Issued on the 25th anniversary of the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), this book brings together personal statements by the leading skeptics of the world. CSICOP, the first major organization of skeptics on the contemporary scene, is worldwide in scope and is dedicated to the skeptical evaluation of both paranormal and religious claims in the light of scientific inquiry. All of the articles are original and written especially for this collection. Many pieces are autobiographical; others reflect on the current state of research into paranormal claims.

The contributors focus on ESP and parapsychology, astrology, UFOlogy, the difference between science and pseudoscience, alternative medicine, magic, near-death experiences, spiritual energy, Bible codes, and religious claims that purport to have empirical foundations.

Among the thirty-seven distinguished contributors are Martin Gardner (former columnist for Scientific American), Leon Jaroff (former science editor of Time), Philip J. Klass (the leading UFO skeptic), Antony Flew (noted British philosopher), Kendrick Frazier (editor of the Skeptical Inquirer), the late Steve Allen (noted author, comedian, and television pioneer), Bill Nye ("The Science Guy"), Jean-Claude Pecker (one of France's leading astronomers), Joe Nickell (paranormal investigator), Susan J. Blackmore (parapsychologist), Eugenie Scott (critic of "creationism"), among others. Contributors come from the USA, Canada, Britain, France, India, the Netherlands, Spain, Mexico, and Russia.
