It is the sequel to Cosmos and was inspired by the famous Pale Blue Dot photograph, for which Sagan provides a poignant description. In the book, Sagan mixes philosophy about the human place in the universe with a description of the current knowledge about the Solar System. He also details a human vision for the future. The first part of the book examines the claims made throughout history that Earth and the human species are unique. Sagan proposes two reasons for the persistence of the idea of a geocentric , or Earth-centered universe: human pride in our existence, and the threat of torturing those who dissented from it, particularly during the time of the Roman Inquisition.

A Pale Blue Dot

As the spacecraft was departing our planetary neighborhood for the fringes of the solar system, it turned it around for one last look at its home planet.

Voyager 1 was about 6. Caught in the center of scattered light rays a result of taking the picture so close to the Sun , Earth appears as a tiny point of light, a crescent only 0. Look again at that dot. That's here. That's home.

That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light.

Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience.

There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

The book is written by Carl Sagan and is a vision of what will happen to us in space. The first four chapters of Saganic theology deal with the idea that humans are self-centered and think their conflicts are important. It seems to be a common theme in Western religions that man is fallen, although the stars hold promise for human unity and redemption. When we look at Earth from a distance, it looks like a pale blue dot. This perspective Sagan believes should make us realize how insignificant and small we are in the grand scheme of things.

humans into space. In the last and most speculative part of the book, I trace how I imagine that our long-term future in space will work itself out. Pale Blue Dot is.
