“The belief that time is a linear, directed sequence running from A to B is a modern illusion. In fact, it can also go from B to A, the effect producing the cause.”

“I will tell you the deeper significance of this, which otherwise might seem a banal hydraulic joke. Caus knew that if one fills a vessel with water and seals it at the top, the water, even if one then opens a hole in the bottom, will not come out. But if one opens a hole in the top, also, the water spurts out below." "Isn't that obvious?" I said. "Air enters at the top and presses the water down." "A typical scientific explanation, in which the cause is mistaken for the effect, or vice versa. The question is not why the water comes out in the second place, but why it refuses to come out in the first case." "And why does it refuse?" Garamond asked eagerly. "Because, if it came out, it would leave a vacuum in the vessel, and nature abhors a vacuum. Nequaquam vacui was a Rosicrucian principle, which modern science has forgotten." "Excuse me," Belbo said to Agliè, "but your argument is simply post hoc ergo ante hoc. What follows causes what came before.You must not think linearly. The water in these fountains doesn't. Nature doesn't; nature knows nothing of time. Time is an invention of the West.”

“[...] there is one inexorable law of technology, and it is this: when revolutionary inventions become widely accessible, they cease to be accessible. Technology is inherently democratic, because it promises the same services to all; but it works only if the rich are alone using it. When the poor also adopt technology, it stops working. A train used to take two hours to go from A to B; then the motor car arrived, which could cover the same distance in one hour. For this reason cars were very expensive. But as soon as the masses could afford to buy them, the roads became jammed, and the trains started to move faster. Consider how absurd it is for the authorities constantly to urge people to use public transport, in the age of the automobile; but with public transport, by consenting not to belong to the elite, you get where you're going before members of the elite do.”

“Under torture you are as if under the dominion of those grasses that produce visions. Everything you have heard told, everything you have read returns to your mind, as if you were being transported, not toward heaven, but toward hell. Under torture you say not only what the inquisitor wants, but also what you imagine might please him, because a bond (this, truly, diabolical) is established between you and him ... These things I know, Ubertino; I also have belonged to those groups of men who believe they can produce the truth with white-hot iron. Well, let me tell you, the white heat of truth comes from another flame.”

“but I had also learned that freedom of speech means freedom from rhetoric.”

“There are magic moments, involving great physical fatigue and intense motor excitement, that produce visions of people known in the past ("en me retraçant ces détails, j'en suis à me demander s'ils sont réels, ou bien si je les ai rêvés"). As I learned later from the delightful little book of the Abbé de Bucquoy, there are also visions of books as yet unwritten.”

“The monkish vows keep us far from that sink of vice that is the female body, but often they bring us close to other errors. Can I finally hide from myself the fact that even today my old age is still stirred by the noonday demon when my eyes, in choir, happen to linger on the beardless face of a novice, pure and fresh as a maiden's?”
