I concur Al I'm more so interested in the perceive notion of the subject not so much if it exist or not because everyone is different. What I perceive to exist may not be the same for you and your perception may be different from others, so I guess it all depends on each person's experiences. To me it's kinda like reading a book my creation of the world, characters and scenes that are talked about in the book would be completely different from somebody else's perception even the writer's and at the same time might actually be quite similar. But since it was a thought and therefore invented into reality therefore it lives which in my opinion just "is". The point is that we are both reading the same book what I get out of it is what I learned/experience from living or in this case reading it.
