1232 – 1316
Ramon Llull (c. 1232–1316) was a Majorcan philosopher, theologian, and missionary who developed the Ars Magna, an influential combinatorial logical system aimed at demonstrating Christian truths to Muslims and Jews through rational argument. A prolific author in Latin, Arabic, and Catalan, he stands as a pioneering figure in both formal logic and vernacular philosophical literature. His synthesis of Christian, Islamic, and Neoplatonic thought made him one of the most original thinkers of the medieval period.
