A clear prediction in an area undergoing vigorous study permits doctrines to be subject to disproof. The last posture a bureaucratic religion wishes to find itself in is vulnerability to disproof, where an experiment can be performed on which the religion stands or falls. (Chapter 23, “A Sunday Sermon”) Critically, Plato and Aristotle, who were the best philosopher minds of the typical world in between, were deeply swayed by Pythagoras’ concepts. Sagan’s abilities lie in turning the hard relatable. In large part, nothing can be more huge than Cosmos. Knowing about the world isn’t usually about complicated math. It’s more like a history course like a science course. Pursuing Sagan’s clue, these book chapters lead you to a trip through humankind’s concern in space and the earth from ancient eras coming to the ultimate journeys of universe discovery during the 20th hundredth year. If we long for our planet to be important, there is something we can do about it. We make our world significant by the courage of our questions and by the depth of our answers.

Chapter 4 – There could be being on other planets; however, it’s not likely to get to our world with a spacecraft. a b Lewenstein, Bruce (March 2007). "Why should we care about science books?".

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.a b "Science and Technology: Public Attitudes and Understanding".

Indeed, the standard evolutionary practice of increasing the amount of genetic information as organisms increase in complexity is accomplished by doubling part of the genetic material and then allowing the slow specialization of function of the redundant set. ( Chapter 7, “Lovers and Madmen”) Much of human history can, I think, be described as a gradual and sometimes painful liberation from provincialism, the emerging awareness that there is more to the world than was generally believed by our ancestors. (Chapter 16, “The Golden Age of Planetary Exploration”)

While ritual, emotion and reasoning are all significant aspects of human nature, the most nearly unique human characteristic is the ability to associate abstractly and to reason. Curiosity and the urge to solve problems are the emotional hallmarks of our species; and the most characteristically human activities are mathematics, science, technology, music and the arts–a somewhat broader range of subjects than is usually included under the “humanities.” Indeed, in its common usage this very word seems to reflect a peculiar narrowness of vision about what is human. Mathematics is as much a “humanity” as poetry. ( Chapter 3, “The Brain and the Chariot”)Clarinet Concerto in A Major, K. 622" – Wolfgang Amadeus Mozart (Performed by Mostly Mozart Orchestra) (7:53) Humans are good, she knew, at discerning subtle patterns that are really there, but equally so at imagining them when they are altogether absent.
