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.

    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.

    Kasser launches an ambitious and exciting inquiry into what makes science science, using the tools of philosophy to ask: * Why is science so successful? * Is there such a thing as the scientific method? * How do we distinguish science from pseudoscience? * Is science rational, cumulative, and progressive? Focusing his investigation on the vigorous debate over the nature of science that unfolded during the past 100 years, Professor Kasser covers important philosophers such as Karl Popper, W. V. Quine, Thomas Kuhn, Paul Feyerabend, Imre Lakatos, Carl Hempel, Nelson Goodman, and Bas van Fraassen.All of these thinkers responded in one way or another to logical positivism, the dominant movement influencing the philosophy of science during the first half of the 20 th century. Logical positivism attempted to ground science exclusively in what could be known through direct experience and logic.It sounds reasonable, but logical positivism proved to be riddled with serious problems, and its eventual demise is an object lesson in how truly difficult it is—perhaps impossible—to secure the logical foundations of a subject that seems so unassailably logical: science.

    And like it or not, it’s one of the most important things you do on a daily basis. Successful conversationshelp you advance professionally and make, maintain, and deepen relationships. Moreover, research shows that talking, when done on a substantive level, is correlated with a feeling of happiness and general well-being.Being a great conversationalist requires practice and effort. The good news is it’s a skill set anyone can acquire and refine. In just six lectures, How Conversation Works: 6 Lessons for Better Communication will teach you key strategies that can dramatically improve your ability to converse with anyone, from strangers to supervisors. Delivered by award-winning English professor Anne Curzan of the University of Michigan, this highly practical course focuses on the fundamental principles you need to know to become more conversationally aware and savvy at home, in the workplace, and beyond.You’ll be amazed by how much you can learn by stepping back from conversations and examining how they operate. You’ll notice things you never picked up on before—like what kind of speaker you are, the strategies you typically rely on (often without realizing it), and the subtleties of the strategies others may use when speaking with you. You’ll find yourself putting these lessons into practice to create more effective dialogues from the very first lecture.Choose Your Words WiselyAn expression like “shooting the breeze” makes conversation sound easy and free-flowing, but even low-stakes conversations have an underlying systematic structure that propels them along. This course examines that framework while showing you how the effective selection of words can help you forge connections and accomplish your objectives.Professor Curzan walks you through techniques for negotiating a variety of difficult situations, from proffering successful apologies to engaging in “face-threatening acts”—those uncomfortable moments that have the potential to do damage if your words aren’t chosen carefully.You’ll learn graceful ways of pointing out a mistake; asking someone to do something he or she doesn’t want to do; preparing a person for “no”; asking for a big favor; and providing information the recipient doesn’t want to hear.Conversations can only deepen connections when you pull your weight. In How Conversation Works, you’ll learn this involves knowing how to skillfully open and close an exchange, take turns speaking or “negotiate the conversational floor,” and send people subtle signals.Perhaps most important is sharing the burden to make discussions feel more mutual and enjoyable. These lectures arm you with numerous conversation-facilitating devices such as asking your fair share of questions and follow-up questions, which requires active listening; providing informative (but not overly informative!) answers to other people’s questions; introducing new topics for discussion and picking up on the topics of others; and telling good stories and helping good stories along.Talk Your Way to SuccessWhether you want to build rapport with colleagues, promote your accomplishments in an interview, give a winning presentation, ingratiate yourself with your boss, or even create a connection on a first date, knowing what to say and how to say it allows for more productive, smoother interactions. How Conversation Works helps you get ahead by outlining simple techniques for accomplishing all of this and more.Short vignettes featuring professional actors demonstrate what to do—and what not to do—in a variety of everyday scenarios such as striking up a conversation at a party. In video formats, green-screen technology places the professor in a range of environments as she provides concrete advice for taking an uncomfortable conversation in a new direction, making polite requests, mastering the “humble brag,” limiting your “talk time,” and monitoring your use of distracting discourse markers such as “um” and “you know.”In addition to sharing these out-the-door tips and techniques, Professor Curzan dispels common myths about conversation and presents enlightening research on how the conversational styles of men and women share much in common, despite differences in socialization; how you may be perceived for using direct speech or sentence fillers; how language-style matching quickly creates a sense of compatibility; how parents serve as conversational role models; and how e-communication has surprisingly systematic conventions.A Guide for the Real WorldAs a professor of English and linguistics and member of the American Dialect Society, Professor Curzan offers a refreshing yet scholarly take on the subject of conversation. Using a developmental and skills-based approach that gets right to the heart of the matter, her course provides tangible, actionable methods that can be worked into your conversational repertoire immediately. At first, the newfound awareness you’ll acquire from How Conversation Works may cause you to become self-conscious when you speak, but the act of “conversational noticing” will soon become second nature. Before long, you’ll realize you have the tools to make yourself clearly understood, put others at ease, rescue a conversation that’s gone wrong—and keep conversations from going off course in the first place.

    The issues Professor Dalton addresses in these lectures - and in Western political theory generally - fall into three sets of fundamental questions you'll get to unpack. The first set involves the essential characteristics of human nature and the good society. The second focuses on the intricate relationship between the individual and society. And the final set of questions involves theories about change.Through these lectures and their historical case studies, you'll be able to identify the fundamental questions and concerns that shape classical and modern political theory:Describe the influence of one's understanding of human nature upon one's vision of the good society.Compare and contrast the views of theorists regarding the purpose of the state, the relationship between politics and ethics, and the qualifications for exercising political power.Discuss views of leading political theorists regarding the meaning of freedom, the sources of legitimate political authority, and the obligations of individuals to the state or society, and more.

    (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.

    And while many of us look to make sense of Russia through its political history, in many ways a real grasp of this awe-inspiring country comes from looking closely at its cultural achievements. The 24 lectures of Understanding Russia: A Cultural History survey hundreds of years of Russian culture, from the world of Ivan the Terrible to the dawn of the Soviet Union to the post-war tensions of Putin's Russia. Blending history with cultural studies, they are designed to bring you closer than ever before to the Russian people - not just the authoritarian rulers like Peter the Great, the Romanovs, and Stalin but the everyday men and women who sought their own meaning in the poetry of Pushkin, the comfort of early folk tales, the faith of medieval iconography, the avant-garde films of Eisenstein, and more. You'll discover surprising insights into centuries of cultural history, including peasant superstitions, such as avoiding whistling indoors, and the culture of queuing for goods and services that defined everyday life for ordinary Soviets. You'll also spend time in the company of novelists, painters, poets, filmmakers, impresarios, composers, revolutionaries, and intellectuals who shaped Russia in myriad ways, including The Five, a group of composers who created a distinctly national sound based in part on Russian folk music; and Sergei Eisenstein, the filmmaker whose Battleship Potemkin revolutionized the language of cinema. In a time when the eyes of the Western world are constantly drawn to Russia, it's amazing how little we really know about its culture. These lectures will help you finally understand that complex, thrilling, and undeniably fascinating spirit.

    As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man." In fact, civilization itself began in the quest for food. Humanity's transition to agriculture was not only the greatest social revolution in history, but it directly produced the structures and institutions we call "civilization." In 36 fascinating lectures, award-winning Professor Albala puts this extraordinary subject on the table, taking you on an enthralling journey into the human relationship to food. With this innovative course, you'll travel the world discovering fascinating food lore and culture of all regions and eras - as an eye-opening lesson in history as well as a unique window on what we eat today.
