The ontological proof for your existence.
1. It is proposed that a being has minimal excellence in a given possible world W if and only if it is utterly pathetic, absolutely stupid and wholly terrible in W; and
2. It is proposed that a being has minimal greatness if it has minimal excellence in every possible world.
3. Minimal greatness is possibly exemplified. That is, it is possible that there be a being that has minimal greatness. (Premise)
4. Therefore, possibly it is necessarily true that an utterly pathetic, absolutely stupid and wholly terrible being exists.
5. Therefore, it is necessarily true that an utterly pathetic, absolutely stupid and wholly terrible being exists. (By S5)
6. Therefore, YOU EXIST!! !
(on a side note, I wonder if this proof could be made to work)
