I remember Keats and the whole truth is beauty, beauty truth thing. I feel like it's actually, truth is ugly, always. I mean, have you ever found out the truth and not been disappointed?
Douglas Adams said it better than I can: "I'd take the awe of understanding over the awe of ignorance any day."
Why? If I had to guess, I would say you are uncomfortable with intrinsic uncertainty. Or is it something else?
