The Crucible investigates how mass insanity can obliterate a group. Delirium is most plainly found in the villagers' silly acknowledgment of the young ladies' created cases of witchcraft. One particular case of insanity happens in Act III when the young ladies, drove by Abigail, blame Mary Warren for witchcraft to keep her from affirming against them. In spite of the fact that different individuals (counting Mary) have asserted that the witchcraft allegations are false, the court declines to be influenced.
