Self, World, and Time takes up the question of the form and matter of Christian ethics as an intellectual discipline. What is it about? How does Christian ethics relate to the humanities, especially philosophy, theology, and behavioral studies? How does its shape correspond to the shape of practical reason? In what way does it participate in the proclamation of the gospel of Jesus Christ? Oliver O'Donovan discusses ethics with self, world, and time as foundation poles of moral reasoning, and with faith, love, and hope as the virtues anchoring the moral life. Blending biblical, historico-theological, and contemporary ideas in its comprehensive survey, Self, World, and Time is an exploratory study that adds significantly to O'Donovan's previous theoretical reflections on Christian ethics.
