"During many ages there were witches. The Bible said so. The Bible commanded that they should not be allowed to live. Therefore the Church, after doing its duty in but a lazy and indolent way for 800 years, gathered up its halters, thumbscrews, and firebrands, and set about its holy work in earnest. She worked hard at it night and day during nine centuries and imprisoned, tortured, hanged, and burned whole hordes and armies of witches, and washed the Christian world clean with their foul blood. Then it was discovered that there was no such thing as witches, and never had been. One does not know whether to laugh or to cry." [Mark Twain, "Europe and Elsewhere"]
