How was alienation displayed in The Crucible?

Alienation is woven throughout the plot of The
Crucible and involves many of the characters. Tituba is alienated from the
town of Salem because of her race and the perception that she is a witch. Abigail is
alienated first from the Proctor family and then from Salem as a whole because of her
lies. Mary Warren is alienated from the other girls because she threatens to expose the
truth. John Proctor is alienated from his wife because of his affair and then alienates
himself from his own faith and religion in response to the town's accusations. Mr. Hale
is alienated from his own sense of truth and reality because of what he observes in the
town. These are just few of examples of alienation throughout the
play.
