Ramon Llull
Inventor of a combinatorial logical system to prove Christian doctrine.
Ramon Llull, born around 1232 in Palma de Mallorca, was a Catholic philosopher, theologian, poet, missionary, and former knight. He created a philosophical system called the Art, a kind of universal logic meant to demonstrate Christian doctrine to people of any faith or background. This system relied on general principles and combinatorial operations, and he illustrated it with diagrams. A highly productive writer, Llull also composed literary works in Catalan to make the Art more widely understood, and he likely wrote in Arabic as well, though none of those texts survive. During his lifetime, his books were translated into Occitan, French, and Castilian.
Llull came from a wealthy Barcelona family that had moved to Majorca after King James I of Aragon conquered the island in 1229. He married Blanca Picany in 1257 and had two children, but later described his earlier life as licentious and worldly, like a troubadour. In 1263, he experienced five visions of Christ on the cross, which inspired him to devote himself to God, convert Muslims to Christianity, and write a definitive book against unbelievers. He sold his possessions, went on pilgrimages, and never returned to his family. Back in Majorca, he bought a Muslim slave to learn Arabic and spent nine years studying Christian and Muslim philosophy. In 1274, while at a hermitage, he received a divine revelation that gave him the form of his Art.
Llull advocated for teaching Arabic and other languages in Europe to aid missionary work. He traveled to meet popes and kings, pushing for colleges to train missionaries. A language school for Franciscans was founded at Miramar in 1276. He went to Tunis around 1291 to preach and debate, and again around 1304, writing letters to the king there. He argued that converting Muslims should come through prayer, not force. In 1311, the Council of Vienne ordered chairs of Hebrew, Arabic, and Aramaic at major universities, fulfilling his goal.
In 1314, at age 82, Llull traveled to Tunis again, possibly because the Hafsid caliph was interested in converting. This time, he faced less interference. In 1315, a mob stoned him in Bougie or Tunis. Though long thought to have died from this and venerated as a martyr, evidence suggests he was rescued by local Christians and died early the next year.
His work was not hugely successful during his life, but it gained a lasting legacy. In the early modern period, his name was linked to alchemy. More recently, he has been seen as a forerunner of social choice theory, predating Borda and Condorcet by 450 years, and his ideas also anticipated computation theory. He is venerated as a saintly figure in the Catholic Church and was beatified in 1847. He was a member of the Third Order of Saint Francis.

Lore & Background
Ramon Llull was a Catholic philosopher, theologian, poet, missionary, apologist, and former knight, born in Palma de Mallorca. He invented a philosophical system called the Art, a type of universal logic designed to demonstrate the truth of Christian doctrine to people of any faith or nationality. The Art relied on general principles and combinatorial operations, often illustrated with diagrams. A prolific writer, he composed works in Catalan to make his Art more accessible, and also wrote in Latin; he likely wrote in Arabic as well, though no Arabic texts survive. His books were translated into Occitan, French, and Castilian during his lifetime. Llull is venerated as a saintly figure in the Catholic Church and was beatified in 1847. He was a member of the Third Order of Saint Francis. His life changed after a series of visions in 1263, which inspired him to devote himself to God, convert Muslims to Christianity, and write a definitive book against unbelievers. He sold his possessions, made pilgrimages, and learned Arabic from a purchased slave. After years of study and contemplation, he received divine revelation for his Art in 1274. He urged the study of Arabic and other languages in Europe, and in 1276 a language school for Franciscan missionaries was founded at Miramar. He traveled to Tunis to preach and dispute with Muslims, and later reported that conversion should come through prayer, not military force. In 1311, the Council of Vienne established chairs of Hebrew, Arabic, and Aramaic at major universities, fulfilling his goal. He died around 1316, possibly after being stoned by a mob in North Africa; his tomb is in Palma.
Reader's Guide
Llull’s Art, which he conceived as a universal logic, was designed to demonstrate Christian doctrine to people of any faith or nationality. It relied on a set of general principles and combinatorial operations, often illustrated with diagrams. He was a prolific writer who produced works in Catalan to make his Art accessible to a broader audience, and he also wrote in Latin and probably Arabic, though no Arabic texts survive. His books were translated into Occitan, French, and Castilian during his lifetime. Although his system did not achieve great success while he lived, it later enjoyed a rich reception. In the early modern period, his name became linked with alchemical writings. More recently, scholars have recognized him as a forerunner of social choice theory, preceding the work of Borda and Condorcet by 450 years, and his ideas also anticipated developments in computation theory. He was a member of the Third Order of Saint Francis and was beatified by Pope Pius IX in 1847. His missionary efforts included urging the study of Arabic and other languages in Europe, and he successfully advocated for chairs of Hebrew, Arabic, and Aramaic at major universities, established by the Council of Vienne in 1311.
