defeat)
- if somehing does not exist it is not great at all
- we are thinking of how great this being would be if it existed
- this does not show that it exists
how do aquinas critique anselm
- anselm thinks that “god exists” is self-evident
- yet we do not know the essence of god
- so we cant just apriori our way to god
formally outline descartes onological argument
p1- i have an idea of god, that is to say, of a perfect being
p2- a perfect being must have all the perfections
p3- existence is a perfection
c1- therefore god exists
why do empiricists dislike ontologival arguments
- as the concluison determines nothing that the premises dont already tell us
- they are just relations between concepts
humes criticims on the ontological argument
- the truth of an objects existence can only be verified aposteriori because its a fact about the world
humes distinctly conceive critiscims
- if we can distinctly conceive of an objects existence than conceiving of its non-existence os not contradtocty in terms
what is the difference between humes fork and ayer’s verification principle
- humes fork claims about the knowablility of tings whereas the verification princcple focuses on the meaningsullness of them
how would descartes potentially repwsond to hume’s ciriticsms
- the synthetic apriori
how does ayer critique the ontological arguments
- apriori arguments just deduce more tautologies
- only clarifies defintions it does not tell us antyhing about the world
- thus a set of tautologies ( an apriori deductive argument) only more tautoligies can be deduced
how does kant object to the ontological arguments
- existence is not a predicate
formally outline Kant’s “existence is not a preicate argument”
p1- if “god does not exist” is a contradiction then “god exists” is an analytic truth
p2- if “god exists” is an analytic truth, then existence is part of the concept of god
P3- eixstence is not a predicate, (something that can be added to a concept)
c1- therefore existence in not part of the concpet of god
c2- therefore “god exists” is not an analytic truth
c3- therefore we cannot deduce the existence of god from the concept of god
c4- therefore ontological arguments cannto prove that god exists
what is the aim of “existence is not a predicate” in defeating ontological arguments
- to show that we cannot deduce the existence of god from the concept of god
put simply what is kants argument
- that if existence cannot change the propoerties than it is not intrinsic
- existence cannot be the property of a thing so therefore it cannot be a necessary property of the thiung
what are the two different claims that anselm makes according to malcolm
- “the greatest possible being, God, must exist in the understadning and in reality”
- “god cannot be conceived not to exist”
how does malcolm respond to gaunilo’s perfect island objection
- a perfect island can be conceived not to exist because its existence depends on other things (it exists contingently)
- whereas god cannot be conceived to not exist because his existence cannot depend on anything else, ontological indepednece (so therefore he exists necessarily )
