The cultural and philosophical study of software is crucial, both within and outside of the university, at an international level and across disciplines. Software is increasingly considered the focus of digital media studies because of the perceived need to address the invisibility, ubiquity, and power of digital media. Yet software remains quite obscure to students and scholars in media studies, the social sciences, and the humanities. This unique book engages directly in close readings of technical texts and computer code in order to show how software works and in what sense it can be considered constitutive of culture and even of human thought. Federica Frabetti combines this with an engagement with thinkers such as Bernard Steigler and Jacques Derrida to problematize the very nature of the conceptual system on which software is based and which has shaped its historical evolution. The book argues for a radical demystification of software and digital technologies by addressing the mystery that surrounds its function and that affects our comprehension of its relationship between technology, philosophy, culture, and society.
