By July of 1915 the young Dr. Martin Heidegger was ready to apply for a license to teach at Freiburg University.¹ Two years earlier, in the summer of 1913, he had obtained the doctorate in philosophy with his inaugural dissertation, The Doctrine of Judgment in Psychologism. He had then set to work on his qualifying dissertation (Habilitationsschrift), but events had conspired to interrupt him. On August 1, 1914 the First World War broke out, and between August and October Heidegger was in and out of active military service twice, both times with Infantry Reserve Battalion 113, once as a volunteer (ca. August 2–10, 1914) and once as a draftee (October 9–20, 1914). In both cases he was dismissed for reasons of health.²
