Abstract

Picturing Knowledge is a collection of papers on scientific illustration written by historians and philosophers of science. While the philosophers of science tend to focus on the question whether illustrations are more than helpful aids to symbolic proofs and linguistic explications, the historians are interested in the presuppositions attaching to particular modes of representation—the decision what to depict and how to depict it. David Knight discusses the conventions determined what were appropriate and relevant illustrations for textbooks of chemistry. He calls attention to their increasing depersonalization, as pictures of the alchemical laboratory with its furnace and flasks, and then of elegantly clad, unmussed aristocrats gave way to pictures of molecules. Robert J. O’Hara shows how metaphysical assumptions about the organization of nature, in particular the assumption that there existed a system of visible analogies and correspondences across groups of plants and animals, persisted from Linnaeus’s time even into post-Darwinian biology. Stephanie Moser argues that artists’ depictions of australopithecine hominids in semi-popular illustrated magazines of the 1940s and 1950s first reflected, but then entrenched, a view of their mode of life featuring nuclear families, wooden clubs, and homey caves, subsequently rejected as improbable. Other historians investigate the history and problems of scientific representation itself. Bert Hall provides a brief survey of botanical, anatomical, and mechanical illustration, and considers the competing demands of elegance and informativeness. Martin Kemp considers the very different requirements of anatomical and astronomical depictions. Anatomical illustration lends itself to what he calls a “rhetoric of reality” aimed at convincing the viewer that the illustration is what he would see inside an actual human body, while astronomical illustration is unconcerned with the appearances of the heavens, and is a translation of measurements into a scheme representing what cannot literally be seen.
