Metaphysical Stupidity
The act of smuggling a conclusion into a metaphysical premise, then acting as though logic has discovered something new. Common symptoms include excessive references to necessity, possible worlds, transcendental conditions, and speaking faster than the audience can ask where the conclusion came from.
Philosopher Bro: "A maximally great being necessarily exists in all possible worlds. If it's possible that such a being exists, then it exists necessarily. Therefore God exists."
Normal Person: "Hold on. Why is a necessarily existing God possible?"
Philosopher Bro: "Because a maximally great being necessarily exists in all possible worlds."
Normal Person: If it is logically possible that your conclusion was smuggled into your premise, then there exists a possible world in which your argument is metaphysically stupid. Since metaphysical stupidity, by definition, tracks premise-conclusion identity across possible worlds, it follows that your argument is necessarily metaphysically stupid, and thus Metaphysical Stupidity necessarily exists.
