The Ontological Argument - valid or debunked?

[GrandizerII]

It's just that in one system of logic, which you are certainly free to reject but it means you have to consistently reject it, possible existence is existence in a possible world (it's actual in the sense that it's true in that kind of world).

Possible existence is just existence that is possible. Actual existence in a possible world isn't merely existence that is possible. To conflate the two is a mistake.

What do you mean when you say that something actually exists in a possible world? Just so we're on the same page.

Because in that system of logic, existing in some possible world is the equivalent of possibly existing.
