one MAY win but Both of us PROFIT

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' & 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

“When I disagree with a rational man, I let reality be our final arbiter; if I am right, he will learn; if I am wrong, I will; one of us will win, but both will profit.”

- Ayn Rand
