Estas cinco conferencias, dictadas por Michel Foucault en la Universidad Católica de Río de Janeiro en 1973, desarrollan las tesis básicas a partir de las cuales construiría más adelante una de sus obras Vigilar y castigar, en la que examina el nacimiento de la prisión moderna como reflejo de las estrategias de vigilancia y control del poder a partir del siglo XIX. Partiendo de una idea originaria de Nietzsche, Foucault investiga en la presente obra las formas de establecer la verdad en la Grecia antigua, en la Edad Media y en el Estado moderno. Así construye una genealogía del poder y de su paulatino entrelazamiento íntimo, oscuro y eficaz que configura la totalidad de las relaciones sociales de nuestra época. Estos estudios guardan todo el frescor de una teoría en pleno desarrollo, que encontró su forma definitiva en las obras posteriores con los que Michel Foucault se convirtió en uno de los pensadores más originales e influyentes del presente.
Paul-Michel Foucault was a French philosopher, historian of ideas, writer, political activist, and literary critic. Foucault's theories primarily address the relationships between power and knowledge, and how they are used as a form of social control through societal institutions. Though often cited as a structuralist and postmodernist, Foucault rejected these labels. His thought has influenced academics, especially those working in communication studies, anthropology, psychology, sociology, criminology, cultural studies, literary theory, feminism, Marxism and critical theory. 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 called "archaeology". From 1966 to 1968, Foucault lectured at the University of Tunis before returning to France, where he became head of the philosophy department at the new experimental university of Paris VIII. Foucault subsequently published The Archaeology of Knowledge (1969). In 1970, Foucault was admitted to the Collège de France, a membership he retained until his death. He also became active in several left-wing groups involved in campaigns against racism and human rights abuses and for penal reform. Foucault later published Discipline and Punish (1975) and The History of Sexuality (1976), in which he developed archaeological and genealogical methods that emphasized the role that power plays in society. Foucault died in Paris from complications of HIV/AIDS; he became the first public figure in France to die from complications of the disease. His partner Daniel Defert founded the AIDES charity in his memory.
No era, hasta el momento, excesivamente fanático de Foucault, pero tengo que admitir que he cambiado de opinión. La originalidad de las reflexiones de este ensayo y el profundo conocimiento de la historia de las instituciones jurídicas —sorprendente, teniendo en cuenta que Foucault no era jurista— hace que, en adelante, no pueda pensar en el Derecho de la misma manera. Debería ser de lectura obligada en las facultades de Derecho.
