Book excerpt: Twenty-three essays that document the intellectual itinerary of the philosopher and cultural historian, one of the most original thinkers in recent times. Friedrich Kittler (1943–2011) combined the study of literature, cinema, technology, and philosophy in a manner sufficiently novel to be recognized as a new field of academic endeavor in his native Germany. “Media studies,” as Kittler conceived it, meant reflecting on how books operate as films, poetry as computer science, and music as military equipment. This volume collects writings from all stages of the author’s prolific career. Exemplary essays illustrate how matters of form and inscription make heterogeneous source material (e.g., literary classics and computer design) interchangeable on the level of function—with far-reaching consequences for our understanding of the humanities and the “hard sciences.” Rich in counterintuitive propositions, sly humor, and vast erudition, Kittler’s work both challenges the assumptions of positivistic cultural history and exposes the over-abstraction and language games of philosophers such as Heidegger and Derrida.
