Sometimes when a father has an ugly, loutish son, the love he bears him so blindfolds his eyes that he does not see his defects, or, rather, takes them for gifts and charms of mind and body, and talks of them to his friends as wit and grace. I, however—for though I pass for the father, I am but the stepfather to "Don Quixote"—have no desire to go with the current of custom, or to implore thee, dearest reader, almost with tears in my eyes, as others do, to pardon or excuse the defects thou wilt perceive in this child of mine. Thou art neither its kinsman nor its friend, thy soul is thine own and thy will as free as any man's, whate'er he be, thou art in thine own house and master of it as much as the king of his taxes and thou knowest the common saying, "Under my cloak I kill the king;" all which exempts and frees thee from every consideration and obligation, and thou canst say what thou wilt of the story without fear of being abused for any ill or rewarded for any good thou mayest say of it.
In any case, Cide Hamete Benengeli was a very careful historian, and very accurate in all things, as can be clearly seen in the details he relates to us, for although they are trivial and inconsequential, he does not attempt to pass over them in silence; his example could be followed by solemn historians who recount actions so briefly and succinctly that we can barely taste them, and leave behind in the inkwell, through carelessness, malice, or ignorance, the most substantive part of the work.
If one were to reply that those who compose these books write them as fictions, and therefore are not obliged to consider the fine points of truth, I should respond that the more truthful the fiction, the better it is, and the more probable and possible, the more pleasing. Fictional tales must engage the minds of those who read them, and by restraining exaggeration and moderating impossibility, they enthrall the spirit and thereby astonish, captivate, delight, and entertain, allowing wonder and joy to move together at the same pace; none of these things can be accomplished by fleeing verisimilitude and mimesis, which together constitute perfection in writing.
Don't you be worried or annoyed, Sancho, about any comments you hear, or there will never be an end to them. Keep a safe conscience and let people say what they like: trying to still gossips' tongues is like putting up doors in open fields. If the governor leaves office rich they say he's a thief, and if he leaves it poor they say he's a milksop and a fool.
