Considering our afterlives, or lack thereof

Continuing slowly through that Ursula Goodenough book (mentioned in another thread). She runs into this human condition of seeing the universe as mysterious. We evolved without understanding quantum physics. We survived without knowing the size of the universe. But now we have some idea of that, or at least we know that someone can calculate it, and we are slowly evolving the ability to trust that those calculations are true. She bridges this with the term “religious naturalist”, which I think means that she accepts the belief that all these mysteries can be explained naturally. Whether or not they actually are, or even ever will be is a separate issue.
