Quotes & Sayings About Irreversible

Something escapes us, and we are escaping from ourselves, or losing ourselves, as part of an irreversible process; we have now passed some point of no return, the point where the contradictoriness of things ended, and we find ourselves, still alive, in a universe of non-contradiction, of enthusiasm, of ecstasy - of stupor in the face of a process which, for all its irreversibility, is bereft of meaning. — Jean Baudrillard

Most business mistakes are irreversible setbacks, but you get another chance. There are two things in life that you don't get another chance at - marrying the wrong person and what you do with your children. — Warren Buffett

If left unchecked, global change will create violent conflict, torrential storms, shrinking coastlines, and irreversible catastrophe. — Valerie Jarrett

The spectacle is nothing more than the common language of this separation. What binds the spectators together is no more than an irreversible relation at the very center which maintains their isolation. The spectacle reunites the separate, but reunites it as separate. — Guy Debord

Though I am fully aware that it was an act of desperation after the sun flares, releasing the Flare virus as a means of population control was an abhorrent and irreversible crime. — James Dashner

Rape is a crime against sleep and memory; it's afterimage imprints itself like an irreversible negative from the camera obscura of dreams. — Pat Conroy

We have chosen to bring future generations into this world of rising seas and warming temperatures, droughts and floods, heat waves and wildfires, a world in which one in four mammals and one in eight birds are at risk of disappearing forever. While the damage we've done is irreversible, that doesn't give us the right to do nothing. — Leonor Varela

The security fence is reversible. Human lives are irreversible. — Silvan Shalom

Death is real, irreversible, and awful. Do you want some advice? Don't wait until you're dead to try to communicate. Do it now. You still have a chance. Not a great one, but a better one than you will have. If you think it's hard to get your point across now, and that no one really understands what you're about, just try it when you're dead. — Alexander Jablokov

It is hard to have patience with people who say, 'There is no death' or 'Death doesn't matter.' There is death. And whatever is matters. And whatever happens has consequences, and it and they are irrevocable and irreversible. You might as wel say that birth doesn't matter. — C.S. Lewis

In five years' time at this pace global warming becomes irreversible. — Yosef Abramowitz

Textbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible. But today I want to present it as something different again, and even more intriguing. The DNA in you is a coded description of ancient worlds in which your ancestors lived. DNA is the wisdom out of the old days, and I mean very old days indeed. — Richard Dawkins

My favorite film score is the one Thomas Bangalter created for 'Irreversible.' The soundtrack absolutely defines the daymare-into-nightmare feeling you get from the film. — Richard Phillips

We have made mistakes. In our haste to do all things for all people, we did not foresee the full consequences of our actions. And when the people raised their voices, we didn't hear. But our deafness was only a temporary condition, and not an irreversible condition. — Barbara Jordan

[A] group of leading academics argue that humanity must stay within defined boundaries for a range of essential Earth-system processes to avoid catastrophic environmental change. . . . They propose that for three of these - the nitrogen cycle, the rate of loss of species and anthropogenic climate change - the maximum acceptable limit has already been transgressed. In addition, they say that humanity is fast approaching the boundaries for freshwater use, for converting forests and other natural ecosystems to cropland and urban areas, and for acidification of the oceans. Crossing even one of these planetary boundaries would risk triggering abrupt or irreversible environmental changes that would be very damaging or even catastrophic for society. — Jonathan A. Moo

Activity proneness in the service of an ideology ... leads the individual into an irreversible series of commitments from which is forged an identity to which the individual inevitably becomes strongly attached psychologically. — Edgar Schein

The future will belong to the Germans ... when we build the House of Europe. In the next two years, we will make the process of European integration irreversible. This is a really big battle but it is worth the fight. — Helmut Kohl

In their eyes I must have appeared like some kind of nightmarish totem, a domestic idiot suffering from the irreversible brain damage of a motorway accident and now put out each morning to view the scene of his own cerebral death. — J.G. Ballard

Today we are experiencing a historical revolution every bit as wrenching, far-reaching, and irreversible as the Industrial Revolution. Like that huge historic turning point, the revolution in marriage has transformed how people organize their work and interpersonal commitments, use their leisure time, understand their sexuality, and take care of children and the elderly. It has liberated some people from restrictive, inherited roles in society. But it has stripped others of traditional support systems and rules of behavior without establishing new ones. — Stephanie Coontz

Humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel. This has resulted in a substantial and largely irreversible loss in the diversity of life on Earth. — Gary Larson

(1) irreversible processes are as real as reversible ones. (2) irreversible processes play a fundamental constructive role in the physical world. (3) irreversibility is deeply rooted in dynamics. — Ilya Prigogine

With all these forks in the roads of our path, why do so many choose to take the knife? — Anthony Liccione

The revolutionary process by which all books, old and new, in all languages, will soon be available digitally, at practically no cost for storage and delivery, to a radically decentralized world-wide market at the click of a mouse, is irreversible. — Jason Epstein

Salty tears stream down my face - coating my lips as I mutter senseless apologies for so many things. So many irreversible things.
Morpheus peels the vines off and lifts me, cradling me to his chest. — A.G. Howard

Every act of irreverence for life, every act which neglects life, which is indifferent to and wastes life, is a step towards the love of death. This choice man must make at every minute. Never were the consequences of the wrong choice as total and as irreversible as they are today. Never was the warning of the Bible so urgent: 'I have put before you life and death, blessing and curse. Choose life, that you and your children may live.' — Erich Fromm

I told myself that in the country of my birth, from which I was disengaged in an increasingly irreversible way, there undoubtedly were many men and women like him, basically decent people who had dreamed all their lives of the economic, social, cultural, and political progress that would transform Peru into a modern, prosperous, democratic society with opportunities open to all, only to find themselves repeatedly frustrated, and, like Uncle Ataulfo, had reached old age - the very brink of death - bewildered, asking themselves why we were moving backward instead of advancing and were worse off now with more discrimination, inequality, violence, and insecurity than when they were starting out — Edith Grossman

The Kyoto Treaty wasn't perfect, but we signed it, in fact, helped to draft it. And I'm very proud of it, it was the world's first commitment to doing something comprehensive on greenhouse gases and trying to reduce global warming before we do irreversible damage to many civilizations around the world. — William J. Clinton

I'm surprised Cole let you stay. What we do here is slightly unconventional." Bea looked suspicious and in-the-know at the same time.
"I'm in love with his brother." Saying this out loud to Bea felt like jumping out of an airplane - thrilling and irreversible. In that instant Livia knew her love for Blake was as real as the church walls around her.
Bea took in Livia's face with wise eyes. "Why, yes. Yes you are. — Debra Anastasia

Constitutional democracy has created astonishing and apparently irreversible social progress. All we're interested in is talking about when government doesn't work. — Tony Kushner

Please consult your child's Witch doctor before using this product. Diapers may cause severe allergies, internal bleeding, and irreversible sex change. — Kenya Wright

How could people, I wondered for the ten thousandth useless time, how could people who had loved so dearly come to such a wilderness; and yet the change in us was irreversible, and neither of us would even search for a way back. It was impossible. The fire was out. Only a few live coals lurked in the ashes, searing unexpectedly at the incautious touch. — Dick Francis

I felt knots untie themselves, knots I didn't know were there. I could already tell there were things happening deep inside of me that were irreversible. Is there any scarier word than "irreversible"? It's a hiss of a word, full of side effects and mutilations. Severe tire damage - no backing up. Falling in love with Renee felt that way. — Rob Sheffield

It was a gorgeous calamity in scale, I thought. A lovely misfortune. Immediate and irreversible and very soon forgotten. We needed more troubles like that. Ones like burning supper or coming down with a head cold at an awkward time. I desperately wanted to pass through countless small, endurable problems with the girl sitting next to me. I didn't need much else. — Lyndsay Faye

We are of the opinion that an important and irreversible process is taking place among the white population. Just as with the blacks, the whites, too, are currently overcoming a psychological barrier. — Joe Slovo

each of us humans has a moment-if not many-in which we lapse. for some, the transgression involves sex. for others, simply doubt or a rage so all encompassing, it impels us to make irreversible decisions.
but whatever the transgression is doesn't really matter. what matters is that lapsing is our fate. we humans are doomed to it. worse, it is our destiny to look back longingly, with nostalgia, at our world before we changed, at who we were Before.
we can never forget.
but we can never go back. — Miranda Beverly-Whittemore

This is the enemy, what is irreversible, what has already reached the farthest of places. There is no going back. They can bomb bus-loads of tourists, burn the American flag, but they are not shooting the enemy. It is already with them, inside them, what makes them resentful, defensive, what makes them no longer confident of their vision of the world. — Leila Aboulela

Once, I discovered the skulls of two impala rams, their horns locked into an irreversible figure-of-eight; the two animals had been trapped in combat, latched to each other during the battle of the rut. The harder they had pulled to escape from each other, the more intractably stuck they were, until they had fallen exhausted, to their knees, in an embrace of hatred that had killed them both. When I picked up the skulls to add to my growing collection of what Vanessa called "Bobo's smelly pile," the hooked horns fell away from each other and the story of the impalas' death struggle was undone. — Alexandra Fuller

Women's liberation, if not the most extreme then certainly the most influential neo-Marxist movement in America, has done to the American home what communism did to the Russian economy, and most of the ruin is irreversible. By defining relations between men and women in terms of power and competition instead of reciprocity and cooperation, the movement tore apart the most basic and fragile contract in human society, the unit from which all other social institutions draw their strength. — Ruth Wisse

The "mood of the nation," in 1972, was so overwhelmingly vengeful, greedy, bigoted, and blindly reactionary that no presidential candidate who even faintly reminded "typical voters" of the fear & anxiety they'd felt during the constant "social upheavals" of the 1960s had any chance at all of beating Nixon last year--not even Ted Kennedy--because the pendulum "effect" that began with Nixon's slim victory in '68 was totally irreversible by 1972. After a decade of left-bent chaos, the Silent Majority was so deep in a behavorial sink that their only feeling for politics was a powerful sense of revulsion. All they wanted in the White House was a man who would leave them alone and do anything necessary to bring calmness back into their lives — Hunter S. Thompson

But you are not one of us. For you, this thing is irreversible except by death, and not only the flesh is altered. Only the strongest of you can resist the collapse of the soul into the form; the mind is lazy, it naturally imitates the body. I have known none of you yet who can remain human when they wear another skin. But the thing is yours to do, if you should wish to do it. — Catherynne M Valente

In an ultimate sense I cannot know what I do in this place - yet I do ultimate things. Essentially I cannot know what I do - yet I do essential things. Irreversible, terminal things. I stand in the dark with a pick in my hand, striking at heads! I need - more desperately than my children need me - a way of seeing in the dark. — Peter Shaffer

Once it builds up in the victim's system, a threshold is reached, the organs begin to fail, and the degeneration is irreversible. It's not a killer. It's a thief. It steals years. And he will never get them back.
I felt a little chill at the satisfaction in her voice. — Leigh Bardugo

He was wise in the ways of pain. He had to be, for he felt none.

When the Xenons put electrodes to his testicles, he was vastly entertained by the pretty lights.

When the Ylls fed firewasps into his nostrils and other body orifices the resultant rainbows pleased him. And when later they regressed to simple disjointments and eviscerations, he noted with interest the deepening orchid hues that stood for irreversible harm.

"This time?" he asked the boditech when his scouter had torn him from the Ylls.

"No," said the boditech.

"When?"

There was no answer.

"You're a girl in there, aren't you? A human girl?"

"Well, yes and no," said the boditech. "Sleep now."

He had no choice.

- 'Painwise — James Tiptree Jr.

No victory is irreversible, no defeat is definitive. That is what makes life worth living. — Leszek Kolakowski

Noah had 120 years to warn humanity of the flood. We have only 4-5 years until global warming is irreversible — Yosef Abramowitz

The greatest danger hanging over our children and grandchildren is initiation of changes that will be irreversible on any time scale that humans can imagine. — James Hansen

We see a newborn moth unwrapping itself and announce, Look, children, a miracle! But let an irreversible wound be knit back to seamlessness? We won't even see it, though we look at it every day. — Leif Enger

[Richard Avedon's] camera dwells on the horrible things that age can do to people's faces - on the flabby flesh, the slack skin, the ugly growths, the puffy eyes, the knotted necks, the aimless wrinkles, the fearful and anxious set of the mouth, the marks left by sickness, madness, alcoholism, and irreversible disappointment. — Janet Malcolm

Encased in an elaborate illusion of unlimited power and progress, each of us subscribes, at least until one's midlife crisis, to the belief that existence consists of an eternal, upward spiral of achievement, dependent on will alone.
This comforting illusion may be shattered by some urgent irreversible experience ... None more potently confronts us with finiteness and contingency than the imminence of our own death. — Irvin D. Yalom

Nothing in the world is irreversible, not even capitalism. — Fidel Castro

The siren song of redistribution of wealth by centralized government never ceases for those who seek irreversible and unusurpable control over the lives and liberties of private citizens. — Josh Jones

I had no evidence. No physical signs of my rape existed anymore. My body had already purged them. That was the irreversible reality. — Aspen Matis

Tocqueville already explained, more than 150 years ago, that democracies are short-sighted and are not systems well adapted to long-term challenges. He explained perfectly how democracies bring individualism and mass consumption. Democracies can respond to immediate threats, like war. But do democracies exist that are capable of dealing with an insidious but irreversible danger? This is an open question. — Guillaume Faye

The people who work within these industries or public services know that there are basic flaws. But they are almost forced to ignore them and to concentrate instead on patching here, improving there, fighting the fire or caulking that crack. They are thus unable to take the innovation seriously, let alone to try to compete with it. They do not, as a rule, even notice it until it has grown so big as to encroach on their industry or service, by which time it has become irreversible. In the meantime, the innovators have the field to themselves. — Peter F. Drucker

The Alexander Technique keeps the body alive, at ages when many people have resigned themselves to irreversible decline. — Robertson Davies

Adrianna tried to deal with a lot of grown up issues on her own and fell into some bad traps that could have had irreversible results. I would like to say to anyone who finds themselves in a predicament similar to young Adrianna's, it is important to seek help from someone you can trust. Even though she had reservations discussing her problems with others, there is nothing shameful in seeking guidance for problems you or someone you know may be having. Like Adrianna, you may have many people around you who are willing to help, such as a family member, coach, teacher, guidance counselor, or others. You will find that facing your problems with the help of others will make life much more enjoyable. — Vicki L. Drewa

Death was irreversible, he suspected, and he began to think he was going to lose — Joseph Heller

Both David and Marcus, I came to realize, though they seemed happy enough, and looked forward to being doctors, had a certain sadness, a sense of loss and renunciation, about other interests they had given up.... Both became medical students, in part, to defer their call-up. But with this, I think, they deferred their other aspirations, a deferment that seemed permanent and irreversible by the time they returned to London. — Oliver Sacks

Of course he knew what kinds of thoughts these were: the not-always-true ones, conveniently forgetting the other times, when he and Christine had bickered at the smallest thing, aggravated by the other's mere constant presence, and sometimes even said awful things
irreversible and stinging
that lingered like a foul odor for a long time afterward. Then there were long stretches of calm. And yet the bickering, the irritation, that too was part of the delicate glue that kept them together, still feeling something, even when they grew, sometimes for long periods, bored with each other, tired of each other, before settling back into their more usual, tamed and tamped down but still real and extant love. — Daphne Kalotay

Rome wasn't built in a day, and we won't replace fossil fuels with clean energy based on the events of a single week, either. But the important thing to remember is that, once they happen, clean energy victories are irreversible. No one will tear down wind farms because they are nostalgic for fracking in our watersheds. And nobody will pull down their solar panels because they miss having mercury in their tuna or asthma inhalers for their kids. Because once we leave fossil fuels behind, we are never going back. — Michael Brune

Every word, every step, every action is irreversible. If we step in front of a moving car, if we sign a contract we haven't read, if we betray the person we love, the best we can do is try to clean up the mess. But no matter how hard we scrub, the stain on reality will never come out. The word you just read can never be unread. — Neil Strauss

The hippocampus is the structure where memory is supposedly controlled. It is the most plastic part of the brain; it is also the part that is assumed to absorb all the damage from repeated insults like the chronic stress we experience daily from small doses of negative feelings - as opposed to the invigorating "good stress" of the tiger popping up occasionally in your living room. You can rationalize all you want; the hippocampus takes the insult of chronic stress seriously, incurring irreversible atrophy. Contrary to popular belief, these small, seemingly harmless stressors do not strengthen you; they can amputate part of your self. — Nassim Nicholas Taleb

Leave the broken, irreversible past in God's hands, and step out into the invincible future with Him. — Oswald Chambers

Irreversible is not glamorous at all. I try to do different things because I want to grow as an actress and I like to take risks. — Monica Bellucci

It means joining with allies to deploy renewable energy technologies
both at home and around the world
to confront the very real and present danger of potentially irreversible climate change. — Bernie Sanders

Space hurls outwards, falconswift, mounting like an irreversible justice, a final disease — John Gardner

We suddenly feel fearful and apprehensive, naked in our perishable flesh, and for just a moment we wish we could go back to being stone - crumbling in death rather than rotting, trapped inside an immobile prison of stone rather than reduced to immaterial souls like those that now rattled within our skulls. The moment passes. There is no point in regretting irreversible decisions - one has to live with them, and we try. — Ekaterina Sedia

Do other people, remembering their parents, feel, as I do, a sense of having inadvertently done a small though significant, irreversible wrong? — John Banville

Maybe there is something. Something deep. Something in border of physical and incomprehensible. Something unknowable.
Something completely beyond of all psychological, logical and scientific definitions about human. Something, for which the death is no irreversible limit.Something so strange and absurd.
Something infinite and eternal in Homo Sapiens. Never - dying fire.
The human spirit. — Alexandar Tomov

There is no question that if one were to ask whether we Americans are moving towards more liberty or more government control over our lives, the answer would unambiguously be the latter - more government control over our lives. We might have reached a point where the trend is irreversible and that is a true tragedy for if liberty is lost in America, it will be lost for all times and all places. — Walter E. Williams

Man's natural desire is to better oneself. But when does this admirable attribute become a wedge in the growing tree of progress, destined for irreversible and devastating consequences? We see such monstrous consequences come to fruition over and over throughout history. When fire is not contained, the whole land will burn. — Johan Twiss

We have won so many contests, leveled so many barriers, that the changes wrought by the women's movement are widely viewed as irreversible, even by feminism's most committed antagonists. Yet, as women near the finish line, we are distracted. We have stopped to gather glittery trinkets from an apparent admirer. The admirer is the marketplace, and the trinkets are the bounty of a commercial culture, which has deployed the language of liberation as a new and powerful tool of subjugation. — Susan Faludi

The taking of life is too absolute, too irreversible, for one human being to inflict on another, even when backed by legal process ... Where the death penalty persists, conditions for those awaiting execution are often horrifying, leading to aggravated suffering. — Ban Ki-moon

Let the separation between you and the world be final and irreversible. Say, 'Here I go for Christ and His Cross, for the faith of the Bible, for the laws of God, for holiness, for trust in Jesus; and never will I go back, come what may. — Charles Spurgeon

One thing is obvious: Our policy, which is directed at making the country ungovernable, has started to bear fruit. The process that has been initiated is irreversible. — Joe Slovo

Time is life. It is irreversible and irreplaceable. To waste your time is to waste your life, but to master your time is to master your life and make the most of it. — Alan Lakein

What politicians want to create is irreversible change because when you leave office someone changes it back again. — Estelle Morris

Before it's too late, we need to make courageous choices that will recreate a strong alliance between man and Earth. We need a decisive 'yes' to care for creation and a strong commitment to reverse those trends that risk making the situation of decay irreversible. — Pope Benedict XVI

From that moment on, there will be an irreversible process to separate Quebec from Canada. — Jean Charest

Language and material culture have greatly increased the mobility of the world's population, and some researchers believe that this will lead to an unhealthy and irreversible diminishing of variation in our genome. As more and more humans breed across the boundaries of genetic variation, we become a blander, more homogenous bunch than our diverse parent groups. This could be a problem because variation is important to the evolutionary health of a species, for the more we are the same, the easier it is for one single thing to make us extinct. Indeed, some genetic variants of the human species are disappearing altogether as small indigenous groups die out. — Christine Kenneally

Three, 300, or 3,000 - these are the number of unknown days, a week, a year, or a decade, each far too precious little and yet, poignantly too much at the same time, to see an irrevocably declined loved one languish and suffer. That fear-ridden, irreversible release lingers in the doorway, but hesitates for reasons we don't understand, leaving us to weep with a mixture of angst and gratitude all at the same time. It is finally ushered all the way in, to comfort and carry our loved one to that Better Place. When the time finally comes, we can be enveloped in a warm cloak of long-awaited acceptance and peace that eases our own pain. It quiets the grief which has moaned inside of us, at least some, every single one of those bittersweet days, weeks... or years. — Connie Kerbs

Historical chronology, human or geological, depends ... upon comparable impersonal principles. If one scribes with a stylus on a plate of wet clay two marks, the second crossing the first, another person on examining these marks can tell unambiguously which was made first and which second, because the latter event irreversibly disturbs its predecessor. In virtue of the fact that most of the rocks of the earth contain imprints of a succession of such irreversible events, an unambiguous working out of the chronological sequence of these events becomes possible. — M. King Hubbert

Life is an irreversible process and for that reason its future can never be a repetition of the past. — Walter Lippmann

Carroting, you must understand, was a process by which animal fur is bathed in a solution of mercury nitrate, in order to render the hairs more supple, thus producing a superior felt." At this last word, he threw a significant glance in my direction. "Felt," I repeated. "You mean, for the making of hats?" "Precisely. The solution is of an orange colour, hence the term carroting. However, this process had rather severe side effects on those who worked with it, which is why its use today is much reduced. When mercury vapours are inhaled over a long enough period of time - particularly, for our purposes, in the close quarters of a hat-making operation - toxic and irreversible effects almost inevitably follow. One develops tremors of the hands; blackened teeth; slurred speech. In severe cases, dementia or outright insanity can occur. Hence the term mad as a hatter. — Douglas Preston

Cruelty signifies rigor, implacable intention and decision, irreversible and absolute determination, — Antonin Artaud

It's cool when fashion recycles itself, it's not cool when sustainable living does because it means there was (and is as I write) a period of absolute and possibly irreversible destruction. — Cameron Conaway

There are no steps to self-realization. There is nothing gradual about it. It happens suddenly and is irreversible. You rotate into a new dimension, seen from which the previous ones are mere abstractions. Just like on sunrise you see things as they are, so on self-realization you see everything as it is. The world of illusions is left behind. — Sri Nisargadatta Maharaj

I've been working on my honesty this summer. I've told such a big lie, such a massively irreversible one, that I figure I need to somehow even the score. But the thing about lying is that it's not so easy to stop. Lies need one another, like a school of fish. If you start to separate them, they'll be killed off one by one. Sometimes the only way to keep lies alive is to tell more of them. — Rebecca Serle

If you were searching. I also would have left a small indication that something so important, something so critical to your soul has disappeared. The sole reason a constellation exists is because it's a sum of its parts. To lose one of those parts ... it's painful and irreversible. — Katie McGarry

There was someplace urgent he needed to be, and he wasn't going to make it there on time. It was a gorgeous calamity in scale, I thought. A lovely misfortune. Immediate and irreversible and very soon forgotten. We needed more troubles like that. — Lyndsay Faye

I like a movie that brings out many discussions. From my experience, every time I have done movies, they create this kind of situation. Like 'Irreversible,' 'The Passion of the Christ,' 'Malena'; it's so interesting. I like to explore the dark side of humanity. That's why I'm an actor. — Monica Bellucci

Each man lives for himself, uses his freedom to achieve his personal goals, and feels with his whole being that right now he can or cannot do such-and-such an action; but as soon as he does it, this action, committed at a certain moment in time, becomes irreversible, and makes itself the property of history, in which is has not a free but a predestined significance. — Leo Tolstoy

Ahead lies only the irreversible long decline. For the first time we know there is nothing beyond ourselves. — James Tiptree Jr.

In life we often end up finding ourself in a situation we thought we would never see. Good or bad deal with it. If you wish you could go back remember time is irreversible, whats done cannot be undone. Never regret but learn. What will be is in your hands. Live for now live today and things will fall in place. — Mansi Soni

Blue had never believed in death until then. Not in a real way. It happened to other people, other families, in other places. It happened in hospitals or automobile crashes or battle zones. It happened
now she remembered Gansey's words outside Gwenllian's tomb
with ceremony. With some announcement of itself. It didn't just happen in the attic on a sunny day while she was sitting in the reading room. It didn't just HAPPEN, in only a moment, an irreversible moment. It didn't happen to people she had always known. But it did. And there would now forever be two Blues: the Blue that was before, and the Blue that was after. The one who didn't believe, and the one who did. — Maggie Stiefvater

Nothing we do is inevitable, but everything we do is irreversible. — Joy Williams

If we define risk as 'the likelihood of an irreversible negative outcome,' inaction is the greatest risk of all. — Tim Ferriss

It is dangerous to build systemic reforms on a close association with one particular government. Systemic reforms need broad public participation and support. That is what makes them irreversible. — George Soros

In the use of force, one simplifies the situation by assuming that the evil to be overcome is clear-cut, definite, and irreversible. Hence there remains but one thing: to eliminate it. Any dialogue with the sinner, any question of the irreversibility of his act, only means faltering and failure. Failure to eliminate evil is itself a defeat. Anything that even remotely risks such defeat is in itself capitulation to evil. The irreversibility of evil then reaches out to contaminate even the tolerant thought of the hesitant crusader who, momentarily, doubts the total evil of the enemy he is about to eliminate. p. 21 — Thomas Merton

This moment of lucidity does not last long. But it serves as the punishment for your sins, a Promethean entrails-pecking moment, crouching half-horse half-man, with the knowledge that you cannot appreciate the destination without knowing the starting point; you cannot revel in the simplicity unless you remember the alternatives.
And that's not the worst of your revelation. You realize that the next time you return here, with your thick horse brain, you won't have the capacity to ask to become a human again. You won't understand what a human is. Your choice to slide down the intelligence ladder is irreversible. And just before you lose your final human faculties, you painfully ponder what magnificent extraterrestrial creature, enthralled with the idea of finding a simpler life, chose in the last round to become a human. — David Eagleman
