Publisher's description: The Phenomenology of Religious Life presents the text of Heidegger's important 1920621 lectures on religion. First published in 1995 as volume 60 of the Gesamtausgabe, the work reveals a young Heidegger searching for the striking language that eventually formed the mature expression of his thought. The volume consists of the famous lecture course "Introduction to the Phenomenology of Religion," a course on "Augustine and Neoplatonism," and notes for a course on "The Philosophical Foundations of Medieval Mysticism" that was never delivered. Heidegger's engagements with Aristotle, St. Paul, Augustine, and Luther give readers a sense of what phenomenology would come to mean in his later works. Here, Heidegger reveals an impressive display of theological knowledge, protecting Christian life experience from Greek philosophy and defending Paul against Nietzsche. The appearance of this first English translation marks a significant event in Heidegger scholarship and affords a unique look into his phenomenology.
