“DOWNRIGHT INSPIRATIONAL.”—People
“Elegant and appealing … Jargon-free English buoyed by emotion and humor … Sagan’s optimistic vision … shines through every chapter.”
—Time
“A practical and poetic argument for expanded space travel and exploration … In typical Sagan fashion, [he] makes his case grandly and eloquently.”
—The San Diego Union-Tribune
“Enthralling … [Sagan was] a true believer in the wealth of the universe, and he may yet make apostles of us all.”
—Entertainment Weekly
“Glowingly communicates current wonders and large issues ahead … No recent book has done better at making plain the subtle nature and the fascination of scientific investigation.”
—Scientific American
“[Pale Blue Dot] has the ambiance of a salon, where Galileo, Einstein, and others hold forth.”
—Air & Space
“Passionate, eloquent … [Sagan] fires our imagination and turns science into high drama.”
—Booklist
“Eloquent, impassioned … He builds a cogent argument that our species must venture into this vast realm and establish a space-faring civilization.”
—Kirkus Reviews
