"Unlike any other animal, [humans] are ready to die for their beliefs. Monotheists and rationalists regard this as a mark of our superiority. It shows we live for the sake of ideas, not just instinctual satisfaction. But if humans are unique in dying for ideas, they are also alone in killing for them. Killing and dying for nonsensical ideas is how many human beings have made sense of their lives. To identify yourself with an idea is to feel protected against death. Like the human beings who are possessed by them, ideas are born and die. While they may survive for generations, they still grow old and pass away. Yet, so long as they are in the grip of an idea, human beings are what Becker called ‘living illusions’. By identifying themselves with an ephemeral fancy they can imagine they are out of time. By killing those who do not share their ideas, they can believe they have conquered death."
