Marcel Proust's In Search of Lost Time is one of the great monuments of modern literature-admired, imitated, and often left unfinished on the nightstand. The Eternal Moment: Marcel Proust and the Architecture of Memory offers a readable, idea-rich companion for libraries, classrooms, and serious general readers.Hamon de Quillan approaches Proust as an architect of consciousness. He shows how the novel cycle is built from recurring materials-sensations, habits, social rituals, works of art-and how these materials construct identity across time. From the madeleine episode to the cork-lined room, from Belle Époque Paris to the disruptions of World War I, the book places Proust's internal drama in its cultural and historical frame without reducing the work to biography.Organised in sixteen thematic chapters, The Eternal Moment examines the formation of Proust's artistic vision; the social "tapestries" of class, salons, and ambition; the mechanics of involuntary memory and sensory recall; love, jealousy, and the illusions of desire; the philosophical currents of Bergson and Schopenhauer; the impact of war on time, perception, and social order; Proust's influence on modernist narrative; and the continuing debates around elitism, style, and accessibility. A final section engages archival materials-letters, photographs, drafts-to show what scholarship can illuminate and where it should remain cautious.Key figures-Swann and Odette, the narrator and Albertine, and the Baron de Charlus-are read as case studies in how society performs itself and how desire distorts perception. Recurrent images (music, flowers, names, rooms) are treated as structural beams that carry meaning from volume to volume, helping readers track continuity across the cycle's celebrated nonlinearity. Ideal for curated literature collections.Clear, interpretive, and generous, de Quillan's study is designed to be used alongside any volume of Proust's cycle. It provides signposts for first-time readers, fresh angles for re-readers, and a vocabulary for discussing Proust's techniques in book clubs or courses on modernism, French literature, narrative theory, and memory studies. A selected bibliography supports further reading.At the centre is a simple promise: Proust's world is vast, but it is navigable. Open the door, follow the sensations, and discover how a single moment can hold an entire life.
