the ontological argument Flashcards
Who came up with the Ontological argument?
St Anselm of Canterbury (1033-1109)
What does ontological mean?
The word ‘ontos’ means ‘being.’ The Ontological argument thus attempts to prove the existence of God a priori by focusing on the nature of his existence or being.
What is a deductive argument?
A deductive argument is one where the conclusion necessarily follows from the premises – if the premises are true then the conclusion must follow. The validity of a deductive argument depends upon its internal logic – i.e. the very definition of words determines whether or not the argument can hold to be true. A deductive argument can be said to be ‘a priori’ as it does not depend upon external validation.
What is an inductive argument?
Inductive arguments are based on observation. The validity of inductive arguments can vary from 0% to 100% as they are based on empirical observation and not internal logic. Premise (1) and (2) may well be true but the conclusion (3) may well be a massive assumption.
What type of argument is the ontological argument?
It is deductive and it is analytic.
What is an analytic statement?
Analytic sentences are true by definition, and are generally self-explanatory - used in deductive arguments.
What is a synthetic statement?
Synthetic statements, on the other hand, are based on our sensory data and experience. - Used in inductive arguments.
What is Anselm’s first argument for the existence of God?
God is the greatest possible being (that than which nothing greater can be conceived’)
If God exists in the mind alone (only as an idea), then a greater being could be imagined to exist both in the mind and in reality
This being would then be greater than God
Thus God cannot exist only as an idea in the mind
Therefore, God exists both in the mind (as an idea) and in reality.
What does Anslem’s first premise in the first form of the ontological argument mean?
The first premise (1) that God is the greatest possible being stems from the classical attributes of God i.e. omnipotence, omnipresent, omniscience…etc. It naturally follows that there cannot be two rival omnipotent beings…etc. For Anselm (and most theistic thinkers) this understanding of God goes without saying. I. Any other definition of God would not be God.
What do the second and third premises of the first form of the ontological argument mean?
The second and third premises (2 and 3) argue that something that exists in reality is better than something that exists only in ones imagination. For example, which is better imagining that you have £1 million, or actually having £1 million in your bank account?
What does the conclusion of the first form of the ontological argument mean?
The conclusion (4) follows from the first three premises (1,2 and 3). Anselm’s final conclusion (5) is that if all the previous premises are true (1,2,3 and 4) then God must exist
What is an overload objection?
they don’t claim to show where or how the ontological argument goes wrong, they simply argue that if it is sound, then so are many other arguments of the same logical form which we don’t want to accept, arguments which would overload the world with an indefinitely large number of things like perfect islands, perfect pizzas, perfect pencils, etc.
What problem with Anselm’s first form of the ontological argument did Gaunilo of Marmoutiers’ raise?
One problem with Anselm’s ontological argument for the existence of God is that it invites parody. Parallel arguments purporting to prove the existence of any perfect thing at all can be constructed.
What was Gaunilo of Marmoutiers’ argument against Anselm’s first form of the ontological argument?
Gaunilo invited his readers to think of the greatest, or most perfect, conceivable island.
As a matter of fact, it is likely that no such island actually exists.
However, his argument would then say that we aren’t thinking of the greatest conceivable island, because the greatest conceivable island would exist, as well as having all those other desirable properties.
Since we can conceive of this greatest or most perfect conceivable island, then it must exist.
Gaunilo argued that this line of argument was no less absurd than Anselm’s orginal argument. This logic is flawed, thus showing the ontological argument is flawed as a perfect island does not exist.
What is the flaw in Gaunilo argument (How did Anslem respond)
There will be disagreements as to what makes an island perfect
By definition any piece of land surrounded by water is an island. In this case all islands are perfect islands.
Anselm argued that he was not talking about temporal contingent things such as islands which are rooted in time and space. Such things are dependent upon other things for their existence. Anselm is talking about the greatest thing that can be thought. God is not contingent or temporal. God’s existence is necessary
