In this essay, Dennis Carlson explores some of the implications of Derrida's "hospitality politics" in helping articulate a progressive response to a rightist cultural politics in the United States of policing national, linguistic, and other borders. He applies the concept of hospitality politics to a critical analysis of the social construction of the "problem" of "illegal immigrants" in U.S. public schools. This entails a discussion of three interrelated discourses and practices of hospitality: a universalistic discourse of philosophical and religious principles, a legalistic-juridical discourse, and a discourse and practice grounded in the ethos of everyday life. Derrida suggested that a democratic cultural politics must interweave these three discourses and also recognize the limitations of each of them. Moreover, a democratic cultural politics must be most firmly rooted in the praxis of ethos, and in the ethical claims of openness to the other.
