In the book ‘Emergence’ 2002 Steve Johnson refers to the slime mold (Dictyostelium discoideum) to illustrate the term emergence. The slime mold spends a great part of his life as thousands of independent single cells called units; each unit behaves independently of the rest. When the environmental conditions are hostile, the slime mold acts as a single organism; when there is a large food supply, as Johnson writes, ‘it’ becomes a “they”’(Johnson, 2002, 13). Researchers began by looking for pacemaker cells (cells that would command and organise other cells). Nevertheless, the data was not showing evidence of the existence of any ‘pacemakers’. The theoretical model that looked for the ‘pacemakers’ cells is coherent with an idea that explains our actions as being governed by the notion of a ‘pacemaker’. It does not matter if they come in the form of the brain as the ‘peacemaker’ of the body, nor as kings, dictators, gods, presidents, or city councilmen as pacemakers of our social organisations. Evelyn Fox Keller, a mathematician studying ‘non-equilibrium thermodynamics’, showed in 1969 that the idea of a ‘pacemaker’ was wrong. Fox Keller argued that the organisation that allowed the shift from the ‘they’ to the ‘if’ of the mold—rather than being a centralised process—was a collective behaviour: an ‘in between relation’. ‘Cells would begin following trails created by other cells, creating a positive feedback loop that encourage more cells to join the cluster. [...] then the large smile mold community might well be able to aggregate based on global changes in the environment—all without a pacemaker cell calling the shots ‘(Johnson, 2002, 16).
