Whether it’s a friend who can’t quit smoking, a colleague afflicted with alcoholism, or a relative abusing prescription drugs, we all know someone who suffers from some form of addiction—we may even have an addiction ourselves. By some estimates, roughly one in four Americans might be considered addicts. On the other hand, many of us use substances such as alcohol recreationally, without suffering the physical or psychological symptoms of addiction. So what is the difference between drug use, abuse, and clinical addiction? What causes addictions? What happens when your brain is on drugs, and why do addicts behave the way they do?12 Lectures 1.

    His language and culture - those of Elizabethan England - are greatly different from our own, and his poetry, thick with metaphorical imagery and double meanings, can be hard to penetrate.Yet the keys to understanding Shakespeare are written into the plays themselves. If you can learn to recognize the playwright's own clues, you'll become able to engage meaningfully with his language, to follow the plot structures and themes that drive his plays, and to track the development of his characters.Over the course of 24 lectures, this innovative and penetrating exploration of Shakespeare's plays reveals how to enter Shakespeare's dramatic world, how to grasp what's happening in any of his plays, and how to enjoy them fully both on the page and the stage.Under Professor Conner's expert guidance, shaped by decades of studying and performing Shakespeare, you learn more than 40 interpretive tools, drawn from the texts themselves, that give you direct insight into the plays. These guiding principles allow you to follow the narratives of the plays as they unfold, with a clear understanding of how the plays function and fit together.The professor also reveals fascinating details of Shakespeare's era, which shed further light on the plays and the way his contemporary audiences perceived them.This course builds the skills that allow you to reach your own understanding of the plays - to deeply comprehend Shakespeare's transcendent poetic language, the spellbinding world of his great characters and stories, and his revelatory reflections on human experience.Disclaimer: Please note that this recording may include references to supplemental texts or print references that are not essential to the program and not supplied with your purchase.©2013 The Teaching Company, LLC (P)2013 The Great Courses

    What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? The Theory of Evolution: A History of Controversy is an examination of the varied elements that so often make this science the object of strong sentiments and heated debate. Professor Edward J. Larson leads you through the "evolution" of evolution, with an eye toward enhancing your understanding of the development of the theory itself and the roots of the controversies that surround it. In these lectures you will: Explore pre-Darwinian theories of the origins of life, from Genesis and the ancient Greeks to such 18th- and 19th-century scientists as Georges Cuvier and Chevalier de Lamarck Follow the life and work of Charles Darwin, and the impact of his 1859 masterpiece, On the Origin of Species. Darwin's theory of evolution by natural selection was immediately recognized as a threat to traditional religion, but was quickly accepted (the first printing of Origin of Species sold out on the first day) Examine the history of evolutionary science after Darwin-a fascinating story that includes the "rediscovery," after 35 years, of Gregor Mendel's work on genetic variation; the unearthing of prehominid, or early human, fossils by Raymond Dart in 1925 and the Leakey family in the 1950s; and the confusion created by the sensational, but later discredited, discovery of Piltdown Man-a fake evolutionary "missing link"-in 1912 Trace the history of religious objections to evolution, from those of Darwin's own time to contemporary efforts to teach creation science in American schools. This includes a detailed discussion of the famous Scopes "monkey trial," which in fact was a staged media event, designed to create publicity for the town of Dayton, Tennessee. Are Our Genes more Important than We Are? This course makes it clear that the history of controversy surrounding evolution is not limited to a dispute between science and religion. Even within the scientific community, the fine details of the theory of evolution have long been a matter of passionate dispute. In fact, in the last third of the 19th century, the principal objections were scientific, not religious. Although the fossil record was a key piece of evidence for evolution, it had gaps that could be used to argue against the theory. And both proponents and critics wondered how altruistic human qualities such as love and generosity could possibly have evolved through the competitive, often harsh, processes that Darwin described. From Professor Larson's presentation, you will learn that new ideas in evolution science have often created new controversies. For example, is it truly possible, as some scientists now maintain, that humans exist merely to ensure the survival of their genes? Such research has created disagreement among scientists about the degree to which evolution drives human behavior, and has further alienated many segments of the public. Evolution's "Dark Side": Social Darwinism In these lectures, you will review perhaps the most sinister controversy associated with the theory of evolution: social Darwinism. From the beginning, the Darwinian theory of evolution has been linked to economic and political views. Thomas Malthus's theories of population growth and competition for limited resources even inspired Darwin's thinking on natural selection. Unfortunately, later supporters of evolution carried this line of thinking too far. Beginning with Herbert Spencer, who coined the term "survival of the fittest," Darwin's ideas were used as evidence for a wide range of social beliefs, from laissez-faire capitalism to racism, colonialism, and, in perhaps the worst application, Nazism. In the United States, social Darwinism has served as a basis for the creation of IQ tests and for eugenics programs that resulted in the forced sterilization of thousands of mentally ill or retarded Americans. Unsettling Implications: The Growing Gulf Between Science and Religion During the late 19th century, largely through the efforts of scientists who sought to integrate evolutionary science with spiritual belief, evolution was widely accepted by the religious community in the United States. Today, this is hardly the case. In his last four lectures, Professor Larson examines the trends that have, since 1920, widened the gulf between science and religion. These include an increase in fundamentalist Protestantism, the weakening of liberal Protestantism as a counteracting force, and the growing power of a firmly conservative South. In the 1960s, federally funded neo-Darwinian textbooks provoked a conservative backlash. Beginning with the publication of Henry M. Morris's The Genesis Flood, efforts to gain equal time for the teaching of creation science, based on biblical teachings, gathered strength. Rebuffed by the courts, creationism continues to thrive through the increasing numbers of private Christian schools and through home schooling. The growing gulf between science and religion has unsettling implications for our society. Large segments of the American population reject the naturalism of current evolutionary thinking. Nine of 10 Americans believe in spiritual causes for life, with only 10 percent accepting the purely naturalistic explanations espoused by evolution. Strikingly, these statistics are almost exactly the opposite among the scientific community. A Pulitzer Prize-Winning Teacher As both a historian of science and a professor of law, Professor Edward J. Larson brings exceptional qualifications to this subject. His book, Summer for the Gods: The Scopes Trial and America's Continuing Debate Over Science and Religion, won the 1998 Pulitzer Prize in History. His analysis provides an invaluable perspective on the volatile history of what is arguably the single most significant idea of modern times.

    Heroes are not only brave, but they’re also able to navigate the convoluted corridors of society, and to see through the respectable pretense of others to detect the evil that lies within. So, who better to take on the foggy, crime-ridden streets and strict social mores of Victorian London than the iconic literary detective Sherlock Holmes?In Sherlock Holmes: Beyond the Elementary, you’ll investigate the history behind Sir Arthur Conan Doyle’s whip-smart, charismatic detective. James Krasner, a scholar of British Victorian literature, will play the role of “Watson”, as he offers a clearer picture of the imaginative influence Sherlock Holmes has maintained over readers, from the 19th century through today. While you examine the secrets of novels like A Study in Scarlet and The Hound of the Baskervilles and stories like “A Scandal in Bohemia” and “The Final Problem”, you’ll deepen your appreciation of these enduring works. You’ll also gain insights into Holmes’ continued relevance to the social problems we face in our own world.What does the relationship between Holmes and Watson tell us about friendship? Is Sherlock Holmes just a “thinking machine”? How do these adventures lay bare gender dynamics in surprising ways? The answers are far from elementary.

    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.

    The celebrated Macedonian king has been one of the most enduring figures in history. He was a general of such skill and renown that for two thousand years other great leaders studied his strategy and tactics, from Hannibal to Napoleon, with countless more in between. He flashed across the sky of history like a comet, glowing brightly and burning out quickly: crowned at age nineteen, dead by thirty-two. He established the greatest empire of the ancient world; Greek coins and statues are found as far east as Afghanistan. Our interest in him has never faded. Alexander was born into the royal family of Macedonia, the kingdom that would soon rule over Greece. Tutored as a boy by Aristotle, Alexander had an inquisitive mind that would serve him well when he faced formidable obstacles during his military campaigns. Shortly after taking command of the army, he launched an invasion of the Persian empire, and continued his conquests as far south as the deserts of Egypt and as far east as the mountains of present-day Pakistan and the plains of India. Alexander spent nearly all his adult life away from his homeland, and he and his men helped spread the Greek language throughout western Asia, where it would become the lingua franca of the ancient world. Within a short time after Alexander’s death in Baghdad, his empire began to fracture. Best known among his successors are the Ptolemies of Egypt, whose empire lasted until Cleopatra. In his lively and authoritative biography of Alexander, classical scholar and historian Philip Freeman describes Alexander’s astonishing achievements and provides insight into the mercurial character of the great conqueror. Alexander could be petty and magnanimous, cruel and merciful, impulsive and farsighted. Above all, he was ferociously, intensely competitive and could not tolerate losing—which he rarely did. As Freeman explains, without Alexander, the influence of Greece on the ancient world would surely not have been as great as it was, even if his motivation was not to spread Greek culture for beneficial purposes but instead to unify his empire. Only a handful of people have influenced history as Alexander did, which is why he continues to fascinate us.

    In each hour of the day we meet a new character - from emperor to slave girl, gladiator to astrologer, medicine woman to water-clock maker - and discover the fascinating details of their daily lives.

    Above all else, Cleopatra was a shrewd strategist and an ingenious negotiator.Though her life spanned fewer than forty years, it reshaped the contours of the ancient world. She was married twice, each time to a brother. She waged a brutal civil war against the first when both were teenagers. She poisoned the second. Ultimately she dispensed with an ambitious sister as well; incest and assassination were family specialties. Cleopatra appears to have had sex with only two men. They happen, however, to have been Julius Caesar and Mark Antony, among the most prominent Romans of the day. Both were married to other women. Cleopatra had a child with Caesar and–after his murder–three more with his protégé. Already she was the wealthiest ruler in the Mediterranean; the relationship with Antony confirmed her status as the most influential woman of the age. The two would together attempt to forge a new empire, in an alliance that spelled their ends. Cleopatra has lodged herself in our imaginations ever since.Famous long before she was notorious, Cleopatra has gone down in history for all the wrong reasons. Shakespeare and Shaw put words in her mouth. Michelangelo, Tiepolo, and Elizabeth Taylor put a face to her name. Along the way, Cleopatra’s supple personality and the drama of her circumstances have been lost. In a masterly return to the classical sources, Stacy Schiff here boldly separates fact from fiction to rescue the magnetic queen whose death ushered in a new world order. Rich in detail, epic in scope, Schiff ‘s is a luminous, deeply original reconstruction of a dazzling life.

    King (William and Mary University) delves into the story of how, why, where, and when we became human. These lectures will help you understand the forces that have shaped, and continue to shape, our species. "An evolutionary perspective on human behavior," notes Dr. King, "results in more than just knowledge about dates and sites when and where specific evolutionary milestones likely occurred." "It is also a window on the past and future of our species. An entirely new way of thinking comes into focus when we consider the human species within an evolutionary perspective."A Century of ScholarshipWhile covering these subjects in this 24-lecture series, Dr. King synthesizes the best that more than a century of scientific scholarship has to offer across a variety of disciplines. Biological anthropologists study primate anatomy and behavior both to understand evolution and to learn more about our common ancestor. Biological anthropologists are joined by molecular anthropologists to better understand hominids by studying fossils, ancient skeletal remains, and lifestyle information such as cave art and stone tools. Case Studies that Clarify Evolution and Its Power Dr. King begins by explaining key mechanisms through which evolution functions, citing famous and definitive case studies that demonstrate these forces. In one such landmark study, for example, biologists Peter and Rosemary Grant returned to the Galapagos Islands more than 100 years after Darwin's first voyage to conduct research on island finches. In 1977, a drought-induced scarcity of soft, edible seeds brought forth in the very next generation a population of finches with larger, stronger beaks capable of crushing larger, tougher seeds. Extraordinarily, in 1985, heavy rains produced a surplus of softer seeds, and natural selection produced a succeeding generation of the smaller-beaked variety. Evolution had occurred in two different directions within a decade. This "natural selection" is the theoretical tool of evolution, which helps us make sense of these facts. Why Evolution Remains Important to Us Today Perhaps the greatest measure of this theory's power is its relevance to our lives today. - Did you know that the gene which causes sickle cell anemia must be inherited from both parents to cause the disease but the disease does not occur when only a single gene is inherited? - Or that the single gene, in fact, affords protection from malaria? Or that race, a category so securely ingrained in our consciousness, is practically meaningless in biological terms? - Or how to evaluate the claim that a gene can be responsible for a certain personality trait? A Glimpse Into Our Selected Primate Heritage With an understanding of the basic mechanisms of evolutionary change in hand, the course looks at how our ancient primate ancestors adapted. Consider the anatomical features we share with monkeys, great apes, and other primates. Our large brains, grasping hands, and forward-facing eyes allowing us to perceive depth are critical to the way we function in the world. Yet the fossil record tells us that some 70 million years ago these distinctive primate features did not exist. What caused the first primates to emerge from existing mammalian populations? One proposed solution was that the appearance of insects living in the lower canopies of trees offered a plentiful food resource to those species adapted to procure it. Could depth perception and grasping ability have provided an advantage here, and hence been naturally selected? This is the function of biological anthropology: confronting the facts, then suggesting and testing possibilities. A Course as Much About the Present as the PastWith so much of evolutionary history taken up with the past, the insights gained in these lectures may tempt you to add questions of your own: - Is human evolution still a force in today's world? Hasn't our modern, mobile culture rendered evolution irrelevant? - In fact, human evolution is a stronger force than ever, interacting with human culture in complex ways. Issues such as obesity, AIDS, and genetics are all discussed. And you may well find these lectures opening your eyes to the extraordinary ways in which the biological power of natural selection is still at work in the world today. Course Lecture Titles1.

    Beginning with King Arthur, Professor Madden peels back layers of exaggeration and fiction to lay bare the historical basis for the mythological king. Madden then examines myths of the medieval church, sexual myths of the Middle Ages, and myths about Robin Hood and the Shroud of Turin, all the time imparting an understanding of just what medieval people thought about their planet. Contents: King Arthur: man vs. myth -- Medieval and modern mysteries of the Holy Grail -- A female Pope? The myth and legends of Pope Joan -- Burn them all: witches and inquisitors in the Middle Ages -- Medieval sexual myths: chastity belts and the Lord's "right of first night" -- Splitting arrows: the history and myth of Robin Hood -- Sailing off the edge of the world: the myth of the flat Earth -- Is the Shroud of Turin a Medieval forgery?

    For instance, it's not hard to envision a day when websites such as Facebook or Google Maps introduce a feature that allows real-time tracking of anyone you want, based on face-recognition software and ubiquitous live video feeds.Does this scenario sound like an unconstitutional invasion of privacy? These 24 eye-opening lectures immerse you in the Constitution, the courts, and the post-9/11 Internet era that the designers of our legal system could scarcely have imagined. Professor Rosen explains the most pressing legal issues of the modern day and asks how the framers of the U.S. Constitution and the Bill of Rights would have reacted to aspects of the modern life such as full-body scans, cell phone surveillance, and privacy in cloud servers.Called "the nation's most widely read and influential legal commentator" by the Los Angeles Times, Professor Rosen is renowned for his ability to bring legal issues alive - to put real faces and human drama behind the technical issues that cloud many legal discussions. Here he asks how you would decide particular cases about liberty and privacy. You'll come away with a more informed opinion about whether modern life gives even the most innocent among us reason to worry.

    Like their acclaimed bestseller George Washington's Secret Six, Thomas Jefferson and the Tripoli Pirates sheds new light on a vitally important episode that has been forgotten by most Americans.   Only weeks after President Jefferson's inauguration in 1801, he decided to confront the Tripoli pirates who had been kidnapping American ships and sailors, among other outrageous acts. Though inclined toward diplomacy, Jefferson sent warships to blockade Tripoli and protect American shipping, and then escalated to all-out war against the Barbary states.   The tiny American flotilla—with three frigates representing half of the U.S. Navy’s top-of-the-line ships—had some success in blockading the Barbary coast. But that success came to an end when the USS Philadelphia ran aground in Tripoli harbor and was captured. Kilmeade and Yaeger recount the dramatic story of a young American sailor, Stephen Decatur, who snuck into the harbor, boarded the Philadelphia, and set her on fire before escaping amid a torrent of enemy gunfire.   Another amazing story is that of William Eaton’s daring attack on the port city of Derna. He led a detachment of Marines on a 500-mile trek across the desert to surprise the port. His strategy worked, and an American flag was raised in victory on foreign soil for the first time.     Few remember Decatur and Eaton today, but their legacy inspired the opening of the Marine Corps Hymn: “From the halls of Montezuma to the shores of Tripoli, we fight our country’s battles in the air, on land, and sea.” Thomas Jefferson and the Tripoli Pirates tells a dramatic story of bravery, diplomacy, and battle on the high seas, and honors some of America’s forgotten heroes.
