“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”
― Carl Sagan

“This time I m not going to tell you a story. I'll just say that insanity is the inability to communicate your ideas. It's as if you were in a foreign country, able to see and understand everything that's going on around you but incapable of explaining what you need to know or of being helped, because you don't understand the language they speak there.”
― Paulo Coelho, Veronika Decides to Die

“If you wish to make an apple pie from scratch, you must first invent the universe.”
― Carl Sagan, Cosmos

“From that time on, the world was hers for the reading. She would never be lonely again, never miss the lack of intimate friends. Books became her friends and there was one for every mood. There was poetry for quiet companionship. There was adventure when she tired of quiet hours. There would be love stories when she came into adolescence and when she wanted to feel a closeness to someone she could read a biography. On that day when she first knew she could read, she made a vow to read one book a day as long as she lived.”
― Betty Smith, A Tree Grows in Brooklyn
