Philosophy finds talkativeness a disease very difficult and hard to cure. For its remedy, conversation, requires hearers: but talkative people hear nobody, for they are ever prating. And the first evil this inability to keep silence produces is an inability to listen.
PlutarchGood fortune will elevate even petty minds, and give them the appearance of a certain greatness and stateliness, as from their high place they look down upon the world; but the truly noble and resolved spirit raises itself, and becomes more conspicuous in times of disaster and ill fortune.
PlutarchIf any man think it a small matter, or of mean concernment, to bridle his tongue, he is much mistaken; for it is a point to be silent when occasion requires, and better than to speak, though never so well.
