Similarity's and Differences
Written in the 16th century Descartes shares some similarity's with Anselm in his ontological argument, both are a-priori and both view existence to be greater than none existence.The arguments however differ on a few key ideas. Descartes avoids a logic leap made by Anselm by describing God as the greatest possible being , this is opposed to describing God as an idea of which Anselm does and as a result runs into the problem of jumping from concept to reality in his conclusion.
The arguments also differ in how they relate god and existence. Anselm sees existing (verb) as something that God does while Descartes sees existing (predicate ) as a quality that God possess.
The Argument
- God is the supremely perfect being.
- The supremely perfect being has all perfections
- Existence is a perfection
- Therefore God exits necessarily
Language Problems
When we say the adjective 'young' we use it to say that x object possesses the quality of youth.
An adjective derives from a quality possessed.
When we write
God exists
It is undisputed that God is an (abstract ? ) noun and the subject of the sentence
However is 'exists' a verb or a predicate ?
Descartes writes from the perspective that existing is a quality that God has rather than something that he does. The problem with this is that just because God possesses existence, it does not mean that is is performing the actual act of existing.
