The Crucible is set in a theocratic society, in which the church and the state are one, and the religion is a strict, austere form of Protestantism known as Puritanism. Because of the theocratic nature of the society, moral laws and state laws are one and the same: sin and the status of an individual’s soul are matters of public concern. There is no room for deviation from social norms, since any individual whose private life doesn’t conform to the established moral laws represents a threat not only to the public good but also to the rule of God and true religion. In Salem, everything and everyone belongs to either God or the devil; dissent is not merely unlawful, it is associated with satanic activity. This dichotomy functions as the underlying logic behind the witch trials. As Danforth says in Act III, “a person is either with this court or he must be counted against it.” The witch trials are the ultimate expression of intolerance (and hanging witches is the ultimate means of restoring the community’s purity); the trials brand all social deviants with the taint of devil-worship and thus necessitate their elimination from the community.
