At the end of October at the Clinton Presidential Center in Little Rock, Ark., Slate hosted the Slate 60 Conference on Innovative Philanthropy with our co-sponsors, the William J. Clinton Foundation and the University of Arkansas Clinton School of Public Service. The conference featured philanthropists like Michael Milken, Jean Case, Michael J. Fox and Carlos Slim, and public figures like Bill Clinton and Eliot Spitzer. From an array of speeches and panels, we've put together a few choice excerpts for you.
