This book examines the work of Jünger and its effect on the development of Heideggers philosophy of technology. It offers a unique treatment of Jüngers philosophy and his conception of the age of technology, in which both world and man appear in terms of their functionality and efficiency. It demonstrates Jüngers influence on Heideggers conceptions of will, work and gestalt at the beginning of the 1930s. At the same time, Blok evaluates Heideggers criticism of Jünger and provides a novel interpretation of the Jünger-Heidegger connection: that Jüngers work in fact testifies to a transformation of our relationship to language and conceptualizes the future in terms of the Anthropocene.
