In "A Prayer for Owen Meany" by John Irving, the protagonist grapples with the nature of memory and its influence on personal identity. The quote, "You think you have a memory; but it has you!" highlights the idea that memories can dominate our lives, shaping our perceptions and actions more than we realize. It suggests a complex relationship where individuals are often at the mercy of their recollections, indicating that memories can manifest power over one's present and future.

This exploration of memory is central to the narrative, as the characters navigate their pasts and confront the impact of their experiences on their identities. Owen Meany, in particular, embodies this theme as his life is intricately tied to the memories and beliefs of those around him. The story ultimately prompts readers to reflect on how memories affect their lives, urging an understanding of how they can be both a guiding force and a source of constraint.
