The major religions on the Earth contradict each other left and right. You can't all be correct. And what if all of you are wrong? It's a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I'm not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they're called hypotheses, not inspiration and not revelation.

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

Ценностите на науката и ценностите на демокрацията са много сходни, а в редица случаи са неразличими. Науката и демокрацията са се появили — в цивилизованите си превъплъщения — по едно и също време на едно и също място, в Гърция през VII и VI в. пр.Хр. Науката дава власт на всеки, който си даде труд да я изучи (макар че мнозина систематично са лишавани от тази възможност). Науката се подхранва от и дори изисква свободен обмен на идеи. Нейните ценности са противоположното на потайността. Науката не поддържа специални предимства или привилегировани позиции. Както науката, така и демокрацията поощряват неконвенционалните мнения и разпалените дискусии. И двете изискват адекватни причини, смислени доводи и строги стандарти на доказателственост и почтеност. Науката предоставя начини да бъде изобличен блъфът на тези, които само се преструват, че знаят. Тя е крепост срещу мистицизма и суеверието, срещу прилагането на религията в области, където няма място за нея. Ако останем верни на нейните ценности, тя ще ни покаже кога ни лъжат. Науката ни помага да поправим грешките си, преди да е станало късно. Колкото по-голямо разпространение получат нейният език, правила и методи, толкова по-голям шанс имаме да запазим това, което са имали предвид Томас Джеферсън и неговите колеги. Но творенията на науката позволяват на демокрацията да бъде покварена много по-лесно, отколкото си е мечтал който и да било прединдустриален демагог.

Science thrives on errors, cutting them away one by one. False conclusions are drawn all the time, but they are drawn tentatively. Hypotheses are framed so they are capable of being disproved. A succession of alternative hypotheses is confronted by experiment and observation. Science gropes and staggers toward improved understanding. Proprietary feelings are of course offended when a scientific hypothesis is disproved, but such disproofs are recognized as central to the scientific enterprise. Pseudoscience is just the opposite. Hypotheses are often framed precisely so they are invulnerable to any experiment that offers a prospect of disproof, so even in principle they cannot be invalidated. Practitioners are defensive and wary. Skeptical scrutiny is opposed. When the pseudoscientific hypothesis fails to catch fire with scientists, conspiracies to suppress it are deduced.
