Raum und Zeit – Stimmung und Grundstimmung – Über Marx

A new review of the Heidegger estate carried out in 2015/16 revealed that there were still some manuscripts in the estate that had not yet been published. As a result, the decision was made to extend the complete edition beyond the original plan. The material in question is now presented in three supplementary volumes to the complete edition with the volume numbers 103, 104 and 105. The first of the three volumes (HGA 103) contains notes on space and time, on disposition ("Stimmung") and on Karl Marx, which were written between 1930 and 1940. The second volume (HGA 104) contains conversations and previously unpublished manuscripts on an as yet undiscovered project of the ‘Vier Hefte’ (GA 104) from 1937 to around 1950. The third volume (HGA 105) is expected to conclude the complete edition in spring 2026 with the publication of Martin Heidegger's last major manuscript from the 1970s, the "Vermächtnis der Seinsfrage" (Legacy of the Question of Being).
