Bethany: Psychologists have discovered a technique for replacing one's nightmares with pleasant dreams, and have successfully taught it to adults suffering from chronic nightmares. ███████ ████ █████ ████ ███████████████ ████████ ███ ██████████ ██████ ██ ██████ ████ ██████████ ██ ███████ █████ █████████████ ██████ ██████ ███████ ██████ ███████████ ███████████████ ████████ ██ ████ █████ ████████ ███ ██ ██████ ███ █████████ ███ █████████ █████ ██████████ ████ ████████ ███████
Bethany concludes that psychologists should try to identify nightmare-prone children and teach them the effective new technique. Why? Because nightmare-prone children are likely to be nightmare-prone adults.
Bethany concludes that psychologists should teach the technique to nightmare-prone children, but her premises never establish when psychologists should do something. She’s assuming that they should try to help children with their nightmares. Since nightmare-prone children are likely to become nightmare-prone adults, she may also assume that psychologists should help prevent people from becoming nightmare-prone adults.
We need a rule or principle that helps justify her conclusion by confirming that psychologists should indeed try to identify nightmare-prone children and teach them the technique.
