Racial prejudice in the context of "Anti-racism"

Essentialism is the view that objects have a set of attributes that are necessary to their identity. In early Western thought, Platonic idealism held that all things have such an "essence"—an "idea" or "form". In Categories, Aristotle similarly proposed that all objects have a substance that, as George Lakoff put it, "make the thing what it is, and without which it would be not that kind of thing". The contrary view—non-essentialism—denies the need to posit such an "essence". Essentialism has been controversial from its beginning. In the Parmenides dialogue, Plato depicts Socrates questioning the notion, suggesting that if we accept the idea that every beautiful thing or just action partakes of an essence to be beautiful or just, we must also accept the "existence of separate essences for hair, mud, and dirt".

Older social theories were often conceptually essentialist. In biology and other natural sciences, essentialism provided the rationale for taxonomy at least until the time of Charles Darwin. The role and importance of essentialism in modern biology is still a matter of debate. Beliefs which posit that social identities such as race, ethnicity, nationality, or gender are essential characteristics have been central to many discriminatory or extremist ideologies. For instance, psychological essentialism is correlated with racial prejudice. Essentialist views about race have also been shown to diminish empathy when dealing with members of another racial group. In medical sciences, essentialism can lead to a reified view of identities, leading to fallacious conclusions and potentially unequal treatment.

Paul-Michel Foucault (UK: /ˈfuːkoʊ/ FOO-koh, US: /fuːˈkoʊ/ foo-KOH; French: [pɔl miʃɛl fuko]; 15 October 1926 – 25 June 1984) was a French historian of ideas and philosopher, who was also an author, literary critic, political activist, and teacher. Foucault's theories primarily addressed the relationships between power versus knowledge and liberty, and he analyzed how they are used as a form of social control through multiple institutions. Though often cited as a structuralist and postmodernist, Foucault rejected these labels and sought to critique authority without limits on himself. His thought has influenced academics within a large number of contrasting areas of study, with this especially including those working in anthropology, communication studies, criminology, cultural studies, feminism, literary theory, psychology, and sociology. His efforts against homophobia and racial prejudice as well as against other ideological doctrines have also shaped research into critical theory and Marxism–Leninism alongside other topics.

Born in Poitiers, France, into an upper-middle-class family, Foucault was educated at the Lycée Henri-IV, at the École Normale Supérieure, where he developed an interest in philosophy and came under the influence of his tutors Jean Hyppolite and Louis Althusser, and at the University of Paris (Sorbonne), where he earned degrees in philosophy and psychology. After several years as a cultural diplomat abroad, he returned to France and published his first major book, The History of Madness (1961). After obtaining work between 1960 and 1966 at the University of Clermont-Ferrand, he produced The Birth of the Clinic (1963) and The Order of Things (1966), publications that displayed his increasing involvement with structuralism, from which he later distanced himself. These first three histories exemplified a historiographical technique Foucault was developing, which he called "archaeology".
