The Gods Laughed

I am switching from Space Folk to The Gods Laughed (New York, 1982) because I think that the latter includes a story that is the obverse of "Backwardness," in other words a story about first contact with an alien race that is more intelligent than humanity - but I will find out. If the story that I am thinking of is not in this collection, then it must be in another.

Meanwhile, The Gods Laughed collects nine stories on the theme of human-alien contact, including:

"Peek! I See You!" and "Details," both discussed recently because reread in other collections;

"A Little Knowledge," part of Anderson's Technic Civilization History;

"Captive of the Centaurianess," which I think connects with "A Bicycle Built for Brew";

"Soldier From the Stars" - I remember the theme of this story, how to conquer Earth without destroying any of it, but I will reread it to appreciate the details;

"The Word to Space," in which a Jesuit descended from Moriarty confuses some aliens by questioning their religious dogmatism.

That leaves three stories:

"The Martyr"
"Nightpiece"
"When Half Gods Go"

- and, having glanced through the book, I am no longer sure that any of them is the one I thought, but they will be worth reading in any case.
