That is the new, forthcoming Žižek book, here is one brief excerpt:
Peter Sloterdijk endorses Badiou’s thesis, from his Le siecle, that the defining feature of the twentieth century was “the passion for the real,” the gravitational pull toward the real basis of our lives (economic base, libido, will, etc.). What we witness is the reversal of the traditional relation between public theology and occult materialism preached in elite circles — today, materialism is public while gnostic theology grows in the underground…Passion for the Real is not just a realist-cynical stance of reducing ideological chimeras to their “actual base” (“it’s all really about the economy, power, sex”), it is also sustained by a messianic logic of extermination: the cobweb of (religious, moral, etc.) illusions has to be ruthlessly erased, and it has to be done now. The twentieth century was a time of extremis, of passage a’ l’acte, not of hope for some future. Sloterdijk, of course, for this very reason sees the twentieth century as the age of extremism and ethical catastrophes, from Nazism to Stalinism.
I have several other of his books in my pile to read; this latest one focuses much of its energy on Lacan and also the Slovenian theorist Alenka Zupančič. It turns out Žižek also is a big fan of Liu Cixin and The Three-Body Problem.
