“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.”

“I have no beliefs,” said her mother. “Only hopes.”
― Caroline B. Cooney, quote from The Face on the Milk Carton
“Our bones only ache while the flesh is on them. Stretch it thin as the temple flesh of an ailing woman and still it serves to ache the bone and to move the bone about; and in like manner the night is a skin pulled over the head of day that the day may be in a torment. We will find no comfort until the night melts away; until the fury of the night rots out its fire.”
― Djuna Barnes, quote from Nightwood
“Me? I had no dreams. No longings. Dreams only set you up for disappointment. Plus, you had to have a life to have dreams of a better life.”
― Julie Anne Peters, quote from Luna
“I am beginning to understand the true difference between youth and age. Young people have time to make plans and think of new ideas. Older people need their whole energy to keep up with what’s already been set in motion.”
― Michael Cunningham, quote from A Home at the End of the World
“If we are not graced with an instinctive knowledge of how to make our technologized world a safe and balanced ecosystem, we must figure out how to do it. We need more scientific research and more technological restraint. It is probably too much to hope that some great Ecosystem Keeper in the sky will reach down and put right our environmental abuses. It is up to us. It should not be impossibly difficult. Birds—whose intelligence we tend to malign—know not to foul the nest. Shrimps with brains the size of lint particles know it. Algae know it. One-celled microorganisms know it. It is time for us to know it too.”

All Our YesterdaysBookQuoters 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.
