" "Всяка среща с Халеевата комета е била повод за изразяване на надежди и страхове. Същото се отнася и до появата на ярки непериодични комети. Почти ритуално това е било време да се помолим. Ето защо за следващата поява на Халеевата комета и на кометата Хейл-Боп ние предлагаме една своя молитва: Живеем на крехка планета, от чийто грижливо опазване зависи дали ще има бъдеще за нашите деца. Ние сме само временните попечители на един свят, който сам по себе си не е нищо повече от една прашинка в невъобразимо необятна и стара Вселена. Затова нека се научим да постъпваме преди всичко в интерес на вида и планетата ни.
Тогава още неизброимо много нощи ще има хора, които да бъдат свидетели на величието на кометите, благословили земното небе.
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.

The ancient Aztec and the ancient Greek words for “God” are nearly the same. Is this evidence of some contact or commonality between the two civilizations, or should we expect occasional such coincidences between two wholly unrelated languages merely by chance? Or could, as Plato thought in the Cratylus, certain words be built into us from birth?
What distinguishes our species is thought. The cerebral cortex is in a way a liberation. We need no longer be trapped in the genetically inherited behavior patterns of lizards and baboons: territoriality and aggression and dominance hierarchies. We are each of us largely responsible for what gets put in to 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. Think of the possibilities.
