Bence Nancy argues that Musil should also be considered an important philosopher. Musil was trained in philosophy (his Ph.D. thesis was on Ernst Mach) and gave up a promising career in academia when he found the novel a better vehicle for his philosophical ideas.In Robert Musil: Philosophy without Qualities, Bence Nanay argues that Musil's writing reveals original and powerful philosophical views that philosophers today should take seriously. Nanay analyzes Musil's works through a philosophical lens to reveal Musil's contributions to essential questions of free will, moral responsibility, emotions, aesthetics, ethics, and more.Written both for those that know Musil's writings as well as those new to his work, Robert Musil systematically makes a case for why it is not merely of historical interest but is deeply relevant to the problems and concerns of the 21st century.
