It’s been over a month since the armed assault on the Charlie Hebdo offices in Paris, and the tragedy has been on my mind every day since. There are many issues deserving reflection, from free speech versus hate speech, rising xenophobia and violent extremism, or even avoiding the conflation of all Muslims with the violently radical, yet tiny network of heretics. Yet, my mind has been preoccupied with a more overarching theme of the core mission of terrorism – terror itself. The goal is more than a body count; it’s the arousal of our most instinctual response in evolutionary psychology: fear, and where that fear will likely lead us.
