From Technological Humanity to Bio-technical Existence can be framed as a metaphysics of the present. It starts from the current epoch, an era increasingly marked not only by technology but also by technics in the most general sense, and asks how this affects human existence. The book asks what is called technics, what is called humanity, how these relate to one another, and how changes in these notions oblige us to revise the philosophical notion of existence. It investigates how the idea of technological humanity--of technology as an extension and instrument of the human--is discovered and deconstructed by Martin Heidegger, Helmuth Plessner, Michel Foucault, Jacques Derrida, Bernard Stiegler, and Giorgio Agamben. Finally, the book presents a new idea of bio-technical existence, one that underlies these philosophers' works without being fully elaborated. This idea--of technics as a condition of humanity that humans share with other living and technical beings--is the author's own philosophical proposition and the final result of the book.
