Assuming those two things ever met head on.
My point was related to something (God) on a conceptual level. I don't believe it's necessary to have the strongest force in the universe meet the most adamantine object in order to see whether an unstoppable force or an immovable object exists.
It's possible that neither exists. If Superman is the strongest force, but can't move Kryptonite, while Wonder Woman can move Kryptonite, then neither would exist.
To completely prove that one or the other existed would, I believe, require that the force encounter every 'stable' object in the universe. This would take an infinite amount of time, so it's not possible to prove in one person's lifetime. The converse would be true to test the object against all forces.
I was stating that the concept of either one actually existing precludes the existence of the other. To me, that proves that it is possible to conceptualize something that doesn't exist. Thus, the fact that something can be conceptualized cannot logically be used as part of a proof that something exists.
And I'm not saying that was done in Anselm's 'proof'. I'm just pointing out that the argument 'I can conceive of something, so it must exist' is faulty.
But I do believe in Descartes' cogito, BKB. But that's something different.
