Historian Richard Striner discusses his new book, "Summoned to Glory: The Audacious Life of Abraham Lincoln". Where previous Lincoln biographers describe his temperament as “moderate,” “passive,” or even “conservative,” historian Richard Striner offers an original perspective that will shed new light on one of the most studied figures in American history. By emphasizing the workings of Lincoln’s mind—stressing his cunning, his overall honesty, strategic thinking—even his ability to change his mind—Striner looks anew at many topics and themes important to Lincoln’s story that either revise or add new meaning to the work of previous biographers.
