THE DRAGONS OF EDEN 33 Weeks on The New York Times Bestseller List Carl Sagan is a very special scientist! He’s that teacher you always wish you had—and his book, The Dragons of Eden, is a masterpiece of instructive entertainment! “Carl Sagan has the Midas touch. Any subject he deals with turns to gold, and so it is in The Dragons of Eden. Never have I read anything on the subject of human intelligence as fascinating and as charming.” ISAAC ASIMOV “Provocative … Entertaining … Impressive … Even those of us who are not heavyweight thinkers will wish to pillow our craniums a bit more carefully at night after reading Sagan. He makes you realize that the gray mass between your ears is quite a treasure.” Chicago Daily News “Not all great thinkers are scientists, and not all scientists are great thinkers, but Sagan—young, zealous and imaginative—is both … THE DRAGONS OF EDEN…is really quite super.” Philadelphia Inquirer “Daring speculations and great fun … He argues for the worth and dignity of other species, even unknown species. If the alien creatures should ever touch down here, Sagan is one of those who would get a call in the middle of the night.” The Baltimore Sun “Extraordinary! … Exciting! … Sagan’s perspective ranges from the emergence of life on earth four billion years ago to the limitless possibilities for expanding human intelligence … A masterpiece of scientific writing for non-scientists.” Chicago Tribune “Absorbing … fascinating … The man writes clearly and well and often with humor … explaining, probing and relating with grace the story of the human brain.” Associated Press “Marvelous! … There are rewards of many sorts in this provocative book!” The Wall Street Journal “A joy! … A Carl Sagan is … a gifted and charismatic figure … he has become the idol of a whole generation of students.” The Washington Post Book World “In some lost Eden where dragons ruled, the foundations of our intelligence and passions were laid … Carl Sagan takes us on a guided tour of that lost land … Fascinating … Entertaining … Masterful!” St. Louis Post-Dispatch By Carl Sagan Published by Ballantine Books: BROCA’S BRAIN COSMOS THE DRAGONS OF EDEN MURMURS OF EARTH SHADOWS OF FORGOTTEN ANCESTORS (with Ann Druyan) COMET (with Ann Druyan) PALE BLUE DOT THE DEMON-HAUNTED WORLD BILLIONS AND BILLIONS A Ballantine Book Published by The Random House Publishing Group Copyright © 1977 by Carl Sagan All rights reserved.
