This book offers the first in-depth treatment in English language of Habermas’s long-awaited work on religion, , 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.
