In what and with what effects does Miller present the Keller family?

The only action that occurs within the time frame of the narrative is the revelation of certain facts about the past, and it is important to track how the revelations change the relationships among the characters as well as their own self-definition. Arthur Miller carefully controls the flow of information rather than focusing on plot and action. Thus the play, influenced by the work of the playwright Ibsen, is paced by the slow revelation of facts.
