People nowadays live in a human-made environment, or technotope. Their lives are entangled with technology. Because technology not only brings gifts but also costs and hazards, it is important to reflect on what good technology is and, indeed, whether a technology contributes to a good life. The ethicists and social scientists united in this volume contribute to a novel approach to ethics and technology that initiates or enhances timely ethical reflection with scientists and engineers. Ethical reflection during research and development can help to anticipate how it can change human (social) like, and evaluate those changes. Ethics on the Laboratory Floor contributes to research decisions, for example with regard to what research goals to pursue, what research lines to prioritise, or how best to design user tests. By joining these deliberations Ethics on the Laboratory Floor helps to realise the best technological alternatives.
