ABSTRACT
If time is the most valuable resource each of us has, why should anyone, other than a history buff, allocate several hours a week for a semester, or even two, to become acquainted with the ideas of thinkers long dead? One of the most insightful answers to this question came from John Maynard Keynes who once wrote ‘Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist.’1
