“But why do some people support [the heretics]?" "Because it serves their purposes, which concern the faith rarely, and more often the conquest of power." "Is that why the church of Rome accuses all its adversaries of heresy?" "That is why, and that is also why it recognizes as orthodoxy any heresy it can bring back under its own control or must accept because the heresy has become too strong.”

“The faith a movement proclaims doesn't count: what counts is the hope it offers. All heresies are the banner of a reality, an exclusion. Scratch the heresy and you will find the leper. Every battle against heresy wants only this: to keep the leper as he is.”

“Then why do you want to know?""Because learning does not consist only of knowing what we must or we can do, but also of knowing what we could do and perhaps should not do.”

“But can I really will anything? At this moment I feel the pleasure of being stone, the sun warms me, the wind makes acceptable this adjustment of my body, I have no intention of ceasing to be a stone. Why? Because I like it. So then I too am slave to a passion, which advises me against wanting freely its opposite. However, willing, I could will. And yet I do not. How much freer am I than a stone?”

“The older I grow and the more I abandon myself to God's will, the lessI value intelligence that wants to know and will that wants to do; andas the only element of salvation I recognize faith, which can wait patiently, without asking too many questions.”

“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.”

“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.”
