About Avram Noam Chomsky
Avram Noam Chomsky (pronounced /ˌnoʊm ˈtʃɒmski/, Hebrew: חומסקי נועם אַבְרָהָם; born December 7, 1928) is an American linguist, philosopher, cognitive scientist, and political activist. He is an Institute Professor and professor emeritus of linguistics at the Massachusetts Institute of Technology Chomsky is well known in the academic and scientific community as one of the fathers of modern linguistics. Since the 1960s, he has become known more widely as a political dissident and an anarchist.
According to the Arts and Humanities Citation Index in 1992, Chomsky was cited as a source more often than any other living scholar during the 1980–92 period, and was the eighth most-cited source. He is also considered a prominent cultural figure. At the same time, his status as a leading critic of U.S. foreign policy has made him controversial.
In the 1950s, Chomsky began developing his theory of generative grammar, which has undergone numerous revisions and has had a profound influence on linguistics. His approach to the study of language emphasizes "an innate set of linguistic principles shared by all humans" known as universal grammar, "the initial state of the language learner," and discovering an "account for linguistic variation via the most general possible mechanisms."
He elaborated on these ideas in 1957's Syntactic Structures, which then laid the groundwork for the concept of transformational grammar. He also established the Chomsky hierarchy, a classification of formal languages in terms of their generative power.
In 1959, Chomsky published a widely influential review of B. F. Skinner's theoretical book Verbal Behavior. In this review and other writings, Chomsky broadly and aggressively challenged the behaviorist approaches to studies of behavior and language dominant at the time, and contributed to the cognitive revolution in psychology. His naturalistic approach to the study of language has influenced the philosophy of language and mind.
Beginning with his opposition to the Vietnam War, first articulated in his 1967 essay "The Responsibility of Intellectuals" and later extended in his American Power and the New Mandarins (1969), Chomsky established himself as a prominent critic of U.S. foreign and domestic policy. He has since become an outspoken political commentator and a dedicated activist; he is a self-declared anarcho-syndicalist and a libertarian socialist, principles he believes are grounded in the philosophy of classical liberalism and the Age of Enlightenment. His social criticism has also included an analysis of the mass media; his Manufacturing Consent: The Political Economy of the Mass Media (1988), co-written with Edward S. Herman, articulated the propaganda model theory for examining the media.
Chomsky was born on the morning of December 7, 1928 to Jewish parents in the affluent East Oak Lane neighborhood of Philadelphia, Pennsylvania, the son of noted professor of Hebrew at Gratz College and IWW (Industrial Workers of the World) member William Chomsky (1896–1977), a native of Ukraine. His mother, Elsie Chomsky (née Simonofsky), a native of what is present-day Belarus, grew up in the United States and, unlike her husband, spoke "ordinary New York English." Their first language was Yiddish, but Chomsky said it was "taboo" in his family to speak it.
Although his mother was part of the the radical activism in the 30s, Chomsky was largely influenced by his uncle. Having never passed 4th grade, he owned a newsstand that acted as an "intellectual center [where] professors of this and that arguing all night" Chomsky was also influenced by being a part of a Hebrew-based, Zionist organization as well as hanging around anarchist bookstores.
He describes his family as living in a sort of "Jewish ghetto," split into a "Yiddish side" and "Hebrew side," with his family aligning with the latter and bringing him up "immersed in Hebrew culture and literature."
Chomsky also describes tensions he personally experienced with Irish Catholics and German Catholics and anti-semitism in the mid-1930s. He recalls German-American "Beer parties" celebrating the fall of Paris to the Nazis.
In a discussion of the irony of his staying in the 1980s in a Jesuit House in Central America, Chomsky explained that during his childhood, "We were the only Jewish family around. I grew up with a visceral fear of Catholics. They're the people who beat you up on your way to school. So I knew when they came out of that building down the street, which was the Jesuit school, they were raving anti-Semites. So childhood memories took a long time to overcome."
Chomsky remembers the first article he wrote was at age 10 while a student at Oak Lane Country Day School about the threat of the spread of fascism, following the fall of Barcelona in the Spanish Civil War. From the age of 12 or 13, he identified more fully with anarchist politics.
A graduate of Central High School of Philadelphia, Chomsky began studying philosophy and linguistics at the University of Pennsylvania in 1945, taking classes with philosophers such as C. West Churchman and Nelson Goodman and linguist Zellig Harris.
Harris's teaching included his discovery of transformations as a mathematical analysis of language structure (mappings from one subset to another in the set of sentences). Chomsky referred to the morphophonemic rules in his 1951 Master's Thesis, The Morphophonemics of Modern Hebrew, as transformations in the sense of Carnap's 1938 notion of rules of transformation (vs. rules of formation), and subsequently reinterpreted the notion of grammatical transformations in a very different way from Harris, as operations on the productions of a context-free grammar (derived from Post production systems). Harris's political views were instrumental in shaping those of Chomsky. Chomsky earned a BA in 1949 and an MA in 1951.
In 1949, he married linguist Carol Schatz. They remained married for 59 years until her death from cancer in December 2008. The couple had two daughters, Aviva (b. 1957) and Diane (b. 1960), and a son, Harry (b. 1967). With his wife Carol, Chomsky spent time in 1953 living in HaZore'a, a kibbutz in Israel.
Asked in an interview whether the stay was "a disappointment" Chomsky replied, "No, I loved it," however he "couldn't stand the ideological atmosphere" and "fervent nationalism" in the early 1950s at the kibbutz, with Stalin being defended by many of the left-leaning kibbutz members who chose to paint a rosy image of future possibilities and contemporary realities in the USSR.
Chomsky notes seeing many positive elements in the commune-like living of the kibbutz, in which parents and children lived in rooms of separate houses together, and when asked whether there were "lessons that we have learned from the history of the kibbutz," responded, that in "some respects, the Kibbutzim came closer to the anarchist ideal than any other attempt that lasted for more than a very brief moment before destruction, or that was on anything like a similar scale. In these respects, I think they were extremely attractive and successful; apart from personal accident, I probably would have lived there myself – for how long, it's hard to guess".
Chomsky received his PhD in linguistics from the University of Pennsylvania in 1955. He conducted part of his doctoral research during four years at Harvard University as a Harvard Junior Fellow. In his doctoral thesis, he began to develop some of his linguistic ideas, elaborating on them in his 1957 book Syntactic Structures, his best-known work in linguistics.
Chomsky joined the staff of the Massachusetts Institute of Technology (MIT) in 1955 and in 1961 was appointed full professor in the Department of Modern Languages and Linguistics (now the Department of Linguistics and Philosophy). From 1966 to 1976 he held the Ferrari P. Ward Professorship of Modern Languages and Linguistics, and in 1976 he was appointed Institute Professor. As of 2010, Chomsky has taught at MIT continuously for 55 years.
In February 1967, Chomsky became one of the leading opponents of the Vietnam War with the publication of his essay, "The Responsibility of Intellectuals", in The New York Review of Books. This was followed by his 1969 book, American Power and the New Mandarins, a collection of essays that established him at the forefront of American dissent. His far-reaching criticisms of U.S. foreign policy and the legitimacy of U.S. power have made him a controversial figure: largely shunned by the mainstream media in the United States, he is frequently sought out for his views by publications and news outlets internationally. In 1977 he delivered the Huizinga Lecture in Leiden, The Netherlands, under the title: Intellectuals and the State.
Chomsky has received death threats because of his criticisms of U.S. foreign policy. He was also on a list of planned targets created by Theodore Kaczynski, better known as the Unabomber; during the period that Kaczynski was at large, Chomsky had all of his mail checked for explosives. He states that he often receives undercover police protection, in particular while on the MIT campus, although he does not agree with the police protection
Chomsky resides in Lexington, Massachusetts and travels often, giving lectures on politics.
Contributions to linguistics
Chomskyan linguistics, beginning with his Syntactic Structures, a distillation of his Logical Structure of Linguistic Theory (1955, 75), challenges structural linguistics and introduces transformational grammar. This approach takes utterances (sequences of words) to have a syntax characterized by a formal grammar; in particular, a context-free grammar extended with transformational rules.
Perhaps his most influential and time-tested contribution to the field, is the claim that modeling knowledge of language using a formal grammar accounts for the "productivity" of language. In other words, a formal grammar of a language can explain the ability of a hearer-speaker to produce and interpret an infinite number of utterances, including novel ones, with a limited set of grammatical rules and a finite set of terms. He has always acknowledged his debt to Pāṇini for his modern notion of an explicit generative grammar although it is also related to Rationalist ideas of a priori knowledge.
It is a popular misconception that Chomsky proved that language is entirely innate and discovered a "universal grammar" (UG). In fact, Chomsky simply observed that while a human baby and a kitten are both capable of inductive reasoning, if they are exposed to the exact same linguistic data, the human child will always acquire the ability to understand and produce language, while the kitten will never acquire either ability. Chomsky labeled whatever the relevant capacity the human has which the cat lacks the "language acquisition device" (LAD) and suggested that one of the tasks for linguistics should be to figure out what the LAD is and what constraints it puts on the range of possible human languages. The universal features that would result from these constraints are often termed "universal grammar" or UG.
The Principles and Parameters approach (P&P)—developed in his Pisa 1979 Lectures, later published as Lectures on Government and Binding (LGB)—make strong claims regarding universal grammar: that the grammatical principles underlying languages are innate and fixed, and the differences among the world's languages can be characterized in terms of parameter settings in the brain (such as the pro-drop parameter, which indicates whether an explicit subject is always required, as in English, or can be optionally dropped, as in Spanish), which are often likened to switches. (Hence the term principles and parameters, often given to this approach.) In this view, a child learning a language need only acquire the necessary lexical items (words, grammatical morphemes, and idioms), and determine the appropriate parameter settings, which can be done based on a few key examples.
Proponents of this view argue that the pace at which children learn languages is inexplicably rapid, unless children have an innate ability to learn languages. The similar steps followed by children all across the world when learning languages, and the fact that children make certain characteristic errors as they learn their first language, whereas other seemingly logical kinds of errors never occur (and, according to Chomsky, should be attested if a purely general, rather than language-specific, learning mechanism were being employed), are also pointed to as motivation for innateness.
More recently, in his Minimalist Program (1995), while retaining the core concept of "principles and parameters," Chomsky attempts a major overhaul of the linguistic machinery involved in the LGB model, stripping from it all but the barest necessary elements, while advocating a general approach to the architecture of the human language faculty that emphasizes principles of economy and optimal design, reverting to a derivational approach to generation, in contrast with the largely representational approach of classic P&P.
Chomsky's ideas have had a strong influence on researchers investigating the acquisition of language in children, though researchers who work in this area such as Elizabeth Bates and Michael Tomasello today do not support Chomsky's theories, instead advocating emergentist or connectionist theories reducing language to an instance of general processing mechanisms in the brain.
His best-known work in phonology is The Sound Pattern of English (1968), written with Morris Halle (and often known as simply SPE). This work has had a great significance for the development in the field. While phonological theory has since moved beyond "SPE phonology" in many important respects, the SPE system is considered the precursor of some of the most influential phonological theories today, including autosegmental phonology, lexical phonology and optimality theory. Chomsky no longer publishes on phonology.
The Chomskyan approach towards syntax, often termed generative grammar, studies grammar as a body of knowledge possessed by language users. Since the 1960s, Chomsky has maintained that much of this knowledge is innate, implying that children need only learn certain parochial features of their native languages. The innate body of linguistic knowledge is often termed Universal Grammar. From Chomsky's perspective, the strongest evidence for the existence of Universal Grammar is simply the fact that children successfully acquire their native languages in so little time. Furthermore, he argues that there is an enormous gap between the linguistic stimuli to which children are exposed and the rich linguistic knowledge they attain (the "poverty of the stimulus" argument). The knowledge of Universal Grammar would serve to bridge that gap.
Chomsky's theories are popular, particularly in the United States, but they have never been free from controversy. Criticism has come from a number of different directions. Chomskyan linguists rely heavily on the intuitions of native speakers regarding which sentences of their languages are well-formed. This practice has been criticized both on general methodological grounds, and because it has (some argue) led to an overemphasis on the study of English. As of now, hundreds of different languages have received at least some attention in the generative grammar literature, but some critics nonetheless perceive this overemphasis, and a tendency to base claims about Universal Grammar on an overly small sample of languages. Some psychologists and psycholinguists,[who?] though sympathetic to Chomsky's overall program, have argued that Chomskyan linguists pay insufficient attention to experimental data from language processing, with the consequence that their theories are not psychologically plausible. Other critics (see language learning) have questioned whether it is necessary to posit Universal Grammar to explain child language acquisition, arguing that domain-general learning mechanisms are sufficient.
Today there are many different branches of generative grammar; one can view grammatical frameworks such as head-driven phrase structure grammar, lexical functional grammar and combinatory categorial grammar as broadly Chomskyan and generative in orientation, but with significant differences in execution.
Cultural anthropologist and linguist Daniel Everett of Illinois State University has proposed that the language of the Pirahã people of the northwestern rainforest of Brazil resists Chomsky's theories of generative grammar. Everett asserts that the Pirahã language does not have any evidence of recursion, one of the properties that makes generative grammar possible. If true, this would also seem to contradict Chomsky's hypothesis that recursion is the defining feature of the human mind. However, Everett's claims have themselves been criticized. David Pesetsky of MIT, Andrew Nevins of Harvard, and Cilene Rodrigues of the Universidade Estadual de Campinas in Brazil have argued in a joint paper that all of Everett's major claims contain serious deficiencies. Chomsky himself has commented that "The reports are interesting, but do not bear on the work of mine (along with many others). No one has proposed that languages must have subordinate clauses, number words, etc. Many structures of our language (and presumably that of the Piraha) are rarely if ever used in ordinary speech because of extrinsic constraints." The dispute continues.
Chomsky is famous for investigating various kinds of formal languages and whether or not they might be capable of capturing key properties of human language. His Chomsky hierarchy partitions formal grammars into classes, or groups, with increasing expressive power, i.e., each successive class can generate a broader set of formal languages than the one before. Interestingly, Chomsky argues that modeling some aspects of human language requires a more complex formal grammar (as measured by the Chomsky hierarchy) than modeling others. For example, while a regular language is powerful enough to model English morphology, it is not powerful enough to model English syntax. In addition to being relevant in linguistics, the Chomsky hierarchy has also become important in computer science (especially in compiler construction and automata theory).

 Contributions to psychology
Chomsky's work in linguistics has had profound implications for modern psychology. For Chomsky, linguistics is a branch of cognitive psychology; genuine insights in linguistics imply concomitant understandings of aspects of mental processing and human nature. His theory of a universal grammar was seen by many as a direct challenge to the established behaviorist theories of the time and had major consequences for understanding how children learn language and what, exactly, the ability to use language is.
In 1959, Chomsky published an influential critique of B.F. Skinner's Verbal Behavior, a book in which Skinner offered a theoretical account of language in functional, behavioral terms. "Verbal behavior" he defined as learned behavior that has characteristic consequences delivered through the learned behavior of others. This makes for a view of communicative behaviors much larger than that usually addressed by linguists. Skinner's approach focused on the circumstances in which language was used; for example, asking for water was functionally a different response than labeling something as water, responding to someone asking for water, etc. These functionally different kinds of responses, which required in turn separate explanations, sharply contrasted both with traditional notions of language and Chomsky's psycholinguistic approach. Chomsky thought that a functionalist explanation restricting itself to questions of communicative performance ignored important questions. (Chomsky—Language and Mind, 1968). He focused on questions concerning the operation and development of innate structures for syntax capable of creatively organizing, cohering, adapting and combining words and phrases into intelligible utterances.
In the review Chomsky emphasized that the scientific application of behavioral principles from animal research is severely lacking in explanatory adequacy and is furthermore particularly superficial as an account of human verbal behavior because a theory restricting itself to external conditions, to "what is learned", cannot adequately account for generative grammar. Chomsky raised the examples of rapid language acquisition of children, including their quickly developing ability to form grammatical sentences, and the universally creative language use of competent native speakers to highlight the ways in which Skinner's view exemplified under-determination of theory by evidence. He argued that to understand human verbal behavior such as the creative aspects of language use and language development, one must first postulate a genetic linguistic endowment. The assumption that important aspects of language are the product of universal innate ability runs counter to Skinner's radical behaviorism.
Chomsky's 1959 review has drawn fire from a number of critics, the most famous criticism being that of Kenneth MacCorquodale's 1970 paper On Chomsky’s Review of Skinner’s Verbal Behavior (Journal of the Experimental Analysis of Behavior, volume 13, pages 83–99). MacCorquodale's argument was updated and expanded in important respects by Nathan Stemmer in a 1990 paper, Skinner's Verbal Behavior, Chomsky's review, and mentalism (Journal of the Experimental Analysis of Behavior, volume 54, pages 307–319). These and similar critiques have raised certain points not generally acknowledged outside of behavioral psychology, such as the claim that Chomsky did not possess an adequate understanding of either behavioral psychology in general, or the differences between Skinner's behaviorism and other varieties; consequently, it is argued that he made several serious errors. On account of these perceived problems, the critics maintain that the review failed to demonstrate what it has often been cited as doing. As such, it is averred that those most influenced by Chomsky's paper probably either already substantially agreed with Chomsky or never actually read it. The review has been further critiqued for misrepresenting the work of Skinner and others, including by quoting out of context. Chomsky has maintained that the review was directed at the way Skinner's variant of behavioral psychology "was being used in Quinean empiricism and naturalization of philosophy".
It has been claimed that Chomsky's critique of Skinner's methodology and basic assumptions paved the way for the "cognitive revolution", the shift in American psychology between the 1950s through the 1970s from being primarily behavioral to being primarily cognitive. In his 1966 Cartesian Linguistics and subsequent works, Chomsky laid out an explanation of human language faculties that has become the model for investigation in some areas of psychology. Much of the present conception of how the mind works draws directly from ideas that found their first persuasive author of modern times in Chomsky.
There are three key ideas. First is that the mind is "cognitive", or that the mind actually contains mental states, beliefs, doubts, and so on. Second, he argued that most of the important properties of language and mind are innate. The acquisition and development of a language is a result of the unfolding of innate propensities triggered by the experiential input of the external environment. The link between human innate aptitude to language and heredity has been at the core of the debate opposing Noam Chomsky to Jean Piaget at the Abbaye de Royaumont in 1975 (Language and Learning. The Debate between Jean Piaget and Noam Chomsky, Harvard University Press, 1980). Although links between the genetic setup of humans and aptitude to language have been suggested at that time and in later discussions, we are still far from understanding the genetic bases of human language. Work derived from the model of selective stabilization of synapses set up by Jean-Pierre Changeux, Philippe Courrège and Antoine Danchin, and more recently developed experimentally and theoretically by Jacques Mehler and Stanislas Dehaene in particular in the domain of numerical cognition lend support to the Chomskyan "nativism".
It does not, however, provide clues about the type of rules that would organize neuronal connections to permit language competence. Subsequent psychologists have extended this general "nativist" thesis beyond language. Lastly, Chomsky made the concept of "modularity" a critical feature of the mind's cognitive architecture. The mind is composed of an array of interacting, specialized subsystems with limited flows of inter-communication. This model contrasts sharply with the old idea that any piece of information in the mind could be accessed by any other cognitive process (optical illusions, for example, cannot be "turned off" even when they are known to be illusions).
