In the 1600s they issued a set of manifestos calling for an enlightened revolution that would reshape society into a more democratic ideal. Even the American Founding Fathers were influenced by these manifestos.Writing as Magus Incognito, William Walker Atkinson reintroduces a new generation of readers to the Rosicrucian ideals, as well as to a myriad of connections between occult concepts as varied as alchemy, reincarnation, the astral plane, auras, Eastern and Western mysticism, and the "evolution of mankind" among seven esoteric versions of planets in our solar system.There are more than two dozen organizations of Rosicrucians, with local groups in nearly every state--more than 100 in all--and half a million or more followers. Interest continues to be high in this group.

    Silver translates our most important, and often most obscure, scientific developments into a vernacular that is not only accessible and illuminating but also enjoyable. Silver makes his comprehensive case with much clarity and insight; his book aptly locates science as the apex of human reason, and reason as our best path to the truth. For all readers curious about--or else perhaps intimidated by--what Silver calls the scientific campaign up to now in his Preface, The Ascent of Science will be fresh, vivid, and fascinating reading.

     People everywhere have heard of Waldorf schools, Biodynamic farming, Camphill Villages, and other innovations of the Austrian philosopher Rudolf Steiner (1861-1925). Indeed, Steiner-as an architect, artist, teacher, and agriculturalist-ranks among the most creative and prolific figures of the early twentieth century, pioneering work in alternative education, holistic health, and environmental research. While his accomplishments are felt all over the world, few people understand this unusual figure. Steiner's own writings and lectures fill several bookcases, intimidating those who would like to know more. Works on Steiner are often dense and "insider" in tone, further deterring the curious. No popular biography, written by a sympathetic but critical outsider, has been available. Gary Lachman's Rudolf Steiner provides this missing introduction. Along with telling Steiner's story and placing Steiner in his historical context, Lachman's book presents Steiner's key ideas in a readable, accessible manner. In particular, Lachman considers the spread of Steiner's most popular projects, which include Waldorf schools-one of the leading forms of alternative education-and Biodynamic farming-a popular precursor to organic farming. He also traces Steiner's beginnings as a young intellectual in the ferment of fin de si?cle culture, to his rise as a thought leader within the influential occult movement of Theosophy, to the founding of his own metaphysical teaching called Anthroposophy. Finally, the book illustrates how Steiner's methods are put into practice today, and relates Steiner's insights into cosmology to the work of current thinkers. Rudolf Steiner is a full-bodied portrait of one of the most original philosophical and spiritual luminaries of the last two centuries, and gives those interested in the history of ideas the opportunity to discover one of the most underappreciated figures of the twentieth century.

    Harmonograph is an introduction to the evolution of simple harmonic theory, from the discoveries of Pythagoras to diatonic tuning and equal temperament. Beautiful drawings show the octave as triangle, the fifth as pentagram; diagrams show the principles of harmonics, overtones, and the monochord. Anthony Ashton examines the phenomenon of resonance in Chladni patterns, describes how to build a harmonograph of your own, and provides tables of world tuning systems. This inspiring book will appeal to musicians, mathematicians, designers, and artists alike.

    In this simple pattern beginning with two ones, each succeeding number is the sum of the two numbers immediately preceding it (1, 1, 2, 3, 5, 8, 13, 21, ad infinitum). Far from being just a curiosity, this sequence recurs in structures found throughout nature - from the arrangement of whorls on a pinecone to the branches of certain plant stems. All of which is astounding evidence for the deep mathematical basis of the natural world. With admirable clarity, two veteran math educators take us on a fascinating tour of the many ramifications of the Fibonacci numbers. They begin with a brief history of a distinguished Italian discoverer, who, among other accomplishments, was responsible for popularizing the use of Arabic numerals in the West. Turning to botany, the authors demonstrate, through illustrative diagrams, the unbelievable connections between Fibonacci numbers and natural forms (pineapples, sunflowers, and daisies are just a few examples). In art, architecture, the stock market, and other areas of society and culture, they point out numerous examples of the Fibonacci sequence as well as its derivative, the "golden ratio." And of course in mathematics, as the authors amply demonstrate, there are almost boundless applications in probability, number theory, geometry, algebra, and Pascal's triangle, to name a few.Accessible and appealing to even the most math-phobic individual, this fun and enlightening book allows the reader to appreciate the elegance of mathematics and its amazing applications in both natural and cultural settings.

    Pure mathematics, the area of Bourbaki's work, seems on the surface to be an abstract field of human study with no direct connection with the real world. In reality, however, it is closely intertwined with the general culture that surrounds it. Major developments in mathematics have often followed important trends in popular culture; developments in mathematics have acted as harbingers of change in the surrounding human culture. The seeds of change, the beginnings of the revolution that swept the Western world in the early decades of the twentieth century — both in mathematics and in other areas — were sown late in the previous century. This is the story both of Bourbaki and the world that created him in that time. It is the story of an elaborate intellectual joke — because Bourbaki, one of the foremost mathematicians of his day — never existed.

    Tender and joyous, it is a celebration of art's power to transform the darkest of human experience and give voice to the grandest of human hopes.

    C. Escher and composer Johann Sebastian Bach, discussing common themes in their work and lives. At a deeper level, the book is a detailed and subtle exposition of concepts fundamental to mathematics, symmetry, and intelligence. Through illustration and analysis, the book discusses how self-reference and formal rules allow systems to acquire meaning despite being made of "meaningless" elements. It also discusses what it means to communicate, how knowledge can be represented and stored, the methods and limitations of symbolic representation, and even the fundamental notion of "meaning" itself. In response to confusion over the book's theme, Hofstadter has emphasized that GEB is not about mathematics, art, and music but rather about how cognition and thinking emerge from well-hidden neurological mechanisms.

    Stimulating, illuminating, and always surprising, The Big Questions challenges readers to re-evaluate their most fundamental beliefs and reveals the relationship between the loftiest philosophical quests and our everyday lives.

    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.

    Exploring issues that range from faith to prayer to evil to immortality, and far beyond, Garnder challenges the discerning reader with fundamental questions of classical philosophy and life's greater meanings.Recalling such philosophers was Wittgenstein and Arendt, The Whys of Philosophical Scrivener embodies Martin Garner's unceasing interest and joy in the impenetrable mysteries of life.

    Beautifully illustrated with old engravings as well as contemporary imagery, Sacred Number introduces basic counting systems; significant numbers from major religious texts; the importance of astronomy, geometry, and music to number quality; how numbers affect architecture. Lundy explains why the ideas of Pythagoras still resonate, and she profiles each number from one to ten to show its distinct qualities: why, for example, the golden section is associated with five, and seven with the Virgin Mary.
