RIPOL Classic Publishing (Moscow) is producing a Russian edition of the Expanded Edition of Explaining Postmodernism: Skepticism and Socialism from Rousseau to Foucault. The publisher kindly sent me a draft image of the cover. The publication date for this translation is spring 2021.
The book’s thesis: The failure of epistemology made postmodernism possible, and the failure of socialism made postmodernism necessary.
