Mark Twain var en av förra sekelskiftets mest framstående författare och skeptiker. Nedan följer avslutningen på essän Bible Teaching and Religious Practice:
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 eight hundred 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. Who discovered that there was no such thing as a witch - the priest, the parson? No, these never discover anything. At Salem, the parson clung pathetically to his witch text after the laity had abandoned it in remorse and tears for the crimes and cruelties it has persuaded them to do. The parson wanted more blood, more shame, more brutalities; it was the unconsecrated laity that stayed his hand. In Scotland the parson killed the witch after the magistrate had pronounced her innocent; and when the merciful legislature proposed to sweep the hideous laws against witches from the statute book, it was the parson who came imploring, with tears and imprecations, that they be suffered to stand.
There are no witches. The witch text remains; only the practice has changed. Hell fire is gone, but the text remains. Infant damnation is gone, but the text remains. More than two hundred death penalties are gone from the law books, but the texts that authorized them remain.
It is not well worthy of note that of all the multitude of texts through which man has driven his annihilating pen he has never once made the mistake of obliterating a good and useful one? It does certainly seem to suggest that if man continues in the direction of enlightenment, his religious practice may, in the end, attain some semblance of human decency.
