Are we on the brink of a new Dark Age of irrationality and superstition? In this book, the writer shows how scientific thinking is necessary to safeguard our democratic institutions and our technical civilization. This book is more personal and richer in moving and revealing human stories than anything the author has previously written. With illustrations from his own childhood experience as well as engrossing tales of discovery, he shows how the method of scientific thought can cut through prejudice and hysteria to uncover the often surprising truth. He convincingly debunks "alien abduction," "channelers," faith-healer fraud, the "face" on Mars, and much else. Along the way, he refutes the arguments that science destroys spirituality or is just another arbitrary belief system, asks why scientific study is often stigmatized, discusses the dangers of the misuse of science, and provides a "baloney detection kit" for thinking through political, social, religious, and other issues. -- Jacket

WHAT ARE THESE GRACEFUL VISITORS TO OUR SKIES? WE NOW KNOW THAT THEY BRING BOTH LIFE AND DEATH AND TEACH US ABOUT OUR ORIGINS. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. "SIMPLY THE BEST." *The Times of London "FASCINATING, EVOCATIVE, INSPIRING." *The Washington Post "COMET HUMANIZES SCIENCE. A BEAUTIFUL, INTERESTING BOOK." *United Press International "MASTERFUL . . . SCIENCE, POETRY, AND IMAGINATION." *The Atlanta Journal & Constitution
