Conventional wisdom suggests there is a sharp distinction between emotion and reason. Emotions are seen as inferior, disruptive, primitive, and even bestial forces. These 24 remarkable lectures suggest otherwise-that emotions have intelligence and provide personal strategies that are vitally important to our everyday lives of perceiving, evaluating, appraising, understanding, and acting in the world.

Look beyond the abstract dates and figures, kings and queens, and battles and wars that make up so many historical accounts. Over the course of 48 richly detailed lectures, Professor Garland covers the breadth and depth of human history from the perspective of the so-called ordinary people, from its earliest beginnings through the Middle Ages.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

These 12 illuminating lectures paint a rich and detailed portrait of the life, works, and ideas of this remarkable figure, whose own search for God has profoundly shaped all of Western Christianity. You'll learn what Augustine taught and why he taught it – and how those teachings and doctrines helped shape the Roman Catholic Church. These lectures are rewarding even if you have no background at all in classical philosophy or Christian theology.

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

With this exciting and historically rich six-lecture course, experience for yourself the drama of this dynamic year in medieval history, centered on the landmark Norman Conquest. Taking you from the shores of Scandinavia and France to the battlefields of the English countryside, these lectures will plunge you into a world of fierce Viking warriors, powerful noble families, politically charged marriages, tense succession crises, epic military invasions, and much more.

While human history is usually studied from the perspective of a few hundred years, anthropologists consider deeper causes for the ways we act. Now, in these 12 engrossing lectures, you'll join an expert anthropologist as she opens an enormous window of understanding for you into the thrilling legacy left by our primate past. In these lectures, you'll investigate a wealth of intriguing, provocative questions about our past and our relationship to primates.

Imagine a world without bees, butterflies, and flowering plants. That was Earth 125 million years ago. Turn back the clock 400 million years, and there were no trees. At 450 million years in the past, even the earliest insects had not yet developed. And looking back 500 million years, the land was devoid of life, which at that time flourished in a profusion of strange forms in the oceans. These and other major turning points are the amazing story of evolution.

What is life? What is my place in it? What choices do these questions obligate me to make? More than a half-century after it burst upon the intellectual scene - with roots that extend to the mid-19th century - Existentialism's quest to answer these most fundamental questions of individual responsibility, morality, and personal freedom, life has continued to exert a profound attraction.

As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.

Every day of your life is spent surrounded by mysteries that involve what appear to be rather ordinary human behaviors. 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.

Whether complete or only fragmentary, the 930 extant Dead Sea Scrolls irrevocably altered how we look at and understand the foundations of faith and religious practice. Now you can get a comprehensive introduction to this unique series of archaeological documents, and to scholars' evolving understanding of their authorship and significance, with these 24 lectures. Learn what the scrolls are, what they contain, and how the insights they offered into religious and ancient history came into focus.

What can we still learn from C.S. Lewis? Find out in these 12 insightful lectures that cover the author's spiritual autobiography, novels, and his scholarly writings that reflect on pain and grief, love and friendship, prophecy and miracles, and education and mythology.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

The story of our world and the different living things that have populated it is an amazing epic with millions of species, exotic settings, planet-wide cataclysms, and surprising plot twists. These 36 lectures tell the all-embracing story of life on Earth - its origins, extinctions, and evolutions - in a manner that assumes no background in science. At half an hour per lecture, you’ll cover the entire 4.54-billion-year history of Earth in 18 hours, averaging 70,000 years per second!

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

Between 1861 and 1865, the clash of the greatest armies the Western hemisphere had ever seen turned small towns, little-known streams, and obscure meadows in the American countryside into names we will always remember. In those great battles, those streams ran red with blood-and the United States was truly born.

Great powers no longer fight great wars. But how exactly did countries like the United States go from confronting powerful adversaries in 1914 and 1939 Europe to waging lengthy counterinsurgency campaigns in places like Iraq and Afghanistan? The answer lies in the profound geopolitical and technological changes that came in between.

In these 24 lectures, The Great Courses teams up with the Smithsonian’s National Zoo and Conservation Biology Institute, to take you behind the scenes of the animal world. Dr. Moore has crafted a wonderful introduction to zoology that brings you up close and personal with a breathtaking variety of animal species through the eyes of a trained zoologist.
