Publisher Description

"A glorious book . . . A spirited defense of science . . . From the first page to the last, this book is a manifesto for clear thought."

*Los Angeles Times

*The Washington Post Book World

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. 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. 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.


*USA Today

"A clear vision of what good science means and why it makes a difference. . . . A testimonial to the power of science and a warning of the dangers of unrestrained credulity."

A Light in Dark Times

This brilliant and exhaustively researched book is even more germane and useful today in Trump’s America than it was twenty years ago. Sagan’s hymn to the need for science and rationality as the basis of American progress and security should sound in all public discourse.

Stop Making Sense Mr. Sagan

An excellent read. Sagan was a great Science communicater. This is right up there with his work on Cosmos.
