"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 on false facts vs. false views, The Descent of Man and Selection in Relation to Sex, 1871. From the series Great Ideas of Western Man.
