In "The Crucible", what is the affect of Sarah Godd and Tituba's talk about flying south? Why does Miller Include it?
By Act IV, Arthur Miller is highlighting the intolerance of the Puritans, a culture, a group of people, who sought a place where they could worship freely. They themselves have become the persecutors, where once they felt persecuted.
They have jailed innocent people, keeping them in filthy conditions for months. Arthur Miller wants to make it clear to the reader that the Puritan community, a Christian based faith group, has abused and executed innocent people based on fear, paranoia and suspicion for anything that is unexplainable. They have found a way to blame people for their hardships, finding comfort in punishing innocent people.
During this time, anything that the Puritans don't understand falls under suspicion of witchcraft or being in league with the devil. Accusations have been used to further private ambitions, and to rid society of marginalized people like Sarah Good and Tituba.
The two women who have been locked up have gone insane, talking openly and freely, probably wishing, that the devil could actually save them from the horrors of the jail cell.
"The mad ravings of Tituba and Sarah Good are more a reaction against the rigid Puritanism that has condemned them than an embrace of the devil. They have been in jail for many months and are reacting to their circumstances."
