    David Christian, professor of history at San Diego State University, surveys the past at all possible scales, from conventional history, to the much larger scales of biology and geology, to the universal scales of cosmology.

    Take an adventurous trek to these wilds of South America and the great civilizations of the ancients. In 24 eye-opening lectures, you'll take an in-depth look at the emerging finds and archaeological knowledge of more than 12 seminal civilizations, giving you rich insight into the creative vision and monumental achievements of these wellsprings of human life. The ancient South Americans show us striking models of how societies can function and organize themselves. The technologies and social structures seen here were wholly invented, using no preexisting models, as these dynamic peoples struggled to tame their environment and carve out societies and empires. Recently unearthed marvels include elaborately prepared and adorned mummies that predate Egypt's by 2000 years; imposing palaces, solar observatories, and dramatically decorated pyramids; stunning art objects in gold, turquoise, lapis lazuli, and ceramic; and evidence of huge urban civilizations in the Amazon. In their amazing sophistication and scale, the sites reveal some of the most remarkable ancient artifacts found anywhere in the world. The breathtaking valleys, mountains, and deserts you will study in this course reveal wonders that rival anything we know of the ancient world. Travel with us to a lost and splendorous past - a fountainhead of civilization that speaks unforgettably of human striving, vision, and the indomitable will to endure.Listening Length: 11 hours and 54 minutes

    As traders and raiders, explorers and colonists, they reshaped the world between eastern North America and the Asian steppe. For a millennium, though, their history has largely been filtered through the writings of their victims. Based on the latest archaeological and textual evidence, Children of Ash and Elm tells the story of the Vikings on their own terms: their politics, their cosmology, their art and culture. From Björn Ironside, who led an expedition to sack Rome, to Gudrid Thorbjarnardóttir, the most travelled woman in the world, Price shows us the real Vikings, not the caricatures they have become in popular culture and history.

    Its eastern half, which would come to be known as the Byzantine Empire, would endure and often flourish for another eleven centuries. Though its capital would move to Constantinople, its citizens referred to themselves as Roman for the entire duration of the empire’s existence. Indeed, so did its neighbors, allies, and enemies: When the Turkish Sultan Mehmet II conquered Constantinople in 1453, he took the title Caesar of Rome, placing himself in a direct line that led back to Augustus.For far too many otherwise historically savvy people today, the story of the Byzantine civilization is something of a void. Yet for more than a millennium, Byzantium reigned as the glittering seat of Christian civilization. When Europe fell into the Dark Ages, Byzantium held fast against Muslim expansion, keeping Christianity alive. When literacy all but vanished in the West, Byzantium made primary education available to both sexes. Students debated the merits of Plato and Aristotle and commonly committed the entirety of Homer’s Iliad to memory. Streams of wealth flowed into Constantinople, making possible unprecedented wonders of art and architecture, from fabulous jeweled mosaics and other iconography to the great church known as the Hagia Sophia that was a vision of heaven on earth. The dome of the Great Palace stood nearly two hundred feet high and stretched over four acres, and the city’s population was more than twenty times that of London’s.From Constantine, who founded his eponymous city in the year 330, to Constantine XI, who valiantly fought the empire’s final battle more than a thousand years later, the emperors who ruled Byzantium enacted a saga of political intrigue and conquest as astonishing as anything in recorded history. Lost to the West is replete with stories of assassination, mass mutilation and execution, sexual scheming, ruthless grasping for power, and clashing armies that soaked battlefields with the blood of slain warriors numbering in the tens of thousands.Still, it was Byzantium that preserved for us today the great gifts of the classical world. Of the 55,000 ancient Greek texts in existence today, some 40,000 were transmitted to us by Byzantine scribes. And it was the Byzantine Empire that shielded Western Europe from invasion until it was ready to take its own place at the center of the world stage. Filled with unforgettable stories of emperors, generals, and religious patriarchs, as well as fascinating glimpses into the life of the ordinary citizen, Lost to the West reveals how much we owe to this empire that was the equal of any in its achievements, appetites, and enduring legacy.

    More than 2,500 years later, the issues they pondered continue to challenge, fascinate, and instruct us. Is reality stable and permanent or is it always changing? Are ethical values like justice and courage relative? Or are values "absolute"—simply and forever right and true? What is justice? What is happiness? How shall we best live our lives?An Introduction to Greek Philosophy beckons you to join this eternal discussion. For that is what this subject truly is: a conversation among thinkers that has continued through the centuries and remains accessible to us today. You find it constantly stimulating, sometimes controversial, and nearly always remarkably relevant.A Hunger for Reasons, not Myths or BeliefsProfessor David Roochnik has organized this series of 24 lectures as a "dialectical" approach (the word comes from the Greek dialegesthai: to converse). The philosophers are presented as if they were participating in a conversation. In this way, the course unfolds in a manner similar to the actual development of Greek philosophy.In this course, you study the development of Greek philosophy, meet its major thinkers, and explore the issues and ideas that concerned them. For example the first real philosophers were the Presocratics—literally, the philosophers who lived before Socrates. They included Thales of Miletus (585 B.C.E.–?), Anaximander (610–546), Anaximenes (approx. 550), Xenophanes (approx. 570) and Pythagoras (approx. 570–500).The Presocratics rejected myth and divine inspiration—such as had been embodied in the works of Homer and in Hesiod's creation story, the Theogony—as valid explanations of reality. Instead, they insisted that true understanding always requires a logos, a rational explanation (hence such English words as "psychology" and "biology").The Presocratics were concerned with issues such as identifying the arche or "Being": the thing that is the origin of all other things. They also introduced sophistic relativism, the notion that truth, goodness, and all other values were relative, depending entirely on the person or group that held them. This concept would become a major point of debate for the Greeks and for the ages.Are We Footnotes to Plato?The heroes of this course, and certainly of Greek philosophy, are Plato (429–347 B.C.E.) and his student, Aristotle (384–322 B.C.E.). Unlike the Presocratics, who wrote too little, Plato and Aristotle were prolific authors. Both argued against relativism and instead were staunch objectivists who believed that certain important values were absolutely and universally true. And both left a staggering mark on history.Alfred North Whitehead, the great 20th-century British philosopher, said, "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato." In the Middle Ages, Aristotle was held in such high esteem that he was simply known as "the philosopher."Among Plato's many contributions to philosophy is his ingenious device for the examination of ideas: his written dialogues. In them, Plato never uses his own voice. Instead, the dialogues take place among a changing cast of characters, and Socrates is the most notable among them. The effect is to invite us to take part in the conversation and, ultimately, to become philosophers.You study Plato's dialogues as well as his notion of the Forms. This was his response to relativism and proposed that every virtue and value has an absolute and perfect Form, which humans understand even before birth.Greek philosophy can be said to culminate with Aristotle, who wrote treatises on a breathtaking range of subjects. He is said to be the first to view knowledge as being divided into specific disciplines such as biology or astronomy. The university was later modeled on this approach. More than any other philosopher, Aristotle synthesized the views that preceded him.For Aristotle, one value was foremost and was contained in everything, from the tiniest organisms to the phenomena of fire to human beings: purpose. Everything has a purpose that can be recognized and objectively defined, and that gives meaning to life. You explore the details and rationale of Aristotle's teleological—or purposive—world-view, one of the most significant in history.An Invitation to ThinkIn this course, you not only learn about Greek philosophy but, to some extent, how to do it. Professor Roochnik emphasizes that Greek philosophy is ultimately not about facts or answers but about the give-and-take of ideas.By the end of these lectures, you will understand how Greek philosophy still heavily influences our view of life. We live today, Professor Roochnik maintains, at a time that is shaped by Presocratic, relativistic philosophy. Contemporary thinkers, and often the average person, have great difficulty finding objective truth or meaning in life.What have we lost in turning away from the world of Plato and Aristotle—a world where everything has a place and a purpose and life is saturated with value and meaning?On the other hand, what would we lose if we returned to that world?These are a few of the many questions that will give you ample food for thought. For the Greeks, that was the greatest feast of all.

    Robinson Crusoe. Harry Potter. What do these memorable characters have in common? Why do we turn to certain stories again and again? And what impact have they made on world history? These 24 eye-opening lectures give fresh insight into some of the greatest heroes in world literature, from warriors such as Beowulf and Odysseus to unexpected heroes such as Uncle Tom and Sancho Panza.Professor Shippey gives you an inside glimpse into the writer's process. Learn how authors "write into the gap" to flesh out-or, in some cases, reimagine altogether-old stories, making them new for new readerships with different values. By examining what makes these heroes such compelling characters, you'll see how they provide a window to better understand ourselves.From the beginnings of world literature through today's bestsellers, look at what makes characters successful-and how they reflect our changing cultural mores. For instance, after the horrors of global war in the 20th century, the world was waiting for a hero like Frodo Baggins, J.R.R. Tolkien's meek hobbit hero, someone called to duty rather than born strong and fearless.You'll also examine ways that great heroes have changed the course of history, defining nations and redefining our sense of self and our relationships. From the mythical journey of Aeneas to Jane Austen's country dances, you'll survey a wealth of memorable stories and consider why such heroes were necessary-and how they continue to influence our lives today.

    The issues Professor Dalton addresses in these lectures - and in Western political theory generally - fall into three sets of fundamental questions you'll get to unpack. The first set involves the essential characteristics of human nature and the good society. The second focuses on the intricate relationship between the individual and society. And the final set of questions involves theories about change.Through these lectures and their historical case studies, you'll be able to identify the fundamental questions and concerns that shape classical and modern political theory:Describe the influence of one's understanding of human nature upon one's vision of the good society.Compare and contrast the views of theorists regarding the purpose of the state, the relationship between politics and ethics, and the qualifications for exercising political power.Discuss views of leading political theorists regarding the meaning of freedom, the sources of legitimate political authority, and the obligations of individuals to the state or society, and more.

    But have you ever wondered how a religion that doesn't even have a god could have accomplished this?Now you have the opportunity to have your questions answered, as this series of 24 lectures by an award-winning teacher traces the history, principles, and evolution of a theology that is both familiar and foreign.You'll learn the astonishing story of Siddhartha Gautama - who was to become the Buddha, or "enlightened one" - the Indian prince who abandoned wife, son, and a privileged life to seek the meaning of life and death, and whose "awakening" and subsequent teachings have since impacted the world as few others have.And you'll learn what happened after his death, as his followers began to share his teachings about the "Four Noble Truths" and the "Path" to Enlightenment. You'll see how Buddhist beliefs underwent significant and even radical change, with different varieties of Buddhism having to take shape as those beliefs spread across India, Central Asia, China, Japan, and virtually every corner of the Western world, such as becoming more respectful of one's duties to family and ancestors in China or becoming reconciled with local deities in Japan.

    On a chilly November night in 1407, Louis of Orleans was murdered by a band of masked men. The crime stunned and paralyzed France since Louis had often ruled in place of his brother King Charles, who had gone mad. As panic seized Paris, an investigation began. In charge was the Provost of Paris, Guillaume de Tignonville, the city's chief law enforcement officer -- and one of history's first detectives. As de Tignonville began to investigate, he realized that his hunt for the truth was much more dangerous than he ever could have imagined. A rich portrait of a distant world, Blood Royal is a gripping story of conspiracy, crime and an increasingly desperate hunt for the truth. And in Guillaume de Tignonville, we have an unforgettable detective for the ages, a classic gumshoe for a cobblestoned era.

    They first came into existence as an idea, before they had a common ruler and before the country they lived in even had a name. They have lasted as a recognizable entity ever since, and their defining national institutions can be traced back to the earliest years of their history.The English have come a long way from those precarious days of invasion and conquest, with many spectacular changes of fortune. Their political, economic and cultural contacts have left traces for good and ill across the world. This book describes their history and its meanings from their beginnings in the monasteries of Northumbria and the wetlands of Wessex to the cosmopolitan energy of today's England. Robert Tombs draws out important threads running through the story, including participatory government, language, law, religion, the land and the sea, and ever-changing relations with other peoples. Not the least of these connections are the ways the English have understood their own history, have argued about it, forgotten it, and yet been shaped by it. These diverse and sometimes conflicting understandings are an inherent part of their identity. Rather to their surprise, as ties within the United Kingdom loosen, the English are suddenly beginning a new period in their long history. Especially at times of change, history can help us to think about the sort of people we are and wish to be. This book, the first single-volume work on this scale for more than half a century, and which incorporates a wealth of recent scholarship, presents a challenging modern account of this immense and continuing story, bringing out the strength and resilience of English government, the deep patterns of division, and yet also the persistent capacity to come together in the face of danger.
