No subject is bigger than reality itself, and nothing is more challenging to understand, since what counts as reality is undergoing continual revision and has been for centuries. The quest to pin down what's real and what's illusory is both philosophical and scientific, a metaphysical search for ultimate reality that goes back to the ancient Greeks. For the last 400 years, this search has been increasingly guided by scientists, who create theories and test them in order to define and redefine reality.

Professor Hall helps you cut through deception and faulty reasoning in these 24 humorous, clear, and interesting lectures, offering a friendly but intellectually rigorous approach to the problem of thinking.

Who was Friedrich Nietzsche? This lonely and chronically ill, yet passionate, daring, and complex man is perhaps the most mysterious and least understood of all contemporary philosophers.

The quest to understand the mind has motivated some of history's most profound thinkers. But only in our own time are we beginning to see the true complexity of this quest, as today's philosophers draw on the latest evidence from neuroscience, psychology, artificial intelligence, linguistics, and other fields to probe deeply into the inner workings of the mind.

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.
