How does this book show evidence of the author's views?
The author's views are indicated through the way he presents the characters and the action. Although Hester is an adulteress in the eyes of the law and the church, Hawthorne presents her as a noble and sympathetic character.
In contrast, the way that Hawthorne presents Dimmesdale and Chillingsworth are much less sympathetic.
The author suggests that Hester has true nobility of character, despite her initial transgression, and implies that the Puritan society in which she lives is hypocritical as she is vilified, rather than forgiven, and those who are less worthy are not.
