Aristotle's Nicomachean Ethics had a profound influence on generations of later philosophers, not only in the ancient era but also in the medieval period and beyond. In this book, Anthony Celano explores how medieval authors recast Aristotle's Ethics according to their own moral ideals. He argues that the moral standard for the Ethics is a human one, which is based upon the ethical tradition and the best practices of a given society. In the Middle Ages, this human standard was replaced by one that is universally applicable, since its foundation is eternal immutable divine law. Celano resolves the conflicting accounts of happiness in Aristotle's Nicomachean Ethics, demonstrates the importance of the virtue of phronesis (practical wisdom), and shows how the medieval view of moral reasoning alters Aristotle's concept of moral wisdom.

A new book by John Marenbon:

From the turn of the fifth century to the beginning of the eighteenth, Christian writers were fascinated and troubled by the "Problem of Paganism," which this book identifies and examines for the first time. How could the wisdom and virtue of the great thinkers of antiquity be reconciled with the fact that they were pagans and, many thought, damned? Related questions were raised by encounters with contemporary pagans in northern Europe, Mongolia, and, later, America and China.

Pagans and Philosophers explores how writers—philosophers and theologians, but also poets such as Dante, Chaucer, and Langland, and travelers such as Las Casas and Ricci—tackled the Problem of Paganism. Augustine and Boethius set its terms, while Peter Abelard and John of Salisbury were important early advocates of pagan wisdom and virtue. University theologians such as Aquinas, Scotus, Ockham, and Bradwardine, and later thinkers such as Ficino, Valla, More, Bayle, and Leibniz, explored the difficulty in depth. Meanwhile, Albert the Great inspired Boethius of Dacia and others to create a relativist conception of scientific knowledge that allowed Christian teachers to remain faithful Aristotelians. At the same time, early anthropologists such as John of Piano Carpini, John Mandeville, and Montaigne developed other sorts of relativism in response to the issue.

A sweeping and original account of an important but neglected chapter in Western intellectual history, Pagans and Philosophers provides a new perspective on nothing less than the entire period between the classical and the modern world.

A new book by Stephen Read:

The rediscovery of Aristotle in the late twelfth century led to a fresh development of logical theory, culminating in Buridan’s crucial comprehensive treatment in the Treatise on Consequences. Buridan’s novel treatment of the categorical syllogism laid the basis for the study of logic in succeeding centuries.

This new translation offers a clear and accurate rendering of Buridan’s text. It is prefaced by a substantial Introduction that outlines the work’s context and explains its argument in detail. Also included is a translation of the Introduction (in French) to the 1976 edition of the Latin text by Hubert Hubien.
