'What does it mean to be human?' This age-old question has gained new urgency in the light of current technological developments. This volume addresses these developments, as well as the impact they have on human self-understanding, particularly from the perspective of Christian theological anthropology. This volume consists of fourteen chapters, divided into four different parts. The first part explores the challenges that contemporary technology poses with regard to human self-understanding. In the second part, the conceptual assumptions of technological developments themselves are critically questioned. The third part offers theological perspectives on technological developments and assumptions. The fourth and last part of the book returns to the empirical realm, describing the ethical challenges that can be experienced living with complex technology.
