The authors take the reader on a journey: from a discussion of the philosophy of praxis, via a hermeneutic notion of technical practice that draws on MacIntyre, Heidegger and Ricoeur, through the virtue ethics of Vallor, and Ricoeur’s ethical aim, to the eventual construction of a practice method which can guide ethics in research and innovation. In its creation of a compelling hermeneutic ethics of technology, the book offers a concrete framework for practitioners to incorporate ethics in everyday technical practice.
