The 23 essays that form The truth about the technical world -written between 1978 and 2010- are meant to represent the development of Friedrich Kittler's thinking and show the strong ties between the communications technology and sociability. His innovative and eclectic investigation about the media as object of philosophical reflections helped him analyze the nodal and controversial aspects of the modern world. The importance of war for the consolidation of the modern media, musical essays about Pink Floyd, and the risky interpretations of the ancient Greece are just an example of the investigation included in this work.
