Since the seminal 1955 habilitation by Heidegger's pupil, Walter Schulz, it has become an open secret that Schelling's philosophy, more than that of any of the other German Idealists, is an immediate antecedent to Heidegger's thought. For this reason, it is all the more fascinating that to this day research is still lopsidedly concerned with the interpretation of Heidegger's reading of Schelling's Freedom Essay and that a thorough and overarching investigation into the idealistic inheritance of Martin Heidegger's thought remains wanting. (...) The same applies to the debates that Heidegger's students began in the twentieth century. The traditions of modern nature ethics and the criticism of technology, which derive from Schelling, were interpreted and mediated through Heidegger to his students Hans Jonas, Hannah Arendt, and Günther Anders. This essay attempts to delineate some of the basic features of a more bilateral or dialogical relationship between these two philosophers and to more fully appreciate Heidegger's relationship to German Idealism in general and Schelling in particular.
