Irving Kristol (1920–2009), formerly senior fellow at the American Enterprise Institute, is the author of many books, including Neoconservatism: The Autobiography of an Idea (1999). He has served as editor or co-editor of several journals, notably Commentary (1947–1952) and Public Interest (1965–2005). Kristol is one of the founders of the neoconservative movement—or, as he prefers to say, “persuasion.” In the following essay, he outlines the tenets of this persuasion and explains how it differs from other varieties of conservatism.
