" "Science cuts two ways, of course; its products can be used for both good and evil. But there's no turning back from science. The early warnings about technological dangers also come from science.
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.

Тези, които търсят власт на всяка цена, забелязват обществената слабост — някакъв страх, който могат да яхнат, и така да стигнат до високите постове. Това може да са етнически различия — както е в този случай — или може би различно количество меланин в кожата; някоя различна философия или религия; а защо не употребата на наркотици, проявите на насилие, икономическата криза, молитвата в училище или поругаването (английският глагол desecrate означава буквално „правя несвещен“) на националното знаме.
Какъвто и да е проблемът, бързото решение е да се премахнат част от свободите в Декларацията за правата на гражданите. Да, през 1942 г. американците от японски произход бяха защитени от Декларацията за правата, но ние все пак ги затворихме — в крайна сметка се водеше война. Да, има конституционни забрани срещу безпричинните обиски и арести, но водим война срещу наркотиците, а престъпността излиза от контрол. Да, има свобода на словото, но нали не искаме тук да се мотаят чужди автори и да проповядват чужди идеологии? Претекстът се променя всяка година, но резултатът е същият: концентриране на повече власт в по-малко ръце и потискане на различните мнения — дори и когато опитът ясно показва рисковете от подобни действия.
"Even if we ourselves are not personally scandalized by the notion of other animals as close relatives, even if our age has accommodated to the idea, the passionate resistance of so many of us, in so many epochs and cultures, and by so many distinguished scholars, must say something important about us. What can we learn about ourselves from an apparent error so widespread, propagated by so many leading philosophers and scientists, both ancient and modern, with such assurance and self-satisfaction?
One of several possible answers: A sharp distinction between humans and "animals" is essential if we are to bend them to our will, make them work for us, wear them, eat them — without any disquieting tinges of guilt or regret. With untroubled consciences, we can render whole species extinct — for our perceived short-term benefit, or even through simple carelessness. Their loss is of little import: Those beings, we tell ourselves, are not like us. An unbridgeable gap gas thus a practical role to play beyond the mere stroking of human egos. Darwin's formulation of this answer was: "Animals whom we have made our slaves, we do not like to consider our equals.
