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.

Another critical theme in The Crucible is the role that hysteria can play in tearing apart a community. Hysteria supplants logic and enables people to believe that their neighbors, whom they have always considered upstanding people, are committing absurd and unbelievable crimes—communing with the devil, killing babies, and so on. In The Crucible, the townsfolk accept and become active in the hysterical climate not only out of genuine religious piety but also because it gives them a chance to express repressed sentiments and to act on long-held grudges. The most obvious case is Abigail, who uses the situation to accuse Elizabeth Proctor of witchcraft and have her sent to jail. But others thrive on the hysteria as well: Reverend Parris strengthens his position within the village, albeit temporarily, by making scapegoats of people like Proctor who question his authority. The wealthy, ambitious Thomas Putnam gains revenge on Francis Nurse by getting Rebecca, Francis’s virtuous wife, convicted of the supernatural murders of Ann Putnam’s babies. In the end, hysteria can thrive only because people benefit from it. It suspends the rules of daily life and allows the acting out of every dark desire and hateful urge under the cover of righteousness.

Reputation is tremendously important in theocratic Salem, where public and private moralities are one and the same. In an environment where reputation plays such an important role, the fear of guilt by association becomes particularly pernicious. Focused on maintaining public reputation, the townsfolk of Salem must fear that the sins of their friends and associates will taint their names. Various characters base their actions on the desire to protect their respective reputations. As the play begins, Parris fears that Abigail’s increasingly questionable actions, and the hints of witchcraft surrounding his daughter’s coma, will threaten his reputation and force him from the pulpit. Meanwhile, the protagonist, John Proctor, also seeks to keep his good name from being tarnished. Early in the play, he has a chance to put a stop to the girls’ accusations, but his desire to preserve his reputation keeps him from testifying against Abigail. At the end of the play, however, Proctor’s desire to keep his good name leads him to make the heroic choice not to make a false confession and to go to his death without signing his name to an untrue statement. “I have given you my soul; leave me my name!” he cries to Danforth in Act IV. By refusing to relinquish his name, he redeems himself for his earlier failure and dies with integrity.

The witch trials empower several characters in the play who are previously marginalized in Salem society. In general, women occupy the lowest rung of male-dominated Salem and have few options in life. They work as servants for townsmen until they are old enough to be married off and have children of their own. In addition to being thus restricted, Abigail is also slave to John Proctor’s sexual whims–he strips away her innocence when he commits adultery with her, and he arouses her spiteful jealousy when he terminates their affair. Because the Puritans’ greatest fear is the defiance of God, Abigail’s accusations of witchcraft and devil-worship immediately command the attention of the court. By aligning herself, in the eyes of others, with God’s will, she gains power over society, as do the other girls in her pack, and her word becomes virtually unassailable, as do theirs. Tituba, whose status is lower than that of anyone else in the play by virtue of the fact that she is black, manages similarly to deflect blame from herself by accusing others.

The witch trials are central to the action of The Crucible, and dramatic accusations and confessions fill the play even beyond the confines of the courtroom. In the first act, even before the hysteria begins, we see Parris accuse Abigail of dishonoring him, and he then makes a series of accusations against his parishioners. Giles Corey and Proctor respond in kind, and Putnam soon joins in, creating a chorus of indictments even before Hale arrives. The entire witch trial system thrives on accusations, the only way that witches can be identified, and confessions, which provide the proof of the justice of the court proceedings. Proctor attempts to break this cycle with a confession of his own, when he admits to the affair with Abigail, but this confession is trumped by the accusation of witchcraft against him, which in turn demands a confession. Proctor’s courageous decision, at the close of the play, to die rather than confess to a sin that he did not commit, finally breaks the cycle. The court collapses shortly afterward, undone by the refusal of its victims to propagate lies.

There is little symbolism within The Crucible, but, in its entirety, the play can be seen as symbolic of the paranoia about communism that pervaded America in the 1950s. Several parallels exist between the House Un-American Activities Committee’s rooting out of suspected communists during this time and the seventeenth-century witch-hunt that Miller depicts in The Crucible, including the narrow-mindedness, excessive zeal and disregard for the individuals that characterize the government’s effort to stamp out a perceived social ill. Further, as with the alleged witches of Salem, suspected Communists were encouraged to confess their crimes and to “name names,” identifying others sympathetic to their radical cause. Some have criticized Miller for oversimplifying matters, in that while there were (as far as we know) no actual witches in Salem, there were certainly Communists in 1950s America. However, one can argue that Miller’s concern in The Crucible is not with whether the accused actually are witches, but rather with the unwillingness of the court officials to believe that they are not. In light of McCarthyist excesses, which wronged many innocents, this parallel was felt strongly in Miller’s own time.
