Philosophers and scientists have long been interested in how the mind processes the inevitability of death, both cognitively and emotionally. One would expect, for example, that reminders of our mortality—say the sudden death of a loved one—would throw us into a state of disabling fear of the unknown. But that doesn’t happen. If the prospect of death is so incomprehensible, why are we not trembling in a constant state of terror over this fact?
Psychologists have some ideas about how we cope with existential dread. One emerging idea—”terror management theory“—holds that the brain is hard-wired to keep us from being paralyzed by fear. According to this theory, the brain allows us to think about dying, even to change the way we live our lives, but not cower in the corner, paralyzed by fear. The automatic, unconscious part of our brain in effect protects the conscious mind.
But how does this work?
