“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
