It has become a truism that we all think in the narrative mode, both in everyday life and in science. But what does this mean precisely? Scholars tend to use the term ‘narrative’ in a broad sense, implying not only event-sequencing but also the representation of emotions, basic perceptual processes or complex analyses of data sets. The volume addresses this blind spot by using clear selection criteria: only non-fictional texts by experts are analysed through the lens of both classical and postclassical narratology – from Aristotle to quantum physics and from nineteenth-century psychiatry to early childhood psychology; they fall under various genres such as philosophical treatises, case histories, textbooks, medical reports, video clips, and public lectures. The articles of this volume examine the central but continuously shifting role that event-sequencing plays within scholarly and scientific communication at various points in history – and the diverse functions it serves such as eye witnessing, making an argument, inferencing or reasoning. Thus, they provide a new methodological framework for both literary scholars and historians of science and medicine.

The idea of contagious transmission, either by material particles or by infectious ideas, has played a powerful role in the development of the Western World since antiquity. Yet it acquired quite a precise signature during the process of scientific and cultural differentiation in the 19th and early 20th centuries. This volume explores the significance and cultural functions of contagionism in this period, from notions of infectious homosexuality and the concept of social contagion to the political implications of bacteriological fieldwork. The history of the concept 'microbe' in aesthetic modernism is adressed as well as bacteriological metaphors in American literary historiography. Within this broad framework, contagionism as a literary narrative is approached in more focussed contributions: from its emotional impact in literary modernism to the idea of physical or psychic contagion in authors such as H.G. Wells, Kurt Lasswitz, Gustav Meyrinck, Ernst Weiss, Thomas Mann and Max Frisch. This twofold approach of general topics and individual literary case studies produces a deeper understanding of the symbolic implications of contagionism marking the boundaries between sick and healthy, familiar and alien, morally pure and impure.
