This story is terrible in every way except for writing style. Implausible concept, characters colorless, too numerous, confusing beginning, too long. The idea behind it is neat, but meatless, and it just doesn't work.
I expected much more of supposedly one of the greatest sci-fi stories ever by the famous Asimov. (included in the Science Fiction Hall of Fame Vol. 1, voted in by sci-fi writers)
spoilery discussion of the story concept:
so on a permanently lit planet with 6 stars, there's a total eclipse every 2050 years, when people go insane because they're afraid of the dark and they suddenly realize that there are all those stars in the sky, so they burn all houses to have some light and all culture resets in this endless cycle.
Really?
They have electricity and torches, so they should have more than enough means to prevent going crazy from darkness.
They know exactly what is going to happen, so they should be able to prepare for this darkness.
Some of the people should have the hint of reason not to go insane from an eclipse, preserving knowledge.
Passing on knowledge should be an easy task anyways, unavoidable even. The idea is probably that all libraries would be burned, but there should be enough left to reconstruct the most important concepts.
Even if this concept worked, and i see the beauty and terror of all mankind experiencing night and a sky of stars for the first time, that wouldn't make too much of a story, and the events and characters built around the idea have no meat either.
There are some astronomers idling around without any motivation playing chess, because hey, it's just the end of the world, and some people discussing whether to publish a newspaper story about this. Okay, the idea of a cult integrating knowledge about the cycle into a holy text is neat, but that's about it. There are too many characters in the story that one can't place and that don't capture your interest.
