In the latest of his many books on Lincoln, Allen C. Guelzo argues that the "redeemer president" is himself in need of redemption-redemption from a contemporary mindset that refuses to acknowledge moral indebtedness. Challenging various falsifications of the past, from the neo-abolitionist claim of "self emancipation" to simplistic accounts of the postwar failure of emancipation, Guelzo offers a richly textured and fearless brief for Lincoln's crucial role in emancipation.
