Well, honey, in 'The Chrysalids', Jacob's got three axioms hanging in his home like decorations at a Christmas party. One says "The Devil is the father of deviation", another one goes "Watch Thou for the Mutant!", and the last one is "Purity is the best policy". So, there you have it, straight from the horse's mouth.
