Book excerpt: The “formidably brilliant” Žižek considers sexuality, ontology, subjectivity, and Marxian critiques of political economy by way of Lacanian psychoanalysis. If the most interesting theoretical interventions emerge today from the interspaces between fields, then the foremost interspaceman is Slavoj Žižek. In Incontinence of the Void (the title is inspired by a sentence in Samuel Beckett's late masterpiece Ill Seen Ill Said), Žižek explores the empty spaces between philosophy, psychoanalysis, and the critique of political economy. He proceeds from the universal dimension of philosophy to the particular dimension of sexuality to the singular dimension of the critique of political economy. The passage from one dimension to another is immanent: the ontological void is accessible only through the impasses of sexuation and the ongoing prospect of the abolition of sexuality, which is itself opened up by the technoscientific progress of global capitalism, in turn leading to the critique of political economy. Responding to his colleague and fellow Short Circuits author Alenka Zupančič's What Is Sex?, Žižek examines the notion of an excessive element in ontology that gives body to radical negativity, which becomes the antagonism of sexual difference. From the economico-philosophical perspective, Žižek extrapolates from ontological excess to Marxian surplus value to Lacan's surplus enjoyment. In true Žižekian fashion, Incontinence of the Void focuses on eternal topics while detouring freely into contemporary issuesfrom the Internet of Things to Danish TV series.
