In the 1950s and 1960s, Hans Blumenberg envisioned a connection between the philosophy of technology and the philosophy of time, a topic that is rarely referenced even today. This may be because he never wrote a "philosophy of technology." However, his estate contains a number of shorter writings in which he articulates his thoughts on this subject in a pointed manner. Initially, these works were influenced by a clear distinction between nature and technology, but he increasingly distances himself from this perspective in the context of the legitimacy of modernity, bringing the concepts of self-preservation and self-assertion to the forefront. This volume brings together all of Blumenberg's contributions from this context for the first time, making his philosophy of technology tangible.
