Quote from : The Cambridge Introduction to Marcel Proust Book

Yet the Narrator’s quest is not only for his own identity and vocation. He seeks an understanding of art, sexuality and worldly and political affairs: he is a snoop and a voyeur; he comments and classifies; his taxonomic impulse makes the novel appear to be a vast compendium, replete with burrowing wasps and bedsteads, military strategies, stereoscopes, asparagus and aeroplanes.
