What, then, is missing in today's social bond, if it is not the big Other?
The answer is clear: a small other which would embody, stand in for, the big Other —a person who is not simply "like the others," but who directly embodies authority. In our postmodern universe, every small other is "finitized" (perceived as fallible, imperfect, "merely human, ' ridiculous), inadequate to give body to a big Other — and, in this way, preserves the purity of the big Other unblemished by its failings.
When, in a decade or so, money will finally become a purely virtual point of reference, no longer materialized in a particular object, this demateralization will render its fetishistic power absolute: its very invisibility will render it all-powerful and omnipresent.
The task of radical politics is therefore not to denounce the inadequacy of every small other to stand in for the big Other (such a "critique" only reinforces the big Other's hold over us), but to undermine the very big Other and, in this way, to untie the social bond the big Other sustains.
Today, when everyone complains about dissolving social ties (and thereby obfuscating their hold over us, which is stronger than ever), the true job of untying them is still ahead of us, more urgent than ever.
Lacan's standard notion of anxiety is that, as the only affect that does not lie, it bears witness to the proximity of the Real, to the inexistence of the big Other; such anxiety has to be confronted by courage, it should lead to an act proper which, as it were, cuts into the real of a situation.
There is, however, another mode of anxiety which predominates today: the anxiety caused by the claustrophobia of the atonal world which lacks any structuring "point," the anxiety of the "pathological Narcissus" frustrated by the fact that he is caught in the endless competitive mirroring of his fellow men (a-a'-a"-a"' . . .), of the series of "small others" none of which functions as the stand-in for the "big Other. "
The root of this claustrophobia is that the lack of embodied stand-ins for the big Other, instead of opening up the social space, depriving it of any Master-figures, renders the invisible "big Other," the mechanism that regulates the interaction of "small others," all the more all-pervasive.
