It's a book of education and culture, a book of science and history, a starting point for people to educate themselves. Centuries later, re-discovery of the writings of the free-thinking Greek philosophers helps inspire participants in the Scientific Revolution, which led to the development of the Copernican principle – the philosophical implications of which Sagan explores. The simple act of making an apple pie is extrapolated into the atoms and subatomic particles ( electrons, protons, and neutrons) necessary. In 2013, a new edition of Cosmos was published, with a foreword by Ann Druyan and an essay by Neil deGrasse Tyson.

Barcelona, Madrid, Bogotá, Buenos Aires, Caracas, México, Santiago de Chile, Editorial Planeta, 1985. The American astrophysicist Neil deGrasse Tyson described " Cosmos" as something "more than Carl Sagan". Featuring a new Introduction by Sagan's collaborator, Ann Druyan, and a new Foreword by astrophysicist Neil deGrasse Tyson, Cosmos retraces the fourteen billion years of cosmic evolution that have transformed matter into consciousness, exploring such topics as the origin of life, the human brain, Egyptian hieroglyphics, spacecraft missions, the death of the Sun, the evolution of galaxies, and the forces and individuals who helped to shape modern science. Along with Microbe Hunters and The Double Helix, he described Cosmos as one of the "books that people cite as 'Hey, the reason I'm a scientist is because I read that book'. So, if you are wanting in depth analysis on Pulsars, Black Holes, our Solar System etc then this is not a work that focuses greatly on those elements.All used books might have various degrees of writing, highliting and wear and tear and possibly be an ex-library with the usual stickers and stamps. For people just getting introduced to astronomy it is still close enough to present views of the universe to give a good introduction and understanding. The journeys of the Voyager probes are put in the context of the Netherlands in the seventeenth century, with a centuries-long tradition of sailing ship explorers, and its contemporary thinkers (such as Constantijn Huygens and his son Christian). In 1994, RCA Records reissued the original soundtrack compilation on compact disc and, in 2002, reissued it on its Collectables label (RCA 07863 54003-2 USA; Collectables COL-CD-6293 USA).

As for the content he reads, lets just say I am saddened that Carl Sagan died before I ever knew who he was.The program's format is similar to earlier BBC documentaries such as Kenneth Clark's Civilisation, Jacob Bronowski's The Ascent of Man, and David Attenborough's Life on Earth. The lucidity with which Carl delivers his insights about the Cosmos and our relationship to the Universe is eye opening and awe inspiring.
