Social Darwinism is an ideology of society that seeks to apply biological concepts of Darwinism or of evolutionary theory to sociology and politics, often with the assumption that conflict between groups in society leads to social progress as superior groups outcompete inferior ones.

The name social Darwinism is a modern name given to the various theories of society that emerged in England and the United States in the 1870s, which, it is alleged, sought to apply biological concepts to sociology and politics. The term social Darwinism gained widespread currency when used in 1944 to oppose these earlier concepts. Today, because of the negative connotations of the theory of social Darwinism, especially after the atrocities of the Second World War (including the Holocaust) few people would describe themselves as Social Darwinists and the term is generally seen as pejorative.

Social Darwinism is generally understood to use the concepts of struggle for existence and survival of the fittest to justify social policies which make no distinction between those able to support themselves and those unable to support themselves. Many such views stress competition between individuals in laissez-faire capitalism; but the ideology has also motivated ideas of eugenics, scientific racism, imperialism,fascism, Nazism and struggle between national or racial groups.

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.

Charles Robert Darwin, FRS (12 February 1809 – 19 April 1882) was an English naturalist. He established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection.

Darwin published his theory with compelling evidence for evolution in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s the scientific community and much of the general public had accepted evolution as a fact. However, many favoured competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's uniformitarian ideas, and publication of his journal of the voyage made him famous as a popular author.
