Wit

There is this difference between wit and humor: 

wit makes you think, humor makes you laugh.

-Josh Billings

Wit has truth in it;

wisecracking is simply
calisthenics with words.
-Dorothy Parker

Wit surprises,
humor illuminates.
-Eli Schleifer

Wit penetrates; humor envelops. 

Wit is a function of verbal intelligence; 

humor is imagination operating on good nature.

-Peggy Noonan

Wit and Humor - if any difference it is in duration - lightning and electric light. 

Same material, apparently; but one is vivid, brief, and can do damage -

the other fools along and enjoys the elaboration.

-Mark Twain

The greatest fault of penetrating wit

is to go beyond its mark.

-Francois de la Rochefoucauld

Wit is far more a shield than a lance.

-Anonymous

Wit is the salt of conversation, not the food.
-William Hazlitt

Brevity is the soul of wit.
-William Shakespeare

True wit never makes us laugh.
-Ralph Waldo Emerson

Wit is, in fact, the eloquence of indifference.
-William Hazlitt
