The following ideas and characters are found in Arthur Miller's play "The Crucible."
Crucible, as defined by Google, is stated as being either "a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures" or "a place or occasion of severe test or trial."
Both definitions fit into Miller's play for different reasons. The first definition can be used to describe he village of Salem as existing as a place where all villagers must adhere to the Puritan way of life so as to "melt" together. Another way to apply "crucible" to the play (with regards to the first definition) is the fact that if one does not adhere to the Puritan way of life they will be forced to face "high temperatures" in regard to the pressure the society will place on them.
The second definition applies to the fact that the villagers of Salem, while in the middle of the witch trials, are facing severe tests and trials.
Elizabeth Proctor is the wife of John Proctor. After firing Abigail Williams for sleeping with her husband, Elizabeth is accused of witchcraft.
Reverend Hale is a minister that Reverend Parris brought to Salem because of his knowledge of witches and witchcraft. Hale had found a witch, who confessed, in his own church and is a noted "specialist" on witches. He is not necessarily called to find witches, but to stop the accusations given Parris' own daughter is thought to be a witch.
John Proctor is a well-known resident of Salem. After having an affair with Abigail Williams, John must decide whether or not to bring her lying about witches to the attention of the courts. Unfortunately to do this, John must admit to his adulterous affair with her.
Insight is the act of seeing into a situation. Insight is important in the play "The Crucible." All of the characters are required to examine the reasons as to why people are being accused of witchcraft. While only a few of the villagers are actually capable of this, insight proves to be of the utmost importance in the action of the play. The insight of the characters is what is required for the accusations to end and the trials to be deemed what they really are--grudges against others which results in hysteria.
