A science [economics] that can describe minute changes in the price of a bushel of corn does not even try to place a value on any aspect of human welfare. To the old economists, surplus corn warehoused in silos is more valuable than all of the lives saved by avoiding a war. Because they are unable to place an exact value on human life and happiness, as you can on a bushel of corn, the old economists don't even try to give it any value at all. And they blithely dismiss those who do.
