The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    Indeed, it may be the biggest question of all - at once profound and universal, but also deeply personal. We want to understand the world in which we live, but we also want to understand how to make our own lives as meaningful as possible; to know not only why we're living, but that we're doing it with intention, purpose, and ethical commitment. But how, exactly, do we find that meaning, and develop that commitment? How can we grasp why we are here? Or how we should proceed? And to whom, exactly, we should listen as we shape the path we will walk? This comprehensive 36-lecture series from a much-honored scholar is an invigorating way to begin or continue your pursuit of these questions, and it requires no previous background in philosophical or religious thought. It offers a rigorous and wide-ranging exploration of what various spiritual, religious, and philosophical traditions from both the East and West have contributed to this profound line of questioning, sharing insights from sources that include ancient Indian texts, such as: The Bhagavad-Gita Foundational Chinese texts like the Daodejing and the Chuang Tzu Classical Western texts, such as Aristotle's Nichomachean Ethics and Marcus Aurelius's Meditations Modern philosophers and writers like David Hume, Immanuel Kant, Friedrich Nietzsche, and Leo Tolstoy the unique perspectives offered by Native Americans, in this case, the Lakota Sioux medicine man and writer, John Lame Deer More recent and contemporary philosophers, such as Mohandas Gandhi and the Dalai Lama

    In Homo Deus, he looked to our future. Now, one of the most innovative thinkers on the planet turns to the present to make sense of today's most pressing issues.How do computers and robots change the meaning of being human? How do we deal with the epidemic of fake news? Are nations and religions still relevant? What should we teach our children?Yuval Noah Harari's 21 Lessons for the 21st Century is a probing and visionary investigation into today's most urgent issues as we move into the uncharted territory of the future. As technology advances faster than our understanding of it, hacking becomes a tactic of war, and the world feels more polarized than ever, Harari addresses the challenge of navigating life in the face of constant and disorienting change and raises the important questions we need to ask ourselves in order to survive.In twenty-one accessible chapters that are both provocative and profound, Harari builds on the ideas explored in his previous books, untangling political, technological, social, and existential issues and offering advice on how to prepare for a very different future from the world we now live in: How can we retain freedom of choice when Big Data is watching us? What will the future workforce look like, and how should we ready ourselves for it? How should we deal with the threat of terrorism? Why is liberal democracy in crisis?Harari's unique ability to make sense of where we have come from and where we are going has captured the imaginations of millions of readers. Here he invites us to consider values, meaning, and personal engagement in a world full of noise and uncertainty. When we are deluged with irrelevant information, clarity is power. Presenting complex contemporary challenges clearly and accessibly, 21 Lessons for the 21st Century is essential reading.

    When Walter Kaufmann wrote it in the immediate aftermath of World War II, most scholars outside Germany viewed Nietzsche as part madman, part proto-Nazi, and almost wholly unphilosophical. Kaufmann rehabilitated Nietzsche nearly single-handedly, presenting his works as one of the great achievements of Western philosophy.Responding to the powerful myths and countermyths that had sprung up around Nietzsche, Kaufmann offered a patient, evenhanded account of his life and works, and of the uses and abuses to which subsequent generations had put his ideas. Without ignoring or downplaying the ugliness of many of Nietzsche's proclamations, he set them in the context of his work as a whole and of the counterexamples yielded by a responsible reading of his books. More positively, he presented Nietzsche's ideas about power as one of the great accomplishments of modern philosophy, arguing that his conception of the will to power was not a crude apology for ruthless self-assertion but must be linked to Nietzsche's equally profound ideas about sublimation. He also presented Nietzsche as a pioneer of modern psychology and argued that a key to understanding his overall philosophy is to see it as a reaction against Christianity.Many scholars in the past half century have taken issue with some of Kaufmann's interpretations, but the book ranks as one of the most influential accounts ever written of any major Western thinker.

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

    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.

    And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of approaching and grappling with some of the universe's most pressing and vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered? What are some of the next avenues of exploration for today's chemists, physicists, biologists, and astronomers? Pondering the answers to these and other questions is a great way to appreciate the grandeur and complexity of the world around you, better understand and discuss news and developments in science, and spark further interest in some of science's many exciting areas of study. "We know a lot about the universe. But there's even more that we don't know,"says astrophysicist and Professor Neil deGrasse Tyson, director of the Hayden Planetarium, an award-winning lecturer, and one of the world's foremost experts on the secrets of the universe. And his course The Inexplicable Universe: Unsolved Mysteries is the perfect gateway into this mind-bending and eye-opening subject. Each of these six self-contained lectures is a marvelous journey to the frontiers of the known (and unknown) universe and introduces you to tantalizing questions being addressed by the world's top scientists. Undeniably engaging and fascinating, this lecture series is a wonderful entrée to scientific pursuits that lie at the very heart of the history and nature of our universe. An Informed Scientific Conversation Central to The Inexplicable Universe is the way it takes you deep into hidden layers of the universe in a manner that is extremely accessible. Rather than a stern lecture given before a podium complete with confusing mathematics, Professor Tyson's lectures have the feel of an informed conversation that manages to be both thorough and easy to grasp. With each of the inexplicable mysteries he lays bare for you, Professor Tyson introduces you to the history behind it, lays out the science that has helped us grasp it, explains what researchers have discovered to date, and reveals what we have yet to discover. And while the topics explore subjects in everything from quantum mechanics to cosmology to string theory, you'll never feel overwhelmed by what you're learning. In fact, you're more likely to find yourself intrigued by just how much we know-and curious about what the near future will possibly reveal. Explore Fascinating Territory So what territory will you chart in this course? Here are some of the inexplicable ideas you'll investigate in these lectures. Neutrinos: Discovered in 1956, these fast-moving, ghostlike particles are made in abundance in the sun's core. They hardly interact with matter; it takes a light-year's worth of lead (5.8 trillion miles) to stop a neutrino. Not only that, but 65 billion neutrinos pass through every centimeter of your body that's facing the sun every second of every day. String theory: This astounding theory offers the hope of unifying all the particles and forces of physics. In the past several decades since the dawn of string theory, it's been imagined that all the fundamental particles we see and measure are just the manifestation in our dimension of strings vibrating in higher dimensions and at different frequencies. Quantum foam: This idea posits that when the fabric of space and time is so tightly curved on itself, space-time is less a smooth curve and more like the froth on a latte. In this state of matter and energy, quantum fluctuations can spawn entire universes, each with slightly different laws of physics within them! In addition, you'll also get a peek at what it would be like to travel through a black hole, ponder the possibility that life on Earth originated in debris from Mars, probe the supposed existence of multiple universes, and even imagine the possible end of the universe itself. A One-on-One Chat with a Renowned Science Educator Professor Tyson is renowned throughout the scientific community and the media for his vast knowledge, his penetrating insights, and his amazing ability to make even the most intimidating areas of science accessible, engaging, and-most of all-enjoyable. He brings the same inviting tone and sharp intellect to The Inexplicable Universe as he does to his range of media appearances on popular television programs. Due to its unique subject matter The Inexplicable Universe takes a highly visual approach. Many of the fascinating subjects in the course, such as black holes, string theory, and multiple universes are best demonstrated visually and Professor Tyson's lectures feature expertly crafted computer animations, explanatory diagrams, high resolution photographs, and other instructive visual elements. In order to better explain to you some of the grand, intricate ideas being discussed, Professor Tyson personally interacts with many of these animations and graphics using greenscreen technology. Please note that, due to the highly visual nature of The Inexplicable Universe, the course does not come with a guidebook. We did not believe a simple book could adequately convey the information in the course, and rather than make a guidebook that did not do the course justice, we decided to not offer one. However, we believe that you will be very excited by how we produced this course and will find it to be an enriching and fulfilling experience in your educational journey.

    Central to many spiritual and philosophical traditions and known in English as "meditation," these practices are considered a major means for enhanced awareness and self-mastery. In recent decades, modern science has dramatically confirmed what advanced meditators have long claimed—that meditation, correctly practiced, offers deep and lasting benefits for mental functioning and emotional health, as well as for physical health and well-being.

    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.

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

    And of a nation that fought a Civil War that freed its slaves, and outlawed segregation and discrimination.This is history shaped by Revolutionary War and Vietnam, Thomas Jefferson and William Jefferson Clinton, Puritanism and Feminism, Booker T. Washington and Martin Luther King, Jamestown and Disneyland, Harpers Ferry and Henry Ford, oil wells and Orson Welles.This is a review of the extraordinary blend of people, ideas, inventions, and events that comprise The History of the United States. In this seven-part, 84-lecture series, three noted historians and lecturers—two of whom teach other popular Teaching Company courses—present the nation's past through their areas of special interest.

     His starting point is moral intuition—the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right. He blends his own research findings with those of anthropologists, historians, and other psychologists to draw a map of the moral domain. He then examines the origins of morality, overturning the view that evolution made us fundamentally selfish creatures. But rather than arguing that we are innately altruistic, he makes a more subtle claim—that we are fundamentally groupish. It is our groupishness, he explains, that leads to our greatest joys, our religious divisions, and our political affiliations. In a stunning final chapter on ideology and civility, Haidt shows what each side is right about, and why we need the insights of liberals, conservatives, and libertarians to flourish as a nation.
