“[But the man who comes back through the Door in the Wall will never be quite the same as the man who went out.] He will be wiser but less cocksure, happier but less self-satisfied, humbler in acknowledging his ignorance yet better equipped to understand the relationship of words to things, of systematic reasoning to the unfathomable Mystery which it tries, forever vainly, to comprehend.”

~ Aldous Huxley, from The Doors of Perception
