The "Writings in Four Volumes. Dits et Ecrits" by Michel Foucault offer a comprehensive collection of his most important texts published during his lifetime. The third volume of this edition contains a variety of essays, interviews, and shorter contributions that engage with the central concepts of biopolitics and governmentality. Foucault's theory of power is examined in depth here, critiquing the prevailing models of his time. Notably, the development of his new concept of power, which is also addressed in the first volume of "The History of Sexuality," is highlighted. These writings are not only theoretical explorations but also political statements that have gained relevance in today's context. Foucault's commitment to social and political issues is evident in his texts, making him a significant thinker whose ideas are still discussed today.
