The female characters in the Br̥hadāraṇyaka Upaniṣad have generally been interpreted by scholars in two opposing fashions: as fictional characters whose historicity can be dismissed or as representative of actual women in ancient India. Both of these interpretations, however, overlook the literary elements of this text and the role that these female characters play within the larger philosophical debate. This paper is an analysis of the various women who appear in the Br̥hadāraṇyaka and their role in this text. Close attention (...) is paid to their characterizations, their relationship to the doctrine discussed, and their functions in the larger narrative structure. The paper concludes with a discussion about the relationship of narrative to history and fundamental problems with the “woman question” based on this text. (shrink)

Recent work on the heat-shock protein Hsp90 by Rutherford and Lindquist (1998) has been included among the pieces of evidence taken to show the essential role of developmental processes in evolution; Hsp90 acts as a buffer against phenotypic variation, allowing genotypic variation to build. When the buffering capacity of Hsp90 is altered (e.g., in nature, by mutation or environmental stress), the genetic variation is "revealed," manifesting itself as phenotypic variation. This phenomenon raises questions about the genetic variation before and (...) after what I will call a "revelation event": Is it neutral, nearly neutral, or non-neutral (i.e., strongly deleterious or strongly advantageous)? Moreover, what kinds of evolutionary processes do we take to be at work? Rutherford and Lindquist (1998) focus on the implications of non-neutral variation and selection. Later work by Queitsch, Sangster, and Lindquist (2002) and Sangster, Lindquist, and Queitsch (2004) raises the possibility that Hsp90 buffering may play the role that was played by drift in Sewall Wright's shifting balance model, permitting transition from one adaptive peak to another. However, Ohta (2002) suggests that much of this variation may be nearly neutral, which in turn, would imply a strong role for drift as well as selection. The primary goal of this paper is to illuminate the alternative scenarios and the processes operating in each. At the end, I raise the possibility of a synthesis between evo-devo and nearly neutral evolution. (shrink)
