Patrick Porter at The Duck of Minerva argues that academic jealousy is the only reason Samuel Huntington gets criticized. We just wish we were more famous!
No, academics like to dismiss these works because the authors have appealed to a mass market, made meta-scale interpretations and predictions, and come as close to intellectual celebrity as possible for anyone who isn't Stephen Hawking or Albert Einstein. In an academic world that cherishes specialism and hair-splitting, that largely devotes its energy to internalised dialogues in exclusionary language, and which looks on fame and glory with envious suspicion, its no wonder that the mention of all three causes respectable scholars to roll their eyes.
He goes on to defend Huntington specifically. Maybe I am just showing my own jealousy, but I have read Clash of Civilizations and Who Are We? and the reason I don't like them is because you cannot read them in tandem and come to any conclusion but that Huntington ignores a lot of empirical evidence and is convinced that people of Latin American descent are inferior and ruining the United States. It is pure xenophobia.
