TOUCHSTONE

                              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 the
mind it was: this is called the 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 the Quip Modest. If again 'it was
not well cut,' he disabled my judgment: this is
called the Reply Churlish. If again 'it was not
well cut,' he would answer, I spake not true: this
is called the Reproof Valiant. If again 'it was not
well cut,' he would say I lied: this is called the
Counter-cheque 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
Countercheque Quarrelsome; the sixth, the Lie with
Circumstance; 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 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.
