Los libros lo cambiaron todo. Los libros, que se pueden comprar a bajo coste, nos permiten preguntarnos por el pasado con gran precisión, aprovechar la sabiduría de nuestra especie, entender el punto de vista de otros, y no solo de los que están en el poder; contemplar -con los mejores maestros- los conocimientos dolorosamente extraídos de la naturaleza por las mentes más grandes que jamás existieron, en todo el planeta y a lo largo de toda nuestra historia. Permiten que gente que murió hace tiempo hable dentro de nuestras cabezas. Los libros nos pueden acompañar a todas partes. Los libros son pacientes cuando nos cuesta entenderlos, nos permiten repasar las partes difíciles tantas veces como queramos y nunca critican nuestros errores. Los libros son la clave para entender el mundo y participar en una sociedad democrática.

About Carl Sagan

Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan

All of us cherish our beliefs. They are, to a degree, self-defining. When someone comes along who challenges our belief system as insufficiently well-based – or who, like Socrates, merely asks embarrassing questions that we haven’t thought of, or demonstrates that we’ve swept key underlying assumptions under the rug – it becomes much more than a search for knowledge. It feels like a personal assault.
