"Genealogy, From Nietzsche to Foucault" is an academic book that explores the historical analyses of Friedrich Nietzsche and Michel Foucault. It highlights how these thinkers use the past to understand the present and shape the future. Nietzsche called for a targeted historical analysis to address the challenges of 19th-century social change. In contrast, Foucault developed his own method in the 20th century to examine the genealogical structures of our social and political institutions. The focus of this study is on Foucault's influential analysis in "Discipline and Punish: The Birth of the Prison," where he questions the emergence and power structures of the legal system and prisons. The book offers deep insights into the interactions between past and present and encourages critical engagement with the institutions that shape our lives today.
