Reverend Parris uses many metaphors to get his point across. Elizabeth Proctor uses them to repent.
A metaphor is a comparison. It says that something is something else. For example, consider Reverend Parris’s metaphor here.
There be a faction here, feeding on that news, and I tell you true, sir, I fear there will be riot here. (Act 4)
Obvious, no one literally “feeds” on news. It is a metaphor because the people are so in a frenzy that it is as if they are eating the news. This is an example of a colorful metaphor. Metaphors can be used to add interest to a story, and make it more interesting. They can also characterize, depending on who is using the most metaphors. Parris’s colorful language is appropriate for a preacher. He uses many metaphors. Here is another.
This way, unconfessed and claiming innocence, doubts are multiplied, many honest people will weep for them, and our good purpose is lost in their tears. (Act 4)
The metaphors I have placed in bold continue to make Parris’s point in a nonliteral way. Reverend Parris is used to using words in order to make his point. He likes to exploit words like he exploits people. While he is not the only one to use metaphors, his tendency to whip up emotions to suit his purposes makes good use of them.
The Reverend is not the only one who makes good use of metaphors. Elizabeth also has some good ones. Another example of a metaphor in Act 4 comes from Elizabeth, who says “I have read my heart this three month” and “I have sins of my own to count.” In each case, these metaphors also are useful for characterization. They demonstrate how she is thoughtful, repentant, and self-sacrificing. The inclusion of metaphors for more than one character shows that the people in general are under stress, and experiencing a period of great difficulty. They speak in colorful language because dramatic times call for dramatic language.
