Arguments from reason for the existence of God Flashcards
What book does Anselm’s argument come from
Proslogian
What is significant about Anslems proslogian
Written with the purpose of a prayer expressing love and reason for believing in god, not written as an argument to prove gods existence
What does Anselms argument rely on
Reason and logic, depends on valid premises leading to a reasonable deduction
What is Anselm’s definition for God
A being than which nothing greater can be conceived
What biblical verse does Anselm use
The fool in psalms
In re
in reality
In intellectu
in the mind
What is Anselm’s example to show existence in reality is better than in the mind
A painter can imagine his next masterpiece but it only becomes a great master piece when it is drawn and put into reality
What does Anselm argue is greater existence
things that exist in both the mind and in reality
Explains Anselm’s use of the fool as an example
The fool would agree with Anselm’s definition of god so god exists in his mind there is a universal idea of what a god is. So he always exists in the mind even if some may deny his existence in reality
What is the contradiction Anselm shows in the fools statement
Things that exist in reality are greater than in the mind, so how if the god only exists in the mind as the fool said he cant be the greatest being that can be conceived
Anselms conclusion
God must exist in reality because he exists in the mind and is the greatest being conceived.
Strengths of Anselm’s Ontological Argument
- Anselms definition of God is agreeable for all people
- Apriori argument so is logically and reasonably based
- Valid to say existence in reality is greater than in the mind
Where is the logical fallacy in Anselms argument
In jumping from it being greater to exist in reality to god must exist, leap in logic
Weaknesses of Anselms Ontological argument
- How can we come up with a definition of god
- Aposteriori arguments use better inductive logic
- Existence in the mind is better, like a flying carpet, we can imagine things that don’t exist
What is the fools quote
The fool has said in his heart there is no god
Who criticised Anselms first formulation
Gaunilo
What was Gaunilos book
on behalf of the fool
What part of Anselms logic did Gaunilo disagree with
Having an understanding of something in your mind must lead to it existing in reality
Explain Gaunilos example
You can picture a perfect lost island that no one has ever found, exists in ones mind. Therefore it must exist because it is the greatest conceivable island so exists in mind and in reality
—–> But it doesn’t exist as it is imaginary
Gaunilos conclusion
Anselms reasoning only defines god into existence as can be done with any imaginary concept, it doesn’t prove his existence, just because something is in the mind doesn’t mean it must exist
How does Gaunilo also criticise Anselms reliance on reason
relying on reason alone has no quantifiable evidence of gods existence, difficult to even have an idea of god in the mind
