Michel Foucault is considered one of the most important philosophers of the 20th century. Marita Rainsborough examines the current relevance of his work with reference to the post- and decolonial theories of Achille Mbembe, Homi Bhabha and Walter D. Mignolo in a global context. She incorporates the philosophy of Judith Butler and Byung-Chul Han as well as New Realism into the critical reading of Foucault, and emphasises the philosophical references to Bloch and Kant that have so far been neglected in his reception. Considering the subject between knowledge, power, ethics and aesthetics, an overall review as well as new aspects for the philosophical discussion of this French classic are offered.
