Absolutely. I am disappointed in Zizek’s formulations thus far of the movement, his solidarity is admirable, but also of course predictable. His trying to instill some sort of feeling of unity and direction among the movement is weak since he gives no positive values to the movement, he only backs them up in their “no!”. We need “no!”, certainly! But we also need so much more than this. As you say, the movement will not become relevant (for the/a future) until it becomes philosophical, able to clearly posit itself as a valuing/s counter to the present system and its values. This is not easy work, of course. I must devote some time to thinking on how we may aid the movement toward this end, for certainly it is in need of such assistance.
One possible venue for influence would be the magazine Adbusters from which the movement originated. They take a lot of submissions from readers and unsolicited material. A well-timed and well-developed delineation of the movement and issues/stakes involved from the perspective of value ontology might prove massively effective in the long run. Certainly we do not need any more Zizek’s standing around trying to keep things from falling apart without ever seeing how the entire movement lacks a basis upon which it might continue and grow into something significant. Neo-marxism indeed is insufficient here, but we might borrow from it here or there, even re-use some of its notions in a newer and more useful light.
Of course another concern is that there ARE conter-values, more positive ones, out there, as you say within the more individual levels of the movement, and elsewhere. These positive valuations remain generally diffuse and isolate, mere particulars unable to gain control of a larger unit, unable to designate terms common to some milieu. Spreading these notions would be a first necessary step to establishing a fertile soil from which seeds might be sown later on.
