Jesse Bering has an interesting article on why many people have so much difficulty holding a realistic view of death — why they imagine immortal souls wafting off to heaven, and why they can’t imagine their consciousness ceasing to exist. He’s trying to argue that these kinds of beliefs are more than just the result of secondary indoctrination into a body of myth, but are actually a normal consequence of the nature of consciousness. We never personally experience the extinction of our consciousness, of course, except for the limited loss of sleep — and we always wake up from that (at least, until the last time), so we at least have personal evidence that would inductively imply immortality.
It’s also a set of beliefs that are remarkably pervasive. Our language and culture and habits of thought make the idea of survival after death continually crop up.
