"Harry V. Jaffa illuminates Lincoln's understanding of the concepts of self-government, equality, and statesmanship, and he offers penetrating insights into Lincoln's refutation of the political philosophy and constitutional interpretations of John C. Calhoun and the southern secessionists. A New Birth of Freedom is a work of major importance that will require all Americans to reevaluate their understanding of Abraham Lincoln, especially his decision to prosecute the bloodiest war of American history."--BOOK JACKET.
