“Geometry is 'number in space', music is 'number in time'.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“In a seven-tone scale the eighth note is the octave, twice the pitch of the first note, and so signals the movement to a new level. This may be why, in religious symbolism, the eighth step is often associated with spiritual evolution or salvation.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“Islamic patterns speak of infinity and the omnipresent center.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“Ludwig Schlafi (1814-1895) proved that there are six regular four-dimensional polytopes (generalisations of polyhedra): the 5-cell made of tetrahedra, the 8-cell or tesseract made of cubes, the 16-cell made of tetrahedra, the 24-cell made of octahedra, the 120-cell made of dodecahedra, and the 600-cell made of tetrahedra.”

“Many familiar objects from cassettes to credit cards and Georgian front doors are Phi (1.618...) rectangles.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“When one circle is drawn over another like this so that they pass through each others' centers, then an important almond shape, the vesica piscis, literally 'fish's bladder' is formed. It is one of the first things that circles can do. Christ is often depicted inside a vesica.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“The dodecagon is also made from six squares and six equilateral triangles fitted around a hexagon”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“Twelve is the number which fits around one in three dimensions in the same way that six fits around one in two dimensions. The New Testament is a story of a teacher surrounded by twelve disciples.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“Ten is formed from two pentagons and ten life-invoking pentagons sit perfectly arpund a decagon, and DNA, appropriately as the key to the reproduction of life, has ten steps for each turn of its double helix, so appears in cross-section as a tenfold rosette.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“Eleven is important as the first number that allows us to begin to comprehend the measure of a circle. This is because, for practical purposes, a circle measuring seven across will measure eleven halfway around.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“Venus draws a fivefold pattern around Earth every eight years allowing us to draw an amazing diagram. In those eight years there are almost exactly 99 full moons, nine elevens, the number of names or reflections of Allah in Islam. Jupiter draws a beautiful elevenfold pattern around Earth.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“The ancient Maya were superb stargazers. Their calendar synchronized not just the Sun and Moon, byt also Venus and Mars. They worked out that 81 (or 3X3X3X3) full moons occur exactly every 2,392 (or 8X13X23) days, an astonishingly accurate gearing.”
― quote from Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology
“The ancients were obsessed with measures, and the number eleven is central in their metrological scheme. Shown opposite is the extraordinary fact that the size of the Moon relates to the size of the Earth as does three to eleven. What this means is that if we draw down the Moon to the Earth, as shown, then a heavenly circle through the moon will have a circumference equal to the perimeter of a square around the Earth. This is called 'squaring the circle'. Quite how the old druids worked this out we may never know, but they clearly did, for the Moon and the Earth are best measured in miles, as shown. A double rainbow also magically squares the circle.”

“Neither you nor I speak English, but there are some things that can be said only in English.”
― Aravind Adiga, quote from The White Tiger
“Women have served all these centuries as looking glasses possessing the magic and delicious power of reflecting the figure of man at twice its natural size.”
― Virginia Woolf, quote from A Room of One's Own
“This private estate was far enough away from the explosion so that its bamboos, pines, laurel, and maples were still alive, and the green place invited refugees—partly because they believed that if the Americans came back, they would bomb only buildings; partly because the foliage seemed a center of coolness and life, and the estate’s exquisitely precise rock gardens, with their quiet pools and arching bridges, were very Japanese, normal, secure; and also partly (according to some who were there) because of an irresistible, atavistic urge to hide under leaves.”
― John Hersey, quote from Hiroshima
“She would have to be a saint because that was the occupation that included everything you could know; and yet she knew she would never be a saint.... but she thought she could be a martyr if they killed her quick.”
― Flannery O'Connor, quote from A Good Man is Hard to Find and Other Stories
“He knew that beauty faded quickly when embodied by selfishness,”
― Francine Rivers, quote from A Voice in the Wind

TreasonBookQuoters 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.
