"Senor Commander: I do not blame your disgust: a picture gallery is a dull place for a blind man. But even as you enjoy the contemplation of such romantic mirages as beauty and pleasure; so would I enjoy the contemplation of that which interests me above all things namely, Life: the force that ever strives to attain greater power of contemplating itself. What made this brain of mine, do you think? Not the need to move my limbs; for a rat with half my brains moves as well as I. Not merely the need to do, but the need to know what I do, lest in my blind efforts to live I should be slaying myself."
