What makes The Chrysalids have enduring value?
The enduring value of John Wyndham's novel The Chrysalids lies in it's captivating story, Wyndham's writing style (you should try The Day of the Triffids too!), and the ever relevant theme of blind obedience and it's resultant prejudice. First, in the story set thousands of years in the future, with people who are still very much like people of today, some children are born who have pronounced telepathic abilities (they communicate with each other by thought transmission) in a society called Waknuk in Labrador, Canada, where everything must be pure and all mutations are destroyed, if plant or animal, or exiled, if lucky and human.
Second, Wyndham's writing style is casual yet engrossing. He tells the tales simply yet with a sincerity and an energy that makes the story believable, though Science Fiction, keeps the pages turning. Third, Wyndham's theme is timeless, that of blindly following old prescriptions for behavior or what one is told and the prejudices that inevitably develop against those who go astray accidentally or intentionally from the prescribed beliefs and behaviors (the unexamined life condemned by Socrates).
