Ontological argument Flashcards
A priori argument
Gaining knowledge through conceptual truth and definitions instead of experience
Deductive reasoning
Using facts and logic to reach a conclusion.
Contingent
The fact that everything (expect God) depends on something else to exist
Necessary being
Something in which its existence is necessary. Aka God
Anselms original ontological argument
God is the greatest possible being by definition, and therefore in our heads.
It is greater to exist in reality than in the mind
If he is the greatest possible being in only our minds then a greater being can exist in reality.
Therefore he must exist in reality if he is the greatest
Analytic proposition
A statement which is true by definition - Anselm proposes that the phrase “God exists” is an analytic proposition as the concept of existence is part of the concept of God
Anselm quote
“The fool says in his heart ‘There is no God’ “
Gaunilos criticism of Anslem
If we swapped the idea of God with an island, Anselm argument is illogical.
“The lost island”
Eg imagining the greatest possible island must mean that is exists in reality, as for it to be the greatest then it must exist.
This clearly is not true, Gaunilo states that using Anselms premises anything could be proved to exist.
Anselms 2nd ontological argument
You can’t compare an island to God, as an island is a contingent being and God is a necessary being.
Existence isn’t a necessary part of an island, but it is for God
(Analytic statement)
Descartes
- God is a perfect being
- A quality of perfection is existence
- Therefore God must exist
- Existence is a predicate of God
Kant
- Disagrees with Descartes
- Existence is not a predicate
- To say something exists does not change its definition
- 100 coins example : if your looking at 100 coins, your mind also sees 100 coins. Reality is the same as the mind.
Russel
- Agrees with Kant/disagrees with the ontological argument
- All ontological arguments are cases of bad grammar
- Existence is not a predicate, they have made a linguistic mistake
Aquinas
- Disagrees with the ontological argument
- Humans can’t fully know the essence of God using reason anyway
- Instead we should focus on empirical evidence
Dawkins
- Disagrees with the ontological argument
- Book “God delusion” states that “faith is the great excuse to evade the need to think and use evidence”
Platinga
- Agrees with Anselm + ontological argument
- Supports Anselm’s defence against Gaunillo as an island can be adapted and improved but God can’t be any greater
