" "Por regla general, las sociedades humanas no son innovadoras, sino más bien jerárquicas y ritualistas. Cualquier sugerencia de cambio se acoge con recelo, ya que implica la incómoda transformación futura del ritual y la jerarquía imperantes, es decir, la sustitución de una serie de rituales por otra o, tal vez, por una sociedad menos estructurada y regida por un número inferior de rituales. Sin embargo, llega un momento en que es preciso que las sociedades cambien. «Los dogmas de un pasado tranquilo son insuficientes para un presente tumultuoso», aseveró Abraham Lincoln.

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
Mengenai manusia, kita adalah pendatang baru. Kita muncul pada detik-detik terakhir waktu kosmik. Sejarah Alam Semesta hingga sekarang telah 99,998 persen selesai sebelum spesies kita muncul. Dalam rentang waktu yang mahaluas itu, kita tidak mungkin memiliki tanggung jawab khusus apa pun untuk planet kita, kehidupan, atau apa pun itu. Kita belum ada di sini.
