“Because the universe was full of ignorance all around and the scientist panned through it like a prospector crouched over a mountain stream, looking for the gold of knowledge among the gravel of unreason, the sand of uncertainty and the little whiskery eight-legged swimming things of superstition.”

“Imagine a land where people are afraid of dragons. It is a reasonable fear: dragons possess a number of qualities that make being afraid of them a very commendable response. Things like their terrible size, their ability to spout fire, or to crack boulders into splinters with their massive talons. In fact, the only terrifying quality that dragons do not possess is that of existence.Now, the people of this land know about dragons because their leaders have warned them about them. They tell stories about cruel dragons with razor teeth and fiery breath. They recount legends of dragons hunting by night on silent wings. In short, the leaders make sure that the people believe in all the qualities of dragons, including that key quality of existence. And then they control the people — when they need to — with their fear of dragons. The people pay a dragon-slaying tax … everyone stays indoors after dark to avoid being snatched by swooping claws … and nobody ever strays out of bounds for fear of being eaten well and truly up.Perhaps somebody will wonder if dragons aren’t, after all, fictitious because — despite their size — nobody seems to have actually seen one. And so it is necessary from time to time to provide evidence: a burnt tree or two, a splintered rock, the mysterious absence of a villager. The population is controlled by the dragons in its collective mind. It’s contrived superstition, and it is possible because the people do not know enough about the way the world works to know that dragons do not exist.”

“My theory is that hope is a form of madness. A benevolent one, sure, but madness all the same. Like an irrational superstition–broken mirrors and so forth–hope’s not based on any kind of logic, it’s just unfettered optimism, grounded in nothing but faith in things beyond our control.”

“When even the brightest mind in our world has been trained up from childhood in a superstition of any kind, it will never be possible for that mind, in its maturity, to examine sincerely, dispassionately, and conscientiously any evidence or any circumstance which shall seem to cast a doubt upon the validity of that superstition. I doubt if I could do it myself.”

“Four times during the first six days they were assembled and briefed and then sent back. Once, they took off and were flying in formation when the control tower summoned them down. The more it rained, the worse they suffered. The worse they suffered, the more they prayed that it would continue raining. All through the night, men looked at the sky and were saddened by the stars. All through the day, they looked at the bomb line on the big, wobbling easel map of Italy that blew over in the wind and was dragged in under the awning of the intelligence tent every time the rain began. The bomb line was a scarlet band of narrow satin ribbon that delineated the forward most position of the Allied ground forces in every sector of the Italian mainland.For hours they stared relentlessly at the scarlet ribbon on the map and hated it because it would not move up high enough to encompass the city.When night fell, they congregated in the darkness with flashlights, continuing their macabre vigil at the bomb line in brooding entreaty as though hoping to move the ribbon up by the collective weight of their sullen prayers. “I really can’t believe it,” Clevinger exclaimed to Yossarian in a voice rising and falling in protest and wonder. “It’s a complete reversion to primitive superstition. They’re confusing cause and effect. It makes as much sense as knocking on wood or crossing your fingers. They really believe that we wouldn’t have to fly that mission tomorrow if someone would only tiptoe up to the map in the middle of the night and move the bomb line over Bologna. Can you imagine? You and I must be the only rational ones left.”In the middle of the night Yossarian knocked on wood, crossed his fingers, and tiptoed out of his tent to move the bomb line up over Bologna.”

“Mathematical Knowledge adds a manly Vigour to the Mind, frees it from Prejudice, Credulity, and Superstition.”

“I remember being scared that something must, surely, go wrong, if we were this happy, her and me, in the early days, when our love was settling into the shape of our lives like cake mixture reaching the corners of the tin as it swells and bakes.”

“I leave pansies, the symbolic flower of freethought, in memory of the Great Agnostic, Robert Ingersoll, who stood for equality, education, progress, free ideas and free lives, against the superstition and bigotry of religious dogma. We need men like him today more than ever. His writing still inspires us and challenges the ‘better angels’ of our nature, when people open their hearts and minds to his simple, honest humanity. Thank goodness he was here.”

“You never see animals going through the absurd and often horrible fooleries of magic and religion. . . . Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, quite intelligent enough.”

“Politics: the art of using euphemisms, lies, emotionalism and fear-mongering to dupe average people into accepting–or even demanding–their own enslavement.”

“People think that epilepsy is divine simply because they don’t have any idea what causes epilepsy. But I believe that someday we will understand what causes epilepsy, and at that moment, we will cease to believe that it’s divine. And so it is with everything in the universe”

“I do not pretend to be able to prove that there is no God. I equally cannot prove that Satan is a fiction. The Christian god may exist; so may the gods of Olympus, or of ancient Egypt, or of Babylon. But no one of these hypotheses is more probable than any other: they lie outside the region of even probable knowledge, and therefore there is no reason to consider any of them.”

“What is it you most dislike? Stupidity, especially in its nastiest forms of racism and superstition.”

“Give me the storm and tempest of thought and action, rather than the dead calm of ignorance and faith! Banish me from Eden when you will; but first let me eat of the fruit of the tree of knowledge!”

“May it [American independence] be to the world, what I believe it will be, (to some parts sooner, to others later, but finally to all,) the signal of arousing men to burst the chains under which monkish ignorance and superstition had persuaded them to bind themselves, and to assume the blessings and security of self-government. That form which we have substituted, restores the free right to the unbounded exercise of reason and freedom of opinion. All eyes are opened, or opening, to the rights of man. The general spread of the light of science has already laid open to every view the palpable truth, that the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them legitimately… These are grounds of hope for others. For ourselves, let the annual return of this day forever refresh our recollections of these rights, and an undiminished devotion to them.[Letter to Roger C. Weightman on the anniversary of the signing of the Declaration of Independence in 1776, 24 June 1826. This was Jefferson’s last letter]”
