In the early nineteenth century, a group of German biologists led by Johann Friedrich Blumenbach and Karl Friedrich Kielmeyer initiated a search for laws of biological organization that would explain the phenomena of form and function and establish foundations for a unified theory of life. The tradition spawned by these efforts found its most important spokesman in Karl Ernst von Baer. Timothy Lenoir chronicles the hitherto unexplored achievements of the practitioners of this research tradition as they aimed to place functional (...) morphology at the heart of a new science, which they called "biology." Strongly influenced by Immanuel Kant, the biologists’ approach combined a sophisticated teleology with mechanistic theories and sparked bitter controversies with the rival programs, mechanistic reductionism and Darwinism. Although temporarily eclipsed by these two approaches, the morphological tradition, Lenoir argues, was not vanquished in the field of scientific debate. It contributed to pathbreaking research in areas such as comparative anatomy, embryology, paleontology, and biogeography. Preface Introduction 1. Vital Materialism 2.

Georges Canguilhem is one of France's foremost historians of science. Trained as a medical doctor as well as a philosopher, he combined these practices to demonstrate to philosophers that there could be no epistemology without concrete study of the actual development of the sciences and to historians that there could be no worthwhile history of science without a philosophical understanding of the conceptual basis of all knowledge. A Vital Rationalist brings together for the first time a selection of Canguilhem's most (...) important writings, including excerpts from previously unpublished manuscripts and a critical bibliography by Camille Limoges. Organized around the major themes and problems that have preoccupied Canguilhem throughout his intellectual career, the collection allows readers, whether familiar or unfamiliar with Canguilhem's work, access to a vast array of conceptual and concrete meditations on epistemology, methodology, science, and history. Canguilhem is a demanding writer, but Delaporte succeeds in marking out the main lines of his thought with unrivaled clarity; readers will come away with a heightened understanding of the complex and crucial place he holds in French intellectual history.

A complete, illustrated survey of Etienne-Jules Marey's work that investigates the far reaching effects of her inventions on stream-of-consciousness literature, psychoanalysis, Bergsonian philosophy, and the art of cubists and futurists.

The ArgumentThis paper is concerned with the diversity of microscopic research in nineteenth-century life sciences. It examines how two researchers, Ernst Wilhelm Brücke and Heinrich Müller, investigated the structure and function of the retina. They did so in significantly different ways, thereby developing quite different accounts of this organ and its role in the process of vision. Both investigators were carrying out microscopic investigations, both were particularly concerned with interpreting their findings in terms of physiological function, and both employed the (...) physical sciences in their microscopic research. Their approaches differed, however, with respect to the manner of handling and preparing the tissues, as well as with respect to the conceptual tools they applied to their findings.The cases indicate that the common tendency to associate microscopic research mainly with morphological studies of organic material is not appropriate. To understand nineteenth-century microscopy and its place in the sciences of life, close attention should be paid to the manner in which microscopic investigations were performed. It is only then that the flexibility and versatility of microscopic research comes into view. (shrink)

The ArgumentIt is often assumed that all sciences travel the path of increasing precision and quantification. It is also assumed that such processes transcend the boundaries of rival scientific disciplines. The history of the personal equation has been cited as an example: the “personal equation” was the name given by astronomers after Bessel to the differences in measured transit times recorded by observers in the same situation. Later in the nineteenth century Wilhelm Wundt used this phenomenon as a type for (...) his experiments on reaction times. For historians of psychology, this has been taken to be an exemplary case where quantified laboratory science rescued astronomy by showing that this was really a psychological phenomenon measurable only in complication experiments. This paper challenges this story. Astronomers neither ignored, nor despaired of, the personality problem. Instead, the managers of the great observatories developed a new chronometric regime of vigilant surveillance of subordinate observers. The astronomers' solution was thus intimately connected with social and material changes in their way of life: a division of labor in the observatories, a network of observing sites, a mechanization of observation. The paper documents these changes and then presents a study of one case where managers, amateurs, and psychologists clashed for authority over the personality problem. Measurement is given its meaning when situated in specific contexts of styles of work and institutions. Disciplines give meanings to values, and often resist attempts by others to redefine these meanings or to gain authority over measurement. Quantification is not a self-evident nor inevitable process in science's history, but possesses a remarkable cultural history of its own. (shrink)

In this remarkable book Michel Foucault, one of the most influential thinkers of recent times, calls us to look critically at specific historical events in order to uncover new layers of significance.

Microphotography was one of the earliest applications of photography in science: The first monograph on tissue organization illustrated with microphotographs was published in 1845. In the 1860s, a large number of introductions to scientific microphotography were published by anatomists. They argued that microphotography was a means of documenting the results of microscopic analysis, uncontaminated by the subjectivity of the observer. In the early decades of the 19th century, before the general acceptance of cell theory, such a technique was of special (...) importance, as no criteria were available to distinguish between important and superficial characters in the description of tissue microstructures. Microphotography was praised as the method of choice for documenting the scientific observations of microscopic material. Some of the microphotographic practices described in these early manuals, however, did not conform with the idea of a purely mechanical process of documentation. The authors of these manuals saw photography not as a technique which produced artifacts, but as a complete and reliable substitute for the original preparations. Thus, according to these authors, the artificial world of photography was seen as the actual representation of the microworld. Consequently, they tried to understand the microcosm by analyzing photographs instead of the microscopic preparation themselves. Such attitudes discredited the use of microphotography in the sciences. Consequently, the definitive breakthrough of scientific microphotography was delayed until the 1880s and was largely due to the efforts of Robert Koch, who made microphotography a central tool of bacteriology.
