In this collection of Taubes's writings on Schmitt, which includes decades of letters, reflections, and musings, the two intellectuals explore ideas of the apocalypse and other central concepts of political theology. In these writings, a sharper, more nuanced portrait of Schmitt's thought emerges, as well as a more complicated understanding of Taubes, who shaped the work of Giorgio Agamben, Peter Sloterdijk, and other major twentieth-century theorists.
