“I dared, for the first and last time in my life, to express a theological conclusion: "But how can a necessary being exist totally polluted with the possible? What difference is there, then, between God and primogenial chaos? Isn't affirming God's absolute omnipotence and His absolute freedom with regard to His own choices tantamount to demonstrating that God does not exist?”

“And in that moment I experience a revelation.I realize now that it was a painful sense that the world is purposeless, the lazy fruit of a misunderstanding, but in that moment I was able to translate what I felt only as: "God does not exist.”

“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.”

“Nothing can shake my belief that this world is the fruit of a dark god whose shadow I extend.”

“When men stop believing in God, it isn't that they then believe in nothing: they believe in everything.”

“And when someone suggests you believe in a proposition, you must first examine it to see whether it is acceptable, because our reason was created by God, and whatever pleases our reason can but please divine reason, of which, for that matter, we know only what we infer from the processes of our own reason by analogy and often by negation.”

“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).”
