Open societies are always endangered. This is especially true of America and Europe today, as a result of the terrorist attacks in Paris and elsewhere, and the way that America and Europe, particularly France, have reacted to them.
Jihadi terrorists, like the Islamic State (ISIS) and Al Qaeda, have discovered the Achilles heel of our Western societies: the fear of death. By stoking that fear through horrific attacks and macabre videos, the publicists of ISIS awaken and magnify it, leading otherwise sensible people in hitherto open societies to abandon their reason.
Brain scientists have discovered that emotion is an essential component of human reasoning. That discovery explains why jihadi terrorism poses such a potent threat to our societies: the fear of death leads us and our leaders to think – and then behave – irrationally. Project Syndicate
