While Anselm's first argument cannot treat existence as a predicate, second can b/c of 'necessary'.
1) God is a supremely perfect being.
2) A supremely perfect being possesses every perfection.
3) Necessary existence is a perfection.
4) T/f, God possesses necessary existence.
5) God necessarily exists.
Maximally great being, only so if exists in every poss world.
Maximal excellence: M.G entails M.E incl. omnipotence, omniscience + moral perf.
1) There is a poss world in which there is a being that is maximally great.
2) If M.G, exists in our world.
3) Being has M.E, as M.G entails M.E.
4) So, there is a omnipotent, omniscient and morally perfect in our world.
5) There is a God.
Obj to this: We are still only looking at the possibility, nothing in actuality. - Maximal excellence possible.
Anselm used 'exist' wrongly. Can't be predicate. Can be given to fictional things as well.
1) Donkey's exist.
2) Eeyore is a donkey.
3) Eeyore exists.
- Quite unsuccessful.
- Definitions limited - say things in terms of the possibility, not real.
- Difficulty in establishing definition for God - limited to finite human terms not adequate to describe God.
