Silence: Lectures and Writings by John Cage
"There is no such thing as an empty space or an empty time. There is always something to see, something to hear. In fact, try as we may to make a silence, we cannot. Sounds occur whether intended or not; the psychological turning in direction of those not intended seems at first to be a giving up of everything that belongs to humanity. But one must see that humanity and nature, not separate, are in this world together, that nothing was lost when everything was given away."”
