This book attempts to explain the functioning of the combinatorial, semi-mechanical demonstrative techniques of Ramon Llull's 'Art', how it began as an apologetic instrument, how it developed through two main stages, and how it ended trying to reformulate key aspects of medieval Aristotelian logic.

The mnemonic arts and the idea of a universal language that would capture the essence of all things were originally associated with cryptology, mysticism, and other occult practices. And it is commonly held that these enigmatic efforts were abandoned with the development of formal logic in the seventeenth century and the beginning of the modern era. In his distinguished book, Logic and the Art of Memory Italian philosopher and historian Paolo Rossi argues that this view is belied by an examination of the history of the idea of a universal language. Based on comprehensive analyses of original texts, Rossi traces the development of this idea from late medieval thinkers such as Ramon Lull through Bruno, Bacon, Descartes, and finally Leibniz in the seventeenth century. The search for a symbolic mode of communication that would be intelligible to everyone was not a mere vestige of magical thinking and occult sciences, but a fundamental component of Renaissance and Enlightenment thought. Seen from this perspective, modern science and combinatorial logic represent not a break from the past but rather its full maturity. Available for the first time in English, this book (originally titled Clavis Universalis) remains one of the most important contributions to the history of ideas ever written. In addition to his eagerly anticipated translation, Steven Clucas offers a substantial introduction that places this book in the context of other recent works on this fascinating subject. A rich history and valuable sourcebook, Logic and the Art of Memory documents an essential chapter in the development of human reason.

Ramon Lull or Llull created his Art during the 13th century as a method for debating and converting the Islamic kingdoms of North Africa and the Jewish population of Europe, following a vision experienced atop Mount Randa. The Art utilized what is now called combinatoric logic to produce arguments on any subject from simple, mechanical rules, without appeals to authority or existing literature. As such, it forms an important precursor to modern programing languages. In its own right, and through these commentaries by Giordano Bruno, it influenced Gottfried Leibniz and others seeking a universal, logical language; through them, it influenced Boole and later logicians. This is the first English translation of these works. This edition was first published on the 415th anniversary of Bruno's deat

This book presents a comprehensive critical survey of all the logical doctrines of the well-known, but little understood, Catalan philosopher and theologian, Ramon Llull (1232-1316). The first book-length treatment in English of Llull's philosophy to appear in over fifty years, the book defines his contribution to later scholastic culture and to explain exactly how his methods and procedures worked.

For this new anthology, Anthony Bonner has chosen central texts from his acclaimed two-volume compilation Selected Works of Ramon Llull (Princeton, 1985). Available for the first time in an affordable format, these works serve as an introduction to the life and writings of the Catalan (properly, Majorcan) philosopher, mystic, and theologian who lived from 1232 to 1316. Founder of a school of Arabic and other languages, Llull was also a poet and novelist and one of the creators of literary Catalan. This volume contains three prefaces on Llull's life, thought, and reputation. Of Llull's works, it offers Book of the Gentile and the Three Wise Men, his seminal Christian apology; the Ars brevis, a summary of his philosophical system; The Book of the Lover and the Beloved, a celebration of mystical love in the courtly tradition; and his wittily scathing Book of the Beasts.

The authors maintain that Llull was an atypical 'scholar' because he enjoyed a form of access to knowledge that differed from the norm and because he organized the production and dissemination of his writings in a creative and unconventional fashion. Ramon Llull (1232-1316), mystic, missionary, philosopher and author of narrative and poetry, wrote both in Latin and in the vernacular claiming he had been given a new science to unveil the Truth. This book shows why his Latin andvernacular books cannot be read as if they had been written in isolation from one another. Llull was an atypical 'scholar' because he enjoyed a form of access to knowledge that differed from the norm and because he organized theproduction and dissemination of his writings in a creative and unconventional fashion. At a time when learned texts and university culture were conveyed for the most part using the vehicle of Latin, he wrote a substantial proportion of his theological and scientific works in his maternal Catalan while, at the same time, he was deeply involved in the circulation of such works in other Romance languages. These circumstances do not preclude the fact that a considerable number of the titles comprising his extensive output of more than 260 works were written directly in Latin, or that he had various books which were originally conceived in Catalan subsequently translated or adapted intoLatin.

A Companion to Ramon Llull and Lullism offers a comprehensive survey of the work of the Majorcan lay theologian and philosopher Ramon Llull (1232-1316) and of its influence in late medieval, Renaissance, and early modern Europe, as well as in the Spanish colonies of the New World. Llull’s unique system of philosophy and theology, the “Great Universal Art,” was widely studied and admired from the fifteenth through the eighteenth centuries. His evangelizing ideals and methods inspired centuries of Christian missionaries. His many writings in Catalan, his native vernacular, remain major monuments in the literary history of Catalonia.
