The signage of segregation, terrible and tangible, left us with a deficient vision of Jim Crow America. The cruelty of a whites only placard may seem like the bookend to Bull Connor’s gross brutality, but such signage implied that the dangers and humiliations of Jim Crow always came labeled. White supremacy drew its power from the ritualized humiliation of black people having to ask if a public service was available. Even sundown towns—communities across the nation that violently banned African Americans after dark—didn’t always advertise their own rules. For mid-twentieth-century black Americans,

“Are we going to burn it?” A question about the fate of the future concludes Hazel Carby’s Race Men (1998), a powerful academic book about suffocating representations of black American masculinities based on a lecture the author delivered at Harvard. In her newest book, Carby is already burnt, the result of a smoldered past. “Imperial Intimacies is a very British story,” she writes in the preface. It is also her story: about growing up after World War II, about her childhood in the area now known as South London, about the family histories of her white Welsh mother and black Jamaican father,

In 2009 Mohamed Nasheed, the president of the Maldives, the island nation sinking into the sea, put on a wet suit and an air tank and, along with several of his ministers, held a cabinet meeting underwater. Nasheed hoped to give the world a sense of its collective future. At an event at Columbia Law School he later said: “You can drastically reduce your greenhouse gas emissions so that the seas do not rise so much. Or when we show up on your shores in our boats, you can let us in. Or when we show up on your shores in our boats, you can shoot us. You pick.”

The rest of the world has long warned

Something is happening out there in the dark fields of “the discourse.” Incoherence is now a virtue. Rather than irony, modesty, discernment, ambivalence, or the mental sprightliness needed to parse conflicting views, a proud refusal to make solid arguments may be the cure for our divided times. Incoherence strikes a blow to partisan bickering and campus groupthink. Incoherence recoils from “tribes.” If an opinion sounds half-baked, or a claim brashly obtuse, it’s simply plowing through your pieties and wrenching open your padlocked mind. Incoherence is courage, incoherence is pluralism,

All four of Nicholas Lemann’s major books examine crucial episodes of American history through the prism of lives that shaped or were shaped by that history. In 1991’s The Promised Land, Mississippians Ruby Lee Daniels and George Hicks embody the Great Migration as they relocate to Chicago. In 1999’s The Big Test, the Educational Testing Service’s Henry Chauncey and Los Angeles attorney Molly Munger carry Lemann’s analysis of an SAT-fueled meritocracy more privileged than it knows. Redemption’s alarming and often brutal 2006 account of racist terrorists destroying Reconstruction makes flawed

In the dark of the night of July 19, AD 64, a fire broke out in the slums of Rome and, swept along by vicious winds, devastated the town, leveling several districts entirely. The fire burned for six days, died down, was reignited, and burned for three more. Hundreds of people were killed; many more were left destitute and homeless.

In the midst of it all, the famously conniving Emperor Nero—who was away in his holiday home on a cool hillside when the fires began—was reported by the historian Tacitus to have placidly watched the city burn as he nonchalantly played his fiddle or plucked his
