Three literary techniques seem inherent in this passage: character development, external conflict, and the use of metaphor. Expand more on this.
The Crucible Writing Style:
Simple, old-fashioned-
The dialogue is the simple language of country folks, while at the same time employing old-fashioned vocabulary and grammar. The narrative asides are slightly more complex and use regular, standard, 1950s everyday language.
Critical-
The tone Miller adopts towards the subject of witch trials and witch-hunts, and towards the characters that perpetuate them, is unequivocally critical. He is sympathetic towards individual characters who are the victims, such as the Proctors or Rebecca Nurse.
Drama
The Crucible is a four-act dramatic play, produced on Broadway and later made into a film. It uses pure dialogue to convey the tension, resolution, and themes, with a few directions for action. It was intended to be performed rather than read. Though most people nowadays experience the play on the page, it really works best as a stage production.
