Relativism is the concept that points of view have no absolute truth or validity, having only relative, subjective value according to differences in perception and consideration. The term is often used to refer to the context of moral principle, where in a relativistic mode of thought, principles and ethics are regarded as applicable in only limited context. There are many forms of relativism which vary in their degree of controversy. The term often refers to truth relativism, which is the doctrine that there are no absolute truths, i.e., that truth is always relative to some particular frame of reference, such as a language or a culture (cf. cultural relativism). Another widespread and contentious form is moral relativism. (See also moral relativism, aesthetic relativism, social constructionism, and cognitive relativism.)

Relativism is sometimes interpreted as saying that differing points of view are equally valid, in contrast to an absolutism which argues there is but one true and correct view.^{[citation needed]}

Avram Noam Chomsky (/ˈnoʊm ˈtʃɒmski/; born December 7, 1928) is an American linguist, philosopher,cognitive scientist, historian, and activist. He is an Institute Professor and Professor (Emeritus) in the Department of Linguistics & Philosophy at MIT, where he has worked for over 50 years. Chomsky has been described as the "father of modern linguistics" and a major figure of analytic philosophy. His work has influenced fields such as computer science, mathematics, and psychology.

Ideologically identifying with anarcho-syndicalism and libertarian socialism, Chomsky is known for his critiques of U.S. foreign policy and contemporary capitalism, and he has been described as a prominent cultural figure. His media criticism has included Manufacturing Consent: The Political Economy of the Mass Media (1988), co-written with Edward S. Herman, an analysis articulating the propaganda model theory for examining the media.

According to the Arts and Humanities Citation Index in 1992, Chomsky was cited as a source more often than any other living scholar from 1980 to 1992, and was the eighth most cited source overall. Chomsky is the author of over 100 books. He is credited as the creator or co-creator of the Chomsky hierarchy, the universal grammar theory, and the Chomsky–Schützenberger theorem.

Michel Foucault (French pronunciation: [miʃɛl fuko]), born Paul-Michel Foucault (15 October 1926 – 25 June 1984) was a French philosopher, social theorist and historian of ideas. He held a chair at the Collège de France with the title "History of Systems of Thought," and lectured at the University at Buffalo and the University of California, Berkeley.

Foucault is best known for his critical studies of social institutions, most notably psychiatry, social anthropology of medicine, the human sciences and the prison system, as well as for his work on the history of human sexuality. His writings on power, knowledge, and discourse have been widely influential in academic circles.

In the 1960s, he was associated with structuralism, a theoretical movement in social anthropology from which he later distanced himself. He also rejected the poststructuralist and postmodernist labels later attributed to him, preferring to classify his thought as a critical history of modernity rooted in Immanuel Kant. His project was particularly influenced by Nietzsche, his "genealogy of knowledge" being a direct allusion to Nietzsche's "genealogy of morality". In a late interview he definitively stated: "I am a Nietzschean."
