Be silent always when you doubt your sense.

“Do not too hastily conclude that silence is indifference. Indifference is not to care, not to act, not even to think or breathe. Indifference is inhuman and inhumane. Silence, on the other hand, is almost always premeditated, a willful act. Without silence there would be no sound.”

Heard melodies are sweet, but those unheard Are sweeter: therefore, ye soft pipes, play on

"If you do not understand my Silence, how will you understand my Words."

In human intercourse the tragedy begins, not when there is misunderstanding about words, but when silence is not understood.

It was after I got to Boston that I went into the anechoic chamber at Harvard University. Anybody who knows me knows this story. I am constantly telling it.

I did. He said, 'The high one was your nervous system in operation. The low one was your blood in circulation.'
