"Silence is golden"

"An inability to stay quiet is one of the most conspicuous failings of mankind."
"Silence is a source of great strength."
"God's poet is silence! His song is unspoken,
And yet so profound, so loud, and so far,
It fills you, it thrills you with measures unbroken,
And as soft, and as fair, and as far as a star."
"Silence is a fence around wisdom."
"You hesitate to stab me with a word, and know not - silence is the sharper sword."
"To silence another, first be silent yourself."
"Silence was never written down."
