A capacity to accommodate fragility, he says, is a fundament of vital, evolving systems, whether geological or human. At the right temperatures, geologic faults allow for movement, ductility, flow. Earthquakes happen when weaknesses cannot be expressed. “And communities which are rigid, which do not take into account the weak points of the community—people who are in difficulty—tend to be communities that do not evolve. When they do evolve, it’s generally by a very strong commotion, a revolution.”
