The book deals with key ethico-political issues of modernity, that of responsibility and of the subject(s) that can assume it. Today, new realities, from global political issues to economic crises and lack of confidence in governments, show that there is no authority, institution, or public organism capable of taking charge. In fact, people find themselves less responsible than ever before.Available for the first time in English, this text by one of the leading European intellectuals explores why we need to return to a full personal responsibility. This entails a revisiting of such concepts as personal identity, tolerance, and action all essential components of responsibility. Featuring a preface by Gianni Vattimo, the book not only analyzes the problem of responsibility from various perspectives (including Nietzsche, Weber, Arendt, Sartre), but also confronts todays realities and challenges. As Cruz puts it, Until now, men attempted to describe the world; the moment has arrived for them to take it on.
