Many resources financial and emotional as well as intellectual have contributed to the completion of this project, which is a revised version of my dissertation. I am grateful to Emory University for the funding provided during my five years of graduate study. Beyond its monetary contributions, I also want to recognize the collegia 1 environment that is intentionally cultivated at Emory. My education and development as a scholar have benefited greatly from the lack of competition between students for financial resources, attention to interdisciplinary engagement, and an institutional environment in which scholarly disagreement is not necessarily acrimonious.
