“Sadly, in Paul Sabin’s account, the main villain turns out to be the morally upstanding Simon who, fifteen years after his death, is blamed for creating policy logjams and fueling uncivil discourse. In the meantime, Paul Ehrlich keeps issuing ‘important warnings’ such as a recent prediction that humans might soon have to resort to cannibalism to survive the ecological apocalypse.”

The background and story of the famous bet between catastrophist biologist Paul R. Ehrlich and optimist economist Julian L. Simon was first told in some detail over twenty-five years ago by journalist John Tierney in the pages of the New York Times Magazine. The bet, ostensibly on the future prices of five commercially important metals – copper, chromium, nickel, tin, and tungsten – provided a platform upon which two opposing worldviews, that of Ehrlich’s depletionist catastrophism and Julian’s optimistic resourceship, confronted each other.…

This piece was finalized in Simon’s treatise, The Ultimate Resource 2 (1996), pp. 604–607.
