The title of the paper expresses the basic thesis, which contains both continuity and polemic. The thinking of the world in the mature phase of Heidegger's work, represented mainly by the volumes Was heißt denken and Unterwegs zur Sprache, is in some ways close to Patocka's and Husserl's motif of the natural world, but both do not reach Heidegger's radicality.
The motif of the natural world is still elaborated in relation to the world of science (even if this relation is understood negatively as the 'pre-scientific world'), whereas the 'world in which we live and die' is the ground on which we land after a decisive 'leap' away from the scientist perspective. The basic contours of such a radically phenomenological world are developed in the essay with the use of the motif of 'way' (non-metaphorically understood) as a 'proto-phenomenon', and the 'horizon' as the specific centre of its dynamics.
