Summary:
The aim of this entry is twofold: to describe a field of discourse that located around the protean status of the word and suffix graph in latter half of the nineteenth century, and to instantiate that discourse through a consideration of Etienne-Jules Marey’s méthode graphique [graphic method]. The discourse of graph may be considered to be a micro-discourse, a series of signifying practices that loosely—perhaps even unconsciously—organizes meaning not from the standpoint of a unifying discourse such as science or theology that organizes knowledge from the outside in but rather signifies a particular episteme from the inside out. The word and suffix graph appears in the names of many new technologies in the middle and late nineteenth century: photography, cinematography, cardiography, phonautograph, graphophone, heliography, telegraphy, ideograph, phonograph, seismograph, myography, etc. Beyond recognizing graph as a facile gesture of nomenclature, this entry argues that its prevalence signifies a culturally and historically specific micro-discourse with deep implications for the study of writing as such in the broader media ecology of the late nineteenth century. Marey’s graphic method represents a meta-example of this micro-discourse. Marey’s graphic method modernized the study of physiology by helping to displace quasi-mystical theories of vitalism with a positivistic understanding of the human body. As writing, the indexical traces produced by means of the graphic method evidence a radical cultural transformation of the status of writing from transcendent signifying practice to the machinic writing of life based not upon a higher power but rather the movements of the body as machine. The graphic method takes part in a larger cultural and epistemic project of the scientific secularization of writing and inscription. (more…)
