Influential philosopher Michel Serres's foundational work uses fable to explore how human relations are identical to that of the parasite to the host body. Among Serres's arguments is that by being pests, minor groups can become major players in public dialogue--creating diversity and complexity vital to human life and thought. Michel Serres is professor in history of science at the Sorbonne, professor of Romance languages at Stanford University, and author of several books, including "Genesis." Lawrence R. Schehr is professor of French at the University of Illinois, Urbana-Champaign. Cary Wolfe is Bruce and Elizabeth Dunlevie Professor of English at Rice University. His books include "Zoontologies: The Question of the Animal "(Minnesota, 2003).
