Shakespeare:
As You Like It
Act
V, Scene IV
 
Touchstone:         Faith, we met, and found the quarrel
was upon the seventh cause.
...
Jaques:                   But, for the seventh cause;
how did you find the quarrel on the seventh cause?
 
Touchstone:         Upon a lie seven times removed: thus,
sir. I did dislike the cut of a certain courtier's beard: he sent me word, 
 
if I said his beard was not cut well, he was in mind
it was: this is called Retort Courteous.
 
If I sent him word again 'it was not well cut,' he
would send me word, he cut it to please himself: this is called Quip Modest.
 
If again 'it was not well cut,' he disabled my
judgement: this is called Reply Churlish.
 
If again 'it was not well cut,' he would answer, I
spake not true: this is called Reproof Valiant.
 
If again 'it was not well cut,' he would say, I
lied: this is called Counter-check Quarrelsome;
 
and so to the Lie Circumstantial
 
and the Lie Direct.
 
Jaques:                   And how oft did you say his
beard was not well cut?
 
Touchstone:         I durst go no further than the Lie
Circumstantial, nor he durst not give me the Lie Direct; and so we measured
swords and parted.
 
Jaques:                   Can you nominate in order now
the degrees of the lie?
 
Touchstone:         O sir, we quarrel in print, by the
book; as you have books for good manners: I will name you the degrees.
The first, the Retort
Courteous;
the second, the Quip Modest;
the third, the Reply
Churlish;
the fourth, the Reproof
Valiant;
the fifth, the Counter-check
Quarrelsome;
the sixth, the Lie
Circumstantial;
the seventh, the Lie Direct.
All these you may avoid but the Lie Direct; and you
may avoid that too, with an If.
I knew when the seven justices could not take up a
quarrel, but when the parties were met themselves, one of them thought but of
an If as, 
'If you said so, then I said so.'
and they shook hands and swore brothers. 
Your If is the only peacemaker; much virtue in If.
 
Jaques:                   Is not this a rare fellow, my
lord? he's as good as any thing and yet a fool.
