This paper examines the major works of László Krasznahorkai through the conceptual framework of “Ethical Pessimism,” a term used here to describe his sustained engagement with human suffering, historical catastrophe, and metaphysical uncertainty. Drawing on close readings of Satantango, The Melancholy of Resistance, Seiobo There Below, and Herscht 07769, as well as insights from his 2024 interview with Hari Kunzru in The Yale Review, the study argues that Krasznahorkai’s fiction articulates a distinctive vision of apocalypse as an ongoing process rather than a singular event. His long, unbroken sentences, his depictions of decaying communities, and his fascination with sacred art collectively form a literary method grounded in witnessing—an ethical stance that resists both nihilism and naïve optimism. By situating his work within Hungarian history, European modernism, and global aesthetic traditions, the paper demonstrates how Krasznahorkai’s prose offers a profound critique of technological futurism and the Illusion of Progress, Apocalypse as Process and Ethical Pessimism and the Imperative of Witnessing. Ultimately, the study contends that Krasznahorkai’s fiction affirms the fragile sacredness of everyday human life while refusing the consolations of progress narratives.
