Abstract

This paper will explore ‘Heidegger’s controversy,’ which has perplexed the scholars for a long time. We need to see whether we can distinguish Heidegger, ‘the philosopher’ from Heidegger ‘the Nazi.’ I would like to suggest that the notion of Geschistlichkeit in Being and Time shows the intimate connections between the fundamental ontology of Dasein and Heidegger’s sympathy for National Socialism. The paper will argue that the analysis of ‘authentic historicality’ in Being and Times shows the link between the authenticity of Dasein and Heidegger’s involvement with National Socialism.
