This essay for the inaugural issue of Technology and Language is based on an analysis of the “epistemological turn” in modern cosmology and modern science, more generally. In view of another epistemological turn towards technology and a combinatorial approach to the creation of artefacts, the question regarding the languages of science and technology suggests itself. – When human beings relate to the world, they effectively address the world or talk to it, and the world talks back. This communication proceeds in different registers. It may have started in the idiom of myth. With the emergence of philosophy, a first language with a rational or methodical way of addressing the world came into being. Philosophy was superseded by the emergence of the language of science, and as of today, the language of technology comes into being and claims predominance.
