Yes, I plan to read them.
Funnily enough, Lewis was a materialist before his conversion. It is interesting how he went from believing in nothing spiritual into believing that much was spiritual. On an off side, Tolkien considered chopping down trees to be “murder”. They were an interesting lot, these 20th century British Christians. They apparently talked about all sorts of subjects. One of the Inklings, Hugo Dyson, did not get along with Tolkien and when Tolkien got up to read a bit of The Lord of the Rings, he said “Oh God! Not more about the *Anglo Saxon expletive* elves!” Not a staid bunch of Christians, at all.
