Presents historical, religious and philosophical explanations for the existence of evil.

    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.

    While we’re predisposed to look on death with fear and sadness, it’s only by confronting and exploring death head-on that we can actually embrace the important role it plays in our lives. Death, it turns out, is a powerful teacher, one that can help us think responsibly and deeply about the meaning and value of life, connect with the beliefs and traditions of cultures and faiths different from our own, and gain the wisdom and guidance to live a richer, more fulfilling life while we have it.As religion scholar and award-winning Professor Mark Berkson of Hamline University says, “Reflecting on death and dying is an essential part of the examined life.” Take a wide-ranging look at this undeniably confounding and fascinating subject. Bringing together theology, philosophy, biology, anthropology, literature, psychology, sociology, and other fields, these 24 lectures are a brilliant compendium of how human beings have struggled to come to terms with mortality. You’ll encounter everything from ancient burial practices, traditional views of the afterlife, and the five stages of grief to the question of killing during wartime, the phenomenon of near-death experiences, and even 21st-century theories about transcending death itself. Prepare for a remarkable learning experience that brings you face-to-face with the most important topic mortals like us can consider.

    Owing to the work of an astonishing range of visionary thinkers, this fascinating period was the era in which the foundations of the modern Western world were laid. In the medieval era's great minds we find the roots of many aspects of today's world - from the religious/philosophical thought of Augustine, Ambrose of Milan, and Thomas Aquinas to the scientific innovations of Avicenna and Alhacen, the enlightened statesmanship of Charlemagne and Lorenzo de Medici, and the literary creations of Dante and Chaucer.In these 24 lectures, Professor Armstrong leads you on an enthralling journey into the lives of the seminal thinkers of the Middle Ages. In this gallery of extraordinary minds, you'll encounter the leading lights of a world-shaping era, including figures such as Maimonides, Hildegard of Bingen, Bernard of Clairvaux, Peter Abelard, and Francesco Petrarch. Professor Armstrong goes to great lengths to bring these historic figures to life, revealing both the great intellectual contributions and the personal strivings, challenges, and triumphs of some of history's most remarkable human beings. These compelling lectures take you deeply into the heart of one of civilization's most dynamic and impactful eras.Listening Length: 11 hours and 59 minutes

    Nothing you experience would be possible without the intricate power of your senses. But how much about them do you really know?Your ability to sense and perceive the world around you is so richly detailed and accurate as to be miraculous. No tool in the entire universe of scientific exploration can come close to matching the ability of your brain to use information sensed by your eyes, ears, skin, tongue, and nose to produce a rich sensory experience in just milliseconds.In recent years, neurobiologists and other scientists have uncovered new insights into how your senses work and the amazingly complex and fascinating things they can do. And now you can share in what they've discovered-through this intriguing series of 24 lectures from an award-winning teacher.Knowing how your senses work and the ways they shape how you see, interact with, and understand your life will help you think more critically about everything you sense and perceive, strengthen your appreciation of the senses that make this possible, prepare you to be an active consumer of new scientific evidence on how our senses work, and much more.With Professor Vishton as your guide, you'll. consider each of your senses from multiple perspectives:Explore how your brain processes different sensory informationConsider how your senses work together and within the context of the environment around youdiscover how your senses connect you to the world and other people.Using both cutting-edge research and simple experiments, tests, and demonstrations to hone your understanding, he has created a world-class learning experience that will change the way you think about your senses.

    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.

    The answer to this age-old riddle is universally relevant to our lives. The implications of our views on it can affect everything from small choices we make every day to our perspective on criminal justice and capital punishment. From the Stoics to Boethius, from Kant to Hume, from Sartre to contemporary philosophers, great minds have puzzled over this debate for centuries.Now you can learn the intriguing details of this fundamental philosophical question with Great Philosophical Debates: Free Will and Determinism, 24 fascinating lectures by Shaun Nichols, award-winning Professor of Philosophy and Cognitive Science at the University of Arizona."The Great Courses.com

    (B) Scientific knowledge is always provisional and tells us nothing that is universal, necessary, or certain about the world. Welcome to the science wars—a long-running battle over the status of scientific knowledge that began in ancient Greece, raged furiously among scientists, social scientists, and humanists during the 1990s, and has re-emerged in today's conflict between science and religion over issues such as evolution.Professor Steven L. Goldman, whose Teaching Company course on Science in the 20th Century was praised by customers as "a scholarly achievement of the highest order" and "excellent in every way," leads you on a quest for the nature of scientific reasoning in this intellectually pathbreaking lecture series, Science Wars: What Scientists Know and How They Know It.Those who have taken Professor Goldman's previous course, which is an intensive survey of the revolution in scientific knowledge from 1900 to 2000, may have wondered: if what counts as scientific knowledge can transform so dramatically within only 100 years, what exactly is scientific knowledge? Science Wars addresses this surprisingly difficult question.Five Centuries of the Science WarsIn 24 half-hour lectures, Science Wars explores the history of competing conceptions of scientific knowledge and their implications for science and society from the onset of the Scientific Revolution in the 1600s to the present. It may seem that the accelerating pace of discoveries, inventions, and unexpected insights into nature during this period guarantees the secure foundations of scientific inquiry, but that is far from true. Consider these cases:The scientific method: In the 1600s the English philosopher Francis Bacon defined the scientific method in its classic form: the use of inductive reasoning to draw conclusions from an exhaustive body of facts. But "no scientist has ever been a strict Baconian," says Professor Goldman. "If you followed that, you would get nowhere."A "heated" debate: Around 1800 the dispute over the nature of heat was resolved in favor of the theory that heat is motion and not a substance given off during burning. But then the French mathematical physicist Joseph Fourier wrote a set of equations that accurately described how heat behaves regardless of what it "really" is, which, Fourier contended, was not a scientific question at all.Paradigm shifts: The publication in 1962 of Thomas Kuhn's The Structure of Scientific Revolutions precipitated a radical change in attitudes toward scientific knowledge, prompted by Kuhn's insight that science is not an entirely rational enterprise, and that its well-established theories (or paradigms) are overturned in a revolutionary, nonlogical process.Postmodern putdown: The postmodern attack on science as a privileged mode of inquiry made some headway in the late 20th century. But the credibility of the movement wilted in 1996, when a postmodern journal unwittingly published a spoof by physicist Alan Sokal, purporting to prove that physical theory was socially constructed. Sokal then exposed his piece as a parody.In the penultimate lecture of the course, Professor Goldman considers intelligent design—the argument that evolution can't account for the immense complexity of life and that a master designer must be at work. He approaches this topical debate by asking: What are the minimum criteria that define a hypothesis as scientific, and does intelligent design qualify? Having already covered five centuries of the science wars in the previous lectures, you will analyze this controversy with a set of tools that allows you to see the issues in a sharp, new light.What Is Reality?"Fasten your seatbelts," says Professor Goldman at the outset of Lecture 21—an advisory that applies equally to the whole course, which covers an astonishing array of ideas and thinkers. Throughout, Professor Goldman never loses his narrative thread, which begins 2,400 years ago with Plato's allegorical battle between "the gods" and "the earth giants"—between those for whom knowledge is universal, necessary, and certain; and those for whom it cannot be so and is based wholly on experience.The problem of what constitutes scientific knowledge can be illustrated with one of the most famous and widely accepted scientific theories of all time, Nicolaus Copernicus's heliostatic (stationary sun) theory of the solar system, which has undergone continual change since it was first proposed in 1543: Copernicus called for the planets to move in uniform circular motion around the sun, slightly displaced from the center. Using observations by Tycho Brahe, Johannes Kepler revised the Copernican model, discarding the ancient dogma of circular motion, which did not fit the data. Instead, he guessed that the planets in fact move in elliptical orbits. In his influential work endorsing the Copernican theory, Galileo ignored Kepler's corrections and opted for circular motion. Notoriously, the Catholic Church condemned Galileo for heresy. But the church was actually correct that he had no basis for claiming the heliocentric theory was true, rather than simply an interpretation of experience. Galileo's picture of space was superseded by Newton's and later by Einstein's, which also will doubtless be revised. Even something as basic as the elliptical motion of the planets is a vast oversimplification. There are no closed curves in space, since the solar system is moving around the center of the galaxy; the galaxy is moving within the local cluster; and the local cluster is also moving. Although we still call the conventional picture of the solar system Copernican astronomy, there is effectively no resemblance between astronomy today and Copernicus's 1543 theory of the heavens. The same is also true of other theories, such as the atomic theory of matter. All scientific theories are in a state of ceaseless revision, which raises the question of what reality "really" is. As the contemporary philosopher of science Mary Hesse has pointed out, the lesson of the history of science seems to be that the theories we currently hold to be true are as likely to be overturned as the theories they replaced!Sharpen Your Understanding of What Science IsThe uncertainty about the status of scientific knowledge and about the objectivity of the scientific enterprise led to a broad assault on science in the late 20th century by sociologists, philosophers, and historians, many connected with the postmodern movement. The lectures covering this attack and the ensuing counterattack by scientists are some of the most thrilling in the course and involve a number of figures whom Professor Goldman knows personally.Of one of the firebrands in this conflict, the late Viennese philosopher of science Paul Feyerabend, Professor Goldman says, "I myself took a seminar with Feyerabend when he was teaching at Berkeley in the early 1960s. … Feyerabend was not really off the wall, although he was often depicted that way. … He too recognized, as everyone must, that after all, science does work and science is knowledge of a sort. It's just not the absolute knowledge that scientists and philosophers have historically claimed that it is."By the time you reach the end of this course, you will understand exactly what science is, and you will be enlightened about a fascinating problem that perhaps you didn't even know existed. "There have been a raft of popular books about what scientists know," says Professor Goldman, "but to the best of my knowledge, there is not a single one of these popular books that focuses centrally on the question of how scientists know what they know."This course serves as that book.Course Lecture Titles1.

    But the very existence of consciousness raises profound questions: Why would any collection of matter in the universe be conscious? How are we able to think about this? And why should we?In this wonderfully accessible book, Annaka Harris guides us through the evolving definitions, philosophies, and scientific findings that probe our limited understanding of consciousness. Where does it reside, and what gives rise to it? Could it be an illusion, or a universal property of all matter? As we try to understand consciousness, we must grapple with how to define it and, in the age of artificial intelligence, who or what might possess it. Conscious offers lively and challenging arguments that alter our ideas about consciousness—allowing us to think freely about it for ourselves, if indeed we can.

    Modern science demonstrates that this mental hardwiring, traceable to the survival needs of our earliest ancestors, is at the root of many of the psychological and behavioral problems that we face today.For thousands of years, people have used mindfulness practices—techniques to develop awareness of present experience with acceptance—to deal effectively with a wide range of life challenges. And, a large and fascinating body of scientific research now validates the remarkable benefits of mindfulness practice for psychological as well as physical health.But how exactly does mindfulness work, in scientific terms? How can understanding the science and practice of mindfulness improve everyday life? And how can the human brain, whose very functioning gives rise to so many of the problems we struggle with, actually provide a solution?Now, in the 24 fascinating lectures of The Science of Mindfulness, Professor Ronald D. Siegel, a clinical psychologist on the faculty of Harvard Medical School, reveals the science behind mindfulness in compelling detail and demonstrates its application to an extraordinary range of human problems—psychological, social, and medical. You’ll closely examine the neurobiology involved, leaving you with a clear knowledge of the science underlying ancient practices that are now profoundly influencing the contemporary world. And you’ll learn many practical ways you can use mindfulness techniques in your own life.

    What makes you happy? Where did your personality come from? Why do you have trouble controlling certain behaviors? Why do you behave differently as an adult than you did as an adolescent? Since the start of recorded history, and probably even before, people have been interested in answering questions about why we behave the way we do. And many fields - including philosophy, psychology, and even theology - are focused on finding explanations. But it's only in recent decades that researchers can finally approach, understand, and solve the mysteries of emotion, thought, and behavior - solutions that help each of us to better know ourselves and the people around us. The result is not only a more solid understanding of what it means to be human, but a stronger foundation from which to live more effectively with others and to grasp their intricate behaviors and quirks. Now you can gain those benefits through a series of 24 intriguing lectures from an award-winning teacher. Professor Leary takes you on a fascinating journey into the complex heart of who you are, using the latest theories, case studies, experiments, and stories to cast light on a wide variety of human behaviors, both ordinary and puzzling. Throughout these lectures, you'll learn about the various interacting forces that influence your behavior. These include your genetic blueprint, your personal experiences, your upbringing, and the people and social groups that surround you.

    It promised to shed light on the deep mysteries of consciousness, as well as offer relief to addicts and the mentally ill. But in the 1960s, with the vicious backlash against the counter-culture, all further research was banned. In recent years, however, work has quietly begun again on the amazing potential of LSD, psilocybin and DMT. Could these drugs in fact improve the lives of many people? Diving deep into this extraordinary world and putting himself forward as a guinea-pig, Michael Pollan has written a remarkable history of psychedelics and a compelling portrait of the new generation of scientists fascinated by the implications of these drugs. How to Change Your Mind is a report from what could very well be the future of human consciousness.

    One of the first paleoanthropologists to study fossil evidence and genetic information together in order to test hypotheses about human prehistory, Professor Hawks is adept at looking at human origins not just with one lens, but with two.He has traveled around the world to examine delicate skeletal remains and pore over the complex results of genetic testing. His research and scholarship on human evolutionary history has been featured in a variety of publications, including Science, American Journal of Physical Anthropology, Slate, and Journal of Human Evolution.But more than that, Professor Hawks has crafted a course that demonstrates the passion and excitement involved in the field of paleoanthropology. With his engaging lecturing style and his use of fossil finds taken from his personal collection, Professor Hawks will capture your attention and show you all the drama and excitement to be found in eavesdropping on the latest debates about human evolutionary history.
