Aristotle, Nicomachean Ethics
H. Rackham, Ed.

Those then who go to excess in ridicule are thought to be buffoons and vulgar fellows, who itch to have their joke at all costs, and are more concerned to raise a laugh than to keep within the bounds of decorum and avoid giving pain to the object of their raillery. Those on the other hand who never by any chance say anything funny themselves and take offence at those who do, are considered boorish and morose. Those who jest with good taste are called witty¹ or versatile—that is to say, full of good turns; for such sallies seem to spring from the character, and we judge men's characters, like their bodies, by their movements.
