The theme of the 6th biennial Radical Philosophy Association Conference, held at Howard University in Washington, D.C. in November 2004, was "Philosophy Against Empire." The U.S. imperial project, pursued by both Republican and Democratic administrations, has many dimensions, including military force and the mechanisms for its legitimation; the global economy and flows of money and people across borders; and biopolitics, or the disciplining of bodies through the micro-mechanisms of power apart from traditional forms of sovereignty. These issues are explored in depth in these collected and revised essays from the Conference, along with the forms of subjectivity that can resist and respond to the alienation produced within and by the imperial project, toward the creation of an alternative global order.
