Abstract
Fritz Mauthner’s essay Die Philosophie und der Krieg, published in October 1914, is among the nationalist writings of Mauthner written during the First World War. The essay explores the question of returning to philosophy after the war. Asking this question, Mauthner examines the relationship between war and philosophy and argues that the two concepts do not share any substantial points of contact. During his discussion, an unspoken premise of the question about the return to philosophy is revealed: as the science of reason, philosophy cannot understand war. The profession of philosophy can neither contribute to a military victory nor end the people’s suffering. Hence, philosophers should remain silent in times of war. Mauthner himself did not adhere to his demand. In 1914, he believed that Germany would be victorious, and emphasised in his essay that war reveals a new meaning of life by giving a meaning to death.
