" "Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.

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
But the history of science — by far the most successful claim to knowledge accessible to humans — teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error bars a little, and to add to the body of data to which error bars apply. The error bar is a pervasive, visible self-assessment of the reliability of our knowledge.
Qlobal qızğın silahlanmanı dünyadan kənar və qərəzsiz müşahidəçiyə necə izah edə bilərdik? Ən son sabitliyi pozan tədqiqatlara- qatil peyklərə, dəstə silahlara, lazerlərə, neytron bombalara, qanadlı raketlərə, - və orta ölçüsü olan ölkə ilə müqayisə edilən ərazilərin yüzlərlə maketlərin arasında əsl qitələrarası ballistik raketlərin gizləndiyi təklif olunmuş poliqon transformasiyasına necə bəraət qazandırardıq? Hədəf almış on minlərlə döyüş başlıqlarının sağ qalma ehtimalımızı artırdığını cəsarət ilə iddia edə bilərdikmi? Yer kürəsinin kuratoruna hansı hesabatı verə bilərdik? Biz nüvə dövlətlərinin dəlillərini bilirik. Millətlərin adından kimin danışdığı bizə məlumdur. Bəs insan növünün adından kim danışır? Kim Yer kürəsinin adından danışır?

"I'm frequently asked, "Do you believe there's extraterrestrial intelligence?" I give the standard arguments- there are a lot of places out there, the molecules of life are everywhere, I use the word billions, and so on. Then I say it would be astonishing to me if there weren't extraterrestrial intelligence, but of course there is as yet no compelling evidence for it.
Often, I'm asked next, "What do you really think?"
I say, "I just told you what I really think."
"Yes, but what's your gut feeling?"
But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble. Really, it's okay to reserve judgment until the evidence is in."
