The philosophical system invented by Ramon Llull, known as the Art, utilized combinatorial operations and diagrams to establish a universal logic for proving Christian doctrine to interlocutors of all faiths. Born in 1232 in the Kingdom of Majorca, Llull spent his life traversing Europe and North Africa, advocating for linguistic education and theological debate over military force.
Early Life and Conversion
Born into a prominent family of Barcelona patricians who arrived in Palma following the conquest by James I of Aragon, Llull lived as a troubadour in his youth. He married Blanca Picany in 1257 and fathered two children, Domènec and Magdalena. However, a series of visions in 1263 triggered a profound shift in his life. He sold his possessions, modeled his existence after Saint Francis of Assisi, and committed himself to missionary work and the refutation of errors held by unbelievers.

In 1274, while residing at a hermitage on Puig de Randa, Llull experienced a divine revelation that provided the structure for his philosophical system. The resulting Art functioned as an iterative process, proving truths about God by analyzing His essential attributes through combinatorial logic. To disseminate these ideas, he authored extensive works in medieval Latin and Old Catalan, including the Tree of Science and the Book of the Gentile and the Three Wise Men.
Missionary Advocacy
Llull believed that effective conversion required the study of languages, particularly Arabic, Hebrew, and Chaldean. He successfully lobbied for the establishment of specialized chairs at major universities including Bologna, Oxford, Paris, and Salamanca, a goal realized by the Council of Vienne in 1311. His missionary travels led him to Tunis multiple times, where he engaged in philosophical discourse with local authorities.
Legacy and Veneration
Following a final journey to Tunis in 1314, Llull reportedly suffered a violent assault. Although legends emerged describing him as a martyr, historical accounts indicate he was likely rescued and died in 1316 while returning to Mallorca. He was buried at the Basilica of St. Francis. In 1847, Pope Pius IX beatified him. Modern scholars recognize his combinatorial methods as precursors to both computation theory and social choice theory.
