“My earliest memories are of CP4 — that's a Kähler manifold that looks locally like a vector space with four complex directions, though the global topology's quite different. But I didn't really grow up there; I was moved around a lot when I was young, to keep my perceptions flexible. I only used to spend time in anything remotely like this" — he motioned at the surrounding more-or-less-Euclidean space — for certain special kinds of physics problems. And even most Newtonian mechanics is easier to grasp in a symplectic manifold; having a separate visible coordinate for the position and momentum of every degree of freedom makes things much clearer than when you cram everything together in a single three-dimensional space.”
― Greg Egan, quote from Schild's Ladder
“You’ll never stop changing, but that doesn’t
mean you have to drift in the wind. Every day, you can take
the person you’ve been, and the new things you’ve witnessed,
and make your own, honest choice as to who you should become.
“Whatever happens, you can always be true to yourself. But
don’t expect to end up with the same inner compass as anyone
else. Not unless they started beside you, and climbed beside
you every step of the way.”
― Greg Egan, quote from Schild's Ladder
“It was a rigorous result in information theory that once you could learn in a sufficiently flexible manner – something humanity had achieved in the Bronze Age – the only limits you faced were speed and storage; any other structural changes were just a matter of style.”
― Greg Egan, quote from Schild's Ladder
“There's nothing worse than a label to cement people's loyalties.”
― Greg Egan, quote from Schild's Ladder
“You don't take a traveler for a partner if you hope that the world will always stay the same. You do it because you can't quite break away, yourself, but you can't live without the promise of change hanging over you every day.
That's what the border means, for a lot of people. The promise of change they'd never be able to make any other way.”
― Greg Egan, quote from Schild's Ladder
“That was the hazard she’d face every day, here: not just the risk that she’d give in to temptation, but the risk that all the principles she’d chosen to define herself would come to seem like nothing but masochistic nonsense.”

“It wasn’t really a loud-mouthed, hyperactive little pig-tailed blonde that made Carl cringe. It was what I represented. While his upbringing was battered humiliation, I was spoiled, doted on, and spoon-fed by the world. I don’t think he was even aware of his intentions to reduce that child to his own state of self-loathing, but he was truly brilliant at it.”
― Maggie Georgiana Young, quote from Just Another Number
“These axons can shuttle information around so quickly because they’re fatter than normal axons, and because they’re sheathed in a fatty substance called myelin. Myelin acts like rubber insulation on wires and prevents the signal from petering out: in whales, giraffes, and other stretched creatures, a sheathed neuron can send a signal multiple yards with little loss of fidelity. (In contrast, diseases that fray myelin, like multiple sclerosis, destroy communication between different nodes in the brain.) In sum, you can think about the gray matter as a patchwork of chips that analyze different types of information, and about the white matter as cables that transmit information between those chips. (And before we go further, I should point out that “gray” and “white” are misnomers. Gray matter looks pinkish-tan inside a living skull, while white matter, which makes up the bulk of the brain, looks pale pink. The white and gray colors appear only after you soak the brain in preservatives. Preservatives also harden the brain, which is normally tapioca-soft. This explains why the brain you might have dissected in biology class way back when didn’t disintegrate between your fingers.)”

“You are my greatest virtue and my deepest vice.”
― Sylvain Reynard, quote from The Raven
“I guess I always thought,” Ivy said softly, “that if I was strong enough, if I was formidable enough, if I was successful enough—I could be enough. For you. I thought that if I became this person who could take on the world, then I could take care of you.” She shook her head—at her past self, maybe, or to snap herself out of it. “When I came to Montana that summer, Tess, I thought I was ready. I really did. I was going to give you everything. But Gramps called me out, and he was right, Tessie. I wasn’t doing it for you. You were thriving. You were happy. And I . . .” The words got caught in her throat, but she forced them out. “I was your sister. I was never going to be strong enough or successful enough. There was never going to be a right time to tell you. You were happy. And you deserved to be happy.”
― Jennifer Lynn Barnes, quote from The Fixer
“More often than you might think, it takes getting to your lowest point before you realize you need to make a change.”

TeethBookQuoters 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.
