Noam Chomsky is a prolific author whose principal linguistic works after Syntactic Structures include Current Issues in Linguistic Theory (1964), The Sound Pattern of English (with Morris Halle, 1968), Language and Mind (1972), Studies on Semantics in Generative Grammar (1972), and Knowledge of Language (1986). In addition, he has wide-ranging political interests. He was an early and outspoken critic of U.S. involvement in the Vietnam War and has written extensively on many political issues from a generally left-wing point of view. Among his political writings are American Power and the New Mandarins (1969), Peace in the Middle East? (1974), Some Concepts and Consequences of the Theory of Government and Binding (1982), Manufacturing Consent (with E. S. Herman, 1988), Profit over People (1998), and Rogue States (2000). Chomsky’s controversial bestseller 9-11 (2002) is an analysis of the World Trade Center attack that, while denouncing the atrocity of the event, traces its origins to the actions and power of the United States, which he calls “a leading terrorist state.”
