What is the role of memory in shaping identity in Person of Interest?

In Person of Interest, memory plays a crucial role in shaping the identity of the characters, particularly the main protagonist, John Reese. Reese is a former CIA agent who has experienced significant trauma, including the death of his girlfriend, Jessica. His memory of these events has a profound impact on his identity and his actions throughout the series.

Throughout the show, Reese's memories are constantly revisited and re-evaluated. They inform his decisions and shape his understanding of himself and the world around him. For example, Reese's memory of Jessica's death motivates him to take action against corrupt individuals and organizations, and his memories of his time in the CIA give him the skills and knowledge needed to fight crime in New York City.

Memory also plays a role in the development of other characters' identities, such as Harold Finch, the creator of the Machine, and Sameen Shaw, a former government assassin. For Finch, memories of his past mistakes and the loss of his best friend have a significant impact on his identity and his desire to create the Machine to prevent future tragedies. Similarly, Shaw's memories of her time as an assassin and her experiences with torture shape her identity and her actions throughout the series.

Overall, memory is a crucial component of identity in Person of Interest. The characters' memories of their past experiences inform their decisions and shape their understanding of themselves and the world around them.
