In Joyce Carol Oates' book "Carthage," the protagonist struggles with her sense of self-worth, believing she lacks an intrinsic identity. From a young age, she has felt that her existence is merely a reflection of how others perceive and love her, rather than a solid foundation rooted in her own individuality. This belief leads her to question her own value and purpose, as she feels reliant on external validation for her sense of self.

The narrative delves into the complexities of her self-perception and the emotional toll it takes on her. As she grapples with this internal conflict, the story explores themes of identity, love, and the impact of societal expectations on one's self-image. Oates poignantly illustrates the protagonist's journey, emphasizing the challenge of finding true self-acceptance in a world that often defines individuals through the lens of others.
