The ArgumentEtienn-François Geoffroy' Table des Rapports is generally regarded as a landmark in the evolution of chemistry during the eighteenth century. Issues have arisen among historians concerning the significance and originality of the Table that require fuller attention to the immediate context of chemical research in the Academie des sciences during the two decades that preceded its appearance. The present paper argues that, despite the transition from communal to individual research projects that marked the reorganization of the Academy in 1699, (...) chemists continued to pursue shared problems within a communal ethos. The interactions between Wilhelm Homberg, Etienne-François Geoffroy, and Louis Lemery were particularly prominent. The paper traces one example of this interaction, involving the sulfur principle and its influence on one entry in Geoffroy's Table. Further such studies are needed to elucidate the relation between the concepts of chemical composition and reactions implied in Geoffroy's table and the concepts embodied in the previous work of Geoffroy and his associates in the Academy.

In his book "Organic Chemistry in its Application to Agriculture and Chemistry." Justus Liebig attacked "the plant physiologists" for their support of the humus theory and for their general ignorance of chemistry. Two leading botanists, Matthias Schleiden and Hugo von Mohl, responded by sharply criticizing Liebig for his lack of knowledge of plants and his misrepresentation of the views of plant physiologists. The origin and character of this debate can be understood in part through the temperaments of Liebig and Schleiden, (...) but can be viewed also as a contest for control between the well-established discipline of chemistry and a potential discipline of plant physiology that had as yet acquired no stable institutional foundations.

Purpose With the increasing sophistication of neuroimaging technologies in medicine, new language is being sought to make sense of the findings. The aim of this paper is to explore whether the brain-reading metaphor used to convey current medical or neurobiological findings imports unintended significations that do not necessarily reflect the genuine findings made by physicians and neuroscientists. Methods First, the paper surveys the ambiguities of the readability metaphor, drawing from the history of science and medicine, paying special attention to the (...) sixteenth through nineteenth centuries. Next, the paper addresses more closely the issue of how metaphors may be confusing when used in medicine in general, and neuroscience in particular. The paper then explores the possible misleading effects associated with the contemporary use of the brain-reading metaphor in neuroimaging research. Results Rather than breaking new ground, what we see in current scientific language is a persistence of both a constraining and expansive set of language practices forming a relatively continuous tradition linking current neuroimaging to past scientific investigations into the brain. Conclusions The use of the readability metaphor thus carries with it both positive and negative effects. Physicians and neuroscientists must resort to the use of terms already laden with abstracted meanings, and often burdened by tradition, at the risk of importing through these words connotations that do not tally with the sought-after objectivity of empirical science.

Oliver Wendell Holmes, Jr, is considered by many to be the most influential American jurist. The voluminous literature devoted to his writings and legal thought, however, is diverse and inconsistent. In this study, Frederic R. Kellogg follows Holmes's intellectual path from his early writings through his judicial career. He offers a fresh perspective that addresses the views of Holmes's leading critics and explains his relevance to the controversy over judicial activism and restraint. Holmes is shown to be an original (...) legal theorist who reconceived common law as a theory of social inquiry and who applied his insights to constitutional law. From his empirical and naturalist perspective on law, with its roots in American pragmatism, emerged Holmes's distinctive judicial and constitutional restraint. Kellogg distinguishes Holmes from analytical legal positivism and contrasts him with a range of thinkers. (shrink)
