I talk with historian DAVID KAISER about two books. His own A LIFE IN HISTORY suggests that as fields like African-American History and Women’s History emerged to deal with evidence nobody had bothered to look at before, we’ve tended to look less at our roots in European politics and diplomacy or at history’s broader sweep. Might this increase our tendency to repeat the past? THE FOURTH TURNING: An American Prophesy (Straus & Howe) holds that history is not linear, but cyclical, and that every 80 years or so, a crisis disrupts society, the old order crumbles, and a new order emerges. No surprise - we’re in the midst of such a crisis. Do we emerge broken or renewed?
