The Number Sense asks what kinds of work, intellectual and ethical, literature's numerical figures perform. Why are some writers especially prone to include numbers? What affordances do they wield in various literary environments and against the backdrop of the numbery nineteenth century? When do textual numbers really count and when do they ask us to keep count? How do they stage contests between the one and the many, individuals and collectives? How do they relate to formal aspects of works, like plot and character, narrative, and lyric Lingering over literary measures illuminates the way numbers help shape texts into the recognizable forms we call genres. To that end, the book considers the works of poets, like Tennyson, Wordsworth, and Byron, and of novelists working in a broad range of genres, including Jane Austen, George Gissing, Charles Dickens, Anthony Trollope, Lewis Carroll, Bram Stoker, Wilkie Collins, and Thomas Hardy. The numbers embedded in their fictions and verse can serve both as valves, releasing cultural pressures, and as fulcrums, places where pressures coincide to create new forms of literary agency.
