Silence

John Cage's famed piece is just that 4'33 (of silence). "The rest is silence" says Hamlet. "Whereof one cannot speak, there of one must be silent." Take God. Here the inability to speak doesn't  imply andence. Silence is hyperbole in fact. The fact that that you can't speak about something means there's too much to be said. It's like talking with your mouth full. There are two situations in which silence is a particularly effective tool. Thd first is in a potential argument. By not weighing in, you are able to hear the other (a powerful weapon in itself) and most importantly one's as yet unexpressed thoughts. The second is less passive. Silent is an advocate. Most people don't like being moved from their inertial state but silence has the power of negative energy, which magnetically draws its object in.
