Few episodes in the development of scientific theory show so clearly how the solution to a highly technical problem can alter our basic thought processes and attitudes. Understanding the processes which underlay the Revolution gives us a perspective, in this scientific age, from which to evaluate our own beliefs more intelligently. With a constant keen awareness of the inseparable mixture of its technical, philosophical, and humanistic elements, Thomas S. Kuhn displays the full scope of the Copernican Revolution as simultaneously an episode in the internal development of astronomy, a critical turning point in the evolution of scientific thought, and a crisis in Western man's concept of his relation to the universe and to God.The book begins with a description of the first scientific cosmology developed by the Greeks. Mr. Kuhn thus prepares the way for a continuing analysis of the relation between theory and observation and belief. He describes the many functions--astronomical, scientific, and nonscientific--of the Greek concept of the universe, concentrating especially on the religious implications. He then treats the intellectual, social, and economic developments which nurtured Copernicus' break with traditional astronomy. Although many of these developments, including scholastic criticism of Aristotle's theory of motion and the Renaissance revival of Neoplatonism, lie entirely outside of astronomy, they increased the flexibility of the astronomer's imagination. That new flexibility is apparent in the work of Copernicus, whose De Revolutionibus Orbium Coelestium (On the Revolutions of the Heavenly Spheres) is discussed in detail both for its own significance and as a representative scientific innovation.With a final analysis of Copernicus' life work--its reception and its contribution to a new scientific concept of the universe--Mr. Kuhn illuminates both the researches that finally made the heliocentric arrangement work, and the achievements in physics and metaphysics that made the planetary earth an integral part of Newtonian science. These are the developments that once again provided man with a coherent and self-consistent conception of the universe and of his own place in it.This is a book for any reader interested in the evolution of ideas and, in particular, in the curious interplay of hypothesis and experiment which is the essence of modern science. Says James Bryant Conant in his Foreword: "Professor Kuhn's handling of the subject merits attention, for...he points the way to the road which must be followed if science is to be assimilated into the culture of our times."

    It developed into one of the most powerful corporations in the medieval world which lasted for nearly two centuries until its suppression in 1312. Despite the loss of its central archive in the sixteenth century, the Order left many records of its existence as the spearhead of crusading activity in Palestine and Syria, as the administrator of a great network of preceptories and lands in the Latin west, and as a banker and ship-owner. Because of the dramatic nature of its abolition, it has retained its grip on the imagination and consequently there has developed an entirely fictional 'after-history' in which its secret presence has been evoked to explain mysteries which range from masonic conspiracy to the survival of the Turin Shroud. This book offers a concise and up-to-date introduction to the reality and the myth of this extraordinary institution.

    Here the trials and triumphs of the early Muslims as individuals are well-portrayed. Their various paths to Islam - sometimes direct, sometimes long and tortuous, their devotion to the noble Prophet, their endeavours in peace time and their exploits in war - all serve to cast them in a heroic mould. This is the first of two (formerly published as a series of three) books based on original Arabic sources and written in a style that is lively and often gripping. The lives of the Sahabah or Companions of the Prophet, may God bless him and grant him peace, is a rich storehouse of knowledge, guidance and inspiration. The men and women whose stories are told here helped to lay the foundations of a new world order, and it is only fitting that they should be more widely known.

    It is true that they pillaged, looted, and enslaved. But they also settled peacefully and traveled far from their homelands in swift and sturdy ships to explore. The Age of the Vikings tells the full story of this exciting period in history. Drawing on a wealth of written, visual, and archaeological evidence, Anders Winroth captures the innovation and pure daring of the Vikings without glossing over their destructive heritage. He not only explains the Viking attacks, but also looks at Viking endeavors in commerce, politics, discovery, and colonization, and reveals how Viking arts, literature, and religious thought evolved in ways unequaled in the rest of Europe. The Age of the Vikings sheds new light on the complex society, culture, and legacy of these legendary seafarers.

    He begins with a stunning account of the Battle of Lepanto in 1571, then turns to the main zones of conflict: Spain, from which the descendants of the Moors were eventually expelled; the Middle East, where Crusaders and Muslims clashed for years; and the Balkans, where distant memories spurred atrocities even into the twentieth century. Throughout, Wheatcroft delves beneath stereotypes, looking incisively at how images, ideas, language, and technology (from the printing press to the Internet), as well as politics, religion, and conquest, have allowed each side to demonize the other, revive old grievances, and fuel across centuries a seemingly unquenchable enmity. Finally, Wheatcroft tells how this fraught history led to our present maelstrom. We cannot, he argues, come to terms with today’s perplexing animosities without confronting this dark past.

    This source book traces, through contemporary writings, the calamitous impact of the Black Death in Europe, with a particular emphasis on its spread across England from 1348 to 1349. Rosemary Horrox surveys contemporary attempts to explain the plague, which was universally regarded as an expression of divine vengeance for the sins of humankind. Moralists all had their particular targets for criticism. However, this emphasis on divine chastisement did not preclude attempts to explain the plague in medical or scientific terms. Also, there was a widespread belief that human agencies had been involved, and such scapegoats as foreigners, the poor and Jews were all accused of poisoning wells. The final section of the book charts the social and psychological impact of the plague, and its effect on the late-medieval economy.

    Their armies threatened states as far flung as the Franks in Western Europe and the Tang Empire in China. The conquered territory was larger than the Roman Empire at its greatest expansion, and it was claimed for the Arabs in roughly half the time. How this collection of Arabian tribes was able to engulf so many empires, states, and armies in such a short period has perplexed historians for centuries. Most accounts of the Arab invasions have been based almost solely on the early Muslim sources, which were composed centuries later to illustrate the divinely chosen status of the Arabs. Robert Hoyland's groundbreaking new history assimilates not only the rich biographical information of the early Muslim sources but also the many non-Arabic sources, contemporaneous or near- contemporaneous with the conquests.In God's Path begins with a broad picture of the Late Antique world prior to the Prophet's arrival, a world dominated by two superpowers: Byzantium and Sasanian Persia. In between these empires, emerged a distinct Arabian identity, which helped forge the inhabitants of western Arabia into a formidable fighting force. The Arabs are the principal actors in this drama yet, as Hoyland shows, the peoples along the edges of Byzantium and Persia--the Khazars, Bulgars, Avars, and Turks--all played critical roles in the remaking of the old world order. The new faith propagated by Muhammad and his successors made it possible for many of the conquered peoples to join the Arabs in creating the first Islamic Empire. Well-paced, comprehensive, and eminently readable, In God's Path presents a sweeping narrative of a transformational period in world history.

    Yet it was, according to Professor Harl, "without a doubt the greatest state in Christendom through much of the Middle Ages," and well worth our attention as a way to widen our perspective on everything from the decline of imperial Rome to the rise of the Renaissance.In a series of 24 tellingly detailed lectures, you'll learn how the Greek-speaking empire of Byzantium, or East Rome, occupied a crucial place in both time and space that began with Constantine the Great and endured for more than a millennium - a crucible where peoples, cultures, and ideas met and melded to create a world at once Eastern and Western, Greek and Latin, classical and Christian. And you'll be dazzled by the achievements of Byzantium's emperors, patriarchs, priests, monks, artists, architects, scholars, soldiers, and officialsPreserving and extending the literary, intellectual, and aesthetic legacy of Classical and Hellenistic GreeceCarrying forward path-breaking Roman accomplishments in law, politics, engineering, architecture, urban design, and military affairsDeepening Christian thought while spreading the faith to Russia and the rest of what would become the Orthodox worldDeveloping Christian monastic institutionsShielding a comparatively weak and politically fragmented western Europe from the full force of eastern nomadic and Islamic invasionsFusing classical, Christian, and eastern influencesHelping to shape the course of the Humanist revival and the Renaissance

    In his gripping and controversial new work, New York Times bestselling author Steven Pinker shows that despite the ceaseless news about war, crime, and terrorism, violence has actually been in decline over long stretches of history. Exploding myths about humankind's inherent violence and the curse of modernity, this ambitious book continues Pinker's exploration of the essence of human nature, mixing psychology and history to provide a remarkable picture of an increasingly enlightened world.

    The emergence of factories, railroads, and gunboats propelled the West’s rise to power in the nineteenth century, and the development of computers and nuclear weapons in the twentieth century secured its global supremacy. Now, at the beginning of the twenty-first century, many worry that the emerging economic power of China and India spells the end of the West as a superpower. In order to understand this possibility, we need to look back in time. Why has the West dominated the globe for the past two hundred years, and will its power last?Describing the patterns of human history, the archaeologist and historian Ian Morris offers surprising new answers to both questions. It is not, he reveals, differences of race or culture, or even the strivings of great individuals, that explain Western dominance. It is the effects of geography on the everyday efforts of ordinary people as they deal with crises of resources, disease, migration, and climate. As geography and human ingenuity continue to interact, the world will change in astonishing ways, transforming Western rule in the process.Deeply researched and brilliantly argued, Why the West Rules—for Now spans fifty thousand years of history and offers fresh insights on nearly every page. The book brings together the latest findings across disciplines—from ancient history to neuroscience—not only to explain why the West came to rule the world but also to predict what the future will bring in the next hundred years.

    With sharp analytic insight, Peter Heather explores the dynamics of migration and social and economic interaction that changed two vastly different worlds—the undeveloped barbarian world and the sophisticated Roman Empire—into remarkably similar societies and states. The book's vivid narrative begins at the time of Christ, when the Mediterranean circle, newly united under the Romans, hosted a politically sophisticated, economically advanced, and culturally developed civilization—one with philosophy, banking, professional armies, literature, stunning architecture, even garbage collection. The rest of Europe, meanwhile, was home to subsistence farmers living in small groups, dominated largely by Germanic speakers. Although having some iron tools and weapons, these mostly illiterate peoples worked mainly in wood and never built in stone. The farther east one went, the simpler it became: fewer iron tools and ever less productive economies. And yet ten centuries later, from the Atlantic to the Urals, the European world had turned. Slavic speakers had largely superseded Germanic speakers in central and Eastern Europe, literacy was growing, Christianity had spread, and most fundamentally, Mediterranean supremacy was broken. The emergence of larger and stronger states in the north and east had, by the year 1000, brought patterns of human organization into much greater homogeneity across the continent. Barbarian Europe was barbarian no longer. Bringing the whole of first millennium European history together for the first time, and challenging current arguments that migration played but a tiny role in this unfolding narrative, Empires and Barbarians views the destruction of the ancient world order in the light of modern migration and globalization patterns. The result is a compelling, nuanced, and integrated view of how the foundations of modern Europe were laid.

    Its success "might have established communal property, a far wider democracy in political and legal institutions, might have disestablished the state church and rejected the protestant ethic." In The World Turned Upside Down, Christopher Hill studies the beliefs of such radical groups as the Diggers, the Ranters, the Levellers and others, and the social and emotional impulses that gave rise to them. The relations between rich and poor classes, the part played by wandering 'masterless men,' the outbursts of sexual freedom and deliberate blasphemy, the great imaginative creations of Milton and Bunyan - these and many other elements build up into a marvellously detailed and coherent portrait of this strange, sudden effusion of revolutionary beliefs. It is a portrait not of the bourgeois revolution that actually took place, but of the impulse towards a far more fundamental overturning of society."Incorporates some of Dr. Hill's most profound statements yet about the 17th-century revolution as a whole." -- The Economist

    This provocative book shows that Europe in the Middle Ages was as much a product of a process of conquest and colonization as it was later a colonizer.
