    Representation of the Microcosm: The Claim for Objectivity in 19th Century Scientific Microphotography.Olaf Breidbach - 2002 - Journal of the History of Biology 35 (2):221 - 250.
    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 (...)

    The Controversy on Stain Technologies — an Experimental Reexamination of the Dispute on the Cellular Nature of the Nervous System Around 1900.Olaf Breidbach - 1996 - History and Philosophy of the Life Sciences 18 (2):195 - 212.
    The controversy of neuroanatomy on the principal structure of the nervous systems, which took place at the end of the nineteenth century, is described. Two groups of scientists are identified: one that favoured the idea of a discrete cellular organization of the nervous tissue, and one that favoured a syncytial organization. These two interpretations arose from different histological techniques that produced conflicting pictures of the organization of the nervous tissue. In an experimental reexamination of the techniques used at the end (...)

    Lorenz Oken and "Naturphilosophie" in Jena, Paris and London.Olaf Breidbach & Michael Ghiselin - 2002 - History and Philosophy of the Life Sciences 24 (2):219 - 247.
    Although Lorenz Oken is a classic example of Naturphilosophie as applied to biology, his views have been imperfectly understood. He is best viewed as a follower of Schelling who consistently attempted to apply Schelling's ideas to biological data. His version of Naturphilosophie, however, was strongly influenced by older pseudoscience traditions, especially alchemy and numerology as they had been presented by Robert Fludd, whose works were current in Jena and available to him. According to those influences, parts of Oken's philosophical conception (...)

  5. Schattenbilder: Zur elektronenmikroskopischen Photographie in den Biowissenschaften†.Olaf Breidbach - 2005 - Berichte Zur Wissenschaftsgeschichte 28 (2):160-171.
    The paper describes the first attempts of biological electron microphotography. It starts with a description of the early use of electron microscopy in biology, showing that electron microscopy was used as an extension of former light microscopical studies. Thus, the pictures produced by electron microscopy are interpreted as describing the micro-texture of those structures already seen in light microscopy. That was done irrespective from the specific problems of tissue preparation for electron microscopy. The use of photography in electron microscopy is (...)

    Zum Verhaltnis Von Spekulativer Philosophie Und Biologie Im 19 Jahrhundert.Olaf Breidbach - 1985 - Philosophia Naturalis 22 (3):385-399.
    In his study on 'schelling's and hegel's verhaltnis zur naturwissenschaft' of 1844 m j schleiden, one of the leading biologists of that time, opposed the speculative idealism. his work marks the change of the german biology to a science that is founded on materialistic assumptions. it gives the essence of a discussion that is not only interesting in a historical perspective but accentuated an ongoing controversy.

    Eine naturwissenschaftliche Forschungsbibliothek des 18. Jahrhunderts: Die Bibliothek der ‚Naturforschenden Gesellschaft’ zu Jena†.Paul Ziche, Gabriele Büch, Karsten Kenklies, Horst Neuper & Olaf Breidbach - 2000 - Berichte Zur Wissenschaftsgeschichte 23 (4):433-447.
    The ‚Naturforschende Gesellschaft’, founded in 1793, proved instrumental for the development of science at the University of Jena around 1800. Its library can be considered as one of its most important facilities provided for research and for the education of students. Since this library has been preserved almost without losses, we can ask whether this library served the purpose of a research library in the newly established field of ‚science’. In consequence, the role of scientific societies and the genesis of (...)

    In 1889 the Kiel plancton expedition started to perform the first quantitative analysis in marine ecology. The methods performed by this expedition caused an extensive discussion about the suitability of quantitative methods in a study of biological organizations. This discussion outlined the theoretical differences between the two main German schools in zoology: the descriptive morphology as performed by Ernst Haeckel and the analytical physiology as initiated by Emil DuBois-Reymond. The present study describes the positions of both, the morphology and the (...)

  26. Internal Representations--A Prelude for Neurosemantics.Olaf Breidbach - 1999 - Journal of Mind and Behavior 20 (4):403-419.
    Following the concept of internal representations, signal processing in a neuronal system has to be evaluated exclusively on the basis of internal system characteristics. Thus, this approach omits the external observer as a control function for sensory integration. Instead, the configuration of the system and its computational performance are the effects of endogeneous factors. Such self-referential operation is due to a strictly local computation in a network. Thereby, computations follow a set of rules that constitutes the emergent behaviour of the (...)
