The Coda sketches how the distinctive tradition of uncertainty in nineteenth-century literature and culture changes with the rise of literary modernism. Uncertainty remains of vital interest to writers like Henry James, D. H. Lawrence, James Joyce, Virginia Woolf, and E. M. Forster. Yet a more self-conscious embrace of chance, contingency, and randomness, alongside a more thoroughgoing skepticism, disengages this writing from the earlier literature’s concerns. Further valences acquired by the concept of uncertainty in the early twentieth century – as radical indeterminacy in physics and contrast class to risk in economics – both intensify cultural interest in the topic and disarticulate its nineteenth-century framework. In a reading of Joseph Conrad’s novel Chance (1914), I argue that his emphasis on the value of momentary judgments, on knowledge as mercurial and provisional, and on the role of accident in literary plots all reprise Victorian tactics.
