A Quote by William Shakespeare on circumstances, direction, lies, modesty, order, peace, and virtue

Can you nominate in order now the degrees of the lie? 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 Countercheck 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. . . . Your If is the only peace-maker; much virtue in If.
