Since our ancestors devoted so much attention to phantasms and left us piles of big books about them, one great department of science must be criticism, by which we discern between the true and the false. There is one historical case of this requirement which always rises before my mind whenever I think of the need of criticism—that is witch-persecution. Although the church had a heavy load of blame for this frightful abuse, yet the jurists were more to blame. As to the church also, the Protestants, especially the Puritans of Scotland, were as bad as the Roman Catholics.
