I have commented that every belief in survival after death I've come across is either the product of confused thinking, or subverts my understanding of morality, which is about doing something for nothing, and generally gets in the way of appreciating and loving the world we live in as it is.
I want to argue that life after death makes Christianity (the religion I know best) and morality (as I understand it) impossible.
One principle I'd like to explore is that beliefs in an afterlife are unsatisfactory religiously speaking insofar as they are rooted in a desire for more of selfhood rather than more of God. They seek to satisfy an anxiety that my life might be meaningless without its continuance to a fulfilment beyond death; as if life is not worth living, and good not worth doing, unless it can be justified by post-mortem events.
There has never been convincing evidence that 'we' can survive the dissolution of 'our bodies'. There is an important sense in which we are our bodies. Still, the reputation of many psychical researchers have been dashed in the attempt to produce evidence for the existence of non-material bodies. No such 'subtle bodies' have ever forced themselves upon the attention of physical scientists, however sensitive the apparatus they have deployed.
Perhaps though my essential self has nothing to do with bodily existence at all. Perhaps it is to be found elsewhere. Perhaps a dualistic solution should be sought.
