PHLA10H3 Chapter Notes - Chapter 8: Ontological Argument, Fathom
Document Summary
A priori truths = propositions that can be known to be true by reason alone. A being who fails to exist in the actual world (while existing in all other possible worlds) is less than a being who exists in all possible worlds. Therefore, god exists necessarily: premise one basically means that god is the absolute most perfect possible being in all possible worlds, note: conceivability is subjective, we can all fathom different things. When aslem talks about god being the greatest conceivable thing, he really means greatest possible thing: also, aslem implies in his argument that a necessary being is more perfect than a contingent one. A p-island is by definition the greatest possible island. An island that fails to exist in the actual world (while existing in other possible worlds) is less perfect than an island that exists in all possible worlds.
