The Fundamental Tendency of Our Times (Tendenza) is the Italian philosopher Emanuele Severino’s crucial reflection on modern technology and science, in which he articulates his major contribution to the analysis of Western modernity: the claim that, beginning with Greek civilization, a nihilistic spirit of domination informs our conceptual and social systems. In this book Severino applies his framework to the geopolitical situation before the fall of the Berlin Wall; yet his insights have continuing relevance in light of the current threat of ecological collapse accelerated by an orientation to the world as an object of exploitation. Significant for its parallels with, and differences from, Heidegger's discussion of technology, this book's explicit discussion of politics gives essential clarification to Severino's notoriously complex philosophical discourse. With a foreword contextualizing the historical moment of its publication, this first English translation will be invaluable for those interested in understanding the thought of one of the most remarkable Italian theorists of the 20th century.
