But is old age all doom and gloom?Not at all! While it's true that some functions in the aging brain decline, neuroscientists have discovered that many other brain functions remain stable - or even improve - as we age. Furthermore, nurture plays as significant a role as nature, and there are a number of strategies you can implement to stave off declining brain function, including:Incorporating physical activity into your routineEating a healthy dietMaintaining a vibrant social lifeReducing your stressThe science behind the aging brain tells a fascinating - and often counterintuitive - story. Is "aging" a disease or merely a natural occurrence that produces disease-like symptoms? If humans are biologically programmed to survive and thrive, why do we age at all? Is it possible (or even desirable) to "cure" aging altogether?Delve into these questions and more in The Aging Brain. Taught by a neuroscientist and award-winning professor at the University of Michigan, these 12 eye-opening lectures will give you a wealth of new insights into what happens to the brain over time - as well as strategies to mitigate the effects of aging and enhance your quality of life into old age.With a mix of scientific research and practical applications, Professor Polk brings cutting-edge science to life. He takes you down to the cellular and even molecular levels of the brain to show you why certain functions decline, how some aspects of brain aging are under genetic control, and what you can do to prolong your health and keep your mind sharp. Aging affects us all, but you have some control over how it affects you.

    But there is a method for avoiding such pitfalls of human nature, and it's called skepticism. By using rational inquiry and seeing subjects from a scientific perspective, we can approach even the most sensitive claims with clear eyes to ultimately arrive at the truth. During 18 lectures that will surprise, challenge, and entertain you, you will learn how to think, not just what to think-and you'll come to understand why extraordinary claims require extraordinary evidence.You'll discover how skepticism can help differentiate between real science and pseudoscience, as well as between "scientific" history and pseudohistory-distinctions that have serious educational and political implications.Fascinating case studies illustrate how you can apply the methods of skepticism to detect specious claims and faulty logic in any scenario you encounter such as:•The methodology employed by Holocaust deniers•Arguments made by proponents of creationism•The biology of near-death experiences and the sensed-presence effect•Psychic abilities and other "paranormal" phenomena.As you learn how our brains work to form beliefs, you'll examine the classic fallacies of thought that lead us to experience mistakes in thinking and to form bad arguments in favor of our beliefs.Is there a God? Is there life after death? Is there a basis for morality without God? Skepticism 101 doesn't shy away from controversial questions, nor does it give final answers. What it offers are methods and hard evidence for rationally evaluating various claims and positions, and an opportunity to understand why you believe what you believe.Listening Length: 9 hours and 10 minutes

    There are good reasons that language fascinates us so. It not only defines humans as a species, placing us head and shoulders above even the most proficient animal communicators, but it also beguiles us with its endless mysteries. For example: * How did different languages come to be? * Why isn’t there just a single language? * How does a language change, and when it does, is that change indicative of decay or growth? * How does a language become extinct? Dr. John McWhorter, one of America’s leading linguists and a frequent commentator on network television and National Public Radio, addresses these and other questions as he takes you on an in-depth, 36-lecture tour of the development of human language, showing how a single tongue spoken 150,000 years ago has evolved into the estimated 6,000 languages used around the world today.An accomplished scholar, Professor McWhorter is also a skilled popularizer, whose book The Power of Babel was called "startling, provocative, and remarkably entertaining," by the San Diego Union-Tribune.The London Times called him "a born teacher." And Steven Pinker, best known as the author of The Language Instinct, offered this praise for the book: "McWhorter’s arguments are sharply reasoned, refreshingly honest, and thoroughly original."Course Lecture Titles1.

    They affect how we grant legitimacy to authority, define what is possible, create standards of right and wrong, and even view the potential of human life. Between 1600 and 1800, such a revolution of the intellect seized Europe, shaking the minds of the continent as few things before or since. What we now know as the Enlightenment challenged previously accepted ways of understanding reality, bringing about modern science, representative democracy, and a wave of wars, sparking what Professor Kors calls, "perhaps the most profound transformation of European, if not human, life."In this series of 24 insightful lectures, you'll explore the astonishing conceptual and cultural revolution of the Enlightenment. You'll witness in its tumultuous history the birth of modern thought in the dilemmas, debates, and extraordinary works of the 17th and 18th-century mind, as wielded by the likes of thinkers like Bacon, Descartes, Hobbes, Pascal, Newton, Locke, Hume, Voltaire, Diderot, and Rousseau.And you'll understand why educated Europeans came to believe that they had a new understanding - of thought and the human mind, of method, of nature, and of the uses of knowledge - with which they could come to know the world correctly for the first time in human history, and with which they could rewrite the possibilities of human life.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.

    Principe on the relation between science and religion from early times to the present.Two crucial forces, science and religion, helped shape Western civilization and continue to interact in our daily lives. What is the nature of their relationship? When do they conflict, and how do they influence each other in pursuit of knowledge and truth? Contrary to prevailing notions that they must perpetually clash, science and theology have actually been partners in an age-old adventure. This course covers both the historical sweep and philosophical flashpoints of this epic interaction.6 audio discs (1 hour each); 68-page course guidebook which includes professor biography, statement of course scope, lecture outlines and notes, a timeline, glossary, biographical notes, and bibliography.Lecture 1. Science and religionLecture 2. The warfare thesisLecture 3. Faith and reason: Scripture and natureLecture 4. God and nature: Miracles and demonsLecture 5. Church, Copernicus, and GalileoLecture 6. Galileo's trial. Lecture 7. God the watchmakerLecture 8. Natural theology and arguments from designLecture 9. Geology, cosmology, and Biblical chronologyLecture 10. Darwin and responses to evolutionLecture 11. Fundamentalism and creationismLecture 12. Past, present, and future

    This course explores the archeology, publication, content, and interpretations of the historical period of the scrolls.

    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.

    When most of us study philosophy, we're focusing only on the Western intellectual tradition brought about by people such as Aristotle, Descartes, and Nietzsche. But to understand the Western intellectual tradition is to only get half of the story.Great Minds of the Eastern Intellectual Tradition is an epic, comprehensive survey of the East's most influential philosophers and thinkers. In 36 lectures, award-winning Professor Grant Hardy of the University of North Carolina at Asheville introduces you to the men and women responsible for molding Asian philosophy and for giving birth to a wide variety of spiritual and ideological systems, including Hinduism, Daoism, Confucianism, Sufism, and Buddhism. By focusing on these key thinkers in their historical contexts, you'll witness the development of these rich traditions as they shaped and defined Eastern cultures through the rise and fall of empires, the friendly and hostile encounters with each other and with the Western world, and the rapid advancements of the modern age.

    Each part contains six audio tapes and a booklet.

    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.

    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.

    From liberty to democracy to community, the terms and concepts originated by political philosophers are ingrained in our global consciousness. Yet many of us have an incomplete picture of how these ideas developed and, quite possibly, a skewed perception of their intentions and implications.This highly relevant course sheds light on the labyrinth of Western political and social theory, as well as its influence on modern history. Guided by an award-winning professor of philosophy and author, these eye-opening lectures reveal how political philosophers, in responding to the societal problems and changing conditions of their day in revolutionary ways, created virtual blueprints of action for leaders. You'll gain not only the tools to comprehend the omnipresent language of politics, but a thorough understanding of the wellspring of thought that has emerged over centuries of political philosophy and the intellectual origins of major historical movements and events.Throughout, questions of democracy, freedom, and distributive justice are addressed, and revolutionary figures who have left an indelible mark on history - from Niccolo Machiavelli to Ayn Rand - are encountered.By the conclusion of lecture 36, you will have the context necessary to appreciate the evolution of a myriad of political ideas, including hot-button topics of today such as libertarianism, neoconservatism, feminism, and environmentalism.

    Consider the following:Although Judaism is defined by its worship of one God, it was not always a pure monotheism. In I Kings 8, King Solomon addresses the Lord by saying, "There is no God like You," suggesting that the Israelites recognized the existence of other gods.The practice of Judaism was focused on animal sacrifice until the destruction of the Second Temple by the Romans in the 1st century, which forced a radically new approach to worship.The political emancipation of the Jews in 18th-century Europe transformed a 1,000-year-old style of Jewish life. "You can’t find an expression of Judaism today that is just like [the way] Jews lived 300 years ago," says Professor Shai Cherry.Yet for all it has changed, Judaism has maintained unbroken ties to a foundation text, an ethnicity, a set of rituals and holidays, and a land.A Journey of Religious DiscoveryIn these 24 lectures, Professor Cherry explores the rich religious heritage of Judaism from biblical times to today.He introduces you to the written Torah, and you learn about the oral Torah, called the Mishnah (which was also later written down), and its commentary, the Gemara. And you discover how the Mishnah and Gemara comprise the Talmud, and how they differ from another form of commentary called Midrash.He teaches you about the three pillars of the world defined more than 2,000 years ago by Shimon the Righteous: Torah, worship, and deeds of loving kindness.He takes you through the calendar of Jewish holidays, from the most important, the Sabbath, to the key holidays of Rosh Hashanah, Yom Kippur, Passover, and Pentecost (Shavuot); and to historically minor celebrations such as Channukah, which is now a more visible holiday.You also learn about the origins and attributes of the different Jewish movements that formed in the wake of Emancipation in the late 1700s and the resulting full emergence of Judaism into Western society. These include the Reform, Conservative, Modern Orthodox, and Reconstructionist movements."Although Jewish history is not one long tale of travails," says Professor Cherry, "there have been several catastrophes that powerfully shaped the Jewish consciousness." He includes discussions of the impact on Jewish thought of the Babylonian exile and the destruction of the Second Temple in antiquity, and the Holocaust in the 20th century."We will see that for every topic that we cover we have a multiplicity of responses and a multiplicity of answers," says Professor Cherry, noting that this course could just as easily be called "An Introduction to Judaisms."What’s in a Name?Judaism’s sacred text is the Bible, also called the TaNaKH, the Torah, the Hebrew Bible, and, by Christians, the Old Testament. As Professor Cherry points out, these terms have different implications:TaNaKH: This is the Hebrew acronym for the three sections of the Bible—the Torah (the first five books, known as the Pentateuch), Nevi’im (Prophets), and Ketuvim (Writings).Torah: The word torah means "a teaching," and it can refer to the Pentateuch, the entire TaNaKH, or even the whole corpus of Jewish thought.Hebrew Bible: This is a religiously neutral term used by scholars for the TaNaKH. Professor Cherry notes that his expertise is in the TaNaKH, not the Hebrew Bible, since he approaches the text from the Jewish interpretive tradition.Old Testament: Christians refer to the TaNaKH as the Old Testament, since in their eyes it has been superseded by the New Testament. For Catholics, the Old Testament has a number of books that are not included in the TaNaKH.Interpreting the ScripturesJews and Christians not only have different names for the Bible, they understand it very differently. For example, Christianity takes an episode that is relatively minor in Jewish tradition—the temptation of Adam and Eve—and extracts from it the doctrine of original sin.Similarly, early rabbis took the repeated phrase, "And there was evening and there was morning," in the enumeration of the six days of creation and concluded that the day begins in the evening, which is why Jews start the celebration of their holidays at sundown.As a case study in interpretation, Professor Cherry delves deeply into the prohibition against seething (boiling) a kid in its mother’s milk, mentioned in Exodus and Deuteronomy, which led to the kosher practice of strict separation of meat and milk products. Recently, a scholar pointed out that the original Hebrew could be interpreted to mean fat instead of milk.A prohibition against seething a kid in its mother’s fat makes more sense, because it is another way of saying that the mother and offspring should not be slaughtered on the same day, in accord with the biblical injunction against killing two generations of the same species on the same day.But the rabbis had very good reasons to read the passage as they did, says Professor Cherry, who shows the theological logic that has resulted in the dietary separation of meat and milk, a practice observed by traditional Jews today.Unlocking Mysteries of Jewish Thought and Ritual"Let’s unpack this," Professor Cherry says often during these lectures, as he takes a concept, a biblical passage, or an episode from history and explores its meaning in Jewish thought and ritual.In doing so, he is following the footsteps of the acknowledged master of this form of analysis, the medieval Jewish philosopher Moses Maimonides, who figures prominently throughout the course and is treated in depth in Lecture 14.There, Professor Cherry focuses on Maimonides’s Guide of the Perplexed and its discussion of creation, prayer, and the reasons for the commandments. Maimonides is filled with insights into how Judaism evolved as it did, noting, for example, that the practice of ritual animal sacrifice in early Judaism was God’s way of taking a pagan rite that the Israelites had learned from the Egyptians and redirecting it.In a subsequent lecture, Professor Cherry shows how Maimonides’s success at putting Judaism on a logical footing set the stage for a reaction that produced the Jewish mystical system called the Kabbalah.Professor Cherry unlocks other mysteries, such as why the first day of the seventh month (Tishrei) is the Jewish New Year (Rosh Hashanah). It seems likely, he says, that "this was the time of the Babylonian New Year. So when the Jews were exiled to Babylonia, they saw that the Babylonians celebrated their New Year on that day, and said, ‘We’ve got some sacred occasion where we blow the trumpets, so let’s make that our New Year, too.’"He also explores different concepts of the Messiah, profiling two controversial candidates. The first is Shabbatai Tzvi, who was proclaimed Messiah by followers in 1665, and whose travels across Eastern Europe eventually landed him in Turkey, where he converted to Islam to avoid execution by the authorities.The other candidate is Rebbe Menachem Mendel Scheersohn, a charismatic leader of the Lubavitch Chassidim in Brooklyn, who died in 1994. Rebbe Scheersohn’s widely touted messianic credentials created intense debate and division in the Ultra-Orthodox community.From the Decalogue to Fiddler on the RoofFrom the first lecture on the Torah to the last on the Jews as the Chosen People, this course is packed with fascinating information, including:Jews use the term Decalogue, instead of Ten Commandments because there are actually more than 10 commandments in the Decalogue. For instance, "On six days you shall work and the seventh day shall be a Sabbath to you." Usually that counts as one: that you should have a Sabbath on the seventh day. But there is also, "On six days you shall work."The prophets in the biblical period served the same function as today’s free press. They tell the king what he doesn’t want to hear.When people die in the TaNaKH, everyone goes to the same place, Sheol—a shadowy underworld that is neither heaven nor hell.After crushing the Bar Kochvah revolt of the Jews in the 2nd century, the Romans changed the name of the land of Israel and Judaea to echo the Israelites’ ancient enemies, the Philistines. This is how the region came to be called Palestine.Today, the designation "Temple" on a Jewish house of worship is usually a sign that it is a Reform congregation because Reform Jews no longer look toward the dream of rebuilding the Jerusalem Temple.Orthodox Judaism is just as much a product of modernity as is Reform because several varieties of Orthodoxy emerged in the 19th century as a response to Emancipation, the Enlightenment, and the founding of the Reform movement.In addition, Professor Cherry devotes several lectures to complex issues such as the problem of evil and suffering, the Zionist movement, the place of women in the Jewish world, and how Judaism understands Christianity.Throughout, Professor Cherry is articulate, engaging, and passionate, with a gift for making a point by means of a memorable cultural reference. He calls attention to an echo of Jewish mystic Rav Kook in a Joni Mitchell song; to the Kabbalistic nature of "the force" and "the dark side" in George Lucas’s Star Wars; and to the Sabbath lesson given by Gene Wilder as an Old West rabbi in The Frisco Kid, when he dutifully dismounts his horse at sundown, risking capture by bandits.Professor Cherry notes that when he teaches introductory Judaism at Vanderbilt University, he asks his students to see two films: Fiddler on the Roof, for its picture of the breakdown of tradition as Jews confront modernity; and Woody Allen’s Crimes and Misdemeanors, for its treatment of secular Jews grappling with contemporary issues of faith and ethics. Both films repay viewing in light of the lessons you’ll learn in this course.In his final lecture, Professor Cherry sums up: "The Judaisms we’ve examined in this course reflect the ongoing struggles of the Jewish people from their ancient life as a sovereign nation, to the travails of exile, to the opportunities of acculturation in modernity, and finally to the re-establishment of the state of Israel. Hearing God’s words anew—receiving Torah every day—has meant reinterpreting the tradition, creatively rereading the words of the past, whether they relate to core ideas like the notion of evil and the notion of the Chosen People, or mitzvot such as the prohibition of idolatry, or the laws of marriage and divorce. Even the basis for reinterpreting the tradition, the claim that God’s words do not cease, is itself a rereading of Torah."

    These 24 thought-provoking lectures offer you the chance to reflect on some of the most powerful moral issues we face in our daily lives: Is it ever OK to lie? What are our moral obligations to others? What is the key to living the good life? From Plato to Kant to Bonhoeffer, you'll see how some of the world's greatest thinkers from across the ages have approached similar problems. Professor Martin provides a complete picture of various ethical schools and approaches and applies this rich philosophical overview to "case studies" relevant to our contemporary lives. You'll explore all the ins and outs of issues such as business ethics, love and marriage, privacy and technology, genetic engineering, animal rights, and much more. Engaging stories and thought experiments bring these issues to life, showing what different philosophical theories have to say about real-world ethical dilemmas. According to Professor Martin, the trick is to understand that the mind is like a parachute; it only works when it's open. Rather than take a side in any particular debate, this course provides a framework for thinking through a host of debates and dilemmas from all sides. Through it all, Professor Martin is a sympathetic guide, helping you think through some of our most complex decisions.

    Lowly born, he rose to prominence as he spread his vision of the redemption of the world. He attracted the attention of faithful disciples and suspicious local authorities. Eventually, he was tried, convicted, and executed.Today, his story is known the world over. And yet, more than two millennia later, great thinkers and everyday people still struggle to answer a single question: Who is Jesus? * Was he a wise sage who culled powerful teachings from centuries of Jewish tradition to create a new world vision of peace and love? * Or was he indeed God himself, the embodiment of divinity on earth, sent to bring salvation and redemption from sin? * Did his promise of salvation apply to all humankind or was it limited to only a few followers? And how could one participate in that promise?Since the earliest days of the faith, questions like these have been at the heart of Christianity. Over the centuries, they have led to fierce debate and produced deep divisions among the faithful. These questions have driven profound acts of faith and worship and incited war and persecution. They have contributed to the building of nations and the shaping of lives and have deeply influenced some of the greatest thinkers of Western philosophy. To ponder questions like these is to understand the very shape of the Western world and to comprehend the remarkable power Christian faith has in the life of believers.Now, in The History of Christian Theology, you have an opportunity to explore these profound questions and the many responses believers, scholars, and theologians have developed over more than 2,000 years. Through this 36-lecture course, award-winning Professor Phillip Cary of Eastern University reveals the enduring power of the Christian tradition—as both an intellectual discipline and a spiritual path.Through this course, you will gain thought-provoking insights into a set of teachings that changed the world and discover how, by learning about the diverse beliefs and practices within the wider Christian community, you can enrich your own experience of this great faith.
