"Hark ye yet again— the little lower layer. All visible objects, man, are but as pasteboard masks. But in each event— in the living act, the undoubted deed— there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask! How can the prisoner reach outside except by thrusting through the wall?"
~ Herman Melville, Moby Dick
