For almost four decades, Eric Foner, one of America's most distinguished historians, has introduced readers of his journalism to unknown or forgotten characters in American history, methodically unearthing the hidden history of American radicalism. In this collection of polemical pieces, Foner expounds on the relevance of Abraham Lincoln's legacy in the age of Obama and on the need for another era of Reconstruction. In addition to articles in which Foner calls out politicians and the powerful for their abuse and misuse of American history. Foner assesses some of his fellow leading historians of the late 20th century, including Richard Hofstadter, Howard Zinn and Eric Hobsbawm. Foner ends with an open leter to Bernie Sanders analysing the great tradition of radicalism that he has spent his career studing and which, he argues, Americans of progressive disposition should seek to celebrate and retrieve.
