Michael Sandel is a renowned Harvard professor who teaches a class titled “Justice”. Its subject matter is ethical decisions and challenging students’ mental models. (ie: actually challenging people to think.) His class has been recorded in a high production value setting by WGBH in Boston and is now available online at http://justiceharvard.org/
It’s interesting and thought provoking material and the episodes come with suggested readings to go with them. I always appreciate excellent teaching and would encourage you to take a look at the site, even if you don’t have the time to watch all 12 episodes.
