Ramon Llull

Ramon Llull (1232–1316), also known as Raymond Lull or Lully, was a mathematician, polymath, philosopher, logician, Franciscan tertiary, and writer from the Kingdom of Majorca. He is best known for his Ars Combinatoria, a method aimed at discovering truth by combining basic elements of knowledge through a systematic process.

Designed multiple symbolic representations machines, and pioneered notions of symbolic representation and manipulation to produce knowledge—both of which were major influences on Leibniz.

Ramon Llull, sometimes anglicized as Raymond Lully, was a Catholic philosopher, theologian, poet, missionary, apologist and former knight, born in Palma de Majorca. He invented a philosophical system known as the Art, conceived as a type of universal logic to prove the truth of Christian doctrine to interlocutors of all faiths and nationalities. The Art consists of a set of general principles and combinatorial operations. It is illustrated with diagrams.
