Abstract
According to the author, Heidegger's understanding of the metaphysical roots of modern technology also indicates a way out of its life-threatening grip. Technik und Gelassenheit is an attempt to clear that alternative path according to and after Heidegger. Unaware of the extent of "die ökologische Katastrophe wie das atomäre Inferno," Heidegger was too generous to metaphysics and unable to hope that technology itself would be part of the turn from metaphysics. Schirmacher aims to cultivate that very hope, taking up where Heidegger left off, by developing a notion of the unity of Technik and Gelassenheit.
