out that this is not the way individuals in the complex insect society know what to do. It is not a hierarchical system, they don't receive orders the way soldiers do in an army. The amazing organisation of an anthill 'emerges' from the bottom up, in a collective demonstration of each ant's evolved instincts. In a sense, it is not organised at all since there is no central bureaucracy. The collective behaviour of the colony is an emergent phenomenon.

Likewise, the slime mould growing in damp fields and forests all around us can exhibit remarkably coordinated behaviour. Most of the time, the sludge-like collection of microorganisms go about their business quite independently of one another, each one foraging for food and moving about on its own. But when conditions worsen, food becomes scarce or the forest floor becomes dry, the formerly distinct creatures coalesce into a single being. The large mass of slime moves about, amassing the moisture of the collective, until it finds a more hospitable region of forest, and then breaks up again into individual creatures. The collective behaviour is an emergent trait, learned through millennia of evolution. But it is only activated when the group is under threat. The processes allowing for these alternative strategies are still being scrutinised by scientists, who are only beginning to come to grips with the implications of these findings in understanding other emergent systems from cities to civilisations.

At first glance, the proposition that human civilisation imitates the behaviour of slime mould is preposterous, an evolutionary leap backwards. An individual human consciousness is infinitely more advanced than that of a single slime mould micro-organism. But coordinated human metaorganism is not to be confused with the highly structured visions of a 'super organism' imagined in the philosophical precursors to fascism in the 19th and 20th centuries. Rather, thanks to the feedback and iteration offered by our new interactive networks, we aspire instead towards a highly articulated and dynamic body politic: a genuinely networked democracy, capable of accepting and maintaining a multiplicity of points of view, instead of seeking premature resolution and the oversimplification that comes with it.

This is why it appeared that the decision to grant the public open access to the internet in the early 1990s would herald a new era of teledemocracy, political activism and a reinstatement of the collective will into public affairs. The emergence of a networked culture, accompanied by an ethic of media literacy, open discussion and direct action held the promise of a more responsive political system wherever it spread.
