Lorenzo Valla (1407–1457) ranks among the greatest scholars and thinkers of the Renaissance. He secured lasting fame for his brilliant critical skills, most famously in his exposure of the “Donation of Constantine,” the forged document upon which the papacy based claims to political power. Lesser known in the English-speaking world is Valla’s work in the philosophy of language—the basis of his reputation as the greatest philosopher of the humanist movement.

Dialectical Disputations, translated here for the first time into any modern language, is his principal contribution to the philosophy of language and logic. With this savage attack on the scholastic tradition of Aristotelian logic, Valla aimed to supersede it with a new logic based on the actual historical usage of classical Latin and on a commonsense approach to semantics and argument. Valla provides a logic that could be used by lawyers, preachers, statesmen, and others who needed to succeed in public debate—one that was stylistically correct and rhetorically elegant, and thus could dispense with the technical language of the scholastics, a “tribe of Peripatetics, perverters of natural meanings.” Valla’s reformed dialectic became a milestone in the development of humanist logic and contains startling anticipations of modern theories of semantics and language.

Volume 1 contains Book I, in which Valla refutes Aristotle’s logical works on the categories, transcendentals, and predicables, with excursions into natural and moral philosophy and theology.

The Oration by philosopher Giovanni Pico della Mirandola (1463–1494), to which later editors added the subtitle On the Dignity of Man, is the most famous text written in Italy at the height of the Renaissance. The Life of Giovanni by Gianfrancesco Pico, his nephew, is the only contemporary account of the philosopher’s brief and astonishing career—Giovanni, who challenged anyone to debate him on nine hundred theses in Rome, whose writings made him a heretic by papal declaration, died at the age of thirty-one. Together, these works record Giovanni’s invention of Christian Kabbalah, his search for the ancient theology of Orpheus and Zoroaster, and his effort to reconcile all the warring schools of philosophy in universal concord. In this new translation, the two texts are presented with ample explanatory notes that transform our understanding of these fascinating thinkers.

“This book is nothing less than the definitive study of a text long considered central to understanding the Renaissance and its place in Western culture.”
—James Hankins, Harvard University

Pico della Mirandola died in 1494 at the age of thirty-one. During his brief and extraordinary life, he invented Christian Kabbalah in a book that was banned by the Catholic Church after he offered to debate his ideas on religion and philosophy with anyone who challenged him. Today he is best known for a short speech, the Oration on the Dignity of Man, written in 1486 but never delivered. Sometimes called a “Manifesto of the Renaissance,” this text has been regarded as the foundation of humanism and a triumph of secular rationality over medieval mysticism.

Brian Copenhaver upends our understanding of Pico’s masterwork by re-examining this key document of modernity. An eminent historian of philosophy, Copenhaver shows that the Oration is not about human dignity. In fact, Pico never wrote an Oration on the Dignity of Man and never heard of that title. Instead he promoted ascetic mysticism, insisting that Christians need help from Jews to find the path to heaven—a journey whose final stages are magic and Kabbalah. Through a rigorous philological reading of this much-studied text, Copenhaver transforms the history of the idea of dignity and reveals how Pico came to be misunderstood over the course of five centuries. Magic and the Dignity of Man is a seismic shift in the study of one of the most remarkable thinkers of the Renaissance.

The Italian humanist Polydore Vergil (1470-1555) was born in Urbino but spent most of his life in early Tudor England. His most popular work, On Discovery (De inventoribus rerum, 1499), was the first comprehensive account of discoveries and inventions written since antiquity. Thirty Latin editions of this work were published in Polydore's lifetime, and by the eighteenth century more than a hundred editions had appeared in eight languages, including Russian. On Discovery became a key reference for anyone who wanted to know about "firsts" in theology, philosophy, science, technology, literature, language, law, material culture, and other fields. Polydore took his information from dozens of Greek, Roman, biblical, and Patristic authorities. His main point was to show that many Greek and Roman claims for discovery were false and that ancient Jews or other Asian peoples had priority. This is the first English translation of a critical edition based on the Latin texts published in Polydore Vergil's lifetime.

Giannozzo Manetti (1396–1459) was a celebrated diplomat, historian, philosopher, and humanist scholar of the early Renaissance who mastered ancient Greek and Hebrew as well as classical Latin. In this treatise, dedicated to Alfonso of Aragon, King of Naples, Manetti addresses a question central to the anthropology of the Renaissance: what are the moral, intellectual, and spiritual capabilities of the unique amalgam of body and soul that constitutes human nature? The treatise takes issue with a popular work of medieval asceticism, On the Misery of the Human Condition, written by none other than Innocent III, one of the greatest of medieval popes. The pope’s diatribe expresses a revulsion against human nature and argues for the futility of ambition, the emptiness of pleasures, and the ultimate worthlessness of human achievements. Manetti’s treatise presents a comprehensive refutation of the pope’s pessimism, sometimes citing the achievements of the Renaissance as evidence for the potential divinity of human nature and its extraordinary capabilities. This edition contains the first complete translation into English.
