First, thanks for the reference to this website. It looks like a great source of more deep thoughts.
Second, I’m not totally sure I understand him on this subject. However, I deal with impaired consciousness daily as a family medicine physician–from babies, to delirium impaired by drugs or toxins, to dementia. I am confident that consciousness, whatever God thinks the soul is, is not an integral, constant unit. We make memories, awareness, guilt, responsibility, all by a composite of material things.
I know that Lewis had his star, Ramandu (in The Voyage of the Dawn Treader) tell Eustace that being is not what we are, but what we are made of (my adaptation), but that has to do with responsibility and meaning.
I’m afraid that this is at risk for God of the gaps inference. I like the website, though! Thanks!
As I said, I am not sure I understand fully his point–so feel free to correct me.
