The philosophy of technology has been dominated by metaphysical analyses of the "essence" of technology and by moral/critical reflections on the consequences of technology for individual and social forms of life. To develop a more internally oriented philosophy of technology, the authors in this volume believe that an empirical turn is necessary, similar to the turn witnessed in the philosophy of science. In this volume, authors explore the various ways in which empirical data can be used in ontological, epistemological, ethical or more general discussions in the philosophy of technology. All the chapters in the volume therefore contribute to an empirical turn in the philosophy of technology.
