Where's Trixi?

This is very true. So many people spend so much energy and time fighting over religion and politics. How many times have I seen someone say you are so right! I am stupid and I need to change my views. None.

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, astronomer and writer (1934-1996)
