In Defense of Common Sense

One of the leading humanists of Quattrocento Italy, Lorenzo Valla (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, employing 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 recent interest in ancient rhetoric. 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.
