The world is never quiet, even its silence eternally resounds with the same notes, in vibrations which escape our ears. As for those that we perceive, they carry sounds to us, occasionally a chord, never a melody.Albert Camus
Some animals utter a loud cry. Some are silent, and others have a voice, which in some cases may be expressed by a word; in others, it cannot. There are also noisy animals and silent animals, musical and unmusical kinds, but they are mostly noisy about the breeding season.Aristotle
Sometimes one creates a dynamic impression by saying something, and sometimes one creates as significant an impression by remaining silent.Dalai Lama
