"False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for everyone takes a salutary pleasure in proving their falseness; and when this is done, one path towards error is closed and the road to truth is often at the same time opened."
- Charles Darwin

"Be very slow to believe that you are wiser than all others; it is a fatal but common error. Where one has been saved by a true estimation of another's weakness, thousands have been destroyed by a false appreciation of their own strength."
- Charles Caleb Colton
