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
