The fundamental concepts of metaphysics (GA 29/30): internal and external projections

Abstract

This article seeks to show some internal and external projections of the lesson "The fundamental concepts of metaphysics. World, finitude, solitude” developed by Heidegger in the winter semester of 1929/30. The three central ideas that we want to propose are: a) that the lesson GA 29/30 is one of the hinges that allow us to understand the "turn" [Kehre] of Heidegger's thought, since it provides a couple of significant clues, b) that Heidegger himself does not delve in extenso, in later works, one of the topics that most interested me in it: the treatment of the question about the human being and that, therefore, the lesson GA 29/30 constitutes a kind of "higher limit” to these themes. However, this discussion – the question about the human being – is continued by other authors of his time: Max Scheler and Helmuth Plessner and c) that it is possible to identify some references to the lesson GA 29/30 in the Black Notebooks VII-XI of Heidegger, which do not significantly alter what was said above.
