Linda Nicholson's book The Play of Reason: From the Modern to the Postmodern admirably integrates history and philosophy to demonstrate the historical characteristics of reason and arguments in its name. I argue that she nonetheless retains a modernist dependence on the specter of unreason to document the reasonableness of her own positions. This specter continually recreates hegemonic “reasons.” Feminist theory, I argue, should confront more fully its continued dependence on the other of reason.
