Residential segregation according to race remains fairly entrenched in parts of the United States despite the fact that public attitudes toward racial integration have become dramatically more positive. This incongruity is often explained in terms of the irrationality of agents, whereby the agents’ support of integration is undermined by systematic/unconscious racism. The author argues that such accounts present an implausible model of practical rationality and places too great a justificatory burden on the critic/observer perspective. As an alternative, he suggests the (...) problem is a conflict between modes of practical rationality, specifically, between reasons developed from an embedded context and reasons from a general, abstract perspective. Because many whites live in segregated conditions, they develop contextual reasons for preserving that way of life, even if such reasons fly in the face of their sense of justice. This account is more philosophically sound and gives rise to interesting policy recommendations for overcoming segregation. Key Words: segregation • trust • ideology • practical rationality. (shrink)
