It is now 32
years, nearly a third of a century, since Julian Simon nailed his theses to the
door of the eco-pessimist church by publishing his famous article in
Science magazine: “resources, population, environment: an oversupply of bad
news”. It is also 40 years since The Limits to Growth and 50 years since
Silent Spring, plenty long enough to reflect on whether the world
has conformed to Malthusian pessimism
or Simonian optimism.
Before I go on,
I want to remind you just how viciously Simon was attacked for saying
that he thought the bad news was being exaggerated and the good news
downplayed. Verbally at least Simon’s treatment was every bit as rough as
Martin Luther’s. Simon was called an imbecile, a moron, silly, ignorant, a
flat-earther, a member of the far right, a Marxist. “Could the
editors have found someone to review Simon’s manuscript who had
to take off his shoes to count to 20?” said Paul Ehrlich.
Erhlich together
with John Holdren then launched a blistering critique, accusing Simon of lying
about electricity prices having fallen. It turned out they were basing their
criticism on a typo in a table, as Simon discovered by calling the table’s
author. To which Ehrlich replied: “what scientist would phone the author of a
standard source to make sure there were no typos in a series of numbers?”
Answer: one who
likes to get his facts right.
