“Reason is the devil’s greatest whore; by nature and manner of being she is a noxious whore; she is a prostitute, the devil’s appointed whore; whore eaten by scab and leprosy who ought to be trodden under foot and destroyed, she and her wisdom . . . Throw dung in her face to make her ugly. She is, and she ought to be, drowned in baptism . . . She would deserve, the wretch, to be banished to the filthiest place in the house, to the closets [i.e. toilets].” - Martin LutherLuther's quote should give pause to those who think it's "common sense" that reason and faith are compatible, and that Christian dogma has always held that there's a positive relationship between the two.
