" "The impediment to scientific thinking is not, I think, the difficulty of the subject. Complex intellectual feats have been mainstays even of oppressed cultures. Shamans, magicians and theologians are highly skilled in their intricate and arcane arts. No, the impediment is political and hierarchical.
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.

Numa vida curta e incerta, parece cruel fazer qualquer coisa que possa privar as pessoas do consolo da fé, quando a ciência não pode remediar a sua angústia. Aqueles que não conseguem suportar o peso da ciência têm a liberdade de ignorar os seus preceitos. Mas não podemos fazer ciência aos pedacinhos, aplicando-a quando nos sentimentos seguros e ignorando-a quando nos sentimos ameaçados - mais uma vez, porque não temos sabedoria para tanto. A não ser dividindo a mente em compartimentos herméticos separados, como é possível voar em aeroplanos, escutar rádio ou tomar antibióticos, sustentando ao mesmo tempo que a Terra tem cerca de 10 mil anos ou que todos os sagitarianos são gregários e afáveis?

The cerebral cortex is a liberation. We need no longer be trapped in the genetically inherited behavior patterns of lizards and baboons. We are, each of us, largely responsible for what gets put into our brains, for what, as adults, we wind up caring for and knowing about. No longer at the mercy of the reptile brain, we can change ourselves.
