This paper is a defense of rationalism and a critique of what I call anti-rationalist themes in postmodernist, feminist and multiculturalist thought. I use the term rationalism in its broad sense to identify an extensive set of philosophic assumptions rooted in the Enlightenment. Rationalism in this sense encompasses the empiricist, materialist and Kantian positions out of which modern analytic philosophy develops In particular, this paper focuses on criticisms that treat rationality and attendant presumptions of objectivity as a Eurocentric form of (...) ethnocentrism. These anti-rationalist concerns are often expressed in prescriptions for multiculturalism and complaints about Western logocentrism and insensitivity to the importance of difference, diversity, attunement, and other. The paperidentifies central themes that reflect this anti-modern and antirationalist temper and argues that each embodies a deep irresolvable philosophic confusion. In developing this critique, I try to show that the Enlightenment project, properly understood, provides the best and most comprehensive groundings for declaiming and remedying the faults of ethnocentrism and prejudice.
