Silence

It is a great misfortune not to possess sufficient wit to speak well, nor sufficient judgment to keep silent

The poets have been mysteriously silent on the subject of cheese

Certainty is the mother of quiet and repose, and uncertainty the cause of variance and contentions

It is no little wisdom for you to keep yourself in silence and in good peace when evil words are spoken to you, and to turn your heart to God and not to be troubled with the judgment of others
