As a domain of enquiry within the study of material culture, “technology” occupies a very paradoxical place. It is at the same time pervasive, infusing subfields such as design, art, infrastructure, or the digital, and yet it is conspicuously absent as a distinct topic compared to, for instance, religion, art, or consumption. This chapter explores the history of thinking surrounding the concept of “technology” and its components of technical activities, objects, and systems.
