Silence is Wisdom where Speaking is Folly.
Words are the money of fools.
It is ill-manners to silence a fool and cruelty to let him go on
The wise hand doth not all that the foolish mouth speakes. [The wise hand doth not all that the foolish mouth speaks.]
There is no slander in an allowed fool, though he do nothing but rail.
As empty vessels make the loudest sound, so they that have the least wit are the greatest blabbers
A fool's wild speech confounds the wise.
My belief in free speech is so profound that I am seldom tempted to deny it to the other fellow. Nor do I make any effort to differentiate between the other fellow right and that other fellow wrong, for I am convinced that free speech is worth nothing unless it includes a full franchise to be foolish and even...malicious.
Idiot wind, blowing every time you open your mouth.
Where there is a great deal of free speech there is always a certain amount of foolish speech.
Does a man speak foolishly?--suffer him gladly, for you are wise. Does he speak erroneously?--stop such a man's mouth with sound words that cannot be gainsaid. Does he speak truly?--rejoice in the truth.
A doctor who doesn't say too many foolish things is a patient half-cured.
A fool and his words are soon parted.
The heart of a fool is in his mouth, but the mouth of a wise man is in his heart.
A kind Of excellent dumb discourse.
It is not, then, in the content or substance of folly that its difference from truth lies, but in where it comes from. It comes not from 'the wise man's mouth' but from the mouth of the subject assumed not to know and speak the truth.
