No, "all bachelors are unmarried" is a logically valid tautology. The following is a logically invalid non-sequitur:
The Ontological Argument For The Existence Of God Wrote:Premise 2: If it's possible that a maximally great being exists, then a maximally great being exists in some possible world.
If something is logically possible it does not at all entail that that something exists in any world.
irrational Wrote:and 3 is based on the argument that the maximally great being, as defined by Plantinga, is possibly necessary.
No it's another non-sequitur.
The Ontological Argument For The Existence Of God Wrote:Premise 3: If a maximally great being exists in some possible world, then it exists in every possible world.
If something exists in a possible world it does not at all entail that it exists in all possible worlds. If something is possibly necessary that does not at all entail that it necessarily exists.
