Perhaps the most influential science book ever written, On the Origin of Species has continued to fascinate for more than a century after its initial publication.

Humanism is an expansive tradition of thought that places shared humanity, cultural vibrancy, and moral responsibility at the center of our lives. For centuries, this worldview has inspired people to make their choices by principles of freethinking, intellectual inquiry, fellow feeling, and optimism.

Yet Hume's philosophy is grounded in an honest assessment of nature - human nature in particular. The Great Guide is an engaging and eye-opening account of how Hume's thought should serve as the basis for a complete approach to life. Julian Baggini masterfully interweaves biography with intellectual history and philosophy to give us a complete vision of Hume's guide to life.
