This article examines the genesis of the concept of destruction in the early lectures of Martin Heidegger between 1919 and 1920. The article claims that, by analyzing the phenomenological framework from which that concept arises, it is possible to reach a better understanding of Heidegger’s philosophical work and its relevance today. The article traces some of the sources of this concept, in particular with reference to Husserl’s concept of Abbau. Subsequently, the paper studies the articulation in the lectures of 1919 (...) and 1920, and finally it puts forward some critical remarks. (shrink)
