But he does not cite cases that are still a mystery. Carl Sagan gives many explanations for the debunking of various UFO sightings, and tales of abduction. I'm a bit disappointed that the Illuminati was never mentioned even once. A sizable chunk of the book deals with UFOs and conspiracy theories. Both the near present and distant past were examined for examples of presence or any degree of absence of knowledge. This book contains many examples of pain that could have been avoided, although that's not what one thinks when confronted with the Inquisition practices and confronted with the fate of the victims, all of whom are 100% sure to be innocent, without any trace of doubt.

As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms. And yet, disturbingly, in today's so-called information age, pseudoscience is burgeoning with stories of alien abduction, channeling past lives, and communal hallucinations commanding growing attention and respect. How can we make intelligent decisions about our increasingly technology-driven lives if we don't understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.Casting a wide net through history and culture, Sagan examines and authoritatively debunks such celebrated fallacies of the past as witchcraft, faith healing, demons, and UFOs.
