«El mundo y sus demonios» is Carl Sagan's popular science essay, published by Círculo de Lectores in hardback (524 pages, in Spanish).
Carl Sagan defends critical thinking and the scientific method to distinguish science from pseudoscience. He presents the «kit del escéptico», with tools such as independent confirmation, quantification and Occam's razor, and applies it to superstitions, UFOs, extrasensory perceptions and miraculous healings.
Originally published as «The Demon-Haunted World» in 1995, it received the Los Angeles Times Book Prize for science and technology in 1996.
Aimed at the general reader who wants to start in critical thinking and science popularisation, with an accessible approach.

Carl Edward Sagan was an American astronomer, planetary scientist and science communicator. Initially an assistant professor at Harvard, Sagan later moved to Cornell, where he was the David Duncan Professor of Astronomy and Space Sciences and directed the Laboratory for Planetary Studies. He played an active role in the Mariner, Viking and Voyager programs. He published more than 600 scientific papers and articles and several popular science books, starting with The Cosmic Connection. He won the Pulitzer Prize for General Nonfiction for The Dragons of Eden.
