This book offers the first in-depth treatment in English language of Habermas's long-awaited work on religion, Auch eine Geschichte der Philosophie, published in 2019. Charting the contingent origins and turning points of occidental thinking through to the current "postmetaphysical" stage, the two volumes provide striking insights into the intellectual streams and conflicts in which core components of modern self-understanding have been forged. The encounter of Greek metaphysics with biblical monotheism has led to a theology of history as salvation, expanding in bold arcs from Adam's Fall to Christ and the Last Judgement. The reconstruction of key turns in the relationship between faith and knowledge ends, however, with locating the uniqueness of religion in "ritual" and defining reason as inherently secular.
The book exposes the sources and trajectories, analysed by Habermas with great erudition, to different assessments in biblical studies, theology, and philosophy of subjectivity. Apart from Paul and Augustine, key lines of continuity are identified in the Gospels, early patristic theology, Duns Scotus and Schleiermacher that retain the internal connection of faith to autonomous freedom.
