Abstract
For Heidegger, the modern understanding of beeing is located within the space-time horizon of metaphysics in the form of a nihilistic "will to power", which makes it increasingly difficult for it to free itself from metaphysical thinking. With the progress and success of science and technology, the addiction of the modern age to metaphysics even seems to increase; man will ultimately be brought into the closed horizon of a tragic and nihilistic interpretation of beeing. The age of enlightenment, is in fact - according to the thesis of the author - not yet at an end: Only if enlightenment, through basic "philosophical thought", reflects on its own foundation in a more fundamental and critical way and really makes the "turning" ("Kehre"), might it be able to overcome its unexplored addiction to the horizon of metaphysics, as well as to overcome modern man's alienation of the self and being, and to find its way back to the Greek beginnings of western thought.
