“Understanding is a kind of ecstasy”
― Carl Sagan, Broca's Brain: Reflections on the Romance of Science

“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

“The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.”
― Carl Sagan
