"Intellectuals at work are very strange to look at. As strange as artists. I never could understand how an audience can sit there and look at a fiddler rolling his eyes and biting his tongue, or a horn player collecting spit, or a pianist like a black cat strapped to an electrified bench, as if what they saw had anything to do with the music." -- narrator of "The New Atlantis" by Ursula K. Le Guin, 1975
