Quotes

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. Carl Sagan
There is child abuse, and there are such things as repressed memories. But there are also such things as false memories and confabulations, and they are not rare at all. Misrememberings are the rule, not the exception. They occur all the time. They occur even in cases where the subject is absolutely confident - even when the memory is a seemingly unforgettable flashbulb, one of those metaphorical mental photographs. Carl Sagan
Carl Sagan quote: "Books break the shackles of time, proof that humans can work..."
Books break the shackles of time, proof that humans can work magic. Carl Sagan
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. Carl Sagan
If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read. Carl Sagan
The lifetime of a human being is measured by decades, the lifetime of the Sun is a hundred million times longer. Compared to a star, we are like mayflies, fleeting ephemeral creatures who live out their lives in the course of a single day. Carl Sagan
The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small. Carl Sagan
The immense distances to the stars and the galaxies mean that we see everything ins pace int he past, some as they were before the Earth came to be. Telescopes are time machines. Carl Sagan
It seems to me what is called for is an exquisite balance between two conflicting needs: the most skeptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas...If you are only skeptical, then no new ideas make it through to you? On the other hand, if you are open to the point of gullibility and have not an ounce of skeptical sense in you, then you cannot distinguish the useful ideas from the worthless ones. Carl Sagan
By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang. Carl Sagan
Carl Sagan quote: "My wonder button is being pushed all the time."
My wonder button is being pushed all the time. Carl Sagan
Once upon a time, we soared into the Solar System. For a few years. Then we hurried back. Why? What happened? What was 'Apollo' really about? Carl Sagan
