Slavoj Žižek often refers to an obscene excess-supplement that, depending on the subject’s pathological disposition, serves to either 1) sustain a conscious injunction by disavowing an unconscious “underside” or 2) instruct the subject to transgress the injunction. This supplemental excess is at work in neurotic and perverse belief but functions in significantly different modes depending on whether the supplement affects the ego or superego. This paper surveys and analyzes Žižek’s use of the obscene excess-supplement in his theological and political applications (...) of psychoanalytic theory. (shrink)
