This book is not an attack on the many healthy uses of logic or reason, but it is an attack on a dangerous kind of logical overreach, which demands that every solution should have a convincing rationale before it can even be considered or attempted. If this book provides you with nothing else, I hope it gives you permission to suggest slightly silly things from time to time. To fail a little more often. To think unlike an economist. There are many problems which are logic-proof, and which will never be solved by the kind of people who aspire to go to the World Economic Forum at Davos.
