arguments for god based on reason (4) Flashcards
Anselm’s 1st formulation
part of Prologion 2, why he believes God exists. Anselm uses a priori evidence, reason alone to justify God.
definition of God
Anselm defines God as ‘that than which nothing greater can be conceived’. uses Psalm 14:1, “the fool says in their heart there is no God”. non believers are foolish. a painting is greater when it is physically there, God is greater if there
existence in mind/reality
anything that exists in reality is greater than the mind. Anselm says even the ‘fool’ would agree with his definition, universal understanding. anything that exists in reality is greater better- God must exist in reality
Anselm’s conclusion
God must exist in reality and he says ‘fool’ not a believer as cant understand true definition. if you accept definiton, you accept God.
Anselm’s onotological argument justifies belief in God
- most people would agree with definition
- Anselm’s argument is a priori, not influenced by emotions
- it is valid reasoning, God must exist in the real life for him to be greater
Anselm’s onotological argument cant justifies belief in God
- a priori uses invalid logic, may be better use a posteriori arguments like design
- we can disagree with reasoning, there are things that are impossible
- it is difficult to define something we have no knowledge of
Gaunilo’s criticism
disagreed with Anselm’s use of logic. he says it is a false assumption that something must exist in reality cause it exists in u head.
Gaunilo’s greatest island
uses example of a ‘lost island’ nobody has found, Gaunilo can picture it. Anselm claims anything that exists in reality better then the mind, so any island better. Anselm also would conclude it has to exist as better in reality.
Gaunilo and reasoning
says its wrong to rely on reasoning alone as its God we are trying to prove. we can have an understanding on an island as we have seen them, but we have no seen God.
Anselm’s second formulation
responds to Gaunilo. Gaunilo uses an island which is contingent, God is a neccesary being. an island is contingent, able to come in and out of existence whereas God needed. because neccesary greater than contingent.
what was Gaunilo book called
on behalf of the fool
Gaunilo’s crticisms are succesful
- possible to imagine something in your mind and not have it exist in reality
- Anselm defines things into existence.
- Russel says things only important if it refers to an instance of something
Gaunilo’s crticisms are not succesful
- Plantiga supports Anselm, an island has no intrinistic maximum whereas God does. he can always be better.
- this is how a priori arguments work, if you agree with the def you agree with the conclusion
- arguments based on observation also flawed
analytic/synthetic statements
analytic- statements contains truth to verify within itself
synthetic- a statement needs external evidence to verify
kant’s criticism
says all statements about existence are synthetic, need evidence. it is logically neccesary for a triangle to have 3 sides, not for it to exist.
Descartes
said God’s essence includes existence, just like how a triangle must have 3 sides. Descartes says its a contradiction to say he doesnt exist.
real/determining predicate
adds something to the description of something. Kant used example of 100 thalers or silver coins. 100 real coins have no more than thalers, so concept is the same. Kant says existence adds nothing to our understanding, not a predicate. also said coins could by verified synthetically and make a difference.
kant’s criticisms are succesful
- right to argue God needs synthetic verification as ‘God exists’ is not analytic
- existence is not a real predicate as adds nothing to our undrstanding
- definition of a concept does not bring that concept into existence
kant’s criticisms are not succesful
- a priori arguments use reason only,if you follow premises God just exist.
- definiton of God includes the predicate of existence.
- God is logically neccesary, Anselms 2nd formulation proves how it is better than being contingent
Descartes’ defintion
God is a supremely perfect being which contains perfect characteristics. existence is one of the essential characteristics. like the way a triangle cant be taken away from angles. existence is god.
logical fallacies
arguments for God are accused of failing on logical fallacies. may be accused on making assumptions about God’s definition or that existence is a predicate.
Descartes’ ontological argument is stronger
- Descartes defines God as a supremely perfect being which has all perfections
- Descartes argues that existence is part of his essence and inseperable
-uses God as an analytic term- defined in itself
Kant criticises Descartes
- says existence is not a determing predicate as adds nothing to understanding
- possible to reject both concept and definition. we can think of triangles not existing as we can think if God
- God is a synethtic statements- when talking about an instence you need to see evidence of it
Cottingham
suggests arguments fall into the trap of ‘faith seeking understanding’. arguments are formed by those already a believer.
