Book excerpt: William of Ockham (d. 1347) was among the most influential and the most notorious thinkers of the late Middle Ages. In the twenty-seven questions translated in this volume, most never before published in English, he considers a host of theological and philosophical issues, including the nature of virtue and vice, the relationship between the intellect and the will, the scope of human freedom, the possibility of God's creating a better world, the role of love and hatred in practical reasoning, whether God could command someone to do wrong, and more. In answering these questions, Ockham critically engages with the ethical thought of such predecessors as Aristotle, Augustine, Thomas Aquinas, and John Duns Scotus. Students and scholars of both philosophy and historical theology will appreciate the accessible translations and ample explanatory notes on the text.
