Facts are created. This raises epistemological as well as aesthetic questions, as they are emblematic of the absolute reality of the world. While common approaches in science studies explore their construction, this volume for the first time takes up the vividly revealing concept of "established facts." The discussion of the completed completion of facts proves to be fruitful for a historically broad philosophy of science, for science and technology studies, for historians of philosophy and science, as well as for design theory.
