Genealogy of Knowledge: History and the Construction of Truth is a work that challenges the reader to delve into the origins of the truths we take for granted, revealing how these are, in essence, social constructions shaped by power dynamics, historical context and cultural forces. This book, inspired by thinkers such as Nietzsche and Foucault, leads us to explore the foundations of knowledge from a critical and genealogical approach.Through historical and scientific examples, it analyzes how dominant narratives have been used to justify inequalities, consolidate ideologies, and exclude alternative voices. From the concept of race in 19th century anthropology to the biases present in current technologies, the author reveals how these "truths" have influenced our social and political structures.This work is more than an academic analysis; it is a call to rethink our understanding of the past and to critically examine the present. It invites us to question what we accept as true, to uncover hidden narratives, and to imagine new forms of knowledge that are inclusive and ethically responsible.
