Abstract: Adolf Reinach (1883–1917) was a German phenomenologist and legal theorist. This is a previously-unpublished translation (by Dr. Berit Brogaard) of Reinach’s 1905 dissertation for his PhD earned under Theodor Lipps at the University of Munich, which was published as “Über den Ursachenbegriff im geltenden Strafrecht” (Leipzig: J. A. Barth 1905), and reprinted in Adolf Reinach, Sämtliche Werke. Textkritische Ausgabe [Collected Works: Critical Edition], Karl Schuhmann & Barry Smith, eds., 2 vols. (Munich: Philosophia Verlag, 1989), pp. 1–43.
