A link to
BBC Radio 4's In Our Time was
posted in the Unbelievable? Facebook group, as it dealt with the
Ontological Argument for the Existence of God. In a fit of snarky dismissal I posted the following comment:
This was followed by some disingenuous (I felt) puzzlement, which led me to expand on my remark:
Yet further responses asserted I was wrong about this, and suggested I should deal with the premises of the argument — something I felt disinclined to do at the time, given that attempts were being made to shift the burden of proof on to me by mere assertion.
Nevertheless I stand by what I posted, and in case anyone's still interested here's how I deal with said premises. The ontological argument goes like this (from
Wikipedia):
- Our understanding of God is a being than which no greater can be conceived.
- The idea of God exists in the mind.
- A being which exists both in the mind and in reality is greater than a being that exists only in the mind.
- If God only exists in the mind, then we can conceive of a greater being—that which exists in reality.
- We cannot be imagining something that is greater than God.
- Therefore, God exists.
Premise 1 is fine as far as it goes — you can conceive of God any way you want. But is it really possible to conceive of ultimate greatness? I think not, other than as a label for what is frankly an inconceivable nebulosity. Can you, for example, conceive of infinity? You can have the idea in your mind of a very big number, a number so big that there isn't any number above it — but can you hold that concept in your mind as a number, rather than as a label for something that is, in actuality, inconceivable? Saying — in the
St. Anselm formulation — that
God is a being than which no greater can be
conceived is of no use because you can't actually conceive of even that. You can give it a label, but it's a label that cannot be attached to anything.
So the ontological argument falls at its first premise, proving only that it is — as it has always been — bollocks.
