Abstract

This article seeks to provide a fuller account of the philosophy of religion of the Marburg Neo-Kantian, Paul Natorp (1854–1924), than has hitherto been available. It does so by describing important changes in Natorp’s thinking about religion between the publication of his early book, Religion innerhalb der Grenzen der Humanität (1894), and later writings in which he espouses a version of logos-mysticism strikingly at odds with the concept of a “religion of reason” put forward by his long-time Marburg colleague, Hermann Cohen (1842–1918). These differences are analyzed in relation to these two thinkers’ divergent views on philosophical systematics, and their respective experiences of the First World War.
