The question I want to ask then is: The liberal turn we've seen in the latter half of the last century, is that just a consequence of people managing to push away thinking of death a lot better?

Or have we, like Christovir's Quakers, managed to turn our fear of death into something positive? FWIW, I know they exist, people who simply become even better people when they arguably should be afraid. I've met a few, but not many. So I am indeed worried that a great deal of everyday humanism and liberalism may be poorly rooted.
