"put all of your superstitions out the window."

Put all your mind-closing b.s. out the window, we haven't discovered everything about the human mind yet, and our mind deals with perception of the world, how can we even hope to understand the external world when we can't even understand entirely the internal world of our own bodies? Anyone who tries to shut down someone's mind by closing out possibilities, by placing artificial limitations on perception, is a moron.
