" "Mas há outra razão. A ciência é mais do que um corpo de conhecimento, é um modo de pensar. Tenho um pressentimento sobre a América do Norte dos tempos de meus filhos ou de meus netos - quando os Estados Unidos serão uma economia de serviços e informações; quando quase todas as principais indústrias manufatureiras terão fugido para outros países; quando tremendos poderes tecnológicos estarão nas mãos de uns poucos, e nenhum representante do interesse público poderá sequer compreender de que se trata; quando as pessoas terão perdido a capacidade de estabelecer seus próprios compromissos ou questionar compreensivelmente os das autoridades; quando, agarrando os cristais e consultando nervosamente os horóscopos, com as nossas faculdades críticas em decadência, incapazes de distinguir entre o que nos dá prazer e o que é verdade, voltaremos a escorregar, quase sem notar, para a superstição e a escuridão.
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.

As a boy Kepler had been captured by a vision of cosmic splendour, a harmony of the worlds which he sought so tirelessly all his life. Harmony in this world eluded him. His three laws of planetary motion represent, we now know, a real harmony of the worlds, but to Kepler they were only incidental to his quest for a cosmic system based on the Perfect Solids, a system which, it turns out, existed only in his mind. Yet from his work, we have found that scientific laws pervade all of nature, that the same rules apply on Earth as in the skies, that we can find a resonance, a harmony, between the way we think and the way the world works.
When he found that his long cherished beliefs did not agree with the most precise observations, he accepted the uncomfortable facts, he preferred the hard truth to his dearest illusions. That is the heart of science.
