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

    (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.

    A retail store uses predictive data analytics to send pregnancy-related advertising to a teenager who has not told her parents about her condition. A police officer places a GPS device on a suspected criminal's car to follow him and build a case against him. The news is full of such stories, in which new technologies lead to dilemmas that could not have been imagined just a few decades ago. The 21st century has seen remarkable technological advances, with many wonderful benefits. But with these advances come new questions about privacy, security, civil liberties, and more. Big Data is here, which means that government and private industries are collecting massive amounts of information about each of us - information that may be used in marketing, to help solve criminal investigations, and to promote the interests of national security. Pandora's box has been opened, but in many ways the government is behind the times, relying on legislation from the 1970s to inform its stance on regulating the collection and use of this information. Taught by Professor Rosenzweig, JD, esteemed legal expert and professorial lecturer at The George Washington University School of Law, these 24 revealing lectures tackle the tough questions about surveillance and data in the 21st century. With Professor Rosenzweig's guidance, you'll scrutinize our system of oversight for intelligence agencies, and you'll consider the ways in which the information that is collected impacts (or potentially impacts) our civil liberties. This is your reliable source for all the facts you need to make your own reasonable choices - and take a first step toward an empowered future.

    

    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.

    Now, the exciting new field of "big history" allows us to explore human civilizations in ways unavailable to historians of previous generations. Big history scholars take a multidisciplinary approach to study great spans of time, unlocking important themes, trends, and developments across time and space.Unlike a traditional survey of history - with its focus on dates and events, kings and battles - The Big History of Civilizations is your chance to apply this cutting-edge historical approach to the epic story of humanity around the world. Taught by acclaimed Professor Craig G. Benjamin of Grand Valley State University, these 36 sweeping lectures trace the story of human civilizations from our emergence as a species, through the agricultural and industrial revolutions, and into the future.It only takes a few minutes of one lecture for you to discover that Big History is an amazing approach to history. Its grand vision will give you powerful new insights into human civilization, and it offers a profound analysis of some of our biggest questions: What makes us human? Where did we come from? And where are we going? There may be no easy answers, but Professor Benjamin takes you on a powerful journey to the limits of our understanding.What differentiates big history from any other field is the way it combines divergent fields, from archaeology and anthropology to ecology and philosophy, and ties them together, allowing you to see patterns of our past, present - and even future. From the just-right "Goldilocks factors" that allow civilizations to emerge to different ways civilizations have emerged across time and around the word, this riveting approach to history offers a multidisciplinary toolkit to tell the story about what makes us human.Listening Length: 17 hours and 49 minutes

    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.

    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.
