This chapter advances an innovative framework of political theology in general and its intersection with the German Idealist concepts and archives in particular, arguing for the indispensability of the latter for understanding the Christian-modern condition. The general thrust of this framework is to put into question the legitimacy of the Christian-modern world and its authorities, whether secular or religious. As such, it may be said to reactivate a Gnostic perspective within the political-theological debate, one that refuses the world and its modalities of justification and transcendence. At stake is not only the decoupling of immanence from its equation with the secular world and ungrounding modern forms of sovereignty, but also the subversion of modernity’s (no less than Christianity’s) self-legitimating conceptual narratives. Based on this framework, this essay 1) reconfigures German Idealism as the first speculative attempt to think the (genealogical and conceptual) entanglement of modernity and Christianity in the wake of the Enlightenment and the French Revolution; 2) reconsiders German Idealist conceptions of nothingness, the world, and the absolute as caught between the delegitimating and the theodical tendencies, with special emphasis on the problematics of nihilism and history; and 3) provides an overview of the volume’s contents and interventions.
