In Kundera's work, he explores the complex nature of memory, questioning whether memories can be quantified in terms of time. He ponders if recollections have a certain duration and if they develop over time, much like a narrative unfolds in a story. This contemplation reveals the fundamental mystery of memory and its relationship with time.

The unsettling notion arises that our memories, while rich and vivid, lack the temporal essence that allows for true re-experiencing. Unlike rereading a book or rewatching a film, where moments can be revived, our past experiences remain fixed and unchangeable, robbing us of the ability to fully relive them.
