Twelve years after his famous Essay on Some Problems Concerning the Normal and the Pathological (1943), the philosopher Georges Canguilhem (1904–1995) published a book-length study on the history of a single biological concept. Within France, his Formation of the Reflex Concept in the Seventeenth and Eighteenth Centuries (1955) contributed significantly to defining the “French style” of writing on the history of science. Outside of France, the book passed largely unnoticed. This paper re-reads Canguilhem’s study of the reflex concept with respect (...) to its historiographical and epistemological implications. Canguilhem defines concepts as complex and dynamic entities combining terms, definitions, and phenomena. As a consequence, the historiography of science becomes a rather complex task. It has to take into account textual and contextual aspects that develop independently of individual authors. In addition, Canguilhem stresses the connection between conceptual activities and other functions of organic individuals in their respective environments. As a result, biological concepts become tied to a biology of conceptual thinking, analogical reasoning, and technological practice. The paper argues that this seemingly circular structure is a major feature in Canguilhem’s philosophical approach to the history of the biological sciences. (shrink)

This paper addresses the visual culture of late-19th-century experimental physiology. Taking the case of Johann Nepomuk Czermak as a key example, it argues that images played a crucial role in acquiring experimental physiological skills. Czermak, Emil Du Bois-Reymond and other late-19th-century physiologists sought to present the achievements and perspective of their discipline by way of "immediate visual perception." However, the images they produced and presented for this purpose were strongly mediated. By means of specifically designed instruments, such as the "cardioscope," (...) the "contraction telegraph," and the "frog pistol," and of specifically constructed rooms, so-called "spectatoriums," physiologists trained and controlled the perception of their students before allowing them to conduct experiments on their own. Studying the material culture of physiological image production reveals that technological resources such as telegraphy, photography, and even railways contributed to making physiological facts anschaulich. At the same time, it shows that the more traditional image techniques of anatomy played an important role in physiological lecture halls, especially when it came to displaying the details of vivisection experiments to the public. Thus, the images of late 19th century physiology stood half-way between machines and organisms, between books and instruments. (shrink)

This article sheds new light on Bruno Latour’s sociology of science and technology by looking at his early study of the French writer, philosopher and editor Charles Péguy (1873–1914). In the early 1970s, Latour engaged in a comparative study of Péguy’s Clio and the four gospels of the New Testament. His 1973 contribution to a Péguy colloquium (published in 1977) offers rich insights into his interest in questions of time, history, tradition and translation. Inspired by Gilles Deleuze’s philosophy of difference, (...) Latour reads Clio as spelling out and illustrating the following argument: ‘Repetition is a machine to produce differences with identity’. However, in contrast to Deleuze’s work (together with Félix Guattari) on the materiality of machines, or assemblages [agencements], Latour emphasizes the semiotic aspects of the repetition/difference process. As in Péguy, the main model for this process is the Roman Catholic tradition of religious events. The article argues that it is this reading of Péguy and Latour’s early interest in biblical exegesis that inspired much of Latour’s later work. In Laboratory Life (Latour and Woolgar, 1979) and The Pasteurization of France (1988) in particular, problems of exegesis and tradition provide important stimuli for the analysis of scientific texts. In this context, Latour gradually transforms the question of tradition into the problem of reference. In a first step, he shifts the event that is transmitted and translated from the temporal dimension (i.e. the past) to the spatial (i.e. from one part of the laboratory to another). It is only in a second step that Latour resituates scientific events in time. As facts they are ‘constructed’ but nevertheless ‘irreducible’. They result, according to Latour, from the tradition of the future. As a consequence, the Latourian approach to science distances itself from the materialism of Deleuze and other innovative theoreticians. (shrink)

The 'Reaction experiment with Hipp chronoscope' is one of the classical experiments of modern psychology. This paper investigates the technological contexts of this experiment. It argues that the development of time measurement and communication in other areas of science and technology (astronomy, the clock industry) were decisive for shaping the material culture of experimental in psychology. The chronoscope was constructed by Matthaus Hipp (1813-1893) in the late 1840s. In 1861, Adolphe Hirsch (1830-1901) introduced the chronoscope for measuring the 'physiological time' (...) of astronomical observers. Hirsch's observatory at Neuchatel (Switzerland) served to control the quality of clocks produced in the nearby Jura mountains. Hipp provided the observatory with a telegraphic system that sent time signals to the centers of clock production. Time telegraphy constituted the stable surroundings of the reaction time experiments carried out by both astronomers and psychologists. This technology permitted precise measurements of short time intervals and offered to Hirsch, as well as to Wilhelm Wundt (1832-1920), a useful metaphor for conceptualizing their respective 'epistemic objects'. But time telegraphy also limited the possibilities of the experimental work conducted within its framework. In particular, noise from outside and inside the research sites at Neuchatel, Leipzig and elsewhere disturbed the precise communication of time. (shrink)

In What Is Philosophy?, Gilles Deleuze and Félix Guattari distinguish the functions of philosophy, art and science. According to this distinction, the primary purpose of philosophy is to invent concepts, the purpose of art to bring forth percepts, or sensorial aggregates, and that of science to delineate functions. This article aims to show that these distinctions are not as clear-cut as they appear. Using Deleuze and Guattari’s proposition that ‘philosophy is the art of forming, inventing, and fabricating concepts’ as a (...) reference point, it suggests that the corresponding philosophical practice is intimately connected to art and science. Studying the conceptual drawings in Deleuze’s texts, the article situates his philosophy in the French tradition of epistemology. As a result, the conceptual work of this philosophy can be seen as intensively responding to the creative problems posed by the dynamics of science in contemporary societies. (shrink)

ArgumentIn the winter of 1849–1850 in Königsberg, German physiologist Hermann von Helmholtz (1821–1894) conducted pioneering measurements concerning the propagation speed of stimulations in the living nerve. While recent historians of science have paid considerable attention to Helmholtz's uses of the graphic method, in particular his construction of an instrument called “myographion,” this paper draws attention to theinscription surfacesthat he used in effective ways for capturing and transmitting his findings. Against the background of recent archival findings, I show that Helmholtz used (...) isinglass copies of his graphical recordings in order to communicate the basic principle of previous measurements to the academic public. As the correspondence with his Berlin-based friend and colleague Emil du Bois-Reymond (1818–1896) and the subsequent development of the myographion make clear, these curves were not meant as measurements but functioned as demonstrations. In other words, Helmholtz's curves did provide “images of precision” (Olesko and Holmes 1993) – but they were not precise images. (shrink)

"Empirische Ästhetik hat heute Konjunktur. Doch sie ist keineswegs eine Erfindung der Gegenwart. Schon im späten 19. Jahrhundert wurden zahlreiche Versuche unternommen, wissenschaftlich exakte Methoden in die Untersuchung des Schönen einzuführen. Unter Anschluss an Disziplinen wie Physiologie, Psychologie und Sprachwissenschaft wird Ästhetik um 1900 zu einer Wissensform, die in ihren materiellen Grundlagen, in ihrer diskursiven Organisation sowie in ihren theoretischen Konsequenzen neuartige Verbindungen zwischen Gefühl und Genauigkeit erzeugt. Die Beiträge des Bandes diskutieren diese Entwicklung anhand verschiedener Facetten und Spielformen empirischer (...) Ästhetik, die von den frühen Einfühlungstheorien über experimentelle Laborforschungen bis hin zu Poetik und Kunstwissenschaft reichen."--Front inside flap of dust jacket. (shrink)

This paper presents and discusses the website. Under the title “The Virtual Laboratory: Essays and Resources on the Experimentalization of Life” it gives access to a massive collection of texts and images concerning the experimental life sciences of the 19th and early 20th century. The main focus is on physiology and psychology. Plant breeding is an additional theme. As of now, the Virtual Laboratory gives access to some 12,000 digital items, i.e. historical text books, journal articles, manuscripts, trade catalogs, photos, (...) films, audio files, etc. At the same time, the Virtual Laboratory is a platform for historians of science to publish and discuss their research on the experimentalization of life. Topics range from the history of precision time measurements in the physiological lab to the historical epistemology of hearing and the role of the Axolotl as an experimental animal in zoology. By way of a guided tour through the Virtual Laboratory, the paper describes the kind of epistemic space that was created. It argues that open access to historical sources as well as tight connections between historical research papers and their raw data, e.g. manuscript sources, profoundly change what used to be called the Archive. Today’s historians of science have started to work within a space that is widely distributed and extremely flexible with respect to its internal connections. It is a space that turns the Archive into an authentic laboratory for the science historian. (shrink)

In 1955, Norbert Wiener suggested a sociological model according to which all forms of culture ultimately depended on the temporal coordination of human activities, in particular their synchronization. The basis for Wiener’s model was provided by his insights into the temporal structures of cerebral processes. This article reconstructs the historical context of Wiener’s ‘brain clock’ hypothesis, largely via his dialogues with John W. Stroud and other scholars working at the intersection of neurophysiology, experimental psychology, and electrical engineering. Since the 19th (...) century, physiologists and psychologists have been conducting experimental investigations into the relation between time and the brain. Using innovative instruments and technologies, Stroud rehearsed these experiments, in part without paying any attention at all to the experimental traditions involved. Against this background, this article argues that the novelty of Wiener’s model relies largely on his productive rephrasing of physiological and psychological findings that had been established long before the Second World War.

Gilbert Simondon's essay Du mode d'existence des objets techniques (1958 [On the mode of being of technical objects]) operates in the transitional space between Heidegger's philosophy of technology and contemporary cybernetics. Furthermore, Simondon outlines an explicitly political program that culminates in the demand to emphasize the status of technical objects in the culture of contemporary society by way of human representatives. The basis for this program is his conception of the technical »thing« as a medium. German Gilbert Simondons Abhandlung Du (...) mode d'existence des objets techniques (1958) operiert im Übergangsraum zwischen Heideggers Technikphilosophie und zeitgenössischer Kybernetik.

In 1923, Paul Valéry created an artificial world of antiquity. In it the sea could wash up things which, because of their brilliance, hardness, and unfamiliar form, interrupted and irritated well-established habits of thought. Nature or art? Given or created? Earthly or heavenly? Eupalinos, the architect, does not find himself in the position to decide. He throws back into the sea the shiny, ball-like thing he had picked up from the shore only seconds before.1 In the 1950s, the situation has (...) changed markedly. Parisian consumer society uses the polished floors of exhibition halls and salesrooms to create encounters with similarly enigmatic and wonderful objects. However, one can no longer take these ..

Marshall McLuhan understood television as a tactile medium. This understanding implied what Bruno Latour might call a ‘symmetrical’ conception of tactility. According to McLuhan, not only human actors are endowed with the sense of touch. In addition, TV, digital computers and other ‘electric media’ use light beams and similar scanning techniques for ceaselessly ‘caressing the contours’ of their surroundings. This notion of tactility was crucially shaped by the holistic aesthetics of the early Bauhaus. To get at the specific features of (...) the TV image, McLuhan relied on the writings of László Moholy-Nagy and Sigfried Giedion, in particular their use of photography for capturing and highlighting the ‘texture’ of surfaces. However, he hardly reflected the social and political factors that, in the age of electric media, contribute to the ‘symmetricization’ of touch. (shrink)

Engaging with the specific ways current media technologies interact with, or directly access the human body, we suggest developing a ‘symmetrical’ theory of touch. Critically referring to Bruno Latour’s invocation of ‘symmetrical anthropology’, we reconsider tactile agency as ‘technological agency’, arguing that the concept of touch – traditionally viewed as an exclusively human ability – should be extended to non-human actors and analysed in view of the cultural logic of capitalism. Its systematic focus, then, is on the productive intersections and (...) contact zones between biology and technology: from phenomena of non-human touch in industrial production to the material touching taking place in the instrumental grasp on the living in the 19th-century physiological laboratories and the invisible operations of tracing, tracking and sensing taking place in the technological milieus of today’s environments. In highlighting the tactile dimension of digital modernity and its economic genealogies, this article aims to advance a combined concept of human and non-human touch which provides a crucial angle for reconsidering bodies and technologies in the age of ubiquitous computing.

With studies like Discourse Networks 1800/1900 and Gramophone, Film, Typewriter, Friedrich A. Kittler contributed significantly to transforming the history of media into a vital field of inquiry. This essay undertakes to more precisely characterize Kittler’s historiographical approach. When we look back on his early contributions to studies of the relationship between literature, madness and truth – among others, his doctoral dissertation on the Swiss poet and writer Conrad Ferdinand Meyer – what strikes us is the significance that Jacques Lacan’s structuralist (...) psychoanalysis had in shaping the orientation of Kittler’s later studies. His intensive engagement with Lacan galvanized Kittler’s concern with the question of sex and/or gender in the evolution of the humanities as well as his concern with the media history of the university. At the same time, Kittler’s reliance on Lacan led him to a kind of history that is interested above all in the internal logic of discourse. As we see, for instance, in Kittler’s anecdotic treatment of 19th-century physiologist Hermann von Helmholtz, this historiography does not involve any original research in archives and/or museums. Rather, it builds upon existing historical accounts and focuses its analyses on the issue of symbolic structures. Instead of investigating the history of the material culture of science and technology, what is thereby ultimately reinforced is a philosophical idealism in which knowledge and paranoia become superimposed in and by means of an ‘original syntax’.
