In Joyce Carol Oates' novel "Carthage," the idea that strong love from at least one person is essential for one's existence is a central theme. The character Sabbath exemplifies this, implying that for her to truly feel alive and valued, she must be deeply cherished by someone significant in her life. Haley represents that crucial connection for Sabbath, highlighting the importance of passionate relationships in our lives. Without such bonds, our sense of self can become diminished.

The bond between Sabbath and Haley demonstrates how love can define one's identity and existence. This notion resonates throughout the narrative, suggesting that human connections are vital for emotional survival. Oates intricately explores the complexities of love, longing, and the need for validation in our relationships, making it evident that being loved fiercely enables individuals to navigate their truths and challenges more profoundly.
