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.

One of the leading humanists of Quattrocento Italy, Lorenzo Valla (ca. 1406–1457) has been praised as a brilliant debunker of medieval scholastic philosophy. In this book Lodi Nauta seeks a more balanced assessment, presenting us with the first comprehensive analysis of the humanist’s attempt at radical reform of Aristotelian scholasticism.

This study examines Valla’s attack on major tenets of Aristotelian metaphysics, showing how Valla employed common sense and linguistic usage as his guides. It then explicates Valla’s critique of Aristotelian psychology and natural philosophy and discusses his moral and religious views, including Valla’s notorious identification of Christian beatitude with Epicurean pleasure and his daring views on the Trinity. Finally, it takes up Valla’s humanist dialectic, which seeks to transform logic into a practical tool measured by persuasiveness and effectiveness.

Nauta firmly places Valla’s arguments and ideas within the contexts of ancient and medieval philosophical traditions as well as renewed interest in ancient rhetoric in the Renaissance. He also demonstrates the relevance of Valla’s conviction that the philosophical problems of the scholastics are rooted in a misunderstanding of language. Combining philosophical exegesis and historical scholarship, this book offers a new approach to a major Renaissance thinker.
