This text illuminates the relevance and importance of Heidegger's thought today.  The chapters address the modern living conditions of intense social transformation intertwined with the continuous and rapid development of technologies that redefine the borders between nations and cultures.  Technology globalizes markets, customs, the exchange of information, and economic flows but also - as Heidegger reminds us - revolutionizes the way we relate to bodies, to life, and to earth, by way of introducing both unprecedented opportunities and great dangers.
