In this excerpt from Umberto Eco's "The Island of the Day Before," the speaker contemplates their identity and existence. They reflect on the concept of "I" as not just a momentary presence but as a culmination of all past experiences and memories. This idea suggests that a person's identity is shaped by their history and the memories that define who they are.

Additionally, the speaker emphasizes the importance of current feelings, which arise from a complex interplay of physical and emotional relations within their body. This highlights that one's identity is also influenced by the present sensations and how they connect to past experiences, forming a unique personal reality.
