From a brilliant blog, Larval Subjects:
Perhaps the conception of community I'm trying to think about-- without much success --can aptly be summed up in the idea of a community without One, where the One might be thought as the master-signifier unifying the identity of difference, or the logic of masculine sexuation.
In accord with this theme, Reinhard, Santner, and Zizek suggest in their different contributions to The Neighbor that the feminine formulae of sexuation might be useful here. Reinhard, as far as I recall, emphasizes the non-All primarily as a supplement. Zizek, although often hinting in this direction, tends to focus more on the discourse of the analyst as suggesting an alternative social link.
When I try to think community in terms of non-All, I end up thinking primarily in terms of lacks, spaces, and revisions, a moving community without limits or borders. But then I get stuck in the sense that this is no community at all, that there is nothing that links members other than a kind of formal absense or suspension. I end up, in other words, in a not particularly useful version of the discourse of the analyst. I think over the next few days I'm going to go through the posts at Larval Subjects--there are excellent discussions of Lacan and Deleuze that might help me think better about these matters.
