Michael J. Sandel teaches political philosophy at Harvard University. His books What Money Can't Buy- The Moral Limits of Markets, and Justice- What's the Right Thing to Do? were international best sellers and have been translated into 27 languages. Sandel's legendary course 'Justice' was the first Harvard course to be made freely available online and on television and has been viewed by tens of millions of people. His BBC series 'The Global Philosopher' explores the philosophical ideas lying behind the headlines with participants from around the world. Sandel has been a visiting professor at the Sorbonne, delivered the Tanner Lectures on Human Values at Oxford, the Reith Lectures for the BBC, and is a member of the American Academy of Arts and Sciences. His lecture tours have taken him across five continents and packed such venues as St. Paul's Cathedral (London), the Sydney Opera House (Australia), and an outdoor stadium in Seoul (S. Korea), where 14,000 people came to hear him speak.
