"Regular crises perpetuate the past by reinvigorating cycles which started long ago. In contrast, (capital-C) Crises are the past's death knell. They function like laboratories in which the future is incubated. They have given us agriculture and the industrial revolution, technology and the labour contract, killer germs and antibiotics. Once they strike, the past ceases to be a reliable predictor of the future and a brave new world is born."
