As for the evocative title of his book, Søren Riis’ objective is to ‘unframe’ Heidegger’s concept of enframing. His book offers an exegetically precise reading of QCT but also, and more importantly, a novel way of interpreting it by examining some of Heidegger’s other works. . . . Riis’ book can contribute to a serious discussion on why and how Heidegger’s QCT is read and taught in many departments.

The Danish philosopher Søren Riis is one of the authorities I trust most when it comes to Heidegger. He has a rare combination of scholarly mastery of Heidegger's texts and up-to-date awareness of the latest trends in the philosophy of technology. His respect for the reader's intelligence also makes reading his works an unusually pleasant experience. I am delighted to see this work finally being published in English.

A faithful, painstaking and subversive many-worlds rereading of Heidegger. It might be Heidegger’s ‘supreme danger,’ but perhaps enframing is not so bad after all.
