A quick heads up: The BBC is featuring a series of lectures with Michael Sandel (Harvard Professor of Government) that will collectively talk about "the prospects of a new politics of the common good." Sandel is a very popular professor at Harvard. Some 15,000 students have taken his courses over 30 years. In the first lecture, Sandel takes a look at the morality of the markets (a timely topic, to be sure) and "considers the expansion of markets and how we determine their moral limits." You can listen here.
Also, note that you can find another mini-course by Sandel on the Harvard website. Justice: A Journey in Moral Reasoning (Video) is one of the very few courses that Harvard has produced and made available to the public. You can find it otherwise listed in our collection of Free University Courses.
