Pale Blue Dot: a Vision of the Human Future in Space

Pale Blue Dot is a journey in time and space. Beginning with the assertion that we're natural wanderers, being the only species to settle across our world, it continues with a plea to extend further our exploration of space. The early chapters challenge restrictions on our desire to explore and learn. Sagan demonstrates how foolish minds have restrained our quest for knowledge of the cosmos. He then takes us on a tour of the solar system, exhibiting the wonders revealed by the fleet of robot probes. He reminds us of the forces the cosmos can unleash, sometimes right in our neighbourhood. Like many of the rest of us, Sagan was awed by the collision of a comet with the Jovian gas giant. It was a hint of what might lay in store for us if we fail to understand the universe better than we do now. The space probes also returned images of worlds invalidating existing theories of planetary formation. If our own neighbours can present such bizarre structures, what kinds of worlds ride beyond our ken, circling suns we can barely imagine? What Sagan can't portray, he can conjecture. With his firm working scientist's foundation, Sagan's speculations command respectful attention.

This book must be shelved alongside Richard Dawkins THE SELFISH GENE and THE BLIND WATCHMAKER. Together, these three fine works confront the traditional Western view of a universe and the life in it resulting from a Designer. From Dawkins' biological analysis to Sagan's cosmological view, this obstructionist outlook is here rendered groundless. More people must read Pale Blue Dot to gain an idea of who we are and where we stand in the vastness of a nearly limitless universe. Please read this book and convey its ideas to others. There is much to be gained from its imparted wisdom. [stephen a. haines - Ottawa, Canada]

Carl Sagan is one of the most brilliant thinkers of our generation and this book is an exclamation mark on a fruitful and alas, too short, career. This book is a sequel to the well-known "cosmos" in which, the author contemplates on the future of humankind on earth and in the farthest regions of space. As always, it is a riveting journey guided by the enthusiastic, humorous and eloquent Sagan who manages to leave the reader with a feeling of cautious optimism despite the many reasons humankind has to worry about its future. An excellent read.
