Silence a boundary notion, a conceptual ideal, an aural vanishing point. Saying something about silence equals loosing it. Being silent is impossible may it include to cease living. Many words have been uttered to grasp this paradox.
There is no such thing as silence. Something is always happening that makes a sound.
No Silence exists, that is not pregnant with sound.
Until I die there will be sounds. And they will continue following my death. - John Cage
