To me, the greatest Christian philosopher and theologian of the 20th C, Lewis did it again with this narrative treatise on the afterlife. Probably inspired by Dante and McDonald. This is a bit of a talkfest, but it’s nonetheless gripping and it’s a short read.
The two things I loved best were:
1) Lewis’ mid-20th Century willingness to push against orthodoxy and rethink heaven and hell and purgatory with a fresh mind
2) the sheer pathos of the human condition and its willingness to turn from truth and opportunity out of sheer spite and self-importance.
