That topic needs no explanation, but maybe it needs some context. When asked what he thought of the French Revolution, Mao Zedong had famously replied – “It is too early to tell”. People who take a long view of history, like Mao, take the position that it is just too soon to draw the lessons of the crisis.
Policy practitioners do not have the luxury of historians; they have to respond to unfolding developments in real time, and incorporate the lessons of experience. There is another reason why it is not too soon to be talking about the lessons of the crisis; indeed why we should be more activist in learning the lessons of the crisis.
