In Massumi’s user’s guide to Capitalism and Schizophrenia , he writes:
First of all, it wouldn’t take much to recognize the connection between this and Sartre’s existentialism. It is, even if Deleuze doesn’t recognize it, testimony to the freeing power of the underlying nothing and the nihilistic perspective that spontaneously emerges from it. It recognizes, as Sartre did, that the nothingness between ourselves at any given moment, the self we could be 5 minutes down the line, opens us to any number of possibilities. The primary difference is that Deleuze seems to have blind spot for the angst and vertigo of possibility that can result from that condition.
But more important, this plays into and was stated in the context of Deleuze’s notion of the virtual: that which refers to the experienced now, which is not really experienced since we’re always tilted toward future possibilities or leaning back to the past. In other words: there is no now, only an assumed one. (Kind of accommodates Dennett’s spacio-temporal smear, doesn’t it?) This state serves as a foundation for all our potentials and possibilities.
And, in this sense, I get Deleuze’s embrace of the virtual for same reason I embrace the nihilistic perspective. They’re both equivalent as far as I’m concerned. At the same time, as I have said before: the nihilistic perspective is a nice place to visit; but only a sociopath or psychotic would want to live there. And this lies at the heart of my issue with Deleuze.
The sociopathic pitfall of the nihilistic perspective and the virtual is defined by those who, having no real criteria to regulate their behavior, turn to the one criterion that has a kind of praxis to it: power. Their basic argument is circler in nature:
I have power because I am right. Therefore, I am right because I have power.
This, of course, is the tautology of the serial killer, cut-throat capitalists, and players.
The psychotic, on the other hand, is a strategy of retreat. What they do is immerse themselves in their own little semiotic bubble with its own system of signs and rules of usage to the extent of becoming useless to the general symbolic order. This, at its most ideal, is the crazy-person walking down the street engaging in their own dialogue with an imagined listener. But in more watered down forms, it is the domain of drug and alcohol addicts, as well as, unfortunately, the avant garde and, to a great extent, Deleuze.
