Gianni Vattimo (1936–2023) was among the most significant Italian philosophers of the last fifty years. A controversial figure both at home and abroad, he sometimes described himself paradoxically as a “nihilist” and as a “communist Catholic.” Despite his provocations—and unusually for an academic philosopher—he served two terms in the European Parliament. For decades, Vattimo was at the forefront of developments in continental philosophy, spanning hermeneutics, postmodernity, and the “return to religion.” Drawing on the work of figures such as Heidegger, Marx, Nietzsche, Gadamer, Rorty, and Kuhn, Vattimo constructed his signature concept of “weak thought,” a way of approaching the persistent problems of ideology, violence, and social division after the so-called end of metaphysics. In this book, Thomas Jared Farmer provides a groundbreaking examination of Vattimo’s life and work. He considers the distinctive contributions that Vattimo made to postmodern thought as well as to recent debates in political philosophy and religion. This book provides an accessible introduction to Vattimo’s overall philosophical project while also contextualizing it through discussions of important intellectual figures, key events in Italian history, and details about his personal trajectory. Authoritative and comprehensive, it is an indispensable companion to the works of one of the most original thinkers to emerge in the second half of the twentieth century.
