Leonardo Boff, a Brazilian theologian and public intellectual, was one of the foundational voices of Latin American liberation theology. Since those early years he went on to enlarge his perspective by integrating an option for the poor with an “option for the earth,” as well as drawing on insights from world religions, indigenous spirituality, the new cosmology, and feminist thought. In this book, written from the perspective of his 80th birthday, he overviews the principle themes of his work beginning with the role of dreams―the capacity to imagine alternatives―before returning to reflection on God, Jesus, the Holy Spirit, the Church, ecotheology, a “universal ethic for the common good,” and spirituality.
