This article suggests that Buber's idea of the community may hint at an alternative to the more common foundations of political thought, usually grounded on notions of power or rationality. Showing how Buber's idea of the community developed from a neo-romantic form (in his early writings) to a principle informed by the dialogical dimension of human life (from I and Thou onwards), I will point out the vertical dimension of political life ensuing from Buber's discourse. A discussion of the theopolitical (...) principle as expressed in Buber's Kingship of God will lead to the conclusion that, both descriptively and normatively, politics needs an openness to transcendence.
