Quotes from The Principia: Mathematical Principles of Natural Philosophy

“This most beautiful system [The Universe] could only proceed from the dominion of an intelligent and powerful Being.”
― Isaac Newton, quote from The Principia: Mathematical Principles of Natural Philosophy

“Kepler's laws, although not rigidly true, are sufficiently near to the truth to have led to the discovery of the law of attraction of the bodies of the solar system. The deviation from complete accuracy is due to the facts, that the planets are not of inappreciable mass, that, in consequence, they disturb each other's orbits about the Sun, and, by their action on the Sun itself, cause the periodic time of each to be shorter than if the Sun were a fixed body, in the subduplicate ratio of the mass of the Sun to the sum of the masses of the Sun and Planet; these errors are appreciable although very small, since the mass of the largest of the planets, Jupiter, is less than 1/1000th of the Sun's mass.”
― Isaac Newton, quote from The Principia: Mathematical Principles of Natural Philosophy

“Resistance is usually ascribed to bodies at rest, and impulse to those in motion; but motion and rest, as commonly conceived, are only relatively distinguished; nor are those bodies always truly at rest, which commonly are taken to be so.”
― Isaac Newton, quote from The Principia: Mathematical Principles of Natural Philosophy

“This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being. And if the fixed stars are the centers of other like systems, these, being formed by the like wise counsel, must be all subject to the dominion of One.”
― Isaac Newton, quote from The Principia: Mathematical Principles of Natural Philosophy

“the one as much as it advances that of the other. If a body impinge upon another, and by its force change the motion of the other, that body also (because of the equality of the mutual pressure) will undergo an equal change, in its own motion, towards the contrary part.”
― Isaac Newton, quote from The Principia: Mathematical Principles of Natural Philosophy

“Hypotheses non fingo (Latin for "I feign no hypotheses", "I frame no hypotheses", or "I contrive no hypotheses")”
― Isaac Newton, quote from The Principia: Mathematical Principles of Natural Philosophy

“What do you mean you live someplace where there aren’t any humans? (Danger)
In a realm far away from here. (Alexion)
Is that like in star Wars? A long time ago, in a galaxy far, far away? Want to tell me where your Tatooine is located? Is it anywhere in this universe? Near Toledo maybe? The one in Ohio or Spain? I’m not picky. Can I MapQuest it? (Danger)”

“I call it the Pretty Paradox. Pretty girls always want guys who treat them, and most everyone else, like complete shit. It is perhaps one of the most baffling phenomena of history."---Cullen”

“You're the one who has to live with your choice," she says. "Everyone else will get over it, move on, no matter what you decide. But you never will.”
― Veronica Roth, quote from The Transfer

“Oči má šedé. Vlasy má rozcuchané a mokré. Prsty má jako buřtíky. Nehty má pokousané a polámané. Zuby má křivé, rozeklané. Má prázdný pohled, a když jste jí poblíž, vzbuzuje ve vás pocit nepřítomnosti, který se nedá slovy vyjádřit. Jejím znakem je prsten s háčkem. Jednoho dne se vám ten háček zadře do srdce. Popsat ji znamená vyjádřit, co je a proč je: přijde, když naděje pomine. Je v tisících čekáren a prázdných ulicích, v budovách ze šedého betonu a v bezejmenných hotelech. Je na druhé straně každého zrcadla. když tě oči, které se na tebe dívají, znají až moc dobře. Stojí a čeká a v jejím postoji ti už bolest neříká, abys žil, a v její přítomnosti je radost nepředstavitelná.”
― Neil Gaiman, quote from The Sandman: Endless Nights

“She sang, as requested. There was much about love in the ballad: faithful love that refused to abandon its object; love that disaster could not shake; love that, in calamity, waxed fonder, in poverty clung closer. The words were set to a fine old air -- in themselves they were simple and sweet: perhaps, when read, they wanted force; when well sung, they wanted nothing. Shirley sang them well: she breathed into the feeling, softness, she poured round the passion, force: her voice was fine that evening; its expression dramatic: she impressed all, and charmed one.

On leaving the instrument, she went to the fire, and sat down on a seat -- semi-stool, semi-cushion: the ladies were round her -- none of them spoke. The Misses Sympson and the Misses Nunnely looked upon her, as quiet poultry might look on an egret, an ibis, or any other strange fowl. What made her sing so? They never sang so. Was it proper to sing with such expression, with such originality -- so unlike a school girl? Decidedly not: it was strange, it was unusual. What was strange must be wrong; what was unusual must be improper. Shirley was judged.”
― Charlotte Brontë, quote from Shirley

About BookQuoters

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.
