Challenging the idea that nihilism has supplanted metaphysics, Vittorio Possenti finds in this philosophical turn the grounds for a mature renewal of metaphysics. Possenti takes the reader on a "third voyage" that goes beyond the "second voyage" indicated by Plato in the Phaedo. He traces the ascendancy of nihilism in philosophy, offering critical examinations of Nietzsche, Gentile, Heidegger, Habermas, Husserl, Gadamer, Ricoeur, and Vattimo. With penetrating accounts of philosophical movements such as hermeneutics and logical empiricism, rich with both historical and theoretical insights, Possenti provides a compelling defense of the power of human reason to apprehend the most obvious but also the most profound aspect of things: that they exist. By exploring the ubiquity of nihilism and probing its philosophical roots, Possenti clears the way for a fresh reformulation of metaphysics.
