Ramon Llull

Catalan visionary whose 'Art' sought a universal logic to convert the world.

ScholasticismLate MedievalLatin Christian1232–1316 CE◦ Palma, Majorca13th century CE

Overview

A Majorcan polymath, mystic, and missionary, Ramon Llull invented the 'Ars' (Great Art) — a combinatorial system of basic concepts arranged on rotating figures, meant to generate and demonstrate all truths and to persuade Muslims and Jews of Christianity by reason common to all. Writing prolifically in Catalan, Latin, and Arabic, he anticipated combinatorial logic and computation. He reportedly died a martyr in North Africa.

What they supported — and why

The combinatorial Art

SupportedA fixed set of divine 'dignities' (goodness, greatness, eternity…) can be systematically combined to demonstrate truths in every field.

WhyIf all reality reflects God's attributes, then combining those attributes methodically can generate and prove knowledge universally.

Reason as the ground of interfaith persuasion

SupportedReligious truth can be shown by arguments acceptable to Muslims, Jews, and Christians alike.

WhySince all three share reason and belief in one God, a common rational method could resolve religious difference.

Contemplation and action united

SupportedPhilosophy serves the love and knowledge of God and the conversion of the world.

WhyFor Llull, understanding is inseparable from loving God and serving that love in mission.
