This course will take you on an exciting adventure that covers more than 2500 years. Along the way, you’ll run into some very strange characters. For example, you’ll read about a man who hung out on street corners, barefoot and dirty, pestering everyone he met with questions. You’ll read about another man who climbed inside a stove to think about whether he existed. Despite their odd behavior, these and other philosophers of the Western world are among the most brilliant and influential thinkers of all time. As you read about them, you’ll see where many of the most fundamental ideas of Western civilization came from. You’ll also get a chance to ask yourself some of the same questions these great thinkers pondered. At the end, you’ll have a better understanding of yourself and the world around you, from atoms to outer space and everything in between.
