“The ability to reason the un-reason which has afflicted by reason saps my ability to reason, so that I complain with good reason of your infinite loveliness.”

“The reason for the unreason with which you treat my reason , so weakens my reason that with reason I complain of your beauty.”

“Have I not already told you', replied Don Quixote, 'that I intend to imitate Amadis, and to act the desperate, foolish, furious lover so as also to imitate the valiant Orlando, when he found signs by a spring that the fair Angelica had disgraced herself with Medoro, and the grief turned him mad, and he uprooted trees, sullied the waters of clear springs, slew shepherds, destroyed flocks, burned cottages, tore down houses, dragged away mares and performed a hundred other excesses, worthy to be recorded on the tablets of eternal fame?' [...] 'But to my mind', said Sancho, 'the knights who did all that were pushed into it and had their reasons for their antics and their penances, but what reason have you got for going mad?' 'That is the whole point', replied Don Quixote, 'and therein lies the beauty of my enterprise. A Knight Errant going mad for a good reason - there is neither pleasure nor merit in that. The thing is to become insane without a cause and have my lady think: If I do all this when dry, what would I not do when wet?”

“...he spent whole days and nights over his books; and thus with little sleeping and much reading his brains dried up to such a degree that he lost the use of his reason.”

“If all, or almost all, the plays that are popular now, imaginative works as well as historical ones, are known to be nonsense and without rhyme or reason, and despite this the mob hears them with pleasure and thinks of them and approves of them as good, when they are very far from being so, and the authors who compose them and the actors who perform them say they must be like this because that is just how the mob wants them, and no other way; the plays that have a design and follow the story as art demands appeal to a handful of discerning persons who understand them, while everyone else is incapable of comprehending their artistry; and since, as far as the authors and actors are concerned, it is better to earn a living with the crowd than a reputation with the elite, this is what would happen to my book after I had singed my eyebrows trying to keep the precepts I have mentioned and had become the tailor who wasn't paid.”

“It is not the responsibility of knights errant to discover whether the afflicted, the enchained and the oppressed whom they encounter on the road are reduced to these circumstances and suffer this distress for their vices, or for their virtues: the knight's sole responsibility is to succour them as people in need, having eyes only for their sufferings, not for their misdeeds. I came across a rosary of angry, wretched men, I did with them what my religion requires of me, and nothing else is any concern of mine; and to anyone who thinks ill of it - saving, reverend sir, your holy dignity and honorable person - I say that he is no judge of matters of chivalry, and that he is lying like a bastard and a son of a whore, and I swear by my gospel-oath that I will make him acknowledge this with my sword, at length and in extenso.”

“To think that the affairs of this life always remain in the same state is a vain presumption; indeed they all seem to be perpetually changing and moving in a circular course. Spring is followed by summer, summer by autumn, and autumn by winter, which is again followed by spring, and so time continues its everlasting round. But the life of man is ever racing to its end, swifter than time itself, without hope of renewal, unless in the next that is limitless and infinite.”
