@The Pentacle Queen,
I love the ontological argument for the existence of god.
If you read it as is, it's not uncommon to get a major "It's valid!!!!" response (some really reputable philosophers have had this reaction for a moment...it wasn't just a pleb like me.)
Only...it's really hard to get it online without the crtique of its validity coming first/used as a basic assumption.
Best to read it in a philosophy book just stated.
This is the closest I could get:

The rebuttals/critiques are everywhere online...and doubtles sincluded in this site.
But...see if you can have a bit of fun with it WITHOUT reading the critiques first.
