Noam Chomsky

• 1. Introduction

  ›

  Noam Chomsky wrote his first article at the age of 10, absorbed by the fall of Barcelona and the destruction of the Spanish anarchosyndicalist movement. That detail carries a kind of compressed prophecy: here was a child in Philadelphia, reading his way into political fury long before he had any forum to express it. Decades later, he would be placed on President Richard Nixon's list of political opponents, arrested outside the Pentagon, and cited within the Arts and Humanities Citation Index more often than any other living scholar from 1980 to 1992. He has written more than 150 books. He has been called both the father of modern linguistics and, by the German magazine Der Spiegel, the Ayatollah of anti-American hatred. No other intellectual of his era has attracted praise and denunciation on quite this scale. How did the son of immigrant Ashkenazi Jews become the most cited living author in the humanities? What does his theory of language actually claim? And what do we make of a man whose commitment to unconditional free speech led him into one of the most damaging controversies of his career?

• 2. A Philadelphia Childhood

  ›

  William Chomsky fled the Russian Empire in 1913, from territory that is now Ukraine, to escape conscription, and worked in Baltimore sweatshops before eventually becoming principal of the Congregation Mikveh Israel religious school in Philadelphia. William's guiding philosophy of education held that people should be well integrated, free and independent in their thinking, concerned about improving and enhancing the world. His son absorbed that mission deeply. Both parents spoke Yiddish as their first language, though it was considered taboo to speak it at home. His mother Elsie had emigrated from what is now Belarus and spoke a native New York City English dialect; his father spoke English with a foreign accent.

  Noam's only sibling, David Eli Chomsky, was born five years after Noam and later became a cardiologist in Philadelphia. The brothers were close, but David was the easygoing one. Noam, by family accounts, could be very competitive. He faced antisemitism as a child, especially from Philadelphia's Irish and German communities.

  He attended the independent, Deweyite Oak Lane Country Day School and Philadelphia's Central High School, where he excelled but found the hierarchical and domineering teaching methods deeply troubling. Relatives who worked in the International Ladies' Garment Workers' Union introduced him to socialism and far-left politics. An uncle in New York City ran a newspaper stand that served as an informal salon for Jewish leftists, and the young Chomsky devoured the political literature he found in the city's anarchist bookstores. He arrived at anarchism before any other leftist position, and he later described that as a lucky accident.

• 3. The Making of a Linguist

  ›

  In 1945, at 16, Chomsky enrolled at the University of Pennsylvania in a general program of study, drifting across philosophy, logic, and languages and developing a primary interest in Arabic. Frustrated enough to consider dropping out and moving to a kibbutz in Mandatory Palestine, his intellectual life was rescued by a meeting with the linguist Zellig Harris in a political circle in 1947. Harris steered Chomsky toward theoretical linguistics and supervised his BA honors thesis, a study of the morphophonology of modern Hebrew. Chomsky received his MA from Pennsylvania in 1951 for a revised version of that thesis.

  From 1951 to 1955, Chomsky held a place in the Society of Fellows at Harvard University, where he undertook the research that became his doctoral dissertation on transformational grammar. The philosopher Willard Van Orman Quine was a draw, as was J. L. Austin of Oxford, who was visiting at the time. Both strongly influenced him. In 1952, Chomsky published his first academic paper in The Journal of Symbolic Logic. By 1954 he was presenting his ideas at lectures at the University of Chicago and Yale University, bluntly critical of behaviorism. He submitted his doctoral thesis to Pennsylvania in 1955, earned his PhD, and that same year joined the faculty at MIT.

  Harvard professor George Armitage Miller read the thesis and was impressed enough to collaborate with Chomsky on several technical papers in mathematical linguistics. That collaboration proved consequential: Miller later became one of the architects of the cognitive science field that Chomsky's work helped call into existence.

• 4. The Grammar of the Mind

  ›

  Chomsky's core linguistic claim is that language is biologically preset in the human mind. Children are exposed to only a small, finite subset of possible sentences in their first language, yet they reliably acquire the ability to understand and produce an infinite number of sentences, including ones no one has ever spoken before. Chomsky called this gap the poverty of the stimulus, and he argued it could only be explained by an innate linguistic capacity built into the species.

  His 1957 book Syntactic Structures, which MIT promoted him to associate professor the same year it appeared, radically opposed the dominant Harris-Bloomfield tradition in the field. Responses ranged from indifference to hostility. The linguist John Lyons later wrote that it had revolutionized the scientific study of language. A Minnesota State University Moorhead poll eventually ranked Syntactic Structures as the single most important work in cognitive science.

  Chomsky developed transformational grammar in the mid-1950s. It held that surface sentence structures are derived from deeper underlying structures that more directly reflect meaning. That model evolved through government and binding theory in the 1980s and then into the minimalist program, which he initiated and which asks which minimal set of principles most elegantly explains human language. He also grouped possible phrase-structure grammar types into four nested subsets, a classification known as the Chomsky hierarchy, which became fundamental to theoretical computer science, compiler construction, and automata theory. ACM Turing Award winner Donald Knuth credited this work with helping him connect mathematics, linguistics, and computer science, and IBM's John Backus drew on Chomsky's concepts when developing FORTRAN.

  Not everyone accepted the theory. Michael Tomasello challenged the claim of innate syntactic knowledge as grounded in theory rather than behavioral observation. Geoffrey Pullum challenged the empirical basis of the poverty of the stimulus argument. More recently, researchers have shown that certain recurrent neural network architectures can learn hierarchical structure without any explicit innate constraint.

• 5. Dissent and Arrest

  ›

  Chomsky joined protests against U.S. involvement in the Vietnam War beginning in 1962, speaking at small gatherings in churches and homes. His 1967 essay in The New York Review of Books, "The Responsibility of Intellectuals", brought him national attention for the first time as a public dissident. That essay and other political articles were collected into his first political book, American Power and the New Mandarins, published in 1969.

  He refused to pay half his taxes. He publicly supported students who refused the draft. He was arrested while participating in an anti-war teach-in outside the Pentagon. He co-founded the anti-war collective RESIST with Hans Koning, Mitchell Goodman, Denise Levertov, William Sloane Coffin, and Dwight Macdonald. The activism landed him on President Nixon's master list of political opponents. His wife, Carol, began pursuing her own doctorate in linguistics so the family could survive if Chomsky were imprisoned or lost his position at MIT.

  In 1970, he traveled to southeast Asia, lecturing at Vietnam's Hanoi University of Science and Technology and touring war refugee camps in Laos. The London Times named him one of the makers of the twentieth century that same year. He continued publishing on linguistics during this period while also producing a succession of political books, among them At War with Asia in 1970 and Peace in the Middle East? in 1974. The mainstream press largely ignored him throughout, a fact he later used as evidence for his broader argument about how corporate media manages the range of permissible political opinion.

• 6. Manufacturing Consent

  ›

  Chomsky began collaborating with economist Edward S. Herman in the early 1970s, initially on a book that criticized U.S. military involvement in Southeast Asia and the failure of mainstream media to cover it adequately. Their publisher, Warner Modular, issued that first volume in 1973, but the parent company ordered all copies destroyed after objecting to the contents. They found a sympathetic home at Michael Albert's South End Press, an activist-oriented operation, which in 1979 published an expanded version as the two-volume Political Economy of Human Rights. It compared U.S. media coverage of the Cambodian genocide with coverage of Indonesia's occupation of East Timor, arguing that because Indonesia was a U.S. ally, American media ignored the occupation while focusing on Cambodia, a U.S. enemy.

  Chomsky and Herman's most influential collaboration, Manufacturing Consent: The Political Economy of the Mass Media, appeared in 1988 and laid out their propaganda model of media criticism in full. They argued that even in societies without official censorship, news is filtered through five mechanisms that constrain what gets covered and how. The book received a film adaptation in 1992.

  The central claim was not a conspiracy theory, Chomsky insisted, but a description of institutions following their natural imperatives. Corporate-owned media reflects corporate priorities. Journalists may be dedicated, but the range of opinion and the unquestioned premises of coverage are structured to avoid undermining the wider state-corporate arrangement. As evidence, he cited the absence of socialist journalists in U.S. mass media and specific stories that went unreported, including what he characterized as insufficient coverage of the far larger number of Palestinian deaths relative to Israeli deaths in coverage of that conflict.

• 7. The Faurisson Affair

  ›

  Chomsky had long and publicly criticized Nazism, but his commitment to unconditional freedom of speech led him in the late 1970s to defend the right of French historian Robert Faurisson to express positions widely characterized as Holocaust denial. Without Chomsky's knowledge, his statement in defense of Faurisson's right to speak was published as the preface to Faurisson's 1980 book Mémoire en défense contre ceux qui m'accusent de falsifier l'histoire. France's mainstream press accused Chomsky of being a Holocaust denier and refused to publish his rebuttals.

  Sociologist Werner Cohn later published an analysis of the episode titled Partners in Hate: Noam Chomsky and the Holocaust Deniers. The Anti-Defamation League called Chomsky a Holocaust denier outright. Chomsky responded that defending the right to speak is not the same as endorsing what is said, but the distinction persuaded few of his critics in France, and the affair had a lasting, damaging effect on his reputation there.

  His commentary on the Cambodian genocide and the Bosnian genocide generated additional controversy. Marxist academic Steven Lukes publicly accused Chomsky of acting as an apologist for Pol Pot. Chomsky declined to call the Srebrenica massacre a genocide, though he described it as a horror story and major crime, arguing it did not meet his definition of the term. Critics characterized this as denial. Chomsky's collaborator Edward Herman said the controversies over the political work imposed a serious personal cost on Chomsky, who believed that the suppression and justification of state crimes by mainstream intellectuals mattered more than the personal criticism he received.

• 8. Legacy and Late Life

  ›

  Chomsky retired from MIT in 2002, but continued research and seminars on campus. That same year he traveled to Turkey to attend the trial of a publisher accused of treason for printing one of his books. Chomsky insisted on being named a co-defendant, and amid international media attention the Security Courts dropped the charge on the first day of trial. He was voted the world's leading public intellectual in the 2005 Global Intellectuals Poll, conducted jointly by the magazines Foreign Policy and Prospect. In 2011, the US Peace Memorial Foundation awarded him the US Peace Prize for antiwar activities over five decades.

  He married his second wife, Valeria Wasserman, a translator at the University of Sao Paulo, in 2014, the year after his first wife Carol died. The couple purchased a home in Brazil in 2015 and began splitting their time between the two countries. In June 2023, Chomsky suffered a massive stroke and was flown to a hospital in Sao Paulo. He can no longer walk or communicate, and his return to public life has been described as improbable. He was discharged in June 2024 to continue recovery at home, and as of late 2025 he remained in Brazil.

  In November 2025, emails released by the House Oversight Committee revealed that Chomsky had befriended Jeffrey Epstein after Epstein's 2008 conviction and remained in contact through at least 2019, describing Epstein in a letter as a highly valued friend and regular source of intellectual exchange and stimulation. Congress subsequently released a photograph of Chomsky with Steve Bannon from Epstein's estate and another showing him on Epstein's private plane. In 2026, Chomsky's wife Valeria wrote that the relationship had been a grave mistake and apologized on his behalf, describing their realization that they had engaged with someone who led a hidden life of criminal, inhumane, and perverted acts.
