Abstract
This paper is a commemorative contribution on the occasion of the eight decades that have already elapsed since the publication of Sein und Zeit (1927), the work by Martin Heidegger which perhaps has become in the meantime – considerating the enormous scope of its contemporary influence – the most important philosophical treatise of the 20th century. One must draw attention to the fact that it is not purported an elaboration of the work’s reception, which can be almost imposible to embrace in its entirety for it can well be structured in several phases. There is rather an introductory approach to the manuscript’s history before its publication; purpose that can be seen as a more concrete and less ambitious goal in comparison to the main one, which is nothing but to outline the work’s central topics and the pretentions that it has pursued and carried out.
