Can you explain this Good men never interpret themselves too meanly Scarlet Letter?

In Nathaniel Hawthorne's The Scarlet Letter, the phrase" Good men never interpret themselves too meanly" suggests that individuals with noble and virtuous character tend not to undervalue or underestimate their own worth or capabilities. This idea aligns with the Puritan belief in the inherent goodness of humanity, particularly among those striving to live righteous lives. According to this perspective, individuals who possess a strong moral compass and actively seek to do what is right for themselves and society tend to have a positive self-perception.

The opposite is also true in Hawthorne's novel. Characters who engage in sinful or immoral acts, such as Arthur Dimmesdale and Roger Chillingworth, experience a decline in their self-worth. Dimmesdale, who commits adultery with Hester Prynne and conceals his sin for years, is plagued by guilt and shame, leading him to view himself as unworthy and deserving of punishment. Chillingworth, who becomes consumed with revenge against Dimmesdale, also experiences a moral decay that negatively affects his self-perception. He is willing to sacrifice his own well-being and reputation in his quest for retribution, ultimately diminishing his own sense of worth.

Therefore, the phrase "Good men never interpret themselves too meanly" serves as a moral lesson in The Scarlet Letter, highlighting the importance of living a virtuous life and maintaining a positive self-image. It suggests that individuals who engage in noble and honorable actions are more likely to cultivate a healthy sense of self-esteem and self-worth.
