Rawls is not easy to understand. This is largely because of how Rawls presents his ideas, though this difficulty creates opportunities for debate within political philosophy.
Below is a lecture by Harvard Government Professor Michael Sandel on Rawls and issues of wealth, inequality, and distributive justice. While I disagree with much of Sandel’s academic criticism of Rawls, I think that he does an excellent job in this lecture and in his recent books looking to present the concept of justice to a broader audience. In particular, I like how he presents a number of key points in Rawlsian thinking, though this is still just an introduction.Enjoy.
