For some reason this thread reminded me of the time my uncle, who never had any post-secondary education, came to visit me at college. He asked what classes I was taking and one of them was Philosophy 101. He said, "I never studied philosophy, but I invented my own. It goes like this:
I know what I know and I like what I like, and if you don't know it or like it, go **** yourself!"
Oh, and infinity definitely goes both ways!
