Moving away from Jacques Derrida's deconstructionism and Paul Ricoeur's hermeneutics, and building on his experiences as a politician, Vattimo asks if it is still possible to speak of moral imperatives, individual rights, and political freedom. Acknowledging the force of Nietzsche's "God is dead," Vattimo argues for a philosophy of pensiero debole or "weak thinking" that shows how moral values can exist without being guaranteed by an external authority. His secularising interpretation stresses anti-metaphysical elements and puts philosophy into a relationship with postmodern culture.
Bringing together twenty-one influential philosophers, theologians, and literary critics, Weakening Philosophy is an important assessment of Vattimo's influence and the major tenets of his thought.
