“As we understand the world better, the idea that it has a transcendent purpose seems increasingly untenable.”
“Those swirls in the cream mixing into the coffee? That’s us. Ephemeral patterns of complexity, riding a wave of increasing entropy from simple beginnings to a simple end. We should enjoy the ride.”
“Illusions can be pleasant, but the rewards of truth are enormously better.”
“The construction of meaning is a fundamentally individual, subjective, creative enterprise, and an intimidating responsibility.”
“The idea of “Ten Commandments” is a deeply compelling one. It combines two impulses that are ingrained in our nature as human beings: making lists of ten things, and telling other people how to behave.”
“Poetic naturalism is a philosophy of freedom and responsibility. The raw materials of life are given to us by the natural world, and we must work to understand them and accept the consequences. The move from description to prescription, from saying what happens to passing judgment on what should happen, is a creative one, a fundamentally human act. The world is just the world, unfolding according to the patterns of nature, free of any judgmental attributes. The world exists; beauty and goodness are things that we bring to it.”
“It doesn’t include math or logic, nor does it address issues of judgment, such as aesthetics or morality. Science has a simple goal: to figure out what the world actually is. Not all the possible ways it could be, nor the particular way it should be. Just what it is. There’s”
“The trick is to think of life as a process rather than a substance. When a candle is burning, there is a flame that clearly carries energy. When we put the candle out, the energy doesn’t “go” anywhere. The candle still contains energy in its atoms and molecules. What happens, instead, is that the process of combustion has ceased. Life is like that: it’s not “stuff”; it’s a set of things happening. When that process stops, life ends.”
“Where misunderstanding dwells, misuse will not be far behind. No theory in the history of science has been more misused and abused by cranks and charlatans—and misunderstood by people struggling in good faith with difficult ideas—than quantum mechanics.”
“Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don’t ever expect to be reunited with Carl. But, the great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief and precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting.”
“The physical notion of determinism is different from destiny or fate in a subtle but crucial way: because Laplace’s Demon doesn’t actually exist, the future may be determined by the present, but literally nobody knows what it will be.”
“Albert Szent-Györgyi, a Hungarian physiologist who won the Nobel Prize in 1937 for the discovery of vitamin C, once offered the opinion that “life is nothing but an electron looking for a place to rest.”
“Our goal over the next few chapters is to address the origin of complex structures—including, but not limited to, living creatures—in the context of the big picture. The universe is a set of quantum fields obeying equations that don’t even distinguish between past and future, much less embody any long-term goals. How in the world did something as organized as a human being ever come to be?”
“So neurons talk to each other by squirting electrically charged molecules from the axon of one to a dendrite on another.”
“Even if we don’t go as far as Descartes’s belief in an immaterial soul that somehow interacts with our body, it’s tempting to visualize a dictatorial “self” inside our brain that is the locus of our self-awareness. Philosopher Daniel Dennett coined the term “Cartesian theater” to describe the supposed mental control room containing a tiny homunculus who gathers all of the input from our sensory organs, accesses our memories, and sends out instructions to the various parts of our bodies. Consciousness”
“the lane to my left wasn’t as far back as I thought. The very last inch of my back bumper caught the very front corner of the truck’s cab. That was enough. I lost all control of my car, which executed a slow and stately counterclockwise turn, ending with my driver’s side flush into the front of the truck, still speeding down the freeway. It was slow and stately from my perspective, anyway. I felt as if I were trapped in amber, watching helplessly as my car moved of its own”
“If any particle we haven’t yet found lasted long enough and interacted with ordinary matter with sufficient strength that it could possibly affect the physics of everyday goings-on, we would have produced it in experiments by now. One”
“One is our tendency to give higher credences to propositions that we want to be true. This can show up at a very personal level, as what’s known as self-serving bias:”
“Biologists Robert Sapolsky and Lisa Share studied a group of Kenyan baboons who fed off the garbage from a nearby tourist lodge. The clan was dominated by high-status males, and females and lesser males would often go hungry. Then at one point, the clan ate infected meat from the garbage dump, which led to the deaths of most of the dominant males. Afterward, the “personality” of the troop completely changed: individuals were less aggressive, more likely to groom one another, and more egalitarian. This behavior persisted as long as the study continued, for over a decade.”
“I leave Sisyphus at the foot of the mountain! One always finds one’s burden again. But Sisyphus teaches the higher fidelity that negates the gods and raises rocks. He too concludes that all is well. This universe henceforth without a master seems to him neither sterile nor futile. Each atom of that stone, each mineral flake of that night-filled mountain, in itself forms a world. The struggle itself toward the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.”
“Alfred P. Sloan Foundation, the David and Lucile Packard Foundation, the American Physical Society, the American Institute of Physics, and the Royal Society of London. His most recent award was a Guggenheim Fellowship in 2015. He is the author of From Eternity to Here and”
“Nothingness, after all, is simpler than any one particular existing thing ever could be; there is only one nothing, and many kinds of something.”
“The mistake we make in putting emphasis on happiness is to forget that life is a process, defined by activity and motion, and to search instead for the one perfect state of being. There can be no such state, since change is the essence of life. Scholars who study meaning in life distinguish between synchronic meaning and diachronic meaning. Synchronic meaning depends on your state of being at any one moment in time: you are happy because you are out in the sunshine. Diachronic meaning depends on the journey you are on: you are happy because you are making progress toward a college degree. If we permit ourselves to take inspiration from what we have learned about ontology, it might suggest that we focus more on diachronic meaning at the expense of synchronic. The essence of life is change, and we can aim to make change part of how we find meaning in it.”
“If an ontology predicts almost nothing it ends up explaining almost nothing, and there's no reason to believe it.”
“In 1965, physicist Richard Feynman opined, “I think I can safely say that nobody understands quantum mechanics,” and the sentiment is equally applicable today.”
“Life is a process, not a substance, and it is necessarily temporary. We are not the reason for the existence of the universe, but our ability for self-awareness and reflection makes us special within it. This”
“When we want something to be true, when a belief makes us happy—that’s precisely when we should be questioning. Illusions can be pleasant, but the rewards of truth are enormously greater.”
“Life is not a substance, like water or rock; it’s a process, like fire or a wave crashing on the shore. It’s a process that begins, lasts for a while, and ultimately ends. Long or short, our moments are brief against the expanse of eternity.”
“By themselves, those particles and forces don’t have the capability of supporting the psychic phenomena that so fascinated my twelve-year-old self. More important, we know that there aren’t new particles or forces out there yet to be discovered that would support them. Not simply because we haven’t found them yet, but because we definitely would have found them if they had the right characteristics to give us the requisite powers. We know enough to draw very powerful conclusions about the limits of what we can do.”
“The idea of "Ten Commandments" is a deeply compelling one. It combines two impulses that are ingrained in our nature as human beings: making lists of ten things, and telling other people how to behave.”
“If you hurt me, I wouldn't cry. I would hurt you back.”
“No Longer Mine
It should be my right to mourn someone who has yet to leave this world but no longer wants to be part of mine.”
“This new generation, they’ve been raised by their parents to assume they’ll start at the top. No scut for them. They’ll just sit in their parents’ basement till the job offer for partner comes in.”
“She'd grown up inside books. No matter how dark life became, shutting out the hurt was as easy as opening a cover. A child of murdered parents and a failed rebellion, she'd still walked in the boots of scholars and warriors, queens and conquerors.
The heavens grant us only one life, but through books, we live a thousand.”
“Other people’s judgments were meaningless unless you allowed them to mean something.”
BookQuoters is a community of passionate readers who enjoy sharing the most meaningful, memorable and interesting quotes from great books. As the world communicates more and more via texts, memes and sound bytes, short but profound quotes from books have become more relevant and important. For some of us a quote becomes a mantra, a goal or a philosophy by which we live. For all of us, quotes are a great way to remember a book and to carry with us the author’s best ideas.
We thoughtfully gather quotes from our favorite books, both classic and current, and choose the ones that are most thought-provoking. Each quote represents a book that is interesting, well written and has potential to enhance the reader’s life. We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.
Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
