From Deconstruction to Observation: On the Fundamental Structure and Dialectical Development of Foucault's Genealogical Method

Abstract

Foucault’s genealogical method developed into a coherent framework that reflects a dialectical progression. Rather than merely adopting Nietzsche’s morally critical genealogy aimed at value critique, Foucault transformed it into a “cartographic” approach for analyzing power structures. In his early seminal work Discipline and Punish, Foucault employed genealogy to reveal the core configuration of modernity-“power-knowledge-subject”-demonstrating the method’s potent deconstructive force as a tool for power analysis. Yet the success of this deconstruction also placed Foucault in a theoretical predicament: if the subject is entirely constituted by power-knowledge, where does its capacity for self-constitution lie? Consequently, Foucault’s later genealogical practice took a significant turn, especially in volumes two and three of The History of Sexuality. Here, his approach shifted from a “critical” genealogy aimed at exposing mechanisms of power to a constructive genealogy that adopts a stance of “detached observation” in presenting the history of self-techniques. This evolution marks the transformation of Foucault’s genealogy from a static methodology into a dialectical process that integrates “deconstruction” and “detached observation,” moving from “power analysis” toward “subject interpretation.” It not only enriches the substance of genealogy but also opens up new perspectives for understanding the formation of the modern subject and its ethical possibilities.
