"Be aware of this truth that the people on this earth could be joyous, if only they would live rationally and if they would contribute mutually to each others' welfare.This world is not a vale of sorrows if you will recognize discriminatingly what is truly excellent in it; and if you will avail yourself of it for mutual happiness and well-being. Therefore, let us explain as often as possible, and particularly at the departure of life, that we base our faith on firm foundations, on Truth for putting into action our ideas which do not depend on fables and ideas which Science has long ago proven to be false."
"Not everyone understands what a completely rational process this is, this maintenance of a motorcycle. They think it's some kind of 'knack' or some kind of 'affinity for machines' in operation. They are right, but the knack is almost purely a process of reason, and most of the troubles are caused by what old time radio men called a 'short between the earphones,' failures to use the head properly. A motorcycle functions entirely in accordance with the laws of reason, and a study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself."
"If-Then" is a structured logic of humans' thought,who have memories and imagination in their mind. If both don't exist, Then this quote has never even been written."
"It is always easy to be logical. It is almost impossible to be logical to the bitter end."
"Logic is the art of non-contradictory identification. A contradiction cannot exist. No concept man forms is valid unless he integrates it without contradiction into the total sum of his knowledge. To arrive at a contradiction is to confess an error in one's thinking, to maintain a contradiction is to abdicate one's mind and to evict oneself from the realm of reality."

"Whatever the reason we first mustered the _Apollo_ program, however mired it was in Cold War nationalism and the instruments of death, the inescapable recognition of the unity and fragility of the Earth is its clear and luminous dividend, the unexpected final gift of _Apollo_. What began in deadly competition has helped us to see that global cooperation is the essential precondition for our survival.Travel is broadening. It's time to hit the road again."
"When all is said and done, the invention of writing must be reckoned not only as a brilliant innovation but as a surpassing good for humanity. And assuming that we survive long enough to use their inventions wisely, I believe the same will be said of the modern Thoths and Prometheuses who are today devisingcomputers and programs at the edge of machine intelligence."
"She had to fight against developing too combative a personality or becoming altogether a misanthrope. She suddenly caught herself. "Misanthrope" is someone who dislikes everybody, not just men.And they certainly had a word for someone who hates women: "misogynist." But the male lexicographers had somehow neglected to coin a word for the dislike of men. They were almost entirely men themselves, she thought, and had been unable to imagine a market for such a word."
"I don't think science is hard to teach because humans aren't ready for it, or because it arose only through a fluke, or because, by and large, we don't have the brainpower to grapple with it. Instead, the enormous zest for science that I see in first-graders and the lesson from the remnant hunter-gatherers both speak eloquently: A proclivity for science is embedded deeply within us, in all times, places, and cultures. It has been the means for our survival. It is our birthright. When, through indifference, inattention, incompetence, or fear of skepticism, we discourage children from science, we are disenfranchising them, taking from them the tools needed to manage their future."
"Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out."
"Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship."
"Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people."
"Our television signals leave this planet and go out into space...the signals spread out from the earth in spherical waves, a little like ripples in a pond. They travel at the speed of light, 186,000 miles a second, and essentially go on forever. The better some other civilizations receivers are, the farther away they could be and still pick up our tv signals. Even we could detect a strong tv transmission from a planet going around the nearest star.' President: 'You mean everything? You mean to say all that crap on television - the car crashes, wrestling, the porno channels, the evening news?"
"I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But as much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking."
