In Mirror Imagery in The Scarlet Letter, Michael Lasser argues that Hawthorne uses mirror imagery to reveal a characters innermost secrets and ulterior motives. The child Pearl is described as, the scarlet letter in another form; the scarlet letter endowed with life!

When Hester and Pearl visit the governors mansion, Hester notices a look of naughty merriment in the little girls eyes. Hawthorne also mentions a fiend that occasionally peeps out of Pearls eyes. Through his description of Hesters impression of the evil that lurks within Pearl, Lasser comments on the notion that Pearl is evil by using the Puritan statement that no good comes from evil.

Lasser explains further that Pearl is not only the embodiment of Hesters sin, but also of her conscience. Lasser explains that Pearl knows her mothers deepest feelings in a way uncommon to a child of her age. Thus, Lasser illustrates that Pearl is used a symbol—a mirror— for Hesters guilt.
