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.

Index-learning turns no student pale,
Yet holds the eel of Science by the tail.
Index-learning is a term used to mock pretenders who acquire superficial knowledge merely by consulting indexes.
No matter how much we learn, there is always more knowledge to be gained. In this connection I am reminded of a short poem that has been in my mind over the years. It reads as follow: I used to think I knew I knew. But now I must confess. The more I know I know I know I know I know the less.
O but we dreamed to mend Whatever mischief seemed To afflict mankind, but now That winds of winter blow Learn that we were crack-pated when we dreamed.
The mind of the thoroughly well-informed man is a dreadful thing. It is like a bric-à-brac shop, all monsters and dust, with everything priced above its proper value.
A light has dawned for me: I need companions, living ones, not dead companions and corpses which I carry with me wherever I wish. But I need living companions who follow me because they want to follow themselves- and who want to go where I want to go.
