1493: Uncovering the New World Columbus Created

By Charles C. Mann

I’m a big fan of Charles Mann’s previous book 1491: New Revelations of the Americas Before Columbus, in which he provides a sweeping and provocative examination of North and South America prior to the arrival of Christopher Columbus. It’s exhaustively researched but so wonderfully written that it’s anything but exhausting to read. With his follow-up, 1493, Mann has taken it to a new, truly global level. Building on the groundbreaking work of Alfred Crosby (author of The Columbian Exchange and, I’m proud to say, a fellow Nantucketer), Mann has written nothing less than the story of our world: how a planet of what were once several autonomous continents is quickly becoming a single, “globalized” entity.

Mann not only talked to countless scientists and researchers; he visited the places he writes about, and as a consequence, the book has a marvelously wide-ranging yet personal feel as we follow Mann from one far-flung corner of the world to the next. And always, the prose is masterful. In telling the improbable story of how Spanish and Chinese cultures collided in the Philippines in the sixteenth century, he takes us to the island of Mindoro whose “southern coast consists of a number of small bays, one next to another like tooth marks in an apple.” We learn how the spread of malaria, the potato, tobacco, guano, rubber plants, and sugar cane have disrupted and convulsed the planet and will continue to do so until we are finally living on one integrated or at least close-to-integrated Earth. Whether or not the human instigators of all this remarkable change will survive the process they helped to initiate more than five hundred years ago remains, Mann suggests in this monumental and revelatory book, an open question.

The Persistence of the Color Line

Racial Politics and the Obama Presidency

By Randall Kennedy

Among the best things about The Persistence of the Color Line is watching Mr. Kennedy hash through the positions about Mr. Obama staked out by black commentators on the left and right, from Stanley Crouch and Cornel West to Juan Williams and Tavis Smiley. He can be pointed. Noting the way Mr. Smiley consistently “voiced skepticism regarding whether blacks should back Obama” . . .

The finest chapter in The Persistence of the Color Line is so resonant, and so personal, it could nearly be the basis for a book of its own. That chapter is titled “Reverend Wright and My Father: Reflections on Blacks and Patriotism.”  Recalling some of the criticisms of America’s past made by Mr. Obama’s former pastor, Mr. Kennedy writes with feeling about his own father, who put each of his three of his children through Princeton but who “never forgave American society for its racist mistreatment of him and those whom he most loved.”  His father distrusted the police, who had frequently called him “boy,” and rejected patriotism. Mr. Kennedy’s father “relished Muhammad Ali’s quip that the Vietcong had never called him ‘nigger.’ ” The author places his father, and Mr. Wright, in sympathetic historical light.
