Avram Noam Chomsky is an American intellectual, philosopher, linguist, political activist, and social critic. Sometimes called "the father of modern linguistics", Chomsky is also a major figure in analytic philosophy and one of the founders of the field of cognitive science. He is a laureate professor of linguistics at the University of Arizona and an institute professor emeritus at the Massachusetts Institute of Technology (MIT). Among the most cited living authors, Chomsky has written more than 150 books on topics such as linguistics, war, and politics. In addition to his work in linguistics, since the 1960s, Chomsky has been an influential voice on the American Left as a consistent critic of the foreign policy of the United States, contemporary capitalism, and corporatocracy.

Because of his antireligious worldview, he is known as one of the "foremost atheists" of his time", although his worldview was closer to deism. However, in his defensive treatise Zajr al-Nabeh (The Repelling of the Barker)—a manuscript edited and published in 1965—al-Ma'arri explicitly identified himself as a faithful Muslim and systematically refuted the accusations of heresy leveled
