Hale establishes his authority with the books. He takes lots of "weighted with authority books". These books contain the authority. He looks like a well-educated and learned man. However, Hale's knowledge about witchcraft cannot be scientifically corroborated.
<span>In his opening remarks, Hale seems to establish authority by going directly to his idea on finding out who the witch is because of this Abigail points Tituba as a witch for doing witchery. this lead to Tituba confessing but later on she starts accusing other for witchery</span>
