Hardt and Negri, from "Marx's Mole is Dead":
Marx tried to understand the continuity of the cycle of proletarian struggles that were emerging in nineteenth-century Europe in terms of a mole and its subterranean tunnels. Marx's mole would surface in times of open class conflict and then retreat underground again - not to hibernate passively, but to burrow its tunnels, moving along with the times, pushing forward with history so that when the time was right (1830, 1848, 1870) it would spring to the surface again. "Well grubbed old mole!"[2] Well, we suspect that Marx's old mole has finally died. It seems to us, in fact, that in the contemporary passage to Empire the structured tunnels of the mole have been replaced by the infinite undulations of the snake. This is the image that Deleuze gives in his analysis of the passage from disciplinary societies to societies of control. (Deleuze claims that contemporary society had gone beyond the disciplinary forms that Foucault analysed. Today the disciplinary institutions, the school the family, the prison, the factory, are all in crisis. This doesn't mean that disciplinary logics are breaking down; what is breaking down rather are the institutional boundaries that once defined and limited their application to one social space. The disciplinary logics spread out across society, they are generalised and in some respects intensified. The generalised disciplinarity is what defines the society of control.) "The old mole", Deleuze writes, "is the animal of closed environments, but the snake is the animal of the societies of control. We have passed from one animal to another, from the mole to the snake, in the regime we live under, but also in our way of living and our relations with others." The depths of the modern world and its subterranean passageways have in postmodernity all become superficial. Today's struggles slither silently across the superficial, imperial landscapes. Perhaps the incommunicability of struggles, the lack of well-structured, communicating tunnels, is in fact a strength rather than a weakness - a strength because all of the movements are immediately subversive in themselves and do not wait on any sort of external aid or extension to guarantee their effectiveness. Perhaps the more capital extends its global network of production and control, the more powerful any singular point of revolt can be simply by focusing their own powers, concentrating their energies in a tense and compact coil, these serpentine struggles striking directly at the highest articulations of imperial order. Empire presents a superficial world, the virtual centre of which can be accessed immediately from any point across the surface. If these points were to constitute something like a new cycle of struggles it would be a cycle defined not by the communicative extension of the struggles but rather by their singular emergence, by the intensity that characterises them one by one. In short, this new phase is defined by the fact that these struggles do not link horizontally but each leap vertically, directly to the virtual centre of Empire.[3] From the point of view of the revolutionary tradition, one might object that the tactical successes of revolutionary actions in the nineteenth and twentieth centuries were all characterised precisely by the capacity to blast open the weakest link of the imperialist chain, that this is the ABC of revolutionary dialectics, and thus it would seem today that the situation is not very promising. It is certainly true that the serpentine struggles we are witnessing today do not provide any clear revolutionary tactics, or maybe they are completely incomprehensible from the point of view of tactics. Faced as we are with a series of intense subversive social movements that attack the highest levels of imperial organisation, however, it may be no longer useful to insist on the old distinction between strategy and tactics. In the constitution of Empire there is no longer an "outside" to power and thus no longer weak links - if by weak link we mean an external point where the articulations of global power are vulnerable. To achieve significance, every struggle must attack at the heart of the Empire, at its strength. That fact, however, does not give priority to any geographical regions, as if only social movements in Washington, Geneva or Tokyo could attack the heart of Empire. On the contrary, the construction of Empire and the globalisation of economic and cultural relationships means that the critical centre of Empire can be attacked from any angle. The tactical preoccupations of the old revolutionary school are thus completely irretrievable; the only strategy available to the struggles is that of a constituent counter-power that emerges from within Empire.
