This book highlights and develops a hitherto neglected area of Hans Blumenberg's contributions, i.e., history and philosophy of science. It covers both Blumenberg's works on the history of ideas and conceptual change, as well as his studies on transformative periods and his intellectual history of technology. Hans Blumenberg (1920-1996) was one of the leading German philosophers after the Second World War, bridging from the continental tradition of philosophy, conceptual history and metaphorology. This volume, though, explores the methodological instruments that he developed and how we may use them to do history and philosophy of science. In doing so it opens up a new field of research and provides insight into further developing a continental history and philosophy of science, making this book of great interest to both historians and philosophers alike.
