Almost daily, researchers are recovering lost information that corrects our picture of what had been a misunderstood era. As a result, we know more than ever about the roles women played in medieval life.       What did it mean to be a heroine in the medieval world? As the four subjects of this course make clear, it meant shaping and changing that world. In the monasteries and churches where people prayed, the universities where they wrote and thought, and even on the political map of Europe itself, these women made differences perceived not only in our time, but in theirs. Women of Intellect, Words, and Passion        These lectures are an extraordinary opportunity to study great women of the past in their own words. Professor Wheeler bases her discussions on recently discovered or recovered written records they left behind, from Hildegard's prodigious scholarship to the personal letters of Heloise and detailed transcripts of Joan of Arc's trial.       With these documents as a basis, you will see Heloise (1101-1163) as a forerunner of Europe's new day. Her letters passionately overflow with the new knowledge of her day. With her star-crossed love, Abelard, she invented a new mode of philosophic thought.       Only now are scholars recovering the long, important second half of the story of Heloise as a woman of power after Abelard's death. Her letters show her to be well versed on such topics as Cicero, classical philosophy, Latin poetry, and rhetoric.       She saw the institution of marriage in her day as little more than a commercial transaction, and its duties burdensome, noisy, costly, and dirty. Her letters reveal her desire to be Abelard's "meretrix" (prostitute) rather than his "imperatrix" (empress). In her discussions on Heloise, Professor Wheeler also covers the long debate as to whether Abelard and Heloise's letters to one anotherthe first, first-person record of a love affair in human history are genuine or not.       Hildegard of Bingen, like Heloise a 12th-century abbess, is revealed as the last flowering of antique learning. She lived a dramatic life as a mystic, voluminous writer, and preacher. She was a personal advisor to Emperor Frederick Barbarossa, and her political involvement and passion as an advocate for clerical and imperial reform give her special interest in our day.       Only in the last generation have scholars rediscovered this amazing medieval intellect. Based on her letters, at least four popes and 10 archbishops corresponded with her, not to mention some 100 other individuals notable to history.Among her many writings, her Book of Simple Medicine was an impressive mini-encyclopedia on what we today would call the natural sciences.       But Hildegard is also known as the "holy hypochondriac," subject to disabling migraines. Were her visions delusions, a result of brainstorms caused by chemical imbalances? Women of Action and Legend        Eleanor of Aquitaine (1124-1204), Queen of France and then England, mother of at least 10 children, scandalized her contemporaries and has fascinated us ever since. She accompanied her husband, Louis VII, on the second Crusade, and her exploits are a reminder that women were crusaders not merely camp followers in numbers that rivaled those of men.       You will learnbased on as-yet-unpublished research by Professor Andrew Lewis that Eleanor was probably born in 1124, not 1122 as normally thought. As a physically hearty woman of courage, she provides a way for historians to explore the diverse roles that women played in enabling or resisting the Crusades. This is exciting work that will allow us to understand medieval women outside the context of home and family as agents of sometimes-radical change.       Eleanor's life is so amazing that it is easy to see why she has become the staple of legends. Among those you will consider are whether she passionately adored, then fought endlessly with, her second husband, Henry II of England (all too true); whether she poisoned Henry's mistress, Rosamund (no proof); and whether she held "courts of love" to encourage and engage in amatory liaisons (again, unproven).       Joan of Arc (1412-1431) was the illiterate French peasant girl whom Mark Twain described as the "youngest person of either sex to lead her nation's army before the age of 19." Known as La Pucelle " (the "maid" or "virgin"), she lacked any kind of military training, yet her military instincts seemed impeccable. Although she carried a sword in battle, she never used it to kill a man, and seems never to have become used to the sight of dead or dying men.Was this young woman who heard heavenly voices an incomprehensible quirk, or did she change the course of European and world history? Ironically, this debate is complicated by the detailed transcripts of her trials, which make her one of the best-documented figures of pre-modern times.       Trial records and her letters reveal her as someone who spoke with "compelling simplicity, quick wit, and piercing honesty." This girl spoke terribly well," said Albert d'Ourches. "I would really like to have had so fine a daughter."       Professor Wheeler dismisses as myth the notions that Joan was actually of noble birth, or that she never fully developed physically as a woman. These lectures reveal Joan as perhaps most memorable for what she was not: a queen, a mother, a beauty, or an intellectual. Instead, she was a woman of action, and the kind of person who is often an enigma to modern intellectuals: someone of profound religious faith.       Appreciating how these four heroines have been understood and misunderstood will help you understand how history passes judgment on both women and the Middle Ages. The contemporary research upon which this course is based can move us beyond how women "ought" to have been to better knowledge, however precarious, about how women were. 24 Lectures 1.

    What exactly happened, such that Jesus came to be considered God?To ask this question is to delve into a fascinating, multilayered historical puzzle - one that offers a richly illuminating look into the origins of the Western worldview and the theological underpinnings of our civilization. This fundamental historical question and its complex answer speak penetratingly to the spiritual impulses, concerns, and beliefs that have played a seminal role in our world, even as they reveal the foundation of history's most global religious movement, and fresh insights into the Western world's single most influential human being.Tackling all of these matters and more, Great Courses favorite Professor Ehrman returns with the unprecedented historical inquiry of How Jesus Became God. In 24 provocative lectures, Professor Ehrman takes you deep into the process by which the divinity of Jesus was first conceived by his followers, demonstrating how this conception was refined over time to become the core of the Christian theology. A distinguished scholar of Christianity and New York Times best-selling author, Professor Ehrman develops the inquiry with meticulous research and in-depth analysis of texts. In these lectures, Ehrman reveals that the theological understanding of Jesus as God came about through a complex series of factors and events, each of which must be understood in order to grasp this most extraordinary and historically pivotal story.In the enthralling inquiry of How Jesus Became God Professor Ehrman lays bare the diverse elements that combined to produce both an astonishing true-life story and one of history's most significant developments. Join a renowned biblical scholar in grappling with this pivot.

    You learn the points of view your teachers provide, the perspectives that books offer, and the conclusions you draw yourself based on the facts you were given. Hearing different angles on historical events gives you a more insightful, more accurate, and more rewarding understanding of events – especially when a new viewpoint challenges the story you thought you knew.

    The truth is, while metaphysics is among the oldest strands of philosophical thought—an inquiry into the very nature ofreality—metaphysics is also on the cutting edge of today’s scientific discoveries.

    Much has been written to assess his lasting legacy and why he has had such a profound impact on 20th-century readers.As well as delving into the plots of Lewis's enduring works, you will consider questions such as:From the magisterial "Oxford History of English Literature" to children's fantasy books, how did Lewis write with such brilliance and coherence across so many distinct and demanding fields?What were the people, events, and influences that shaped his thought, his character, and the spiritual drama at his life's core?What do Lewis's fictional and factual autobiographies reveal about his conversion and his efforts to "explain and defend the belief that has been common to nearly all Christians at all times"?How did he argue for his ethical notion of "the Tao"—a non-relative set of standards, held widely across all cultures, which modern ideologies often distort?How did he use his apologetical writings to come to grips with perennial spiritual questions involving miracles; the meaning of suffering; the reality of heaven and hell; and the nature of choice, sin, and salvation?How do his scholarly works analyze modern prejudices about the past and offer a vivid, accessible defense of medieval and Renaissance thought?In Lectures 7 through 11, we turn to Lewis the fictional novelist:The unfallen world of Perelandra in the Space Trilogy (1938–45)The beloved Chronicles of Narnia (1950–1956) children's series for which he is perhaps best knownTill We Have Faces (1961), a mature and beautiful reworking of the Cupid and Psyche myth whose heroine is patterned after Lewis's wife, Joy.Professor Louis Markos is a member of Phi Beta Kappa and has won teaching awards at both the University of Michigan and Houston Baptist University. He presents this course as a sympathetic, deeply felt exposition of Lewis's multifaceted thought and works, making no secret of the fact that he is a longtime and enthusiastic fan of Lewis's writings.

    Our language even has a word—Machiavellian—that encapsulates the images those responses conjure up: An indistinct figure quietly making his way through the darkest corridors of power, hatching plots to play one rival against another A cold-blooded political liar, ready to justify any duplicity undertaken in the name of a noble end that will ultimately justify the most malignant means A coolly practical leader—amoral at best—willing to do whatever is necessary in a world governed not by ideas of right or wrong, but by solutions dictated by realpolitik.But does the Machiavelli most of us think we know bear any resemblance to the Machiavelli who lived, pondered, and wrote?According to Professor William R. Cook, a reading of Machiavelli that considers only those qualities that we today call "Machiavellian" is incomplete, and Machiavelli himself "certainly would not recognize" such sinister interpretations or caricatures of his writings and beliefs. Indeed, The Prince—on the pages of which so much of this image was built—was not even published in his lifetime.In the 24 lectures that make up Machiavelli in Context, Professor Cook offers the opportunity to meet an extraordinarily thoughtful and sincere student of history and its lessons, and to learn that there is far more to him than can be gleaned from any reading of The Prince, no matter how thorough.Although The Prince is the work by which most of us think we know Machiavelli, and although some have indeed called it the first and most important book of political science ever written, it was not, according to Professor Cook, either Machiavelli's most important work or the one most representative of his beliefs. Those distinctions belong, instead, to his Discourses on the First Ten Books of Livy, a longer work started at about the same time and which would, like The Prince, not be published until well after his death."Everyone who has seriously studied the works of Machiavelli agrees that he ... believed in the superiority of a republican form of government, defined as a mixed constitution with elements of monarchy, aristocracy, and democracy."Once we recover the context of the writing of The Prince, and analyze it along with the Discourses on the First Ten Books of Livy, it will be clear how The Prince can be read as a book designed to guide leaders in the creation—for Machiavelli, restoration—of republican government in Italy."Ultimately, Machiavelli's goal wasn't much different from ours. It was to live in a free and equal participatory society, because he believed that was the greatest way in which human beings could live and flourish."In fact, says Professor Cook, "Machiavelli's republican thought influenced the development of institutions and values both in Europe and in America."To present a complete and well-rounded picture of Machiavelli's ideas on how human societies should be organized and governed, Professor Cook sets aside much of Machiavelli's written output—which included the political work The Art of War, a biography, many letters, and even some plays—to focus on The Prince, the Discourses, and, more briefly, his Florentine Histories.In doing so, Professor Cook draws on the same qualities so evident in his previous courses for The Teaching Company: Tocqueville and the American Experience, Dante's Divine Comedy, Francis of Assisi, and St. Augustine's Confessions.Teaching in the relaxed and informal style of those courses, Professor Cook moves easily among the different disciplines so pertinent to an understanding of Machiavelli's ideas, including history, philosophy, government, and the elements of leadership. He is unfailingly clear, always provides any definitions needed to understand the material at hand, and is always ready with a touch of wit whenever that is appropriate.Because so much of our contemporary misunderstanding of Machiavelli's ideas comes from a lack of context, Professor Cook carefully sets the stage for a complete perspective of Machiavelli's world.Long before he turns to the works themselves, you'll have learned about Florence and its political history, both before and during Machiavelli's lifetime; the developing Renaissance culture of Machiavelli's time, especially as it bears on the use of ancient political thought by writers and political leaders; and Machiavelli's own life story, including his education, service to the Florentine Republic, years spent in exile south of Florence, and the ways each period of his life affected his writings.The result is a thorough grounding in the information one needs to understand and appreciate this stunningly original thinker.You'll learn, for example, what Machiavelli means when he discusses the important ideas of virtù and Fortuna.Though these are today invariably translated as virtue and fortune, Machiavelli's meanings can involve much more. Though he sometimes uses virtù in the sense we would understand today, he often uses the word—which comes from the classical Latin word for Man—as a means of describing the way one practices successful statecraft: aggressively, with no reluctance to use lies, deceit, and cruelty that may be required to maintain power, and hence the stability the people deserve.In a similar way Machiavelli uses Fortuna in a different sense than might have been used by, say, Dante when he describes the vagaries of fate over which we have no control.Instead, Machiavelli uses the adage, "Fortune is like a river." Though we cannot control fortune, which may well choose to make the river flood, a good ruler, practicing virtù, can indeed prepare for it, and thus modify its effects.You'll see how Machiavelli first became exposed to history and one of its earliest great practitioners—the Roman historian, Livy—through his own experience of Fortuna.Though printed books such as Livy's Early History of Rome were too expensive for a family like the young Machiavelli's in the 15th century, his father did own a copy. He had written the index, and a copy of the book had been part of his payment. Thus Machiavelli grew up with the volumes about which he would one day write his own most important work, Discourses on the First Ten Books of Livy.You'll be introduced to Cesare Borgia, the son of Pope Alexander VI and the man regarded as Machiavelli's model for The Prince, especially in the way his actions embodied the virtù so important to Machiavelli.Professor Cook brings this out in a shocking story of Borgia's use of a tough and merciless Spaniard—Ramiro d'Orco—to impose order and stability on the area of north central Italy known as the Romagna that had come under Borgia's rule and was beset by crime and violence.D'Orco's brutal methods had the desired effect. And when the job was completed, the local people emerged from their homes one morning to find the two halves of Ramiro d'Orco's body on opposite sides of the town square of Cesana, because d'Orco had been too tough, and Cesare Borgia needed a way to advertise further his concern for the people whose loyalty he wanted.The story also embodies, for Machiavelli, the idea that cruelty can be "well-used," just as being merciful—withholding such cruelty when a leader deems it needed—may be less than merciful in its long-term impact.Finally, you will get to see, throughout these lectures, the development of Machiavelli's reliance on history for its lessons, his role as a Renaissance Humanist thinker, and the emergence of his republican views, which still have tremendous influence today as we ask how republics start, grow, succeed, or fail.As Professor Cook notes, we are not going to agree with all of Machiavelli's answers. But his commitment to asking the right questions—to thinking, reflecting, and learning everything history has to teach us about the best ways to govern and safeguard the future—was total.

    But the Black Death was arguably the most significant event in Western history, profoundly affecting every aspect of human life, from the economic and social to the political, religious, and cultural. In its wake the plague left a world that was utterly changed, forever altering the traditional structure of European societies and forcing a rethinking of every single system of Western civilization: food production and trade, the church, political institutions, law, art, and more. In large measure, by the profundity of the changes it brought, the Black Death produced the modern world we live in today.While the story of the Black Death is one of destruction and loss, its breathtaking scope and effects make it one of the most compelling and deeply intriguing episodes in human history. Understanding the remarkable unfolding of the plague and its aftermath provides a highly revealing window not only on the medieval world but also on the forces that brought about the Renaissance, the Protestant Reformation, and modernity itself.Speaking to the full magnitude of this world-changing historical moment, The Black Death: The World's Most Devastating Plague, taught by celebrated medievalist Dorsey Armstrong of Purdue University, takes you on an unforgettable excursion into the time period of the plague, its full human repercussions, and its transformative effects on European civilization. In 24 richly absorbing lectures, you'll follow the path of the epidemic in its complete trajectory across medieval Europe. Majestic in scope and remarkable in detail, this course goes to the heart of one of Western history's most catalytic and galvanizing moments, the effects of which gave us the modern world.

    Yet, as the 1700s began, the mysteries of the universe were pondered by "natural philosophers"—the term "scientist" didn't even exist until the mid 19th century—whose explanations couldn't help but be influenced by the religious thought and political and social contexts that shaped their world.The radical ideas of the Enlightenment were especially important and influential. In this course you see how the work of these natural philosophers prepared the way for the more familiar world of science we recognize today.

    Her parents, profoundly affected by their memories of the Holocaust, pass on, to both Helen and her older sister, a penchant for keeping their lives neatly, even obsessively compartmentalized, and a zealous determination to protect themselves from what they see as danger from the outside world.She delves deeply into the family dynamic that produced such a startling devotion to secret keeping, beginning with the painful and unexpected discovery that she has been disinherited in her mother’s will. In scenes that are frank, moving, and often surprisingly funny, Fremont writes about growing up in such an intemperate household, with parents who pretended to be Catholics but were really Jews—survivors of Nazi-occupied Poland. She shares tales of family therapy sessions, disordered eating, her sister’s frequently unhinged meltdowns, and her own romantic misadventures as she tries to sort out her sexual identity.In a family devoted to hiding the truth, Fremont learns the truth is the one thing that can set you free. Scorching, witty, and ultimately redemptive, The Escape Artist is a powerful contribution to the memoir shelf.

    The infamous Jack the Ripper slayings. The alleged survival of Anastasia Romanov, the youngest daughter of the murdered Tsar. Seven-time Tour de France winner Lance Armstrong's public fall from grace. The Chicago Tylenol poisonings and the copycat crimes that followed. Step into the world of forensic science and study the most fascinating crimes and mysteries from the last two centuries in the 24 lectures of Forensic History: Crimes, Frauds, and Scandals . Professor Murray, a forensic anthropologist with nearly 30 years of experience in the field, has crafted lectures that are a remarkable blend of storytelling and science - a whirlwind tour that takes you from the gas-lit streets of Victorian London to small-town America. As you journey around the world and into the past, you'll re-examine modern history's great crimes and scandals using the tools and insights of forensic science. In doing so, you'll learn how cutting-edge advancements in science and technology are applied to investigations and how to evaluate evidence and think like a forensic scientist. Using her extensive background in the field and her skill at weaving riveting stories, Professor Murray invites you peer over the shoulders of investigators as they examine some of the most famous crimes in history, as well as cases that shed light on what happens when the justice system goes awry. Whether they're controversial or by-the-book, solved or unsolved, hot or cold, these cases are an opportunity to gain deeper insight into the historic and cutting-edge methods and tools forensic scientists use on the job. Having participated in hundreds of investigations in America and abroad, Professor Murray intersperses these historical examinations with some of her own, equally intriguing, personal experiences.Please note there is a 293 page book included in this course so please do not Notabook again.

    Funny. Leaving no stone unturned." . . . So say the publishers about this book I've written. What I say is that this is the story of my life, told as clear as a Texas sky and in the same rhythm that I lived it. It's a story of restlessness and the purity of the moment and living right. Of my childhood in Abbott, Texas, to the Pacific Northwest, from Nashville to Hawaii and all the way back again. Of selling vacuum cleaners and encyclopedias while hosting radio shows and writing song after song, hoping to strike gold. It's a story of true love, wild times, best friends, and barrooms, with a musical sound track ripping right through it. My life gets lived on the road, at home, and on the road again, tried and true, and I've written it all down from my heart to yours. Signed,Willie Nelson

    A leather couch. A neatly bearded, scholarly looking gentleman seated off to the side, only rarely speaking, quietly taking notes and occasionally nodding as the couch's supine occupant tells his or her story.In some ways, such a picture would indeed be accurate, a confirmation not only of the importance of Sigmund Freud in the history of psychology but also of the degree Freud dominates the popular perception of this discipline.But the picture would be inaccurate, as well.Freud was a physician, and the majority of psychologists are not. Both the psychoanalytic theory he pioneered and the therapeutic approach it was based onpsychoanalysishave seen their dominance wane in recent years. And psychologists today, as indebted as they may be to Freud's landmark explorations of our psychological landscape, are involved in far more than helping people cope with inner demons.The expansive and varied roles of contemporary psychologists create another common imageof a crowd of white-coated researchers gathered around a maze, carefully recording a white rat's performance. It's another inadequate picture because experimental psychologists today usually work with people, not animals.Moreover, the areas of interest those psychologists are pursuing now encompass every part of the process we use to develop and function as people:How we perceive, remember, and learnHow we select our friends and partners and retain their affection and loveThe things that motivate us as we make our choices in lifeEven how we relate to the vehicles, machinery, computer systems, or workspaces we encounter as we make our livings.

    Clear Science Teaching to Set the Stage for an Awe-Inspiring Course Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter. Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy. For example, Dr. Tyson begins one lecture at a point 13 billion years ago, when all space, matter, and energy in the known universe were contained in a volume less than one-trillionth the size of a pinpoint-about the size of a single atom. By the time he finishes, the cosmos has been stretched, the planets and our Earth formed, and 70 percent of existing Earth species have been wiped out by a gigantic asteroidclearing the way for the evolution of humanity. Along the way he has touched on Einstein's famous equation, E=mc2; on the four forces that were once unified in the early cosmos in a way physicists are still trying to explain; and on the chemical enrichment of the universe by exploding supernovae, which give the universe its necessary supply of heavier elements including oxygen, nitrogen, iron and, most important, carbon. Carbon, we learn, is a "sticky" atom, capable of making more kinds of molecules than all other elements combined. It's the ideal element with which to experiment in the building of life forms and is, of course, the element responsible for the remarkable diversity of life, including us. As Dr. Tyson notes, we are made of stardust, just as the planets are. And he has created a course that explains exactly how that came to be, beginning with a grounding in the basic "machinery" of matter, forces, and energy that has been discovered on Earth and which also reveals itself throughout the universe. The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe-including its eventual demise-are revealed in stark and often violent beauty. You learn: how Saturn's rings were formed, and why they will eventually be lost why low-density conditions are necessary to produce the drama of the northern and southern auroras why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere how black holes are formed and the extraordinary way in which they can wreak havoc in the universe how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers how astronomers actually look for new planets, why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not. Most important, none of these ideas are presented as isolated "space factoids" that serve no purpose but to entertain. They are there to illustrate and reinforce the key principles of physics and astrophysics that are continually being presented in this course. But the inclusion of real science doesn't prevent Dr. Tyson from having some fun, either. When it's time to show how a black hole might remove one from the universe, he leads you right up to the "event horizon" and slips you in-feet first. Since the event horizon represents the point within which nothing, not even light, can escape, you might think this is a bad idea. And you would be right. But as you plummet toward the "singularity" at the heart of the black hole, you will learn firsthand about the interesting effects of gravity truly unleashed, including what physicists refer to, with a straight face, as "spaghettification." (Actually, Professor Tyson recommends that you be sucked in to a large black hole rather than a small one. You'll still be spaghettified, but it won't happen as quickly.) But make no mistake: Dr. Tyson does not consider the cosmos a laughing matter, this kind of whimsical touch notwithstanding. In spite of his training, he remains, admittedly, still in awe of his subject. And he has created a course that might well produce the same feeling in you.
