Be silent, or say something better than silence.
Proper words in proper places make the true definition of a style.
It is as easy to draw back a stone, thrown with force from the hand, as to recall a word once spoken.
Much tongue and much judgment seldom go together.
If the truth were self evident, eloquence would be unnecessary.
We never listen when we are eager to speak.
François de La Rochefoucauld
He that converses not, knows nothing.
It is good to rub and polish our brain
against that of others.
My words fly up, my thoughts remain below: Words without thoughts, never to heaven go.
William Shakespeare, Hamlet. Act III. Sc. 3
Kind words are the music of the world.
F. W. Faber
People who have nothing to say are never at a loss in talking.
Deliver your words not by number but by weight.
The great thing is to know when to speak and when to keep quiet.
Seneca the Younger
Silence is often advantageous.
Many can argue - not many converse.
A. Bronson Alcott
The less people speak of their greatness,
the more we think of it.
Sir Francis Bacon
Language is the close-fitting dress of Thought.
R. C. Trench
Good, the more communicated, more abundant grows.
The first ingredient in conversation is truth:
the next good sense; the third, good humor;
and the fourth wit.
Sir William Temple
True eloquence, indeed, does not consist in speech. It cannot be brought from far. Labor and learning may toil for it, but they will toil in vain. Words and phrases may be marshalled in every way, but they cannot compass it. It must exist in the man, in the subject, and in the occasion.
