The Demon-Haunted World
The Demon-Haunted World asks how people can distinguish reliable knowledge from comforting stories in a technologically powerful society. Sagan joins wonder to skepticism, then traces the question through UFOs, memory, education, media, scientific responsibility, and democratic freedom. The practical value is a disciplined way to test claims without losing humane curiosity.
