What is the basic ontological argument?
P1: God is that than which nothing greater can be conceived (imagined)
P2: That than which nothing greater conceived must exist
Conclusion: Therefore, God must exist
What type of proof is the ontological argument?
A priori
What is the purpose of proof?
1) To provide a complete explanation
2) They appeal to reason, logic and evidence to support a view or an argument
3) To give meaning to phenomena- theists will interpret certain evidence in terms of God rather than anything else
What is an analytic statement?
True by definition. In other words, the conclusion of the proof is contained within the premise. E.g. Roses are flowers
What is an synthetic statement?
A proposition where the predicate is attached to the subject but not contained within it. In other words, the conclusion is not contained within the premise. E.g. Lawyers are wise.
What is a predicate?
What is said about the subject. A quality or property of an object or subject. E.g. The boy kicks the ball
What is a priori?
Independent on experience
What is a posteriori?
Dependent on experience
Strengths of a priori arguments
Weaknesses of a priori arguments
Strengths of a posteriori arguments
- Empirical evidence is open to different interpretations
Weaknesses of a posteriori arguments
What does ontological mean?
Concerned with ‘being’ or ‘existence’ e.g. God’s being
How is the ontological argument differ from all the other classical arguments for the existence of God?
Ontological argument is a priori argument whilst the rest are a posteriori.
What is Anselm First Form argument (Proslogion Ch.2)?
Why does Anselm argues that God’s existence is logically necessary (de dicto) in the above argument?
It is self contradictory to be able to imagine God as the greatest possible being and yet deny that he exists. Existence is a predicate making “God exists” analytic.
Key strengths of Anselm argument above
1) A priori leads to a logically necessary conclusion
2) Descartes supports the ontological argument
3) Believes God is more than imagination
Key weaknesses of Anselm argument above
1) Lacks empirical proof
2) No evidence or experience provided
3) What does it mean by existing in reality and mind?- too vague
4) God is not an object of proof- faith does not rely on evidence - Kant
5) Circular argument
6) It would be contradictory to claim that God is the greatest possible being
What does “I do not seek to understand so that I may believe, but I believe in order to understand”- Anselm?
- Anselm never doubted the experience of God; uses reason to justify a belief
What is Gaunilo criticism of Anselm’s 1st Form argument?
What is the Island Analogy?
Imagine a perfect island but in reality it doesn’t exist. This means that not always your imagination can be in reality.
Gaunilo’s argument conclusion
1) One can have a concept of God but you cannot move from concept to reality
2) Cannot define a concept into existence- you need empirical proof
What is Anselm’s 2nd form (Proslogion, Chapter 3)?
1) God is the greatest being imaginable
2) It is greater to be a necessary being cannot be than a contingent being (can cease to exist)
3) If God exists only as a contingent being, he can be imagined not to exist, then a greater being could be imagined that cannot not exist
4) This being would be greater than God
5) Therefore, God is a necessary being and must exist in reality ( de re necessary being)
Strengths of Anselm’s argument above
For those theists e.g. Anselm & Descartes who believe that existence is a necessary attribute God. Existence is a predicate
