Alianora reflects that flesh sags with age and that:
"The earth dragged you down towards it, and then it dragged you down into it, and then...you found out for sure what came afterwards." (p. 42)
We only find out what comes afterwards if something comes afterwards. Otherwise, we know nothing. Lazarus Long's supposedly wise Notebooks make the mistake of stating that soon each of us will know whether there is a hereafter. No, we won't. Not if there isn't one. As I strongly suspect. See here.
There seems to be a strange inability to accept the point here. Someone said, "It depends what you mean by 'know.'" I mean "know." Someone else said that even the absence of consciousness will be a kind of evidence. No, it won't. You cannot be aware of any evidence if you are not conscious.
I would like to find the answer to this question before death but the only way forward is scientific study of the alleged evidence and no question is more fraught with entrenched positions making objectivity almost impossible.
