Eschatology is generally understood to be the doctrine of last things, but understood rigorously eschatology actually speaks of the inauguration of a new, redeemed world to come and of the coming of God himself. To speak of eschatology in this way is to speak of the very possibility of the future in the radical sense, the future that is not a mere attenuated variation of presence. Eschatology speaks of a coming that comes only to pass away into a past; rather it speaks of the coming of the Holy itself, which is the very origin of time and is thus the event par excellence. This book attempts to make manifest the question that eschatology itself poses: that eschaton has something essential to do with the beginning. This work intervenes in contemporary debates on "postsecularism" and "the return to religion." By introducing the question of eschatology anew, this book reintroduces the problem of transcendence that effectively calls into question the logic of sovereign power and rethinks the place of ''religion'' as an affirmation of what lies beyond, which does not function as the legitimizing principle of sovereignty in today's world of mass consumption.
