“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 is the foundation of that interest all men feel in Greek history, letters, art, and poetry, in all its periods, from the Heroic or Homeric age down to the domestic life of the Athenians and Spartans, four or five centuries later? What but this, that every man passes personally through a Grecian period.”

“We make the beet salad by steaming the beets until soft, about thirty minutes, plunging into cold water, and removing the skins. After cutting the beets into small cubes, we toss them with a vinaigrette of orange juice, vinegar, olive oil, and shallots, adding crumbles of goat cheese and green onion, for color and taste and crunch, at the end.”
― Christina Baker Kline, quote from The Way Life Should Be

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.
