Since the 1980s, several studies of visual perception have persuasively argued that important aspects of human vision are best accounted for not by recourse to inner mental representations but rather through socially observable actions and behaviors (e.g. Lynch 1985, Latour 1986, Lynch 1990, Goodwin 1994, Goodwin 1997, Sharrock & Coulter 1998). While there are clearly physiological mechanisms required for vision, psychological accounts of perception in terms of inner mental representations have been dislodged from their position as the basic term in (...) the interface between human beings and their environment and replaced with terms such as "social practice," and "vernacular intelligibility." The focus for these .. (shrink)

Historians have often described embryology and concepts of development in the period around 1800 in terms of “temporalization” or “dynamization”. This paper, in contrast, argues that a central epistemological category in the period was “rhythm”, which played a major role in the establishment of the emerging discipline of biology. I show that Caspar Friedrich Wolff’s epigenetic theory of development was based on a rhythmical notion, namely the hypothesis that organic development occurs as a series of ordered rhythmical repetitions and variations. (...) Presenting Christian Heinrich Pander’s and Karl Ernst von Baer’s theory of germ layers, I argue that Pander and Baer regarded folding as an organizing principle of ontogenesis, and that the principle’s explanatory power stems from their understanding of folding as a rhythmical figuration. In a brief discussion of the notion of rhythm in contemporary music theory, I identify an underlying physiological epistemology in the new musical concept of rhythm around 1800. The paper closes with a more general discussion of the relationship between the rhythmic episteme, conceptions of life, and aesthetic theory at the end of the eighteenth century. (shrink)
