humanistic and social scientific disciplines as one of the most influential and controversial scholars of the post-World War II period. According to a London School of Economics' analysis in 2016, his works Discipline and Punish and The History of Sexuality were among the 25 most cited books in the social sciences of all time, at just over 100,000 citations. In 2007, Foucault was listed as the single most cited scholar in the humanities by the ISI Web of Science among a large quantity of French philosophers, the compilation's author commenting that "What this says of modern scholarship is for the reader to decide—and it is imagined that judgments will vary from admiration to despair, depending on one's view". According to Gary Gutting, Foucault's "detailed historical remarks on the emergence of disciplinary and regulatory biopower have been widely influential". Leo Bersani wrote that:"[Foucault] is our most brilliant philosopher of power. More originally than any other contemporary thinker, he has attempted to define the historical constraints under which we live, at the same time that he has been anxious to account for—if possible, even to locate—the points at which we might resist those constraints and counter some of the moves of power. In the present climate of cynical disgust with the exercise of political power, Foucault's importance can hardly be exaggerated." Foucault's work on "biopower" has been widely influential within the disciplines of philosophy and political theory, particularly for such authors as Giorgio Agamben, Roberto Esposito, Antonio Negri, and Michael Hardt. His discussions on power and discourse have inspired many critical theorists, who believe that Foucault's analysis of power structures could aid the struggle against inequality. They claim that through discourse analysis, hierarchies may be uncovered and questioned by way of analyzing the corresponding fields of knowledge through which they are legitimated. This is one of the ways that Foucault's work is linked to critical theory. His work Discipline and Punish influenced his friend and contemporary Gilles Deleuze, who published the paper "Postscript on the Societies of Control", praising Foucault's work but arguing that contemporary western society has in fact developed from a 'disciplinary society' into a 'society of control'. Deleuze went on to publish a book dedicated to Foucault's thought in 1988 under the title Foucault. Foucault's discussions of the relationship between power and knowledge has influenced postcolonial critiques in explaining the discursive formation of colonialism, particularly in Edward Said's work
