I believe in the discipline of silence, and could talk for hours about it.

There comes a time when silence is betrayal.

It is never my custom to use words lightly. If twenty-seven years in prison have done anything to us, it was to use the silence of solitude to make us understand how precious words are and how real speech is in its impact on the way people live and die.

Nothing strengthens authority so much as silence.

In the end, we will remember not the words of our enemies, but the silence of our friends.

The most beautiful words of love are told in silence for a look.
