Crisis of the House Divided is the standard historiography of the Lincoln-Douglas debates. Harry Jaffa provides the definitive analysis of the political principles that guided Lincoln from his re-entry into politics in 1854 through his Senate campaign against Douglas in 1858."Crisis of the House Divided has shaped the thought of a generation of Abraham Lincoln and Civil War scholars."--Mark E. Needly, Jr., Civil War History"An important book about one of the great episodes in the history of the sectional controversy. It breaks new ground and opens a new view of Lincoln's significance as a political thinker."--T. Harry Williams, Annals of the American Academy of Political and Social Sciences"A searching and provocative analysis of the issues confronted and the ideas expounded in the great debates. . . . A book which displays such learning and insight that it cannot fail to excite the admiration even of scholars who disagree with its major arguments and conclusions."--D. E. Fehrenbacher, American Historical Review
