"There is another connection between infancy and dreams: both are followed by amnesia. When we emerge from either state, we have great difficulty remembering what we have experienced. In both cases, I would suggest, the left hemisphere of the neocortex, which is responsible for analyticrecollection, has been functioning ineffectively."

"An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to uptime causes, we would have to know a great deal more about the Universe than we do now to be sure that no such God exists. To be certain of the existence of God and you be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed."
"We are all flawed and creatures of our times. Is it fair to judge us by the unknown standards of the future?"
"Our difficulties in understanding or effectuatingcommunication with other animals may arise from our reluctance to grasp unfamiliar ways of dealing with the world."
"And despite the insignificance of the instant we have so far occupied in cosmic time, it is clear that what happens on and near Earth at the beginning of the second cosmic year will depend very much on the scientific wisdom and the distinctly human sensitivity of mankind."
"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)"
"[In] everyday life, it is very rare that we are confronted with new facts about events of long ago. Our memories are almost never challenged. They can, instead, be frozen in place, no matter how flawed they are, or become a work in continual artistic revision."
"Neuroanatomy, political history, and introspection all offer evidence that human beings are quite capable of resisting the urge to surrender to every impulse of reptilian core of brain."
"You squeeze the eyedropper, and a drop of pond water drips out onto the microscope stage. You look at the projected image. The drop is full of life - strange beings swimming, crawling, tumbling; high dramas of pursuit and escape, triumph and tragedy. This is a world populated by beings far more exotic than in any science fiction movie..."
"What an astonishing thing a book is. It's a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you're inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly and silently inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of working magic." (1980)"
"But, Jefferson worried that the people - and the argument goes back to Thucydides and Aristotle - are easily misled. He also stressed, passionately and repeatedly, that it was essential for the people to understand the risks and benefits of government, to educate themselves, and to involve themselves in the political process. Without that, he said, the wolves will take over."
