The article discusses the technical image, a central concept in Vilém Flusser’s later main work Into the Universe of Technical Images (1985a). After identifying its various dimensions, the analysis frames the concept as an amalgamation of disciplines, theories, and artistic practices the cultural philosopher Flusser explored during the 1960s and especially the 1970s. In particular, the field of information aesthetics developed by Max Bense and Abraham A. Moles, among others, as well as artistic video practices in France and the United States played an important role in both Flusser’s biography and the formation of his technical image concept. At the same time, in Flusser’s cultural philosophy the technical image is the condition and result of a new kind of human imagination, which in this paper is specified as ‘projective imagination’.
