Samuel Huntington, RIP
In 2004, National Review's Rich Lowry called Samuel Huntington, who died on December 24, "the most important political scientist in America." His New York Times obit is here.
Foreign Affairs has posted a selection of Huntington's essays here, including one of his most influential, written in 1993 and entitled "The Clash of Civilizations?. It's definitely worth a read or a re-read. ("The Lonely Superpower" is also worth your time.)
