Laserowitz, taking the “sections of silence” on the tapes for signals, was without question raving. And yet it was conceivable that at the same time the man could be right, seeing in the tapes a “communication”—if that communication was the very noise! An insane idea, but Rappaport could not rid himself of it. A stream of information—human speech, for example—does not always tell us that it is information and not a chaos of sounds.
