and others
You mentioned a couple of authors I have not read, who look interesting. I will check them out, although we are a bit limited by libraries remain closed, and I just hope there is no further London lockdown as I don't think many of the bookshops would survive a second full blown lockdown. I do read e-books but do prefer paper books.
I originally started to this thread because there is such a fear of death pervading our culture. However, my initial quest about life after death began when I was a student and got the question 'Is there life after death ?' as an essay title and went on reading on this subject and my views have shifted at various times. I feel that it is the most essential question, perhaps more so than the existence of God, because from a personal perspective, it makes all the difference whether we have one earthly existence or an immortal life. If approached as a philosophical question rather than as part of an established body of religious teachings, it is a big puzzle because we cannot experience death directly.
We have the near death experience accounts but the individuals did not die completely, so they might indicate a possibility of an afterlife but they could have just been dream experiences. If they count for anything they do point to possible dimensions explored in The Tibetan Book of the Dead. However, the Tibetan tradition of Hinduism believed in reincarnation rather one life followed by an immortal existence.
Personally, I would prefer to think that we have many lives because it would give more opportunities for exploring life rather than the limits of one life. But I would not wish to believe it simply because I like it, as the truth is more important than what one would like. Also, there are complications to the idea, such as whether a person could come back as an animal sometimes or, having evolved to the human kingdom, would most likely come back in future lives as another human being.
Having been brought up in a Roman Catholic, and most of my friends are Christians, most of them believe in life after death but are rather vague about this. Within Christian theology there are 2 very different strands of thought: a belief in immortality which was derived from the founding fathers' reading of Plato, and a belief in a resurrection at the end of the world. These two ideas are not necessarily compatible with each other, but I have yet to meet a churchgoers who spends time worrying about this.
As it is, I don't want to spend my whole life pondering the mystery of life after death and not living this one as a result, but I do find it to be a fascinating question. I am not completely convinced that there is life after death but I think it is a possibility. In the meantime, perhaps life and death are two antagonists energies, as Petrichor drew upon, in Freud's suggestion of the conflict between Eros and Thanatos.
