“As regards your government of yourself and your household, Sancho, my first piece of advice is to be clean and to cut your fingernails, and not to let them grow long, as some people do, moved by ignorance to believe that long nails make their hand look beautiful, as if those appendages, those excrescences that they leave uncut have any right to be called fingernails at all, because they are more like talons of a kestrel: a monstrous and filthy abuse.”

“Take my advice and live for a long, long time. Because the maddest thing a man can do in this life is to let himself die.”

“Sancho, just as you want people to believe what you have seen in the sky, I want you to believe what I saw in the Cave of Montesinos. And that is all I have to say.”

“I am not in the habit', said Don Quixote, 'of despoiling those whom I vanquish, nor is it a custom of chivalry to take their horses and leave them on foot, unless the victor has lost his own horse in the fray, in which case it is legitimate to take the defeated knight's horse, as a prize won in lawful war. And so, Sancho, leave that horse, or donkey, or whatever you want to call it, for as soon as its master sees that we have gone he will return for it.'God knows I'd love to take it', replied Sancho, 'or at least swap it for mine, because I don't think mine's such a good one. These laws of chivalry are really strict, if they won't even stretch to letting you swap one donkey for another - could you please tell me if I can at least swap the tackle?'I am not very clear about that', replied Don Quixote, 'and as it is a doubtful case, I should say that until I am better informed you can swap it, if your need is very great.'It's so great', said Sancho, 'that if I'd wanted the tackle to wear it myself I couldn't have needed it more.'And, now that he'd been granted official permission, he performed his mutatio capparum and refurbished his donkey.”

“Let's turn now to the citation of authors, found in other books and missing in yours. The solution to this is very simple, because all you have to do is find a book that cites them all from A to Z, as you put it. Then you'll put that same alphabet in your book, and though the lie is obvious it doesn't matter, since you'll have little need to use them; perhaps someone will be naive enough to believe you have consulted all of them in your plain and simple history; if it serves no other purpose, at least a lengthy catalogue of authors will give the book an unexpected authority. Furthermore, no one will try to determine if you followed them or did not follow them, having nothing to gain from that.”

“All the vices, Sancho, bring some kind of pleasure with them; but envy brings nothing but irritation, bitterness, and rage.”

“At this the duchess, laughing all the while, said: "Sancho Panza is right in all he has said, and will be right in all he shall say...”
