The Guardian today issues us all with a challenge to think outside the box when we search for answers to the financial crisis: "The Greek word kairos is the origin of the word chaos, but for the ancient Greeks it also described how some moments of crisis are decisive - they offer both danger and opportunity. They are moments that require courage and boldness of judgment. Roosevelt grasped that point of kairos in 1933, and produced his New Deal.

Something comparable from our politicians may be necessary in the next 18 months when tinkering with the system proves insufficient to restart the UK economy. They could set the tanker on a new course, and it could be a much better direction of travel with a more credible definition of wealth creation and the good life."
