1.1 Possible worlds
1.2 Maximal greatness

2. Alvin Plantinga's version

1. It is possible that a maximally great being (God) exists.
2. If it is possible that a maximally great being exists, then a maximally great being exists in some possible world.
3. If a maximally great being exists in some possible world, then it exists in every possible world.
4. If a maximally great being exists in every possible world, then it exists in the actual world.
5.If a maximally great being exists in the actual world, then a maximally great being exists.
6. Therefore, a maximally great being exists.

3. The argument examined
3.1 Epistemic vs. metaphysical possibility
3.2 Coherence of a maximally great being
3.3 Parodies of the argument
