The Ontological Argument for the Existence of God

[KevinM1]

Can anyone explain, in layman's terms, what the modal logic/reasoning thing actually is?

I have a suspicion that my general feelings about philosophy largely being masturbatory gobbledygook will remain in place regardless.

In context..... it's an axiomatic system which states that we can determine actuality by reference to possibility alone.  That's it, that's all, there's nothing more to it.

Sounds like BS. I see, from the link, that they have quasi-mathematical proof for it, but it still doesn't make sense to me that something does exist just because it's possible.
