In spite of this impressive progress, however, I still think that we are only at the starting line: many problems remain to be solved before this project can provide guidelines for policy-making. Learned academics may be experts in “explaining” the causes and effects of past events that have shaken the world.
To put it metaphorically, failures in the last war are always scrutinized thoroughly, and their lessons are presented. In contrast, we policy makers should be looking forward into the future. We should not be fighting the last war when things are changing rapidly, no matter how well we may have learned the lessons of the last war.
