Ernest Becker said, “The last thing a man can admit to himself is that his life-ways are arbitrary: This is one of the reasons that people often show derisive glee and scorn over the strange customs of other lands—it is a defense against the awareness that his own way of life may be just as fundamentally contrived as any other. One culture is always a potential menace to another because it is a living example that life can go on heroically with a value framework totally alien to one’s own.” (The Denial of Death)
What is Becker saying? I would sum it up like this: We have our own cultural worldviews, things we collectively believe in that sustain us and stave off death anxiety. When we see “the other"—other cultures or ways of being—it threatens our own. That threat creates doubt, and that doubt awakens death anxiety.
That’s why it’s so important to recognize the aggression you feel toward people who are different. This is the birthplace of those emotions. When I talk about these theories being critical, this is one that is at the top, or near the top, of the list. It’s vital to be conscious of our death anxiety and how we manage it.
