Carl Sagan

Cosmos is a 1980 popular science book by astronomer and Pulitzer Prize-winning author Carl Sagan. Its 13 illustrated chapters, corresponding to the 13 episodes of the Cosmos TV series, which the book was co-developed with and intended to complement, explore the mutual development of science and civilization. One of Sagan's main purposes for the book and television series was to explain complex scientific ideas to anyone interested in learning. Sagan also believed the television was one of the greatest teaching tools ever invented, so he wished to capitalize on his chance to educate the world. Spurred in part by the popularity of the TV series, Cosmos spent 50 weeks on the Publishers Weekly best-sellers list and 70 weeks on the New York Times Best Seller list to become the best-selling science book ever published at the time. In 1981, it received the Hugo Award for Best Non-Fiction Book. The book's unprecedented success ushered in a dramatic increase in visibility for science-themed literature. The success of the book also jumpstarted Sagan's literary career. The sequel to Cosmos is Pale Blue Dot: A Vision of the Human Future in Space .In 2013, Cosmos was published in a new edition, with a foreword by Ann Druyan and an essay by Neil deGrasse Tyson.

“The neurochemistry of the brain is astonishingly busy, the circuitry of a machine more wonderful than any devised by humans. But there is no evidence that its functioning is due to anything more than the 1014 neural connections that build an elegant architecture of consciousness.”

Quoting Vincent van Gogh, p. 217
Cosmos (1980)

“There is no other species on the Earth that does science. It is, so far, entirely a human invention, evolved by natural selection in the cerebral cortex for one simple reason: it works. It is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. We must understand the Cosmos as it is and not confuse how it is with how we wish it to be.”

“The Platonists and their Christian successors held the peculiar notion that the Earth was tainted and somehow nasty, while the heavens were perfect and divine. The fundamental idea that the Earth is a planet, that we are citizens of the Universe, was rejected and forgotten.”

“Our intelligence and our technology have given us the power to affect the climate. How will we use this power? Are we willing to tolerate ignorance and complacency in matters that affect the entire human family? Do we value short-term advantages above the welfare of the Earth? Or will we think on longer time scales, with concern for our children and our grandchildren, to understand and protect the complex life-support systems of our planet? The Earth is a tiny and fragile world. It needs to be cherished.”
