William Congreve 
The Way of the World [EPUB ebook] 

My Lord, —Whether the world will arraign me of vanity or not, that I have presumed to dedicate this comedy to your lordship, I am yet in doubt; though, it may be, it is some degree of vanity even to doubt of it. One who has at any time had the honour of your lordship’s conversation, cannot be supposed to think very meanly of that which he would prefer to your perusal. Yet it were to incur the imputation of too much sufficiency to pretend to such a merit as might abide the test of your lordship’s censure.
Whatever value may be wanting to this play while yet it is mine, will be sufficiently made up to it when it is once become your lordship’s; and it is my security, that I cannot have overrated it more by my dedication than your lordship will dignify it by your patronage.
That it succeeded on the stage was almost beyond my expectation; for but little of it was prepared for that general taste which seems now to be predominant in the palates of our audience.
Those characters which are meant to be ridiculed in most of our comedies are of fools so gross, that in my humble opinion they should rather disturb than divert the well-natured and reflecting part of an audience; they are rather objects of charity than contempt, and instead of moving our mirth, they ought very often to excite our compassion.
