Leibniz' Monadology, one of the most important pieces of the Leibniz corpus, is at once one of the great classics of modern philosophy & one of its most puzzling productions. Because the essay is written in so compactly condensed a fashion, for almost three centuries it has baffled & beguiled those who read it for the first time. Nicholas Rescher accompanies the text of the Monadology section-by-section with relevant excerpts from some of Leibniz' widely scattered discussions of the matters at issue. The result serves a dual purpose of providing a commentary of the Monadology by Leibniz himself, while at the same time supplying an exposition of his philosophy using the Monadology as an outline. The book contains all the materials that even the most careful study of this text could require: a detailed overview of the philosophical background of the work & of its bibliographic ramifications; a presentation of the original French text together with a new, closely faithful English translation; a selection of other relevant Leibniz texts; & a detailed commentary. Rescher also provides a survey of Leibniz' use of analogies & three separate indices of key terms & expressions, Leibniz' French terminology, & citations. Rescher's edition of the Monadology presents Leibniz' ideas faithfully, accurately & accessibly, making it especially valuable to scholars & students alike.

    That long-out-of-print book--which discussed the most interesting reports of more than 1,000 apparently reliable witnessess--has become an underground classic and is now being reissued.

    In this collection of landmark mathematical works, editor Stephen Hawking has assembled the greatest feats humans have ever accomplished using just numbers and their brains.

    Rucker acquaints us with Godel's rotating universe, in which it is theoretically possible to travel into the past, and explains an interpretation of quantum mechanics in which billions of parallel worlds are produced every microsecond. It is in the realm of infinity, he maintains, that mathematics, science, and logic merge with the fantastic. By closely examining the paradoxes that arise from this merging, we can learn a great deal about the human mind, its powers, and its limitations.Using cartoons, puzzles, and quotations to enliven his text, Rucker guides us through such topics as the paradoxes of set theory, the possibilities of physical infinities, and the results of Godel's incompleteness theorems. His personal encounters with Godel the mathematician and philosopher provide a rare glimpse at genius and reveal what very few mathematicians have dared to admit: the transcendent implications of Platonic realism.

    Fearlessly pondering life’s end, Holloway examines how doubts too often paralyze people. He explains, “A sentence is not finished till it has a full stop, and every life needs a dying to complete it … Our brief finitude is but a beautiful spark in the vast darkness of space. So we should live the fleeting day with passion and, when the night comes, depart from it with grace.” Written in the context of organized religion’s structural difficulties, Looking in the Distance is a highly personal and meditative work that helps us better understand the myriad ways in which the human search for wholeness and healing can be approached. Accessible, funny, inquisitive and ever hopeful, it will inspire all who read it.

    

    And this language is mathematics." In The Language of Mathematics, award-winning author Keith Devlin reveals the vital role mathematics plays in our eternal quest to understand who we are and the world we live in. More than just the study of numbers, mathematics provides us with the eyes to recognize and describe the hidden patterns of life—patterns that exist in the physical, biological, and social worlds without, and the realm of ideas and thoughts within.Taking the reader on a wondrous journey through the invisible universe that surrounds us—a universe made visible by mathematics—Devlin shows us what keeps a jumbo jet in the air, explains how we can see and hear a football game on TV, allows us to predict the weather, the behavior of the stock market, and the outcome of elections. Microwave ovens, telephone cables, children's toys, pacemakers, automobiles, and computers—all operate on mathematical principles. Far from a dry and esoteric subject, mathematics is a rich and living part of our culture. An exploration of an often woefully misunderstood subject, The Language of Mathematics celebrates the simplicity, the precision, the purity, and the elegance of mathematics.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    . . and may still be here today.We are not alone.And we never have been.For years we've been taught that human progress has been a long, slow climb from the primordial ooze to hunter-gathers to empires. But that's only part of the story says Jim Marrs. The author who has investigated the recent financial crisis, the JFK assassination, secret societies, the national socialist takeover of America, and other events now takes on his biggest subject-the history of mankind-offering mind-blowing information that will radically alter the way we think about the world and our place in it.Our Occulted History overturns conventional knowledge and beliefs, presenting compelling evidence that the earth once hosted prehistoric civilizations using technologies that very well may have surpassed our own-societies that may have originated with non-humans. Sounds unbelievable? So was the concept that the earth was round-and that it revolved around the sun-to our predecessors just a few hundred years ago.Marrs sifts through the historical, scientific, and cultural record, showing how numerous ancient texts and tablets tell of visitors from the stars colonizing the Earth. From the flying vimanas of the Hindu Vedic literature and the flying shields reported by the Romans to the mysterious airships of the 1800s and the UFOs of today, he argues that someone other than us is still present on this planet. But are these visitors simply observers-or do they play a much more active and controlling role? Jim Marrs raises this shocking question and more in the provocative and persuasive Our Occulted History.The truth is out there . . . and in here.

    Though most people know of him only for the famous Pythagorean Theorem (a2 +b2=c2), in fact the pillars of our scientific tradition—belief that the universe is rational, that there is unity to all things, and that numbers and mathematics are a powerful guide to truth about nature and the cosmos—hark back to the convictions of this legendary sixth-century B.C. scholar.Born around 570 B.C. on the cultured Aegean island of Samos, Pythagoras (according to ancient tales) studied with the sage Thales nearby at Miletus, and with priests and scribes in Egypt and Babylon. Eventually he founded his own school at Croton in southern Italy, where he and his followers began to unravel the surprising deep truths concealed behind such ordinary tasks as tuning a lyre. While considering why some string lengths produced beautiful sounds and others discordant ones, they uncovered the ratios of musical harmony, and recognized that hidden behind the confusion and complexity of nature are patterns and orderly relationships. They had surprised the Creator at his drafting board and had glimpsed the mind of God! Some of them later would also find something darker in numbers and nature: irrationality, a revelation so unsettling and subversive that it may have contributed to the destruction of their brotherhood.Praised for her ability to illuminate complex subjects, Kitty Ferguson brilliantly evokes the archaic world of Pythagoras, showing how ideas spread in antiquity, chronicling the influence he and his followers have had on so many extraordinary people in the history of Western thought and science, and bringing a poignant human saga to readers who are daily reminded that harmony and chaos can and do coexist.

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    Ranging from the depths of the ocean to the most arid corners of the land, Caspar Henderson captures the beauty and bizzareness of the many living forms we thought we knew and some we could never have contemplated, inviting us to better imagine the precarious world we inhabit.A witty, vivid blend of cutting edge natural history and meditative reflections, The Book of Barely Imagined Beings is infectious and celebratory about the sheer ingenuity and variety of life.

    Every aspect of esoteric doctrine and practice is exhaustively dealt with and every authority cited.

    It is universally recognized as the standard English version of Aristotle. This revised edition contains the substance of the original translation, slightly emended in light of recent scholarship; three of the original versions have been replaced by new translations; and a new and enlarged selection of Fragments has been added. The aim of the translation remains the same: to make the surviving works of Aristotle readily accessible to English speaking readers.
