David Farrell Krell is an American philosopher and professor emeritus at DePaul University, specializing in Continental Philosophy. He earned his Ph.D. from Duquesne University, where he focused on Heidegger and Nietzsche, two figures central to his scholarly work. Krell has taught at various universities in the United States and Europe, contributing extensively to the study of German Idealism, Romanticism, and deconstruction. He has authored numerous books, including Daimon Life: Heidegger and Life-Philosophy (1992), Infectious Nietzsche (1996), and The Tragic Absolute: German Idealism and the Languishing of God (2005), examining themes of mortality, time, and finitude. His work also explores the intersections of philosophy, literature, and aesthetics, as seen in Lunar Voices (1995) and Archeticture: Ecstasies of Space, Time, and the Human Body (1997). Krell has been a key translator of Heidegger’s lectures on Nietzsche and edited Basic Writings (1977), a widely used collection of Heidegger’s essays. Influenced by Jacques Derrida, Krell has engaged with deconstructive approaches to Nietzsche and Heidegger, shaping contemporary discussions on these thinkers. His later works, such as Ecstasy, Catastrophe (2015) and The Sea: A Philosophical Encounter (2018), continue his inquiries into existential and aesthetic themes, cementing his reputation as a major voice in modern Continental thought.
