The question of how narratives actually do the work of world-building transcends disciplines: from cosmology to philosophy, digital culture, popular culture, and literary theory. In A New Anatomy of Storyworlds, Marie-Laure Ryan investigates the narratological importance of the concept of world in its various manifestations. She uses a wide array of works-from Sokal's hoax to Maus, from Saussure to Barthes, from Kafka to virtual reality-to interrogate key narratological concepts. By revisiting and redefining concepts such as narrator, plot, character, fictionality, mimesis, and diegesis, Ryan reexamines the major controversies that have enlivened narratology: Does narrative necessarily involve a narrator? Is the notion of implied author useful? Do texts that challenge our experience of the real world require a different narratology? Is the distinction between fictional and factual narratives gradual or binary? Ultimately, Ryan grounds narratology in the concept of world to propose an alternative to the rhetorical, feminist, unnatural, and cognitive approaches that currently dominate the field, thus broadening the frame through which we view story and world-building.
