In 1950 Martin Heidegger published his 1938 lecture “Die Zeit des Weltbildes” in the essay collection Holzwege. He did so in order to document his “inner resistance” after the mid-1930s against the Nazi regime. This text has since been seen as evidence for Heidegger's early rejection of National Socialism and his refusal of a modern ideology that culminated in the totalitarian system. In spite of its influence, the published text has never been compared to the original lecture delivered in 1938. The assessment has now been made, and the differences between the two documents are a striking testimony to the artful falsifications that Heidegger used to re-establish his reputation and philosophical standing after the collapse of the Nazi system.
