Galileo Quotes

Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.

I have never met a man so ignorant that I couldn't learn something from him.

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.

You cannot teach a man anything, you can only help him find it within himself.

A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words, and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day. — 'Ah, so you shall be sure to be misunderstood.' — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

The aim of science is not to open the door to infinite wisdom, but to set a limit to infinite error.

All truths are easy to understand once they are discovered; the point is to discover them.

Passion is the genesis of genius.

Sometimes, all you had to do was exist in order to be someone's saviour.

The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

We owe a huge debt to Galileo for emancipating us all from the stupid belief in an Earth-centered or man-centered (let alone God-centered) system. He quite literally taught us our place and allowed us to go on to make extraordinary advances in knowledge.

It is a beautiful and delightful sight to behold the body of the Moon.

Unhappy the land that is in need of heroes

Wine is sunlight, held together by water.

There are those who reason well, but they are greatly outnumbered by those who reason badly.

Philosophy [nature] is written in that great book which ever is before our eyes -- I mean the universe -- but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. The book is written in mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders in vain through a dark labyrinth.

It’s more difficult to create the problem than to solve it. All the person trying to solve the problem has to do is always respect the problem’s creator.

Mathematics is the language in which God has written the universe

Copernicus, Galileo, and Kepler did not solve an old problem, they asked a new question, and in doing so they changed the whole basis on which the old questions had been framed.

Eppur si muove.

Measure what can be measured, and make measurable what cannot be measured.

Misunderstood! It is a right fool's word. Is it so bad then to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.

Was the majority right when they stood by while Jesus was crucified? Was the majority right when they refused to believe that the earth moved around the sun and let Galileo be driven to his knees like a dog? It takes fifty years for the majority to be right. The majority is never right until it does right.

The so-called Christian nations are the most enlightened and progressive ... but in spite of their religion, not because of it. The Church has opposed every innovation and discovery from the day of Galileo down to our own time, when the use of anesthetic in childbirth was regarded as a sin because it avoided the biblical curse pronounced against Eve. And every step in astronomy and geology ever taken has been opposed by bigotry and superstition. The Greeks surpassed us in artistic culture and in architecture five hundred years before Christian religion was born.

Sì perché l'autorità dell'opinione di mille nelle scienze non val per una scintilla di ragione di un solo, sì perché le presenti osservazioni spogliano d'autorità i decreti de' passati scrittori, i quali se vedute l'avessero, avrebbono diversamente determinato. For in the sciences the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man. Besides, the modern observations deprive all former writers of any authority, since if they had seen what we see, they would have judged as we judge.

Watching people is a bit of a hobby of mine. It's quite fascinating, really.

E pur si muove." (And yet it moves.) (What Galileo purportedly muttered after torturers forced him to recant his theory that the earth orbits the sun.)

My life had taken a stranger turn than I could've ever imagined. What was I doing on this path? Where was I headed really? Who was I to take on a battle between powers I didn't understand— armed with a runaway cat, a uniquely bad drummer, a pair of garden shears, and an Ovaltine-drinking teen Galileo? To save a girl who didn't want to be saved?

My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?

E pur si muove. (Albeit It does move.) [What Galileo purportedly muttered after torturers forced him to recant his theory that the earth orbits the sun.]

Nowadays, anyone who wishes to combat lies and ignorance and to write the truth must overcome at least five difficulties. He must have the courage to write the truth when truth is everywhere opposed; the keenness to recognize it, although it is everywhere concealed; the skill to manipulate it as a weapon; the judgment to select those in whose hands it will be effective; and the running to spread the truth among such persons.

Long experience has taught me this about the status of mankind with regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them, while on the other hand to know and understand a multitude of things renders men cautious in passing judgment upon anything new.

By denying scientific principles, one may maintain any paradox.

It is surely harmful to souls to make it a heresy to believe what is proved.

I would argue that masturbation is the human animal's most important adaptation. The very cornerstone of our technological civilization. Our hands evolved to grip tools, all right—including our own. You see, thinkers, inventors, and scientists are usually geeks, and geeks have a harder time getting laid than anyone. Without the built-in sexual release valve provided by masturbation, it's doubtful that early humans would have ever mastered the secrets of fire or discovered the wheel. And you can bet that Galileo, Newton, and Einstein never would have made their discoveries if they hadn't first been able to clear their heads by slapping the salami (or "knocking a few protons off the old hydrogen atom"). The same goes for Marie Curie. Before she discovered radium, you can be certain she first discovered the little man in the canoe.

Even when you’re at the top, there’s always something higher,

There are many perks to living for twenty-one centuries, and foremost among them is bearing witness to the rare birth of genius. It invariably goes like this: Someone shrugs off the weight of his cultural traditions, ignores the baleful stares of authority, and does something his countrymen think to be completely batshit insane. Of those, Galileo was my personal favorite. Van Gogh comes in second, but he really was batshit insane.

With regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them.

Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.

See now the power of truth; the same experiment which at first glance seemed to show one thing, when more carefully examined, assures us of the contrary.

I've loved the stars too fondly to be fearful of the night.

If Galileo had said in verse that the world moved, the inquisition might have let him alone.

The Bible shows the way to go to heaven, not the way the heavens go.

We cannot teach people anything; we can only help them discover it within themselves.

In the sciences, the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man.

Thinking is one of the greatest pleasures of the human race.

Such a lot is won when even a single man gets to his feet and says No

To stand by yourself -- that was also part of dignity. That way, a person could get through a public flaying with dignity. Galileo. Luther. Even somebody who admitted his guilt and resisted the temptation to deny it. Something politicians couldn't do. Honesty, the courage for honesty. With others and yourself.

They seemed to forget that the increase of known truths stimulates the investigation, establishment and growth of the arts; not their dimination or destruction.

Philosophy is written in that great book which ever lies before our eyes — I mean the universe — but we cannot understand it if we do not first learn the language and grasp the symbols, in which it is written

Galileo once wrote, "You cannot teach a man anything; you can only help him find it within himself.

Ah, so you shall be sure to be misunderstood." -Is it so bad, then to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood...

We all have secret lives. The life of excretion; the world of inappropriate sexual fantasies; our real hopes, our terror of death; our experience of shame; the world of pain; and our dreams. No one else knows these lives. Consciousness is solitary. Each person lives in that bubble universe that rests under the skull, alone.

Which is harder: devising an unsolvable problem, or solving that problem?

Measure what is measurable, and make measurable what is not so

Aristotle said a bunch of stuff that was wrong. Galileo and Newton fixed things up. Then Einstein broke everything again. Now, we’ve basically got it all worked out, except for small stuff, big stuff, hot stuff, cold stuff, fast stuff, heavy stuff, dark stuff, turbulence, and the concept of time

A man who doesn't know the truth is just an idiot, but a man who knows the truth and calls it a lie is a crook.

In the history of science, ever since the famous trial of Galileo, it has repeatedly been claimed that scientific truth cannot be reconciled with the religious interpretation of the world. Although I an now convinced that scientific truth is unassailable in its own field, I have never found it possible to dismiss the content of religious thinking as simply part of an outmoded phase in the consciousness of mankind, a part we shall have to give up from now on, Thus in the course of my life I have repeatedly been compelled to ponder on the relationship of these two regions of though, for I have never been able to doubt the reality of that to which they point.

So this is where all the vapid talk about the 'soul' of the universe is actually headed. Once the hard-won principles of reason and science have been discredited, the world will not pass into the hands of credulous herbivores who keep crystals by their sides and swoon over the poems of Khalil Gibran. The 'vacuum' will be invaded instead by determined fundamentalists of every stripe who already know the truth by means of revelation and who actually seek real and serious power in the here and now. One thinks of the painstaking, cloud-dispelling labor of British scientists from Isaac Newton to Joseph Priestley to Charles Darwin to Ernest Rutherford to Alan Turing and Francis Crick, much of it built upon the shoulders of Galileo and Copernicus, only to see it casually slandered by a moral and intellectual weakling from the usurping House of Hanover. An awful embarrassment awaits the British if they do not declare for a republic based on verifiable laws and principles, both political and scientific.

The sun, with all the planets revolving around it, and depending on it, can still ripen a bunch of grapes as though it had nothing else in the universe to do.

Personally, I always compare myself to Galileo because everyone knows he’s fantastic, but he has no spoons at all because he’s dead. So technically I’m better than Galileo because all I’ve done is take a shower and already I’ve accomplished more than him today.

I am not very impressed with theological arguments whatever they may be used to support. Such arguments have often been found unsatisfactory in the past. In the time of Galileo it was argued that the texts, 'And the sun stood still... and hasted not to go down about a whole day' (Joshua x. 13) and 'He laid the foundations of the earth, that it should not move at any time' (Psalm cv. 5) were an adequate refutation of the Copernican theory.

Sometimes it's as important to prove there is no answer to a question as it is to answer it.

That's what happens when you free people from the restraints of time. They make their own rigid schedule.

And, believe me, if I were again beginning my studies, I should follow the advice of Plato and start with mathematics.

Do you know about the spoons? Because you should. The Spoon Theory was created by a friend of mine, Christine Miserandino, to explain the limits you have when you live with chronic illness. Most healthy people have a seemingly infinite number of spoons at their disposal, each one representing the energy needed to do a task. You get up in the morning. That’s a spoon. You take a shower. That’s a spoon. You work, and play, and clean, and love, and hate, and that’s lots of damn spoons … but if you are young and healthy you still have spoons left over as you fall asleep and wait for the new supply of spoons to be delivered in the morning. But if you are sick or in pain, your exhaustion changes you and the number of spoons you have. Autoimmune disease or chronic pain like I have with my arthritis cuts down on your spoons. Depression or anxiety takes away even more. Maybe you only have six spoons to use that day. Sometimes you have even fewer. And you look at the things you need to do and realize that you don’t have enough spoons to do them all. If you clean the house you won’t have any spoons left to exercise. You can visit a friend but you won’t have enough spoons to drive yourself back home. You can accomplish everything a normal person does for hours but then you hit a wall and fall into bed thinking, “I wish I could stop breathing for an hour because it’s exhausting, all this inhaling and exhaling.” And then your husband sees you lying on the bed and raises his eyebrow seductively and you say, “No. I can’t have sex with you today because there aren’t enough spoons,” and he looks at you strangely because that sounds kinky, and not in a good way. And you know you should explain the Spoon Theory so he won’t get mad but you don’t have the energy to explain properly because you used your last spoon of the morning picking up his dry cleaning so instead you just defensively yell: “I SPENT ALL MY SPOONS ON YOUR LAUNDRY,” and he says, “What the … You can’t pay for dry cleaning with spoons. What is wrong with you?” Now you’re mad because this is his fault too but you’re too tired to fight out loud and so you have the argument in your mind, but it doesn’t go well because you’re too tired to defend yourself even in your head, and the critical internal voices take over and you’re too tired not to believe them. Then you get more depressed and the next day you wake up with even fewer spoons and so you try to make spoons out of caffeine and willpower but that never really works. The only thing that does work is realizing that your lack of spoons is not your fault, and to remind yourself of that fact over and over as you compare your fucked-up life to everyone else’s just-as-fucked-up-but-not-as-noticeably-to-outsiders lives. Really, the only people you should be comparing yourself to would be people who make you feel better by comparison. For instance, people who are in comas, because those people have no spoons at all and you don’t see anyone judging them. Personally, I always compare myself to Galileo because everyone knows he’s fantastic, but he has no spoons at all because he’s dead. So technically I’m better than Galileo because all I’ve done is take a shower and already I’ve accomplished more than him today. If we were having a competition I’d have beaten him in daily accomplishments every damn day of my life. But I’m not gloating because Galileo can’t control his current spoon supply any more than I can, and if Galileo couldn’t figure out how to keep his dwindling spoon supply I think it’s pretty unfair of me to judge myself for mine. I’ve learned to use my spoons wisely. To say no. To push myself, but not too hard. To try to enjoy the amazingness of life while teetering at the edge of terror and fatigue.

he presented me with a mathematical conundrum,” he said. “It’s a famous one, the P = NP problem. Basically, it asks whether it’s more difficult to think of the solution to a problem yourself or to ascertain if someone else’s answer to the same problem is correct.

Then I will tell you something. I do not believe in it. Forty years among men has consistently taught me that they are not amenable to common sense. Show them the red tail of a comet, fill them with black terror, and they will all come running out of their houses and break their legs. But tell them one sensible proposition and support it with seven reasons, and they will simply laugh in your face

I learned an important lesson: Never take the obvious for granted. Once upon a time, it was so obvious that a four-pound rock would plummet earthward twice as fast as a two-pound rock that no one ever bothered to test it. That is, until Galileo Galilei came along and took ten minutes to perform an elegantly simple experiment that yielded a counterintuitive result and changed the course of history.

(T)he increase of known truths stimulates the investigation, establishment, and growth of the arts.

Mathematics is the language with which God has written the universe.

His lack of reverence for authority and his willingness to challenge received wisdom would lead him to craft an empirical approach for understanding nature that foreshadowed the scientific method developed more than a century later by Bacon and Galileo. His method was rooted in experiment, curiosity, and the ability to marvel at phenomena that the rest of us rarely pause to ponder after we’ve outgrown our wonder years.

Who indeed will set bounds to human ingenuity? Who will assert that everything in the universe capable of being perceived is already discovered and known?

How am I supposed to know?” she asked instead. “What’s it supposed to be like?” Lana and Claire traded tiny smiles, and Claire asked gently, “What’s what supposed to be like?” Lily slumped back against the sofa, feeling boneless and muddled. “Falling in love, I guess.” “You’ll know,” Claire said. “It’s unmistakable.” (How she could recognize Kath at the other end of a crowded Galileo hallway by the way she walked.) “It’s like . . . well, it’s like falling,” Lana said. “Falling, or floating, or sinking.” (Every time they kissed.) “You won’t know which way is up.” “It’s like having a fever.” (The way the world seemed to narrow down to the tips of Kath’s fingers.) “It’s like being drunk—drunk for days.

I'm teaching all the time. When am I to learn?

It is a good principle in science not to believe any 'fact'---however well attested---until it fits into some accepted frame of reference. Occasionally, of course, an observation can shatter the frame and force the construction of a new one, but that is extremely rare. Galileos and Einsteins seldom appear more than once per century, which is just as well for the equanimity of mankind.

I esteem myself happy to have as great an ally as you in my search for truth. I will read your work ... all the more willingly because I have for many years been a partisan of the Copernican view because it reveals to me the causes of many natural phenomena that are entirely incomprehensible in the light of the generally accepted hypothesis. To refute the latter I have collected many proofs, but I do not publish them, because I am deterred by the fate of our teacher Copernicus who, although he had won immortal fame with a few, was ridiculed and condemned by countless people (for very great is the number of the stupid). {Letter to fellow revolutionary astronomer Johannes Kepelr}

In time you may discover everything that can be discovered, and still your progress will only be progress away from humanity. The distance between you and them can one day become so great that your joyous cry over some new gain could be answered by an universal shriek of horror.

I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments and demonstrations.

It is the fate of great achievements, born from a way of life that sets truth before security, to be gobbled up by you and excreted in the form of shit. For centuries great, brave, lonely men have been telling you what to do. Time and again you have corrupted, diminished and demolished their teachings; time and again you have been captivated by their weakest points, taken not the great truth, but some trifling error as your guiding principal. This, little man, is what you have done with Christianity, with the doctrine of sovereign people, with socialism, with everything you touch. Why, you ask, do you do this? I don't believe you really want an answer. When you hear the truth you'll cry bloody murder, or commit it. … You had your choice between soaring to superhuman heights with Nietzsche and sinking into subhuman depths with Hitler. You shouted Heil! Heil! and chose the subhuman. You had the choice between Lenin's truly democratic constitution and Stalin's dictatorship. You chose Stalin's dictatorship. You had your choice between Freud's elucidation of the sexual core of your psychic disorders and his theory of cultural adaptation. You dropped the theory of sexuality and chose his theory of cultural adaptation, which left you hanging in mid-air. You had your choice between Jesus and his majestic simplicity and Paul with his celibacy for priests and life-long compulsory marriage for yourself. You chose the celibacy and compulsory marriage and forgot the simplicity of Jesus' mother, who bore her child for love and love alone. You had your choice between Marx's insight into the productivity of your living labor power, which alone creates the value of commodities and the idea of the state. You forgot the living energy of your labor and chose the idea of the state. In the French Revolution, you had your choice between the cruel Robespierre and the great Danton. You chose cruelty and sent greatness and goodness to the guillotine. In Germany you had your choice between Goring and Himmler on the one hand and Liebknecht, Landau, and Muhsam on the other. You made Himmler your police chief and murdered your great friends. You had your choice between Julius Streicher and Walter Rathenau. You murdered Rathenau. You had your choice between Lodge and Wilson. You murdered Wilson. You had your choice between the cruel Inquisition and Galileo's truth. You tortured and humiliated the great Galileo, from whose inventions you are still benefiting, and now, in the twentieth century, you have brought the methods of the Inquisition to a new flowering. … Every one of your acts of smallness and meanness throws light on the boundless wretchedness of the human animal. 'Why so tragic?' you ask. 'Do you feel responsible for all evil?' With remarks like that you condemn yourself. If, little man among millions, you were to shoulder the barest fraction of your responsibility, the world would be a very different place. Your great friends wouldn't perish, struck down by your smallness.

It seems to me that you have two options: hide the fact that anything happened, or hide the fact that you had anything to do with it.

The sun had set. Night had come to the city. How easy it would be if everything went dark, and the world ended right here, right now. What a relief it would be.

In the future, there will be opened a gateway and a road to a large and excellent science into which minds more piercing than mine shall penetrate to recesses still deeper.

Lest we forget, the birth of modern physics and cosmology was achieved by Galileo, Kepler and Newton breaking free not from the close confining prison of faith (all three were believing Christians, of one sort or another) but from the enormous burden of the millennial authority of Aristotelian science. The scientific revolution of the sixteenth and seventeenth centuries was not a revival of Hellenistic science but its final defeat.

With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words, and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day. — 'Ah, so you shall be sure to be misunderstood.' — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.

I have been in my bed for five weeks, oppressed with weakness and other infirmities from which my age, seventy four years, permits me not to hope release. Added to this (proh dolor! [O misery!]) the sight of my right eye — that eye whose labors (dare I say it) have had such glorious results — is for ever lost. That of the left, which was and is imperfect, is rendered null by continual weeping.

Go on philosophers--teach, enlighten, kindle, think aloud, speak up, run joyfully toward broad daylight, fraternize in the public squares, announce the glad tidings, lavish your alphabets, proclaim human rights, sing your Marseillaises, sow enthusiasms, tear off green branches from the oak trees. Make thought a whirlwind. This multitude can be sublimated. Let us learn to avail ourselves of this vast conflagration of principles and virtues, which occasionally sparkles, bursts, and shudders. These bare feet, these naked arms, these rags, these shades of ignorance, depths of despair, the gloom can be used for the conquest of the ideal. Look through the medium of the people, and you will discern the truth. This lowly sand that you trample underfoot, if you throw it into a furnace and let it melt and seethe, will become sparkling crystal; and thanks to such as this a Galileo and a Newton will discover the stars.

He caught a glimpse of that extraordinary faculty in man, that strange, altruistic, rare, and obstinate decency which will make writers or scientists maintain their truths at the risk of death. Eppur si muove, Galileo was to say; it moves all the same. They were to be in a position to burn him if he would go on with it, with his preposterous nonsense about the earth moving round the sun, but he was to continue with the sublime assertion because there was something which he valued more than himself. The Truth. To recognize and to acknowledge What Is. That was the thing which man could do, which his English could do, his beloved, his sleeping, his now defenceless English. They might be stupid, ferocious, unpolitical, almost hopeless. But here and there, oh so seldome, oh so rare, oh so glorious, there were those all the same who would face the rack, the executioner, and even utter extinction, in the cause of something greater than themselves. Truth, that strange thing, the jest of Pilate's. Many stupid young men had thought they were dying for it, and many would continue to die for it, perhaps for a thousand years. They did not have to be right about their truth, as Galileo was to be. It was enough that they, the few and martyred, should establish a greatness, a thing above the sum of all they ignorantly had.

To our natural and human reason, I say that these terms ‘large,’ ‘small,’ ‘immense,’ ‘minute,’ etc. are not absolute but relative; the same thing in comparison with various others may be called at one time ‘immense’ and at another ‘imperceptible.

If the people of Europe had known as much of astronomy and geology when the bible was introduced among them, as they do now, there never could have been one believer in the doctrine of inspiration. If the writers of the various parts of the bible had known as much about the sciences as is now known by every intelligent man, the book never could have been written. It was produced by ignorance, and has been believed and defended by its author. It has lost power in the proportion that man has gained knowledge. A few years ago, this book was appealed to in the settlement of all scientific questions; but now, even the clergy confess that in such matters, it has ceased to speak with the voice of authority. For the establishment of facts, the word of man is now considered far better than the word of God. In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler. All that God told Moses, admitting the entire account to be true, is dust and ashes compared to the discoveries of Descartes, Laplace, and Humboldt. In matters of fact, the bible has ceased to be regarded as a standard. Science has succeeded in breaking the chains of theology. A few years ago, Science endeavored to show that it was not inconsistent with the bible. The tables have been turned, and now, Religion is endeavoring to prove that the bible is not inconsistent with Science. The standard has been changed.

Since knowledge, thinking, and rational action are properties of the individual, since the choice to exercise his rational faculty or not depends on the individual, man’s survival requires that those who think be free of the interference of those who don’t. Since men are neither omniscient nor infallible, they must be free to agree or disagree, to cooperate or to pursue their own independent course, each according to his own rational judgment. Freedom is the fundamental requirement of man’s mind. A rational mind does not work under compulsion; it does not subordinate its grasp of reality to anyone’s orders, directives, or controls; it does not sacrifice its knowledge, its view of the truth, to anyone’s opinions, threats, wishes, plans, or “welfare.” Such a mind may be hampered by others, it may be silenced, proscribed, imprisoned, or destroyed; it cannot be forced; a gun is not an argument. (An example and symbol of this attitude is Galileo.) It is from the work and the inviolate integrity of such minds—from the intransigent innovators—that all of mankind’s knowledge and achievements have come. (See The Fountainhead.) It is to such minds that mankind owes its survival. (See Atlas Shrugged.)

Kusanagi had met plenty of good, admirable people who’d been turned into murderers by circumstance. There was something about them he always seemed to sense, an aura that they shared. Somehow, their transgression freed them from the confines of a mortal existence, allowing them to perceive the great truths of the universe. At the same time, it meant they had one foot in forbidden territory. They straddled the line between sanity and madness.

. . . we come astonishingly close to the mystical beliefs of Pythagoras and his followers who attempted to submit all of life to the sovereignty of numbers. Many of our psychologists, sociologists, economists and other latter-day cabalists will have numbers to tell them the truth or they will have nothing. . . . We must remember that Galileo merely said that the language of nature is written in mathematics. He did not say that everything is. And even the truth about nature need not be expressed in mathematics. For most of human history, the language of nature has been the language of myth and ritual. These forms, one might add, had the virtues of leaving nature unthreatened and of encouraging the belief that human beings are part of it. It hardly befits a people who stand ready to blow up the planet to praise themselves too vigorously for having found the true way to talk about nature.

His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic? We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected.

BERENGER: And you consider all this natural? 

DUDARD: What could be more natural than a rhinoceros? 

 BERENGER: Yes, but for a man to turn into a rhinoceros is abnormal beyond question. 

DUDARD: Well, of course, that's a matter of opinion ... 

 BERENGER: It is beyond question, absolutely beyond question! 
DUDARD: You seem very sure of yourself. Who can say where the normal stops and the abnormal begins? Can you personally define these conceptions of normality and abnormality? Nobody has solved this problem yet, either medically or philosophically. You ought to know that. 

 BERENGER: The problem may not be resolved philosophically -- but in practice it's simple. They may prove there's no such thing as movement ... and then you start walking ... [he starts walking up and down the room] ... and you go on walking, and you say to yourself, like Galileo, 'E pur si muove' ... 

 DUDARD: You're getting things all mixed up! Don't confuse the issue. In Galileo's case it was the opposite: theoretic and scientific thought proving itself superior to mass opinion and dogmatism. 

 BERENGER: [quite lost] What does all that mean? Mass opinion, dogmatism -- they're just words! I may be mixing everything up in my head but you're losing yours. You don't know what's normal and what isn't any more. I couldn't care less about Galileo ... I don't give a damn about Galileo. 

 DUDARD: You brought him up in the first place and raised the whole question, saying that practice always had the last word. Maybe it does, but only when it proceeds from theory! The history of thought and science proves that. BERENGER: [more and more furious] It doesn't prove anything of the sort! It's all gibberish, utter lunacy! 

DUDARD: There again we need to define exactly what we mean by lunacy ... 

 BERENGER: Lunacy is lunacy and that's all there is to it! Everybody knows what lunacy is. And what about the rhinoceroses -- are they practice or are they theory?

Is it possible that the Pentateuch could not have been written by uninspired men? that the assistance of God was necessary to produce these books? Is it possible that Galilei ascertained the mechanical principles of 'Virtual Velocity,' the laws of falling bodies and of all motion; that Copernicus ascertained the true position of the earth and accounted for all celestial phenomena; that Kepler discovered his three laws—discoveries of such importance that the 8th of May, 1618, may be called the birth-day of modern science; that Newton gave to the world the Method of Fluxions, the Theory of Universal Gravitation, and the Decomposition of Light; that Euclid, Cavalieri, Descartes, and Leibniz, almost completed the science of mathematics; that all the discoveries in optics, hydrostatics, pneumatics and chemistry, the experiments, discoveries, and inventions of Galvani, Volta, Franklin and Morse, of Trevithick, Watt and Fulton and of all the pioneers of progress—that all this was accomplished by uninspired men, while the writer of the Pentateuch was directed and inspired by an infinite God? Is it possible that the codes of China, India, Egypt, Greece and Rome were made by man, and that the laws recorded in the Pentateuch were alone given by God? Is it possible that Æschylus and Shakespeare, Burns, and Beranger, Goethe and Schiller, and all the poets of the world, and all their wondrous tragedies and songs are but the work of men, while no intelligence except the infinite God could be the author of the Pentateuch? Is it possible that of all the books that crowd the libraries of the world, the books of science, fiction, history and song, that all save only one, have been produced by man? Is it possible that of all these, the bible only is the work of God?

With the best of intentions, the generation before mine worked diligently to prepare their children to make an intelligent case for Christianity. We were constantly reminded of the superiority of our own worldview and the shortcomings of all others. We learned that as Christians, we alone had access to absolute truth and could win any argument. The appropriate Bible verses were picked out for us, the opposing positions summarized for us, and the best responses articulated for us, so that we wouldn’t have to struggle through two thousand years of theological deliberations and debates but could get right to the bottom line on the important stuff: the deity of Christ, the nature of the Trinity, the role and interpretation of Scripture, and the fundamentals of Christianity. As a result, many of us entered the world with both an unparalleled level of conviction and a crippling lack of curiosity. So ready with the answers, we didn’t know what the questions were anymore. So prepared to defend the faith, we missed the thrill of discovering it for ourselves. So convinced we had God right, it never occurred to us that we might be wrong. In short, we never learned to doubt. Doubt is a difficult animal to master because it requires that we learn the difference between doubting God and doubting what we believe about God. The former has the potential to destroy faith; the latter has the power to enrich and refine it. The former is a vice; the latter a virtue. Where would we be if the apostle Peter had not doubted the necessity of food laws, or if Martin Luther had not doubted the notion that salvation can be purchased? What if Galileo had simply accepted church-instituted cosmology paradigms, or William Wilberforce the condition of slavery? We do an injustice to the intricacies and shadings of Christian history when we gloss over the struggles, when we read Paul’s epistles or Saint Augustine’s Confessions without acknowledging the difficult questions that these believers asked and the agony with which they often asked them. If I’ve learned anything over the past five years, it’s that doubt is the mechanism by which faith evolves. It helps us cast off false fundamentals so that we can recover what has been lost or embrace what is new. It is a refining fire, a hot flame that keeps our faith alive and moving and bubbling about, where certainty would only freeze it on the spot. I would argue that healthy doubt (questioning one’s beliefs) is perhaps the best defense against unhealthy doubt (questioning God). When we know how to make a distinction between our ideas about God and God himself, our faith remains safe when one of those ideas is seriously challenged. When we recognize that our theology is not the moon but rather a finger pointing at the moon, we enjoy the freedom of questioning it from time to time. We can say, as Tennyson said, Our little systems have their day; They have their day and cease to be; They are but broken lights of thee, And thou, O Lord, art more than they.15 I sometimes wonder if I might have spent fewer nights in angry, resentful prayer if only I’d known that my little systems — my theology, my presuppositions, my beliefs, even my fundamentals — were but broken lights of a holy, transcendent God. I wish I had known to question them, not him. What my generation is learning the hard way is that faith is not about defending conquered ground but about discovering new territory. Faith isn’t about being right, or settling down, or refusing to change. Faith is a journey, and every generation contributes its own sketches to the map. I’ve got miles and miles to go on this journey, but I think I can see Jesus up ahead.

After an injunction had been judicially intimated to me by this Holy Office, to the effect that I must altogether abandon the false opinion that the sun is the center of the world and immovable, and that the earth is not the center of the world, and moves, and that I must not hold, defend, or teach in any way whatsoever, verbally or in writing, the said false doctrine, and after it had been notified to me that the said doctrine was contrary to Holy Scripture — I wrote and printed a book in which I discuss this new doctrine already condemned, and adduce arguments of great cogency in its favor, without presenting any solution of these, and for this reason I have been pronounced by the Holy Office to be vehemently suspected of heresy, that is to say, of having held and believed that the Sun is the center of the world and immovable, and that the earth is not the center and moves: Therefore, desiring to remove from the minds of your Eminences, and of all faithful Christians, this vehement suspicion, justly conceived against me, with sincere heart and unfeigned faith I abjure, curse, and detest the aforesaid errors and heresies, and generally every other error, heresy, and sect whatsoever contrary to the said Holy Church, and I swear that in the future I will never again say or assert, verbally or in writing, anything that might furnish occasion for a similar suspicion regarding me; but that should I know any heretic, or person suspected of heresy, I will denounce him to this Holy Office, or to the Inquisitor or Ordinary of the place where I may be. Further, I swear and promise to fulfill and observe in their integrity all penances that have been, or that shall be, imposed upon me by this Holy Office. And, in the event of my contravening, any of these my promises and oaths, I submit myself to all the pains and penalties imposed and promulgated in the sacred canons and other constitutions, general and particular, against such delinquents.
