This demonstrates a pitfall the preferred length of modern SF generally skirts. I began intended just to reread Edgar Pangborn’s post-holocaust Bildungsroman Davy but because I was also planning to reread Canticle for Leibowitz, which covers centuries to Davy’s decades I then began to ponder if it would be better to reread all the stories Pangborn wrote in that setting so I would be comparing similar spans of time or at least half a millennium to 1800 years. After all, both The Company of Glory and The Judgment of Eve are short and the collection Still I Persist in Wondering is under 300 pages. Of course, it all added up to something as long as The Past Through Tomorrow or Adventures in Time and Space. I am sure there is a lesson here somewhere and equally sure that I didn’t learn it.
Although he is comparatively obscure now, in the 1950s Pangborn won an International Fantasy Award for his A Mirror for Observers, a Hugo nomination for Davy (which lost to Leiber’s execrable The Wanderer ; what the hell, SF fandom?), and Nebula nominations for “A Better Mousehole” and “Mount Charity”. A fair fraction of his work was set the Darkening World, in a world where thanks to resource depletion, overpopulation, light nuclear war, and a host of almost certainly engineered plagues, civilization collapsed, leaving in its wake a small and infertile population of people to survive as best they can.
