It has to do with activity and passivity. This does not mean one will get there. There is a closure which does not close us off but which,while leaving us open encloses us. The incalculability of these signs prevents them from being valid currency in the phallic exchange. In the economy of phallic representation skin does not count, it functions as a material support.
Skin is screen.
Yet it really is a fear that we will lose touch with parts of ourselves. They fundamentally alter the relationship of the signified to the signifier. Carrying the instabilities implicit in Lacanian floating signifiers one step further, information technologies create what I call flickering signifiers, characterized by their tendency toward unexpected metamorphoses, attenuations, and dispersions. The fear of losing the world is a fear of dismemberment, we close ourselves off into the zipped, conservative ground of the male gaze and colonial vista alike. Against such a fear of loss there is the countervailing play of surfaces, the joy of several worlds at once, passing and multiple.
