“...a book is a fragile creature, it suffers the wear of time, it fears rodents, the elements, clumsy hands. If for a hundred and a hundred years everyone had been able freely to handle our codices, the majority of them would no longer exist. So the librarian protects them not only against mankind but also against nature, and devotes his life to this war with the forces of oblivion, the enemy of truth.”

“Fear prophets, Adso, and those prepared to die for the truth, for as a rule they make many others die with them, often before them, at times instead of them.”

“In that face, deformed by hatred of philosophy, I saw for the first time the portrait of the Antichrist, who does not come from the tribe of Judas, as his heralds have it, or from a far country. The Antichrist can be born from piety itself, from excessive love of God or of the truth, as the heretic is born from the saint and the possessed from the seer. Fear prophets, Adso, and those prepared to die for the truth, for as a rule they make many others die with them, often before them, at times instead of them. Jorge did a diabolical thing because he loved his truth so lewdly that he dared anything in order to destroy falsehood.”

“William was deeply humiliated. I tried to comfort him; I told him that for three days he had been looking for a text in Greek and it was natural in the course of his examination for him to discard all books not in Greek. And he answered that it is certainly human to make mistakes, but there are some human beings who make more than others, and they are called fools, and he was one of them, and he wondered whether it was worth the effort to study in Paris and Oxford if one was then incapable of thinking that manuscripts are also bound in groups, a fact even novices know, except stupid ones like me, and a pair of clowns like the two of us would be a great success at fairs, and that was what we should do instead of trying to solve mysteries, especially when we were up against people far more clever than we.”

“It is necessary to create constraints, in order to invent freely. In poetry the constraint can be imposed by meter, foot, rhyme, by what has been called the "verse according to the ear."... In fiction, the surrounding world provides the constraint. This has nothing to do with realism... A completely unreal world can be constructed, in which asses fly and princesses are restored to life by a kiss; but that world, purely possible and unrealistic, must exist according to structures defined at the outset (we have to know whether it is a world where a princess can be restored to life only by the kiss of a prince, or also by that of a witch, and whether the princess's kiss transforms only frogs into princes or also, for example, armadillos).”

“I was dozing, and the clock woke me. I didn’t hear the first few chimes distinctly, that is to say, I didn’t count them. But as soon as I decided to count I realized that there had already been three, so I was able to count four, five, and so on. I understood that I could say four and then wait for the fifth, because one, two, and three had passed, and I somehow knew that. If the fourth chime had been the first I was conscious of, I would have thought it was six o’clock. I think our lives are like that—you can only anticipate the future if you can call the past to mind. I can’t count the chimes of my life because I don’t know how many came before. On the other hand, I dozed off because the chair had been rocking for a while. And I dozed off in a certain moment because that moment had been preceded by other moments, and because I was relaxing while awaiting the subsequent moment. But if the first moments hadn’t put me in the right frame of mind, if I had begun rocking in any old moment, I wouldn’t have expected what had to come. I would have remained awake. You need memory even to fall asleep. Or no?”
