The villagers in Arthur Miller's The Crucible argue about many different things.
-Elizabeth and John Proctor argue about his affair with Abagail Williams.
-Reverend Hale argues with the courts about the reality behind the massive number of villagers being accused of witchcraft.
-Reverend Parris argues with many of the villagers about his pay and lack of silver candlesticks.
-Reverend Parris argues with Abigail Williams about her reputation.
-Some of the villagers argue with each other about the illness of the girls (Betty and Ruth). They believe that they know what is the cause.
-Many of the villagers wrongly accuse others of witchcraft (in order to fuel feuds).
Essentially, the villagers are hysterical given the numerous accusations of witchcraft. Since Tituba confessed to witchcraft, other villagers believe that witchcraft is at work in Salem. With any curious behavior, people are being accused without any true justification. This sets the villagers against each other in very serious arguments.
