The subject of this two-part article is the bearing of Søren Kierkegaard’s writings, and of their reception, upon the development of Religionswissenschaft or the comparative study of religion. This first part opens by taking account of Kierkegaard’s own awareness of, and relationship to, “non-Christian” religions, including his late reading of Schopenhauer; then considers Kierkegaard in juxtaposition with his contemporary F. Max Müller, the Sanskritist and foundational pioneer of comparative religion, and the two men’s contrasting relations to F.W.J. Schelling; and finally (...) examines the interest taken in Kierkegaard by William James, Max Weber, and Gerardus van der Leeuw as early twentieth-century contributors through three different disciplines to the study of comparative religion.
