121 " For ages men had used sticks to club and spear each other—Anaximander of Miletus used the stick to measure time. "
― Carl Sagan , Cosmos
122 " Adolf Hitler! Ken, it makes me furious. Forty million people die to defeat that megalomaniac, and he's the star of the first broadcast to another civilization? He's representing us. And them. It's that madman's dream come true. "
― Carl Sagan , Contact
123 " If it takes a little myth and ritual to get us through a night that seems endless, who among us cannot sympathize and understand? "
― Carl Sagan
124 " I know of no significant advance in science that did not require major inputs from both cerebral hemispheres. This is not true for art, where apparently there are no experiments by which capable, dedicated and unbiased observers can determine to their mutual satisfaction which works are great. "

125 " There are many hypotheses in physics of almost comparable brilliance and elegance that have beenrejected because they did not survive such a confrontation with experiment. In my view, the human condition would be greatly improved if such confrontations and willingness to reject hypotheses were a regular part of our social, political, economic, religious and cultural lives. "
126 " Would not a rational society spend more on understanding and preventing, than on preparing for, the next war? "
127 " The school systems, it seems to me have a attitude of discouragement of asking fundamental questions, if a 5 or 6 year old asks why the moon is round or why the grass is green? The usual adult answer, at least in my experience is to discourage the child.what color did you expect the moon to be? square? what color you expect the grass to be?blue?Instead of saying that those are interesting questions and lets try to find the answers or maybe nobody knows the answers and when you grow up you would be able to discover the answers.It would be very healthy for human species if we could have less discouragement and more scientists.– Carl Sagan(In an interview with Magnus Magnusson, 1988) "
128 " What do you do when you are faced with several different gods each claiming the same territory? The Babylonian Marduk and the Greek Zeus was each considered master of the sky and king of gods. You might also decide, since they had quite different attributes, that one of them was merely invented by the priests. But if one, why not both? And so it was that the great idea arose, the realization that there might be a way to know the world without the god hypothesis; that there might be principles, forces, laws of nature, through which the world could be understood without attributing the fall of every sparrow to the direct intervention of Zeus. "
129 " All of us cherish our beliefs. They are, to a degree, self-defining. When someone comes along who challenges our belief system as insufficiently well based - or who, like Socrates, merely asks embarrassing questions that we haven't thought of, or demonstrates that we've swept key underlying assumptions under the rug - it becomes much more than a search for knowledge. It feels like a personal assault. "

130 " Liberation from superstition is a necessary but not a sufficient condition for science. "
131 " Often, superstition and injustice are imposed by the same ecclesiastical and secular authorities, working hand in glove. It is no surprise that political revolutions, scepticism about religion, and the rise of science might go together, "
132 " But we have no [Marian] apparitions cautioning the Church against, say, accepting the delusion of an Earth-centered Universe, or warning it of complicity with Nazi Germany — two matters of considerable moral as well as historical import....Not a single saint criticized the practice of torturing and burning “witches” and heretics. Why not? Were they unaware of what was going on? Could they not grasp its evil? And why is [the Virgin] Mary always admonishing the poor peasant to inform the authorities? Why doesn’t she admonish the authorities herself? Or the King? Or the Pope? "
133 " All science asks is to employ the same levels of skepticism we use in buying a used car or in judging the quality of analgesics or beer from their television commercials. "
134 " And yet, the chief deficiency I see in the sceptical movement is in its polarization: Us v. Them - the sense that we have a monopoly on the truth; that those other people who believe in all these stupid doctrines are morons; that if you're sensible, you'll listen to us; an if not, you're beyond redemption. This is unconstructive. It does not get the message across. It condemns the sceptics to permanent minority status; whereas, a compassionate approach that from the beginning acknowledges the human roots of pseudoscience and superstition might be much more widely accepted. "
135 " One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time. "
136 " Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil. "
137 " One glance at (a book) and you hear the voice of another person - perhaps someone dead for thousands of years. Across the millenia, the author is speaking, clearly and silently, inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people, citizens of distant epochs, who never knew one another. Books break the shackles of time. "
138 " We make our purpose. "

139 " Can you be sure that others have not come before you and destroyed the pristine state of the native myth? Can you be sure that the natives are not humoring you or pulling your leg? Bronislaw Malinowski thought he had discovered a people in the Trobriant Islands who had not worked out the connection between sexual intercourse and childbirth. When asked how children were conceived, they supplied him with an elaborate mythic structure prominently featuring celestial intervention. Amazed, Malinowski objected that was not how it was done at all, and supplied them instead with the version so popular in the West today – including a nine-month gestation period. “Impossible,” replied the Melanesians. “Do you not see that woman over there with her six-month-old child? Her husband has been on an extended voyage to another island for two years.” Is it more likely that the Melanesians were ignorant of the begetting of children or that they were gently chiding Malinowski? If some peculiar-looking stranger came into my town and asked ME where babies came from, I’d certainly be tempted to tell him about storks and cabbages. Prescientific people are people. Individually they are as clever as we are. "

140 " The symbolism seemed so apt. The same technology that can propel apocalyptic weapons from continent to continent would enable the first human voyage to another planet. It was a choice of fitting mythic power: to embrace the planet named after, rather than the madness ascribed to, the god of war. "
