“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 worth of things can't be measured by what they cost but by what the cost you to get it, that if anything costs you your faith or your family, then the price is too high, and that there are some things that will never wear out.”
― Bob Dylan, Chronicles: Volume One

“For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.”
― Carl Sagan, The Demon-Haunted World: Science as a Candle in the Dark

“The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.”
― Isaac Asimov
