Shelby Steele is the author of two bestselling books on race: The Content of Our Character: A New Vision of Race in America, and A Dream Deferred: The Second Betrayal of Black Freedom in America.
In this article from the Wall Street Journal (1999) he explains the incredible dream and legacy of Martin Luther King, Jr., and why it sadly remains unfulfilled today.
A couple of other articles of interest--both from the Wall Street Journal--is Steele's analysis of the legacy of W.E.B. DuBois, as well as his take on the failure of moral imagination and the fallout from the Trent Lott controversy.
