Fresh Air on Four Corners

The revelations about secret National Security Agency programs, leaked by Edward Snowden earlier this month, have stirred great controversy, but this type of surveillance is not entirely new, according to journalist Shane Harris.

In his 2010 book, The Watchers: The Rise of America's Surveillance State, Harris traced the evolution of these surveillance programs in the U.S.

The sculptor Claes Oldenburg was born in Stockholm but grew up in Chicago, went to Yale and came to New York in 1956, where he became a key player in the pop art movement — the major counter-reaction to the abstract expressionism that dominated the 1950s. So much for art history.

Although Oldenburg is a serious artist, probably no artist in history ever created works that were more fun. In a new show at the Museum of Modern Art — really two shows — practically everyone, including myself, was walking through the galleries with a huge grin.

Here we go into the wild blue yonder again with Colum McCann. In his 2009 novel, Let the Great World Spin, McCann swooped readers up into the air with the French aerialist Philippe Petit, who staged an illegal high-wire stunt walk between the twin towers of the World Trade Center in 1974. Strictly speaking, Let the Great World Spin was not a Sept. 11 novel, and yet almost everyone rightly read it as one, since McCann's tale commemorated the towers at the literal zenith of their history.
