What We Can Know Summary: A Lost Masterpiece Unveiled

I’ve always felt a unique thrill when Ian McEwan releases a new novel, and What We Can Know is no exception. From the moment I opened its pages, I sensed a story that would confront me with both intellectual challenge and emotional resonance. Imagine a masterpiece lost to time, revered for generations, but built on a lie only one person knows—and that secret waits to unravel.

McEwan explores enormous questions: Can we ever truly know someone? How does guilt shape human behavior? In a post-catastrophe 22nd-century world, the remnants of the past collide with personal obsession, art, and memory.

The narrative spans from a 2014 dinner party—the infamous “Second Immortal Dinner”—to 2119, a flooded world struggling to preserve knowledge and culture. Through Thomas Metcalfe, a scholar obsessed with reconstructing a lost poem, I confronted these questions head-on.

His journey reveals that the celebrated poem A Corona for Vivien—once considered a cultural treasure—was born of personal sacrifice and betrayal. The book isn’t just a story; it’s a meditation on history, morality, and what it means to preserve truth over myth.
