Methodological Issues

Janice Moulton's "A Paradigm of Philosophy:  The Adversary Method" discusses some of the problems inherent in competitive approaches to argument.  The article can be found in Discovering Reality: Feminist Perspectives on Epistemology, Metaphysics, Methodology, and Philosophy of Science , edited by Sandra Harding and Merrill B. Hintikka (Boston : D. Reidel, 1983) pp. 149-164.  This book is available in our library; the call number is HQ1154 .D538 1983.

Joyce Trebilcot's "Ethics of Method:  Greasing the Machine and Telling Stories"  tells how she finds stories useful for communicating insights in a way that doesn't methodologically maintain the machinery of dominant white western male capitalist culture.  It can be found in Feminist Ethics, edited by Claudia Card (University Press of Kansas,  1991), pp. 45-51).
