The Demon-Haunted World: Science as a Candle in the Dark (CHAPTERED & ORGANIZED) 

A fight against pseudo-science is held by many scientists of the 20th century. In this book, Carl Sagan provides a skeptical analysis of several kinds of superstition, fraud, pseudoscience and religious beliefs, such as gods, witches, UFOs and faith healing. However, based on "some experimental support," Sagan calls for serious scrutiny of a handful of seemingly inexplicable phenomena such as reincarnation and psychokinesis, not because he regards them as likely to be true, but because anomalous data deserves close scientific study.
