#5 pg 1119: Death of a Salesman

I think the main theme in Death of a Salesman is the idea that our past shapes us into the individual we will be for the rest of our lives. This is shown through the character of Biff. He may not like his father, but because of the environment he was raised in, he will always have little characteristics that he got from his father. This is shown theatrically through Willy's interaction with the ghosts of his memories. He still thinks about his past often. The main thing he thinks about seems to be what his life would be like if he had done things differently.
