There is no such thing as postmodern— at least not from the perspective of postmodernity. The will to take different things, group them together, and assign them one identity is precisely the will postmodernity critiques.
Postmodernity — whatever that is — is often accredited with undoing truth and the subject. But this is a simplistic reduction. Just as there are individual thinkers with individual world views — Deleuze is not Derrida is not Foucault is not de Certeau is not Guattari — there are different ways of constructing the individual.
Which is to say, just because one might suggest that there is no subject per se — that is, a subject that is self-identical, univocal, and metaphysical (an invisible Being) — does not mean that one is suggesting that there is no form, no identity at all. That would be silly.
The question is not whether there is a subject or not but in what ways can we conceive of the individual.
For instance, why not an individual that is always becoming? Becoming is not the eradication of borders; it's the putting on motion of borders. To consider the individual as a becoming rather than a being is to move the individual from geometry to calculus, from stasis to motion.
A becoming, then, is stipulated, a shaping, a trajectory: I go like this. Like what? Like this.
Let's begin, then, by considering the individual a differential equation: limited but infinite.
And why not networked? Just because I am made of different things, just because I am intersected by threads from elsewhere, doesn't mean I am not singular? I am this node.
Yet I am not just not a node. I am a productive cog: I make sense of these diverse threads in this way. Because I am a thread, too — a shaping of this world, an ever-moving zone of the cosmos, at once constitutive and constituent.
So just because I am not a fixed Being doesn't mean I am not me: I am this becoming node, this inflection of the cosmos.
