2009 Reith Lecturer Michael Sandel profiled by Jonathan Derbyshire in The New Statesman. This article gives an excellent introduction to Sandel's philosophical background and how it informs his lecture series on 'A New Citizenship'. Sandel, in his role as a public philosopher advocates clarity and a desire to stimulate public debate. Derbyshire is sympathetic to Sandel's view that we have sacrificed too much of the public good on the altar of economics.
If you want to find out more about Sandel's ideas, the best place to start (at least until his book Justice is published) is Public Philosophy: Essays on Morality in Politics
Photograph shows Michael Sandel interviewed for the Philosophy Bites podcast shortly before he gave his first 2009 Reith Lecture. David Edmonds, the other half of Philosophy Bites, (also co-author with John Eidnow of Wittgenstein's Poker, Rousseau's Dog, and Bobby Fisher Goes to War) is holding the microphone, and I'm on the right looking a bit stiff.
