" "Whenever our ethnic or national prejudices are aroused, in times of scarcity, during challenges to national self-esteem or nerve, when we agonize about our diminished cosmic place and purpose, or when fanaticism is bubbling up around us — then, habits of thought familiar from ages past reach for the controls. The candle flame gutters. Its little pool of light trembles. Darkness gathers. The demons begin to stir.

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
A healthy young man can produce in a week or two enough spermatozoa to double the human population of the Earth. So is masturbation mass murder? How about nocturnal emissions or just plain sex? When the unfertilized egg is expelled each month, has someone died? Should we mourn all those spontaneous miscarriages?
Öyle garip kavramlarla yetiştirilmişiz ki, bizden birazcık değişik bir kişi ya da toplumla karşılaşınca, onların bize yabancılığı nedeniyle güvensizlik duyuyoruz ya da nefret ediyoruz. Oysa her bir uygarlığın anıtları ve kültürü, insan olmanın değişik biçimde anlatımından başka bir şey değildir. Yerküre-dışı bir ziyaretçi çeşitli insanlar ve insan toplumları arasındaki farklara göz attığında, aramızdaki benzerlikleri farklardan daha çok bulacaktır. Kozmos'u akıllı yaratıklar dolduruyor olabilir. Fakat Darwin'in öğretisi açıktır: Başka bir yerde insana rastlayamazsınız. Yalnızca gezegenimizde vardır insan. Bu küçücük gezegenimizde. Nadir ama tehlikeli bir türüz. Kozmik perspektifte, her birimiz çok değerliyiz. Eğer bir insanın sizinle aynı fikri paylaşmadığını fark ederseniz, aldırmayın, bırakınız bu gezegende yaşamaya devam etsin. Unutmayın, yüz milyar galaksiyi gezip tek bir insan bile bulamayabilirsiniz.
Look again at that dot. That’s here. That’s home. That’s us… The Earth is the only world known so far to harbor life…Like it or not, for the moment the Earth is where we make our stand… There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known. — CARL SAGAN, reflecting on a photograph of Earth taken by the Voyager 1 space probe from a distance of 6 billion kilometers (Pale Blue Dot, 1994)
