Arthur M. Schlesinger, Jr., is the preeminent American academic historian, despite not having a Ph.D. He made it to the top through the weight of his many outstanding volumes on American history, with the concentration on U.S. presidents, ranging from Andrew Jackson through Franklin Roosevelt to John F. Kennedy. Among academics, he is unique in his involvement in politics. He was a speechwriter for Adlai Stevenson and Kennedy, and an advisor in the Kennedy White House. He was and is a partisan. The major theme in his politics and writing has consistently been a defense of liberalism. It is his consistency, despite the ups and downs of liberalism over two centuries and despite its current unpopularity, that Stephen Depoe discusses in this brief monograph. Unfortunately, he has little to say on Schlesinger's foreign policy views.
